Why Do Emerging Economies Borrow Short Term?  

E-Print Network (OSTI)

We argue that emerging economies borrow short term due to the high risk premium charged by international capital markets on long-term debt. First, we present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders. By issuing long-term debt, the government lowers the probability of a liquidity crisis, transferring risk to bondholders. In equilibrium, this risk is reflected in a higher risk premium and borrowing cost. Therefore, the government faces a trade-off between safer long-term borrowing and cheaper short-term debt. Second, we construct a new database of sovereign bond prices and issuance. We show that emerging economies pay a positive term premium (a higher risk premium on long-term bonds than on short-term bonds). During crises, the term premium increases, with issuance shifting toward shorter maturities. This suggests that changes in bondholders ’ risk aversion are important to understand emerging market crises.

Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook April 2003 Overview World Oil Markets. Crude oil prices fell sharply at the onset of war in Iraq, but the initial declines probably overshot levels that we consider to be generally consistent with fundamental factors in the world oil market. Thus, while near-term price averages are likely to be below our previous projections, the baseline outlook for crude oil prices (while generally lower) is not drastically different and includes an average for spot West Texas Intermediate (WTI) that is close to $30 per barrel in 2003 (Figure 1). The mix of uncertainties related to key oil production areas has changed since last month, as Venezuelan production has accelerated beyond previous estimates while Nigerian output has been reduced due to internal conflict.

Solid growth in world oil demand this winter (and for 2003 as a whole) is likely to tighten world oil markets and reduce commercial oil inventories. The West Texas Intermediate (WTI) crude oil spot price averaged $29.75 in September, about $3.50 per barrel above the year-ago level and about $10 per barrel above a low point seen last January.

Short-term energy outlook: Quarterly projections  

SciTech Connect

The Energy Information Administration (EIA) quarterly forecasts of short-term energy supply, demand, and prices are revised in January, April, July, and October for publication in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes previous forecast errors, compares recent projections by other forecasters, and discusses current topics of the short-term energy markets (see Short- Term Energy Outlook: Annual Supplement, DOE/EIA-0202). The principal users of the Outlook are managers and energy analysts in private industry and government. The projections in this volume extend through the fourth quarter of 1990. The forecasts are produced using the Short-term Integrated Forecasting System (STIFS). The STIFS model uses two principal driving variables: a macroeconomic forecast and world oil price assumptions. Macroeconomic forecasts produced by data Resources, Inc., (DRI), are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic forecast. EIA's Oil Market Simulation Model is used to project world oil prices. 20 refs., 17 figs., 16 tabs.

Short-term energy outlook. Quarterly projections  

SciTech Connect

Energy Information Administration (EIA) quarterly forecasts of short-term energy supply, demand, and prices are revised in February, May, August, and November for publication in the Short-Term Energy Outlook, quarterly projections. Methodology volumes, which are published with the May and November issues, contain descriptions of the forecasting system and detailed analyses of the current issues that affect EIA's short-term energy forecasts. The forecasts are produced using the Short-Term Integrated Forecasting System (STIFS). Two principal driving variables are used in the STIFS model: the macroeconomic forecast and the world oil price assumptions. The macroeconomic forecasts, which are produced by Data Resources, Inc., (DRI), are adjusted by EIA in cases where EIA projections of the world price of crude oil differ from DRI estimates. EIA's Oil Market Simulation Model is used to project the world oil prices. The three projections for petroleum supply and demand are based on low, medium, and high economic growth scenarios which incorporate high, medium, and low crude oil price trajectories. In general, the following discussion of the forecast refers to the medium, or base case, scenario. Total petroleum consumption sensitivities, using varying assumptions about the level of price, weather, and economic activity are tabulated.

In addition, printed versions of the report are available to subscribers in January, April, July and October. The forecast period for this issue of the Outlook extends from July 1998 through December 1999. Values for second quarter of 1998 data, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the July 1998 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. 28 figs., 19 tabs.

Short-Term Energy Outlook- May 2003  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook May 2003 Overview World Oil Markets. The April 24 meeting of the Organization of Petroleum Exporting Countries (OPEC) raised official quotas for members (excluding Iraq) by 0.9 million barrels per day from the previous (suspended) quota to 25.4 million barrels per day. OPEC members also sought tighter compliance with quotas, calling for production cuts of 2 million barrels per day from April levels. We expect these measures to result in an average total OPEC (including Iraq) crude oil production rate of about 26.7 million barrels per day in the second and third quarters. This production level is not significantly different from our base case assumptions in last month's report. Individual OPEC country shares of these output levels will depend upon the speed with which

However, by the end of November oil prices had risen to end-October levels as concerns over the situations in Iraq and Venezuela pushed prices up. Oil inventories, which are currently in the lower portion of the previous 5-year range, are poised to rise to more comfortable levels soon if OPEC output continues at or above current levels. OPEC is considering cutbacks from current levels. Heating Fuels Update. As in October, weather was m uch colder than normal in November, boosting

The forecast Brent crude oil spot price falls to an average of $100 per barrel in 2013. The projected West Texas Intermediate (WTI) crude oil spot price discount to Brent crude oil narrows from about $14 in the third quarter of 2012 to $9 by late 2013. These price forecasts assume that world oil-consumption-weighted real gross domestic product (GDP), which increased by 3.0 percent in 2011, grows by 2.8 percent in 2012 and 2.9

EIA expects that the Brent crude oil spot price will average $102 per barrel over the second half of 2013, and $100 per barrel in 2014. * EIA expects the price of regular gasoline will average $3.53 per gallon over the summer driving season (April through September). The annual average regular gasoline retail price is projected to decline from $3.63 per gallon in 2012 to $3.49 per gallon in 2013 and to $3.37 per gallon in 2014.

3 3 1 Short-Term Energy Outlook February 2003 Overview World Oil Markets. World oil markets will likely remain tight through most of 2003, as petroleum inventories and global spare production capacity continue to dwindle amid blasts of cold weather and constrained output from Venezuela. OPEC efforts to increase output to make up for lower Venezuela output has reduced global spare production capacity to only 2 million barrels per day, leaving little room to make up for unexpected supply or demand surprises. Meanwhile, the average West Texas Intermediate (WTI) crude oil price increased by $3.50 to $33 per barrel from December to January (Figure 1). For the year 2003, WTI oil prices are expected to remain over $30 per barrel, even though Venezuelan output appears to be moving toward normal sooner than expected. Also,

November 2002 November 2002 1 Short-Term Energy Outlook November 2002 Overview World Oil Markets: During the past 3-4 months, OPEC 10 production has risen more quickly than projected, thus reducing upward pressure on prices. More specifically, while the West Texas Intermediate (WTI) crude oil spot price averaged $28.84 in October, about $6.70 per barrel above the year-ago level (Figure 1), the WTI average price for fourth quarter 2002 is now projected to soften to $28.20, which is about $2 per barrel below our fourth-quarter projection from last month. Meanwhile, OECD inventory levels, which are now approaching 5 -year lows, should begin to rise over the next few months as additional supplies reach markets, and return to the middle of their observed range by spring.

Short-Term Test Results: Multifamily Home Energy Efficiency Retrofit  

SciTech Connect

Multifamily deep energy retrofits (DERs) represent great potential for energy savings, while also providing valuable insights on research-generated efficiency measures, cost-effectiveness metrics, and risk factor strategies for the multifamily housing industry. The Bay Ridge project is comprised of a base scope retrofit with a goal of achieving 30% savings (relative to pre-retrofit), and a DER scope with a goal of 50% savings (relative to pre-retrofit). The base scope has been applied to the entire complex, except for one 12-unit building which underwent the DER scope. Findings from the implementation, commissioning, and short-term testing at Bay Ridge include air infiltration reductions of greater than 60% in the DER building; a hybrid heat pump system with a Savings to Investment Ratio (SIR) > 1 (relative to a high efficiency furnace) which also provides the resident with added incentive for energy savings; and duct leakage reductions of > 60% using an aerosolized duct sealing approach. Despite being a moderate rehab instead of a gut rehab, the Bay Ridge DER is currently projected to achieve energy savings ? 50% compared to pre-retrofit, and the short-term testing supports this estimate.

(STEO) (STEO)  This edition of the Short-Term Energy Outlook is the first to include forecasts for 2014.  EIA expects that the Brent crude oil spot price, which averaged $112 per barrel in 2012, will fall to an average of $105 per barrel in 2013 and $99 per barrel in 2014. The projected discount of West Texas Intermediate (WTI) crude oil to Brent, which averaged $18 per barrel in 2012, falls to an average of $16 per barrel in 2013 and $8 per barrel in 2014, as planned new pipeline capacity lowers the cost of moving Mid-continent crude oil to the Gulf Coast refining centers.  EIA expects that falling crude prices will help national average regular gasoline retail prices

Gasoline and Diesel Fuel Update (EIA)

April 2005 April 2005 1 Short-Term Energy Outlook April 2005 2005 Summer Motor Gasoline Outlook (Figure 1) Gasoline prices in 2005 are projected to remain high, at an expected average of $2.28 per gallon for the April to September summer season, 38 cents above last summer. Similar high motor gasoline prices are expected through 2006. Monthly average prices are projected to peak at about $2.35 per gallon in May. Summer diesel fuel prices are expected to average $2.24 per gallon. As in 2004, the primary factor behind these price increases is crude oil costs. WTI, for example, is projected to average 37 cents per gallon higher than last summer. High world oil demand will continue to support crude oil prices and increase competition for

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

8 per MMBtu during the last 2 months of 2003 and increase to $4.36 in January 2004 (Short-Term Energy Outlook, November 2003). Prices have fallen in the past few months as mild weather and reduced industrial demand have allowed record storage refill rates. As of October 31, 2003, working gas levels had reached 3,155 Bcf, which is about 3 percent higher than the 5-year average and the first time since October 2002 that stocks exceeded the year-earlier levels. With the improved storage situation, wellhead prices during the current heating season (November through March) are expected to be about 12 percent less than last winter ($4.12 vs. $4.68 per MMBtu). However, prices in the residential sector will likely be about 8 percent higher than last winter, as accumulated natural gas utility costs through 2003 are recovered in higher household delivery charges. Overall in 2003, wellhead prices are expected to average $4.76 per MMBtu, which is nearly $2 more than the 2002 annual average and the largest year-to-year increase on record. For 2004, wellhead prices are projected to drop by nearly $0.90 per MMBtu, or about 18 percent, to $3.88 per MMBtu as the overall supply situation improves.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

Summary from the Short-Term Energy Outlook Summary from the Short-Term Energy Outlook EIA Home > Natural Gas > Natural Gas Weekly Update Natural Gas Summary from the Short-Term Energy Outlook This summary is based on the most recent Short-Term Energy Outlook released May 6, 2002. EIA projects that natural gas wellhead prices will average $2.73 per MMBtu in 2002 compared with about $4.00 per MMBtu last year (Short-Term Energy Outlook, May 2002). This projection reflects the sharp increases in spot and near-term futures prices in recent weeks. Average wellhead prices have risen 38 percent from $2.14 per MMBtu in February to an estimated $2.96 in April. Spot prices at the Henry Hub have increased to an even greater extent, rising more than $1.50 per MMBtu since early February. The upward price trend reflects a number of influences, such as unusual weather patterns that have led to increased gas consumption, and tensions in the Middle East and rising crude oil prices. Other factors contributing to the recent price surge include the strengthening economy, the increased capacity and planned new capacity of gas-burning power plants, and concerns about the decline in gas-directed drilling.

Short-term energy outlook: Quarterly projections. Second quarter 1995  

SciTech Connect

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent projections with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the second quarter of 1995 through the fourth quarter of 1996. Values for the first quarter of 1995, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data, compiled into the second quarter 1995 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service.

Status and evaluation of hybrid electric vehicle batteries for short term applications. Final report  

SciTech Connect

The objective of this task is to compile information regarding batteries which could be use for electric cars or hybrid vehicles in the short term. More specifically, this study applies lead-acid batteries and nickel-cadmium battery technologies which are more developed than the advanced batteries which are presently being investigated under USABC contracts and therefore more accessible in production efficiency and economies of scale. Moreover, the development of these batteries has advanced the state-of-the-art not only in terms of performance and energy density but also in cost reduction. The survey of lead-acid battery development took the biggest part of the effort, since they are considered more apt to be used in the short-term. Companies pursuing the advancement of lead-acid batteries were not necessarily the major automobile battery manufacturers. Innovation is found more in small or new companies. Other battery systems for short-term are discussed in the last part of this report. We will review the various technologies investigated, their status and prognosis for success in the short term.

Short-Term Energy Outlook: Quarterly projections. Fourth quarter 1993  

SciTech Connect

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the fourth quarter of 1993 through the fourth quarter of 1994. Values for the third quarter of 1993, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data are EIA data published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications.

Comparisons of Short Term Load Forecasting using Artificial Neural Network and Regression Method  

E-Print Network (OSTI)

In power systems the next day’s power generation must be scheduled every day, day ahead short-term load forecasting (STLF) is a necessary daily task for power dispatch. Its accuracy affects the economic operation and reliability of the system greatly. Under prediction of STLF leads to insufficient reserve capacity preparation and in turn, increases the operating cost by using expensive peaking units. On the other hand, over prediction of STLF leads to the unnecessarily large reserve capacity, which is also related to high operating cost. the research work in this area is still a challenge to the electrical engineering scholars because of its high complexity. How to estimate the future load with the historical data has remained a difficulty up to now, especially for the load forecasting of holidays, days with extreme weather and other anomalous days. With the recent development of new mathematical, data mining and artificial intelligence tools, it is potentially possible to improve the forecasting result. This paper presents a new neural network based approach for short-term load forecasting that uses the most correlated weather data for training, validating and testing the neural network. Correlation analysis of weather data determines the input parameters of the neural networks. And its results compare to regression method.

Short-term energy outlook: Quarterly projections, second quarter 1997  

Science Conference Proceedings (OSTI)

The Energy Information Administration (EIA) prepares quarterly short-term energy supply, demand, and price projections for publication in January, April, July, and October in the Outlook. The forecast period for this issue of the Outlook extends from the second quarter of 1997 through the fourth quarter of 1998. Values for the first quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the second quarter 1997 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the Short-Term Integrated Forecasting System (STIFS). 34 figs., 19 tabs.

Efficient Tracking for Short-Term Multi-Company Networks  

E-Print Network (OSTI)

Tracking of shipments is an important element of customer service in the transportation industry; and essential for logistics services as merge-in-transit. However, contemporary tracking systems are designed for use within a single company, and are thus invariably inadequate for multi-company environments. The single company focus has led to a reduced span of monitoring and a diluted accessibility of information due to proprietary tracking codes and information architectures centred on the tracking service provider. This paper presents a novel forwarder-independent approach for solving the difficulties of tracking in multi-company supply networks. The research argues that the proposed tracking approach is superior to contemporary approaches for material flow tracking in short-term multi-company distribution networks.

Prices are expected to be less variable unless unusually hot weather in late summer results in gas being diverted from storage to meet the added cooling demand, or colder-than-normal weather for October results in an unexpected drawdown of storage stocks. Overall in 2002, wellhead prices are expected to average about $2.73 per MMBtu compared with $4.00 in 2001. Prices during the upcoming heating season (November through March), assuming normal weather, are expected to average close to $3.12 per MMBtu, which is about $0.75 higher than last winter's price but only about 10-15 percent higher than current prices.

Models for Short-Term Production Planning of Cogeneration Plants  

E-Print Network (OSTI)

The short-term production planning problem for a district heating system is a well-known but difficult optimization problem. In a district heating plant several types of energy producing units are used, the most important being the cogeneration unit, which produces both heat and electricity. The net electricity is sold at the electricity market. Most plants also have a heat water storage. Finding the optimal production of both heat and electricity and the optimal use of the heat water storage is a challenging mixed optimization problem. The production planning may be divided into two sub-problems. The unit commitment problem determines which units should be on or off and in which different mode the unit should run. The economic dispatch problem finds the optimal production plan given the units on and running modes. In this paper we formulate a new approach for the mathematical modeling of the economic dispatch problem. The model objective function is nonlinear, with nonlinear constrain...

Implications of Wide-Area Geographic Diversity for Short- Term Variability of Solar Power  

SciTech Connect

Worldwide interest in the deployment of photovoltaic generation (PV) is rapidly increasing. Operating experience with large PV plants, however, demonstrates that large, rapid changes in the output of PV plants are possible. Early studies of PV grid impacts suggested that short-term variability could be a potential limiting factor in deploying PV. Many of these early studies, however, lacked high-quality data from multiple sites to assess the costs and impacts of increasing PV penetration. As is well known for wind, accounting for the potential for geographic diversity can significantly reduce the magnitude of extreme changes in aggregated PV output, the resources required to accommodate that variability, and the potential costs of managing variability. We use measured 1-min solar insolation for 23 time-synchronized sites in the Southern Great Plains network of the Atmospheric Radiation Measurement program and wind speed data from 10 sites in the same network to characterize the variability of PV with different degrees of geographic diversity and to compare the variability of PV to the variability of similarly sited wind. The relative aggregate variability of PV plants sited in a dense 10 x 10 array with 20 km spacing is six times less than the variability of a single site for variability on time scales less than 15-min. We find in our analysis of wind and PV plants similarly sited in a 5 x 5 grid with 50 km spacing that the variability of PV is only slightly more than the variability of wind on time scales of 5-15 min. Over shorter and longer time scales the level of variability is nearly identical. Finally, we use a simple approximation method to estimate the cost of carrying additional reserves to manage sub-hourly variability. We conclude that the costs of managing the short-term variability of PV are dramatically reduced by geographic diversity and are not substantially different from the costs for managing the short-term variability of similarly sited wind in this region.

Economic Evaluation of Short-Term Wind Power Forecasts in ERCOT: Preliminary Results; Preprint  

DOE Green Energy (OSTI)

Historically, a number of wind energy integration studies have investigated the value of using day-ahead wind power forecasts for grid operational decisions. These studies have shown that there could be large cost savings gained by grid operators implementing the forecasts in their system operations. To date, none of these studies have investigated the value of shorter-term (0 to 6-hour-ahead) wind power forecasts. In 2010, the Department of Energy and National Oceanic and Atmospheric Administration partnered to fund improvements in short-term wind forecasts and to determine the economic value of these improvements to grid operators, hereafter referred to as the Wind Forecasting Improvement Project (WFIP). In this work, we discuss the preliminary results of the economic benefit analysis portion of the WFIP for the Electric Reliability Council of Texas. The improvements seen in the wind forecasts are examined, then the economic results of a production cost model simulation are analyzed.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

average $2.83 per MMBtu in 2002 compared with about $4.00 last year (Short-Term Energy Outlook, June 2002). Average wellhead prices have increased by nearly 50 percent from $2.09 per MMBtu in February to an estimated $3.11 per MMBtu in May. Spot prices at the Henry Hub have also increased, rising more than $1.00 per MMBtu since early February. It is atypical to see higher spot gas prices in the cooling season than during the heating season, particularly when working gas in underground storage is at high levels, as it has been for the past several months. As of the end of May, working gas levels were more than 20 percent above the previous 5-year average for that month. Moreover, gas-directed drilling, while down sharply from summer 2001 levels, is still quite strong from a historical perspective. The gas rig count as of May 31 was up 22 percent from the recent low of 591 for the week ending April 5.

4.41 per MMBtu in December 2003, although spot prices are expected to average $5.38 (Short-Term Energy Outlook, December 2003). The average wellhead price is expected to increase moderately to $4.56 during the first three months of 2004. Natural gas prices were lower in November than previously expected but forward price expectations remain sensitive to weather conditions. Prices increased rapidly in futures trading in early December as some cold weather moved into the Eastern United States and reported withdrawals from gas storage were slightly larger than expected. Spot prices above $5 per MMBtu remain likely over the next few months if normal (or colder) weather prevails, especially with oil prices remaining at relatively high levels. Natural gas storage levels are still above average and hold the potential to push prices back down if warm temperatures and weak heating demand materialize later in the winter, just as upward spikes remain a strong possibility if the weather turns cold.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

about $3.49 per MMBtu through December 2002 and then increase to $3.76 in January 2003, the peak demand month of the heating season (Short-Term Energy Outlook, released November 7, 2002). Natural gas prices were higher than expected in October as storms in the Gulf of Mexico in late September temporarily shut in some gas production, causing spot prices at the Henry Hub and elsewhere to rise above $4.00 per million Btu for most of October. In addition, early winter-like temperatures, particularly in the Midwest and Northeast, increased demand for natural gas, placing upward pressure on gas prices. Overall in 2002, wellhead prices are expected to average about $2.84 per MMBtu compared with $4.00 in 2001. Prices during the heating season (November through March), assuming normal weather, are expected to average $3.56 per MMBtu, which is about $1.20 higher than last winter's price. Prices to residential customers during the heating season are expected to average $7.81 per MMBtu compared with $7.14 last winter. In 2003, wellhead prices are projected to average $3.28 per MMBtu, or about $0.44 per MMBtu more than in 2002, owing to expectations of increasing economic growth, little or no change in the annual average crude oil price for 2003, and lower storage levels for most of 2003 compared with 2002 levels.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

7 per MMBtu during the last 3 months of 2003 and increase to $4.32 in January 2004 (Short-Term Energy Outlook, October 2003). Prices have fallen somewhat from the unusually high levels that prevailed in the first half of the year and most of July, as mild summer weather and reduced industrial demand allowed record storage refill rates. As of October 3, 2003, working gas levels were only 1 percent below the 5-year average and, barring any disruptions, are on target to reach 3 Tcf by the end of October. With the improved storage situation, wellhead prices during the upcoming heating season (November through March), assuming normal weather, are expected to be about 13 percent less than last winter ($4.17 vs. $4.68 per MMBtu). But prices in the residential sector are projected to be about 9 percent higher than last winter, as the recent decline in wellhead prices is too recent and insufficient to offset the impact of the substantial spring-summer increase in wellhead prices on residential prices. Overall in 2003, wellhead prices are expected to average $4.75 per MMBtu, which is nearly $2 more than the 2002 annual average and the largest year-to-year increase on record. For 2004, wellhead prices are projected to drop by nearly $0.90 per MMBtu, or about 20 percent, to $3.86 per MMBtu as the overall supply situation improves.

in September and range between $4.37 and $4.58 per MMBtu in the last 3 months of 2003 (Short-Term Energy Outlook, September 2003). Spot prices at the Henry Hub have fallen somewhat from the unusually high levels that prevailed in the first half of the year and most of July, as mild summer weather in many areas of the country has reduced cooling demand and allowed record storage refill rates. As of September 5, working gas levels were only 5.5 percent below the 5-year average and, barring any disruptions, are on target to reach 3 Tcf by the end of October. However, gas prices remain high-wellhead prices this summer are estimated to be 60 to 70 percent higher than levels last summer. Overall in 2003, wellhead prices are expected to average $4.84 per MMBtu, which is nearly $2 more than the 2002 annual average and the largest year-to-year increase on record. For 2004, assuming normal weather, wellhead prices are projected to drop by about $1 per MMBtu, or almost 20 percent, to $3.89 per MMBtu, as the overall supply situation improves.

137

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

5.57 per MMBtu in January 2004 and $5.40 in February, and then decrease to $4.77 in March as the heating season winds down (Short-Term Energy Outlook, January 2004). Spot prices were quite variable in December, with prices at the Henry Hub starting the month at around $5.00 per MMBtu, spiking to roughly $7.00 in the middle of the month, then falling to $5.50 toward the end of the month as warmer-than-normal weather eased demand. Spot prices will likely remain well above $5.00 over the next few months if normal or colder weather prevails, especially with oil prices remaining at relatively high levels. (Oil prices this winter are expected to average $31.35 per barrel (19 cents higher than last winter's average), or 5.41 per MMBtu.) Natural gas storage levels were 8 percent above average as of January 2, which could place downward pressure on prices if warm temperatures and weak heating demand occur later this winter, just as rising prices are possible if the weather becomes colder. Overall in 2004, natural gas wellhead prices are expected to average $4.73 per MMBtu, while spot prices will average nearly $5.00. In 2005, natural gas spot prices are projected to fall to an average of $4.83 per MMBtu under the assumption that domestic and imported supply can continue to grow by about 1-1.5 percent per year.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

Now that the heating season has ended, natural gas wellhead prices have fallen from the exceptionally high levels seen in February and early March. Nevertheless, they still remain historically and unseasonably high, hovering around $5.00 per MMBtu. EIA projects that natural gas wellhead prices will remain above $5.00 per MMBtu in April and then decrease to $4.36 in May and $4.26 in June (Short-Term Energy Outlook, April 2003). Wellhead prices for the 2002-2003 heating season (November through March) averaged $4.44 per MMBtu, or $2.08 more than last winter's price. Overall in 2003, wellhead prices are projected to increase about $1.53 per MMBtu over the 2002 level to $4.40 per MMBtu. This projection is based on the expectation of lower volumes of natural gas in underground storage compared with last year and continued increases in demand over 2002 levels. Cold temperatures this past winter led to a record drawdown of storage stocks. By the end of March, estimated working gas stocks were 676 Bcf (prior estimates were 696 Bcf), which is the lowest end-of-March level in EIA records and 44 percent below the previous 5-year average. In 2004, continued tightness of domestic natural gas supply and high demand levels are expected to keep the average wellhead price near the 2003 level.

139

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

4.20 per MMBtu through January 2003 and then increase to $4.61 in February and $4.23 in March (Short-Term Energy Outlook, released January 8, 2003). Wellhead prices for the overall heating season (November through March), assuming normal weather, are expected to average about $4.10 per MMBtu, or $1.74 more than last winter's levels, while prices to residential customers are expected to average $8.51 per MMBtu compared with $7.14 last winter. Natural gas prices were higher than expected in November and December as below-normal temperatures throughout much of the nation increased heating demand, placing upward pressure on gas prices. Spot prices at the Henry Hub climbed above $5.00 per MMBtu in the second week of December and stayed near or above this threshold through the end of the month. Overall in 2002, wellhead prices are expected to average $2.90 per MMBtu compared with $4.00 in 2001. In 2003, average wellhead prices are projected to increase about $1.00 per MMBtu over the 2002 level to $3.90 per MMBtu, owing to expectations of higher demand levels than in 2002 and lower storage levels for most of the year compared with 2002 levels.

Gasoline and Diesel Fuel Update (EIA)

the rest of the winter and the first part of spring, with prices averaging $5.19 per MMBtu through March and $4.58 in April (Short-Term Energy Outlook, February 2004). Wellhead prices for the current heating season (November 2003 through March 2004) are expected to average $4.99 per MMBtu, or about 7 percent higher than last winter's level. Spot prices at the Henry Hub averaged $5.90 per MMBtu in January as cold temperatures (6 percent colder than normal nationally and 19 percent colder than normal in the Northeast) kept natural gas prices and heating demand high. Despite the severe weather, natural gas storage stocks were 3 percent above average as of January 30 and spot prices in early February have moved down somewhat. Overall in 2004, spot prices are expected to average about $4.90 per MMBtu and wellhead prices are expected to average $4.63 per MMBtu, declining moderately from the 2003 levels. In 2005, natural gas spot prices are projected to average about $5.00 per MMBtu, under the assumption that domestic and imported supply can continue to grow by about 1 percent per year.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

this summer and continue at elevated levels through the rest of 2003 (Short-Term Energy Outlook, June 2003). Natural gas wellhead prices are expected to average $5.40 per MMBtu in June and remain above $5.13 through December 2003. Spot prices at the Henry Hub have stayed well above $5.00 per MMBtu on a monthly basis since the beginning of the year and have been above $6.00 for the first 10 days of June. The low level of underground storage is the principal reason for these unusually high prices. As of June 6, 2003, working gas stocks were 1,324 Bcf, which is about 35 percent below year-earlier levels and 25 percent below the 5-year average. Natural gas prices are likely to stay high as long as above-normal storage injection demand competes with industrial and power sector demand for gas. Overall in 2003, wellhead prices are projected to increase about $2.33 per MMBtu (the largest U.S. annual wellhead price increase on record) over the 2002 level to a record annual high of about $5.20 per MMBtu. For 2004, prices are projected to ease only moderately, as supplies are expected to remain tight.

range from $2.91 to $3.19 per MMBtu through December 2002 and then increase to $3.53 in January 2003, the peak demand month of the heating season (Short-Term Energy Outlook, October 2002). Natural gas prices climbed sharply in late September as hurricanes Isidore and Lili caused production shut downs in the Gulf of Mexico. However, this price surge is expected to be short-lived, unless the weather in October is unusually cold or if additional storm activity in the Gulf curbs production further. Overall in 2002, wellhead prices are expected to average about $2.76 per MMBtu compared with $4.00 in 2001. Prices during the upcoming heating season (November through March), assuming normal weather, are expected to average $3.32 per MMBtu, which is about $0.96 higher than last winter's price. Prices to residential customers during the heating season are expected to average $7.55 per MMBtu compared with $7.14 last winter.

143

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

prices will remain relatively high during the storage refill season (April through October) and the rest of 2004. Wellhead prices are expected to average $4.87 per MMBtu in April and May, $4.71 from June through October, and $5.12 for November and December (Short-Term Energy Outlook, April 2004). Spot prices during the storage refill months will likely average $5.23 per MMBtu, virtually the same as the average price ($5.22) this past heating season. Overall in 2004, spot prices are expected to average $5.31 per MMBtu, slightly less than the 2003 price ($5.35), while wellhead prices will average about $4.90. In 2005, natural gas spot prices will likely average about $5.25 per MMBtu, under the assumption that domestic supply can continue to grow by about 1 percent per year. Total available supply (including imports and storage inventories) is expected to increase to 22.31 Tcf in 2004 compared with 21.78 Tcf in 2003. Storage stocks at the end of the traditional heating season (March 31) were about 6 percent less than the 5-year average but nearly 50 percent more than year-earlier levels.

Short-term energy outlook, quarterly projections, first quarter 1998  

Science Conference Proceedings (OSTI)

The forecast period for this issue of the Outlook extends from the first quarter of 1998 through the fourth quarter of 1999. Values for the fourth quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the first quarter 1998 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are adjusted by EIA to reflect EIA assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 24 figs., 19 tabs.

An Empirical Analysis of Analysts' Target Prices: Short Term . . .  

E-Print Network (OSTI)

Using a large database of analysts' target prices, we examine short-term market reactions to target price announcements and long-term co-movement of target and stock prices. We find a significant market reaction to the information contained in analysts' target prices, both unconditional and conditional on contemporaneously issued stock recommendations and earnings forecast revisions. For example, the spread in average announcement day abnormal returns between positive and negative target price revisions is as high as 7 percent. We also find that stock recommendations and earnings forecast revisions are informative controlling for the information in target prices. Using a cointegration approach, we explore the long-term behavior of market and target prices and estimate the system's long-term equilibrium. In this equilibrium a typical firm's one-year ahead target price is 22 percent higher than its current market price. Finally, while market prices react to the information conveyed in analysts' reports, we show that any subsequent corrections towards the long-term equilibrium are, in effect, done by analysts alone.

Evaluation of a short-term residential building test method  

SciTech Connect

The purpose of this project is to evaluate the effectiveness of an energy performance analysis methodology developed by the Solar Energy Research Institute (SERI). The methodology (STEM/PSTAR) uses data collected from short-term tests conducted over a 3-day period as inputs to a model for predicting long-term performance. Under subcontract to GEOMET, SERI performed the tests on GEOMET's two research houses in Gaithersburg, Maryland, and in a blind test, predicted the heating load and fuel use for a historical period for which detailed monitoring data were available. The predicted heating load and fuel usage were compared to the actual heating load and fuel usage for the period. STEM/PSTAR predictions of heating load fuel usage agreed quite well with the measured data. The predicted heating load using the STEM/PSTAR methodology was within 1 percent of the measured heating load. STEM/PSTAR tended to overpredict fuel usage by about 10 percent. Potential applications of the method include the evaluation of demand-site management technologies, new home energy performance evaluation and heating system performance evaluation.

Application of Ensemble Sensitivity Analysis to Observation Targeting for Short-term Wind Speed Forecasting  

Science Conference Proceedings (OSTI)

The operators of electrical grids, sometimes referred to as Balancing Authorities (BA), typically make critical decisions on how to most reliably and economically balance electrical load and generation in time frames ranging from a few minutes to six hours ahead. At higher levels of wind power generation, there is an increasing need to improve the accuracy of 0- to 6-hour ahead wind power forecasts. Forecasts on this time scale have typically been strongly dependent on short-term trends indicated by the time series of power production and meteorological data from a wind farm. Additional input information is often available from the output of Numerical Weather Prediction (NWP) models and occasionally from off-site meteorological towers in the region surrounding the wind generation facility. A widely proposed approach to improve short-term forecasts is the deployment of off-site meteorological towers at locations upstream from the wind generation facility in order to sense approaching wind perturbations. While conceptually appealing, it turns out that, in practice, it is often very difficult to derive significant benefit in forecast performance from this approach. The difficulty is rooted in the fact that the type, scale, and amplitude of the processes controlling wind variability at a site change from day to day if not from hour to hour. Thus, a location that provides some useful forecast information for one time may not be a useful predictor a few hours later. Indeed, some processes that cause significant changes in wind power production operate predominantly in the vertical direction and thus cannot be monitored by employing a network of sensors at off-site locations. Hence, it is very challenging to determine the type of sensors and deployment locations to get the most benefit for a specific short-term forecast application. Two tools recently developed in the meteorological research community have the potential to help determine the locations and parameters to measure in order to get the maximum positive impact on forecast performance for a particular site and short-term look-ahead period. Both tools rely on the use of NWP models to assess the sensitivity of a forecast for a particular location to measurements made at a prior time (i.e. the look-ahead period) at points surrounding the target location. The fundamental hypothesis is that points and variables with high sensitivity are good candidates for measurements since information at those points are likely to have the most impact on the forecast for the desired parameter, location and look-ahead period. One approach is called the adjoint method (Errico and Vukicevic, 1992; Errico, 1997) and the other newer approach is known as Ensemble Sensitivity Analysis (ESA; Ancell and Hakim 2007; Torn and Hakim 2008). Both approaches have been tested on large-scale atmospheric prediction problems (e.g. forecasting pressure or precipitation over a relatively large region 24 hours ahead) but neither has been applied to mesoscale space-time scales of winds or any other variables near the surface of the earth. A number of factors suggest that ESA is better suited for short-term wind forecasting applications. One of the most significant advantages of this approach is that it is not necessary to linearize the mathematical representation of the processes in the underlying atmospheric model as required by the adjoint approach. Such a linearization may be especially problematic for the application of short-term forecasting of boundary layer winds in complex terrain since non-linear shifts in the structure of boundary layer due to atmospheric stability changes are a critical part of the wind power production forecast problem. The specific objective of work described in this paper is to test the ESA as a tool to identify measurement locations and variables that have the greatest positive impact on the accuracy of wind forecasts in the 0- to 6-hour look-ahead periods for the wind generation area of California's Tehachapi Pass during the warm (high generation) season.

Long vs. short-term energy storage:sensitivity analysis.  

DOE Green Energy (OSTI)

This report extends earlier work to characterize long-duration and short-duration energy storage technologies, primarily on the basis of life-cycle cost, and to investigate sensitivities to various input assumptions. Another technology--asymmetric lead-carbon capacitors--has also been added. Energy storage technologies are examined for three application categories--bulk energy storage, distributed generation, and power quality--with significant variations in discharge time and storage capacity. Sensitivity analyses include cost of electricity and natural gas, and system life, which impacts replacement costs and capital carrying charges. Results are presented in terms of annual cost, $/kW-yr. A major variable affecting system cost is hours of storage available for discharge.

Newporter Apartments: Deep Energy Retrofit Short-Term Results  

SciTech Connect

This project demonstrates a path to meet the goal of the Building America program to reduce home energy use by 30% in multi-family buildings. The project demonstrates cost effective energy savings targets as well as improved comfort and indoor environmental quality (IEQ) associated with deep energy retrofits by a large public housing authority as part of a larger rehabilitation effort. The project focuses on a typical 1960's vintage low-rise multi-family apartment community (120 units in three buildings).

Centre de Referència en Economia Analítica Barcelona Economics Working Paper Series Working Paper nº 185 Why Do Emerging Economies Borrow Short Term?  

E-Print Network (OSTI)

Barcelona Economics WP nº 185 We argue that emerging economies borrow short term due to the high risk premium charged by international capital markets on long-term debt. First, we present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders. By issuing long-term debt, the government lowers the probability of a liquidity crisis, transferring risk to bondholders. In equilibrium, this risk is reflected in a higher risk premium and borrowing cost. Therefore, the government faces a trade-off between safer long-term borrowing and cheaper short-term debt. Second, we construct a new database of sovereign bond prices and issuance. We show that emerging economies pay a positive term premium (a higher risk premium on long-term bonds than on short-term bonds). During crises, the term premium increases, with issuance shifting toward shorter maturities. This suggests that changes in

Short-Term Carbon Dioxide Exchange and Environmental Factors in a Boreal Fen  

E-Print Network (OSTI)

Introduction Northern peatlands are important contributors to the global carbon cycle. In cold and moist climatic conditions, boreal peatlands have sequestered large amounts of atmospheric carbon during the past few thousand years (GORHAM 1991). The carbon balance in mires depends on the rates of photosynthesis and respiration which are affected by both the long-term and the short-term variations in environmental factors. So far, more emphasis has been put on the annual carbon balance of mires, and short-term dynamics have received less attention. However, a relationship between the carbon dioxide and methane cycling has been proposed as newly photosynthesized carbon provides substrates for methanogenesis substrates and promotes methane emissions (WHITING & CHANTON 1993). To analyze the connection between green plant photosynthesis and methane emissions, we need to analyze the short-term dynamics of carbon dioxide exchange. Consequently, we use earlier data (ALM et al. 1997) to study

Short-term effects of Gamma Ray Bursts on oceanic photosynthesis  

E-Print Network (OSTI)

We continue our previous work on the potential short-term influence of a gamma ray bursts on Earth's biosphere, focusing on the only important short-term effect on life: the ultraviolet flash which occurs as a result of the retransmission of the {\\gamma} radiation through the atmosphere. Thus, in this work we calculate the ultraviolet irradiances penetrating the first hundred meters of the water column, for Jerlov's ocean water types I, II and III. Then we estimate the UV flash potential for photosynthesis inhibition, showing that it can be important in a considerable part of the water column with light enough for photosynthesis to be done, the so called photic zone.

Short-term energy outlook. Quarterly projections, 2nd quarter 1994  

SciTech Connect

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. The forecast period for this issue of the Outlook extends from the second quarter of 1994 through the fourth quarter of 1995. Values for the first quarter of 1994, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available. The historical energy data, compiled into the second quarter 1994 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The cases are produced using the STIFS. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. The EIA model is available on computer tape from the National Technical Information Service.

www.inescc.pt 1 Short Term Load Forecasting Using Gaussian Process Models  

E-Print Network (OSTI)

Abstract — The electrical deregulated market increases the need for short-term load forecast algorithms in order to assist electrical utilities in activities such as planning, operating and controlling electric energy systems. Methodologies based on regression methods have been widely used with satisfactory results. However, this type of approach has some shortcomings. This paper proposes a short-term load forecast methodology applied to distribution systems, based on Gaussian Process models. This methodology establishes an interesting and valuable approach to short-term forecasting applied to the electrical sector. The results obtained are in accordance with the best values of expected errors for these types of methodologies. A careful study of the input variables (regressors) was made, from the point of view of contiguous values, in order to include the strictly necessary instances of endogenous variables. Regressors representing the trend of consumption, at homologous time intervals in the past, were also included in the input vector. The proposed approach was tested on real-load from three medium-sized supply electrical distribution substations located in the center of Portugal. To test the performance of the model in different load situations, the case study includes three different electrical distribution substations representative of typical load consuming patterns,

Sullivan, and Joseph H. Eto Pagination 120 Date Published 01/2012 Publisher LBNL City Berkeley Keywords consortium for electric reliability technology solutions (certs), electricity markets and policy group, energy analysis and environmental impacts department Abstract Several recent demonstrations and pilots have shown that air conditioner (AC) electric loads can be controlled during the summer cooling season to provide ancillary services and improve the stability and reliability of the electricity grid. A key issue for integration of air conditioner load control into grid operations is how to accurately measure shorter-term (e.g., ten's of minutes to a couple of hours) demand reductions from AC load curtailments for operations and settlement. This report presents a framework for assessing the accuracy of shorter-term AC load control demand reduction measurements. It also compares the accuracy of various alternatives for measuring AC reductions - including methods that rely on regression analysis, load matching and control groups - using feeder data, household data and AC end-use data. A practical approach is recommended for settlement that relies on set of tables, updated annually, with pre-calculated load reduction estimates. The tables allow users to look up the demand reduction per device based on the daily maximum temperature, geographic region and hour of day and simplify the settlement process.

Interpretation of a Short-Term Anomaly in the Gravitational Microlensing Event MOA-2012-BLG-486  

E-Print Network (OSTI)

A planetary microlensing signal is generally characterized by a short-term perturbation to the standard single lensing light curve. A subset of binary-source events can produce perturbations that mimic planetary signals, thereby introducing an ambiguity between the planetary and binary-source interpretations. In this paper, we present analysis of the microlensing event MOA-2012-BLG-486, for which the light curve exhibits a short-lived perturbation. Routine modeling not considering data taken in different passbands yields a best-fit planetary model that is slightly preferred over the best-fit binary-source model. However, when allowed for a change in the color during the perturbation, we find that the binary-source model yields a significantly better fit and thus the degeneracy is clearly resolved. This event not only signifies the importance of considering various interpretations of short-term anomalies, but also demonstrates the importance of multi-band data for checking the possibility of false-positive pla...

(Short-term assays for detecting environmental mutagens, carcinogens, and teratogens)  

SciTech Connect

The traveler attended the Second Southeast Asian Workshop on Short-Term Assays for detecting Environmental Mutagens, Carcinogens, and Teratogens and presented a lecture on his work with transgenic mice. The work shop was sponsored by the Thai National Cancer Institute and was designed to acquaint scientists in Thailand and other Southeast Asian countries with the principles and state-of-the-art methods for detecting genotoxic agents. Many of the prominent scientists lecturing at the workshop, as well as several of the participants, expressed strong support for the short-term in vivo genotoxicity assays in transgenic mice that are currently under development in the traveler's laboratory in the Biology Division at ORNL. The traveler also participated in a panel discussion sponsored by the Thai Science and Technology Development Board (STDP) on the development of molecular biology programs at the universities in Thailand. After two weeks in Thailand, the traveler flew to the Philippines with several other American scientists to spend two days visiting the University of the Philippines, meeting with students and faculty, and presenting a lecture on his work with transgenic mice.

EVALUATING SHORT-TERM CLIMATE VARIABILITY IN THE LATE HOLOCENE OF THE NORTHERN GREAT PLAINS  

Science Conference Proceedings (OSTI)

This literature study investigated methods and areas to deduce climate change and climate patterns, looking for short-term cycle phenomena and the means to interpret them. Many groups are actively engaged in intensive climate-related research. Ongoing research might be (overly) simplified into three categories: (1) historic data on weather that can be used for trend analysis and modeling; (2) detailed geological, biological (subfossil), and analytical (geochemical, radiocarbon, etc.) studies covering the last 10,000 years (about since last glaciation); and (3) geological, paleontological, and analytical (geochemical, radiometric, etc.) studies over millions of years. Of importance is our ultimate ability to join these various lines of inquiry into an effective means of interpretation. At this point, the process of integration is fraught with methodological troubles and misconceptions about what each group can contribute. This project has met its goals to the extent that it provided an opportunity to study resource materials and consider options for future effort toward the goal of understanding the natural climate variation that has shaped our current civilization. A further outcome of this project is a proposed methodology based on ''climate sections'' that provides spatial and temporal correlation within a region. The method would integrate cultural and climate data to establish the climate history of a region with increasing accuracy with progressive study and scientific advancement (e. g., better integration of regional and global models). The goal of this project is to better understand natural climatic variations in the recent past (last 5000 years). The information generated by this work is intended to provide better context within which to examine global climate change. The ongoing project will help to establish a basis upon which to interpret late Holocene short-term climate variability as evidenced in various studies in the northern Great Plains, northern hemisphere, and elsewhere. Finally these data can be integrated into a history of climate change and predictive climate models. This is not a small undertaking. The goals of researchers and the methods used vary considerably. The primary task of this project was literature research to (1) evaluate existing methodologies used in geologic climate change studies and evidence for short-term cycles produced by these methodologies and (2) evaluate late Holocene climate patterns and their interpretations.

Winchester/Camberley Homes New Construction Test House Design, Construction, and Short-Term Testing in a Mixed-Humid Climate  

SciTech Connect

The NAHB Research Center partnered with production builder Winchester/Camberley Homes to build a DOE Building America New Construction Test House (NCTH). This single family, detached house, located in the mixed-humid climate zone of Silver Spring, MD, was completed in June 2011. The primary goal for this house was to improve energy efficiency by 30% over the Building America B10 benchmark by developing and implementing an optimized energy solutions package design that could be cost effectively and reliably constructed on a production basis using quality management practices. The intent of this report is to outline the features of this house, discuss the implementation of the energy efficient design, and report on short-term testing results. During the interactive design process of this project, numerous iterations of the framing, air sealing, insulation, and space conditioning systems were evaluated for energy performance, cost, and practical implementation. The final design featured numerous advanced framing techniques, high levels of insulation, and the HVAC system entirely within conditioned space. Short-term testing confirmed a very tight thermal envelope and efficient and effective heating and cooling. In addition, relevant heating, cooling, humidity, energy, and wall cavity moisture data will be collected and presented in a future long-term report.

Algorithms for Short-Term Production-Planning of Cogeneration Plants  

E-Print Network (OSTI)

A cogeneration plant, feeding its output water into a district-heating network, may include several types of energy producing units. The most important being the Cogeneration unit, which produces both heat and electricity. Most plants also have a Heat water storage. Finding the optimal production of both heat and electricity and the optimal use of the storage is a challenging mixed integer nonlinear optimization problem. The calculations may be divided into two sub-problems. The unit commitment problem is the problem to determine when a unit should be producing (on) or not (off). To solve the economic dispatch problem is to find the optimal production plan given which units are producing in each time interval. Together the solution of these two problems form the solution of the short-term production-planning problem. In this thesis a general approach for the mathematical modeling of a cogeneration plant is presented. The model objective function is nonlinear, with nonlinear constraints....

Short-term Variations in the Galactic Environment of the Sun  

E-Print Network (OSTI)

The galactic environment of the Sun varies over short timescales as the Sun and interstellar clouds travel through space. Small variations in the dynamics, ionization, density, and magnetic field strength of the interstellar medium (ISM) surrounding the Sun yield pronounced changes in the heliosphere. We discuss essential information required to understand short-term variations in the galactic environment of the Sun, including the distribution and radiative transfer properties of nearby ISM, and variations in the boundary conditions of the heliosphere as the Sun traverses clouds. The most predictable transitions are when the Sun emerged from the Local Bubble interior and entered the cluster of local interstellar clouds flowing past the Sun, within the past 140,000 years, and again when the Sun entered the local interstellar cloud now surrounding and inside of the solar system, sometime during the past 44,000 years.

Freeway Short-Term Traffic Flow Forecasting by Considering Traffic Volatility Dynamics and Missing Data Situations  

E-Print Network (OSTI)

Short-term traffic flow forecasting is a critical function in advanced traffic management systems (ATMS) and advanced traveler information systems (ATIS). Accurate forecasting results are useful to indicate future traffic conditions and assist traffic managers in seeking solutions to congestion problems on urban freeways and surface streets. There is new research interest in short-term traffic flow forecasting due to recent developments in ITS technologies. Previous research involves technologies in multiple areas, and a significant number of forecasting methods exist in literature. However, forecasting reliability is not properly addressed in existing studies. Most forecasting methods only focus on the expected value of traffic flow, assuming constant variance when perform forecasting. This method does not consider the volatility nature of traffic flow data. This paper demonstrated that the variance part of traffic flow data is not constant, and dependency exists. A volatility model studies the dependency among the variance part of traffic flow data and provides a prediction range to indicate the reliability of traffic flow forecasting. We proposed an ARIMA-GARCH (Autoregressive Integrated Moving Average- AutoRegressive Conditional Heteroskedasticity) model to study the volatile nature of traffic flow data. Another problem of existing studies is that most methods have limited forecasting abilities when there is missing data in historical or current traffic flow data. We developed a General Regression Neural Network(GRNN) based multivariate forecasting method to deal with this issue. This method uses upstream information to predict traffic flow at the studied site. The study results indicate that the ARIMA-GARCH model outperforms other methods in non-missing data situations, while the GRNN model performs better in missing data situations.

Short-Term Power Fluctuation of Wind Turbines: Analyzing Data from the German 250-MW Measurement Program from the Ancillary Services Viewpoint  

SciTech Connect

Short-term power fluctuations from wind farms may affect interconnected-grid operating costs and stability. With the increasing availability of wind power worldwide, this has become a concern for some utilities. Under electric industry restructuring in the United States, the impact of these fluctuations will be evaluated by examining provisions and costs of ancillary services for wind power. However, the magnitude of the impact and the effect of aggregation of multiple turbines are not well quantified due to a lack of actual wind farm power data. This paper analyzes individual turbine and aggregate power output data from the German ''250-MW Wind'' data project. Electric system load following and regulation impacts are examined as a function of the number of turbines and turbine spacing in order to quantify the impacts of aggregation. The results show a significant decrease in the relative system regulation burden with increasing number of turbines, even if the turbines are in close proximity.

Short-Term Energy Monitoring (STEM): Application of the PSTAR method to a residence in Fredericksburg, Virginia  

DOE Green Energy (OSTI)

This report describes a project to assess the thermal quality of a residential building based on short-term tests during which a small number of data channels are measured. The project is called Short- Term Energy Monitoring (STEM). Analysis of the data provides extrapolation to long-term performance. The test protocol and analysis are based on a unified method for building simulations and short-term testing called Primary and Secondary Terms Analysis and Renormalization (PSTAR). In the PSTAR method, renormalized parameters are introduced for the primary terms such that the renormalized energy balance is best satisfied in the least squares sense; hence, the name PSTAR. The mathematical formulation of PSTAR is detailed in earlier reports. This report describes the short-term tests and data analysis performed using the PSTAR method on a residential building in Fredricksburg, Virginia. The results demonstrate the ability of the PSTAR method to provide a realistically complex thermal model of a building, and determine from short-term tests the statics as well as the dynamics of a building, including solar dynamics. 10 refs., 12 figs., 2 tabs.

Short Term Energy Monitoring: What Does This Information Mean to the Facility Energy Manager?  

E-Print Network (OSTI)

Engineers at the Energy Systems Laboratory at Texas A&M University have completed short term energy metering studies at a complex of offices in northern Texas and several buildings on the Texas A&M University campus during the past 18 months. These studies typically consisted of installing electrical metering at the, whole building level and included sub-metering of selected circuits when possible. Personnel would go through the entire facility ensuring that all lighting, fan, and mechanical systems were active and on. After a period of approximately 10 minutes, a selected areas of the building would be "turned off." This sequence was repeated for all areas of interest in the facility. At the end of the lighting test, air handlers, then chilling and pumping equipment was turned off (if applicable) and a final ten minutes of electrical use data taken. In each of these facilities, lighting system load verification was the primary goal and the data provided a very good accounting for all buildings studied. The northern Texas office buildings in particular, were interested in these data for comparison with a recently hired performance contractor. The A&M study was a follow-up to an earlier lighting study that had been conducted by the campus energy office. Base electrical load data was also determined from these tests. This paper presents results of these studies and suggests that the method is attractive to both contractors and facility energy managers as well.

Daily/Hourly Hydrosystem Operation : How the Columbia River System Responds to Short-Term Needs.  

SciTech Connect

The System Operation Review, being conducted by the Bonneville Power Administration, the US Army Corps of Engineers, and the US Bureau of Reclamation, is analyzing current and potential future operations of the Columbia River System. One goal of the System Operations Review is to develop a new System Operation Strategy. The strategy will be designed to balance the many regionally and nationally important uses of the Columbia River system. Short-term operations address the dynamics that affect the Northwest hydro system and its multiple uses. Demands for electrical power and natural streamflows change constantly and thus are not precisely predictable. Other uses of the hydro system have constantly changing needs, too, many of which can interfere with other uses. Project operators must address various river needs, physical limitations, weather, and streamflow conditions while maintaining the stability of the electric system and keeping your lights on. It takes staffing around the clock to manage the hour-to-hour changes that occur and the challenges that face project operators all the time.

Model documentation of the Short-Term Coal Analysis System. Volume 2. Model description. [SCOAL  

Science Conference Proceedings (OSTI)

This is the second of three volumes of documentation for the Short-Term Coal Analysis System (SCOAL) developed by the Coal Data Analysis and Forecasting Branch, Office of Coal, Nuclear, Electric, and Alternate Fuels. The principal aim of SCOAL is to project on a quarterly basis the likely contribution of each of the 26 major bituminous coal, lignite, and anthracite producing states to total US production. A secondary objective is to estimate a companion demand-side aggregated by region but disaggregated by end-use sector. In its current use, the two sides are operated in tandem, and serve to cross-validate each other by means of tracking market balances. The purposes of this report are to describe the estimation method, results, and performance evaluation criteria that were deemed relevant in assessing the potential predictive performance of SCOAL's statistically fitted relationships and to discuss the pre- and post-estimation considerations that prevailed over the course of mode development. The single equation parameter estimates, associated significance levels, statistical equation performance measures, and general comments regarding SCOAL's supply and demand side equations are presented.

Biological monitoring of oil shale products and effluents using short-term genetic analyses  

DOE Green Energy (OSTI)

The long-term health hazards such as mutagenesis, carcinogenesis, and teratogenesis due to the exposure to crude shale oil, particulate pollutants, and the leachates from raw or spent shale constitute a major concern in the development of shale oil technology. In order to monitor such biological effects, we have applied short-term genetic analyses with the exemplary test materials. The Salmonella/microsomal activation system (Ames assay) was generally applicable but only upon chemical fractionation. The Stedman liquid-liquid extraction procedure or the Sephadex gel filtration (LH-20) technique were effectively utilized. Mutagenicity analyses with various crude oils and product water have revealed biological activity in the basic (aromatic amine fractions) or in the neutral (polyaromatic hydrocarbon fraction) fractions. Extracts and chromatographically isolated materials from raw and spent shale were subjected to mutagenicity studies. Mutagenic activity was noted and correlates with the biological activity of compounds that are either identified or predicted to occur in these materials. Comparison to other energy technologies and overall health hazard of the test materials are discussed.

Summary Short?Term Energy Outlook Supplement: Energy Price Volatility and Forecast Uncertainty 1  

E-Print Network (OSTI)

It is often noted that energy prices are quite volatile, reflecting market participants’ adjustments to new information from physical energy markets and/or markets in energyrelated financial derivatives. Price volatility is an indication of the level of uncertainty, or risk, in the market. This paper describes how markets price risk and how the marketclearing process for risk transfer can be used to generate “price bands ” around observed futures prices for crude oil, natural gas, and other commodities. These bands provide a quantitative measure of uncertainty regarding the range in which markets expect prices to trade. The Energy Information Administration’s (EIA) monthly Short-Term Energy Outlook (STEO) publishes “base case ” projections for a variety of energy prices that go out 12 to 24 months (every January the STEO forecast is extended through December of the following year). EIA has recognized that all price forecasts are highly uncertain and has described the uncertainty by identifying the market factors that may significantly move prices away from their expected paths, such as economic growth, Organization of Petroleum Exporting Countries (OPEC) behavior, geo-political events, and hurricanes.

SHORT-TERM SOLAR FLARE LEVEL PREDICTION USING A BAYESIAN NETWORK APPROACH  

SciTech Connect

A Bayesian network approach for short-term solar flare level prediction has been proposed based on three sequences of photospheric magnetic field parameters extracted from Solar and Heliospheric Observatory/Michelson Doppler Imager longitudinal magnetograms. The magnetic measures, the maximum horizontal gradient, the length of neutral line, and the number of singular points do not have determinate relationships with solar flares, so the solar flare level prediction is considered as an uncertainty reasoning process modeled by the Bayesian network. The qualitative network structure which describes conditional independent relationships among magnetic field parameters and the quantitative conditional probability tables which determine the probabilistic values for each variable are learned from the data set. Seven sequential features-the maximum, the mean, the root mean square, the standard deviation, the shape factor, the crest factor, and the pulse factor-are extracted to reduce the dimensions of the raw sequences. Two Bayesian network models are built using raw sequential data (BN{sub R}) and feature extracted data (BN{sub F}), respectively. The explanations of these models are consistent with physical analyses of experts. The performances of the BN{sub R} and the BN{sub F} appear comparable with other methods. More importantly, the comprehensibility of the Bayesian network models is better than other methods.

ACL Reconstruction with Autologous Hamstring Tendon: Comparison of Short Term Clinical Results  

E-Print Network (OSTI)

Purpose: To compare the short term clinical results of anterior cruciate ligament (ACL) reconstruction with autologous hamstring tendon between Rigid-fix and PINN-ACL Cross Pin for femoral side fixation. Materials and Methods: 127 patients who underwent arthroscopic ACL reconstruction using autologous hamstring tendon and had been followedup for over than one year were enrolled for the present study. Rigid-fix was used in 71 cases (group 1), and PINN-ACL Cross Pin was used in 56 cases (group 2). Clinical and radiological results, operation time, and perioperative complications were compared amongst the two groups. Results: The International Knee Documentation Committee subjective score and Lysholm score were 94 and 95 in group 1 and 87 and 91 in group 2, with no statistical difference (p=0.892, p=0.833), respectively. However, significant difference was observed in one-leg hop test between the two groups (p=0.032). Five cases in group 1 and 40 cases in group 2 were found to be associated with perioperative complications with statistical difference (p<0.0001). Conclusions: There was no resultant difference between the employment of PINN-ACL Cross Pin and Rigid-fix as femoral graft fixation for ACL reconstruction with hamstring tendon. However, PINN-ACL Cross Pin led to complications with extensive operation times. Hence, it needs further improvement of tools for minimization of complications. Key words: Anterior cruciate ligament reconstruction, Hamstring tendon, Rigid-fix, PINN-ACL Cross Pin.

Oxygenate Supply/Demand Balances in the Short-Term Integrated Forecasting Model (Released in the STEO March 1998)  

Reports and Publications (EIA)

The blending of oxygenates, such as fuel ethanol and methyl tertiary butyl ether (MTBE), into motor gasoline has increased dramatically in the last few years because of the oxygenated and reformulated gasoline programs. Because of the significant role oxygenates now have in petroleum product markets, the Short-Term Integrated Forecasting System (STIFS) was revised to include supply and demand balances for fuel ethanol and MTBE. The STIFS model is used for producing forecasts in the Short-Term Energy Outlook. A review of the historical data sources and forecasting methodology for oxygenate production, imports, inventories, and demand is presented in this report.

Model documentation report: Short-term Integrated Forecasting System demand model 1985. [(STIFS)  

DOE Green Energy (OSTI)

The Short-Term Integrated Forecasting System (STIFS) Demand Model consists of a set of energy demand and price models that are used to forecast monthly demand and prices of various energy products up to eight quarters in the future. The STIFS demand model is based on monthly data (unless otherwise noted), but the forecast is published on a quarterly basis. All of the forecasts are presented at the national level, and no regional detail is available. The model discussed in this report is the April 1985 version of the STIFS demand model. The relationships described by this model include: the specification of retail energy prices as a function of input prices, seasonal factors, and other significant variables; and the specification of energy demand by product as a function of price, a measure of economic activity, and other appropriate variables. The STIFS demand model is actually a collection of 18 individual models representing the demand for each type of fuel. The individual fuel models are listed below: motor gasoline; nonutility distillate fuel oil, (a) diesel, (b) nondiesel; nonutility residual fuel oil; jet fuel, kerosene-type and naphtha-type; liquefied petroleum gases; petrochemical feedstocks and ethane; kerosene; road oil and asphalt; still gas; petroleum coke; miscellaneous products; coking coal; electric utility coal; retail and general industry coal; electricity generation; nonutility natural gas; and utility petroleum. The demand estimates produced by these models are used in the STIFS integrating model to produce a full energy balance of energy supply, demand, and stock change. These forecasts are published quarterly in the Outlook. Details of the major changes in the forecasting methodology and an evaluation of previous forecast errors are presented once a year in Volume 2 of the Outlook, the Methodology publication.

Short-Term Monitoring to Diagnose Comfort Problems in a Residence in Central Texas  

E-Print Network (OSTI)

This paper presents results from a project to resolve comfort problems created by high indoor humidity in a 3,400 sq.ft. house in Bryan, Texas. The case study house had been certified by the local utility to meet their energy efficiency standards. However, the resident of the house complained that the house felt too humid although the desired temperature conditions were being maintained. Several HVAC contractors had been previously hired to resolve the problem without success. The field measurements undertaken to diagnose the problem are typical of those that could be undertaken by a house inspector and include an inspection of the construction of the house, short-term monitoring of temperature and humidity, blower door tests and whole-house pressurization tests. To perform the analysis both floors of the house were instrumented with portable data loggers and monitored for a period of two weeks to measure the temperature and relative humidity of the supply, return and ambient conditions. Analysis procedures applied to the house include comparing the measured data against the ASHRAE comfort zone (ASHRAE, 1997) which confirmed adequate zone temperatures with high humidity conditions, and inadequate supply air delivery temperatures for humidity removal. Combined results of the blower door tests and whole-house pressurization tests indicated a potential for leakage through the return air duct. After the recommendations were presented to the homeowner, a new contractor was hired and retrofits applied on the house (i.e., cleaning the cooling coils, enlarging the compressor and relining of the return duct). Measurements were then repeated to determine that the problem had been f ~ e d . This paper describes the case study residence, the measurements used to diagnose the problem, analysis methods, and presents results of the application of the analysis.

Short Term Irradiation Test of Fuel Containing Minor Actinides Using the Experimental Fast Reactor Joyo  

Science Conference Proceedings (OSTI)

A mixed oxide containing minor actinides (MA-MOX) fuel irradiation program is being conducted using the experimental fast rector Joyo of the Japan Atomic Energy Agency to research early thermal behavior of MA-MOX fuel. Two irradiation experiments were conducted as part of the short-term phase of this program in May and August 2006. Six prepared fuel pins included MOX fuel containing 3% or 5% americium (Am-MOX), and MOX fuel containing 2% americium and 2% neptunium (Np/Am-MOX). The first test was conducted with high linear heat rates of approximately 430 W/cm maintained during only 10 minutes. After 10 minutes irradiation test, the test subassembly was transferred to the hot cell facility and an Am-MOX pin and a Np/Am-MOX pin were replaced with dummy pins with neutron dosimeters. The test subassembly loaded with the remaining four fuel pins was re-irradiated in Joyo for 24-hours in August 2006 at nearly the same linear power to obtain re-distribution data on MA-MOX fuel. The linear heat rate for each MA-MOX test fuel pin was calculated using the Monte Carlo calculation code MCNP. The calculated fission rates were compared with the measured data based on the Nd-148 method. The maximum linear heat rate was approximately 444{+-}19 W/cm at the actual reactor power of 119.6 MWt. Post irradiation examination of these pins to confirm the absence of fuel melting and the local concentration under irradiation of NpO{sub 2-x} or AmO{sub 2-x}, in the (U,Pu)0{sub 2-x}, fuel are underway. The test results are expected to reduce uncertainties on the margin in the thermal design for MA-MOX fuel. (authors)

Use of short-term test systems for the prediction of the hazard represented by potential chemical carcinogens  

Science Conference Proceedings (OSTI)

It has been hypothesized that results from short-term bioassays will ultimately provide information that will be useful for human health hazard assessment. Historically, the validity of the short-term tests has been assessed using the framework of the epidemiologic/medical screens. In this context, the results of the carcinogen (long-term) bioassay is generally used as the standard. However, this approach is widely recognized as being biased and, because it employs qualitative data, cannot be used to assist in isolating those compounds which may represent a more significant toxicologic hazard than others. In contrast, the goal of this research is to address the problem of evaluating the utility of the short-term tests for hazard assessment using an alternative method of investigation. Chemicals were selected mostly from the list of carcinogens published by the International Agency for Research on Carcinogens (IARC); a few other chemicals commonly recognized as hazardous were included. Tumorigenicity and mutagenicity data on 52 chemicals were obtained from the Registry of Toxic Effects of Chemical Substances (RTECS) and were analyzed using a relative potency approach. The data were evaluated in a format which allowed for a comparison of the ranking of the mutagenic relative potencies of the compounds (as estimated using short-term data) vs. the ranking of the tumorigenic relative potencies (as estimated from the chronic bioassays). Although this was a preliminary investigation, it offers evidence that the short-term tests systems may be of utility in ranking the hazards represented by chemicals which may contribute to increased carcinogenesis in humans as a result of occupational or environmental exposures. 177 refs., 8 tabs.

PSTAR: Primary and secondary terms analysis and renormalization: A unified approach to building energy simulations and short-term monitoring  

DOE Green Energy (OSTI)

This report presents a unified method of hourly simulation of a building and analysis of performance data. The method is called Primary and Secondary Terms Analysis and Renormalization (PSTAR). In the PSTAR method, renormalized parameters are introduced for the primary terms such that the renormalized energy balance equation is best satisfied in the least squares sense, hence, the name PSTAR. PSTAR allows extraction of building characteristics from short-term tests on a small number of data channels. These can be used for long-term performance prediction (''ratings''), diagnostics, and control of heating, ventilating, and air conditioning systems (HVAC), comparison of design versus actual performance, etc. By combining realistic building models, simple test procedures, and analysis involving linear equations, PSTAR provides a powerful tool for analyzing building energy as well as testing and monitoring. It forms the basis for the Short-Term Energy Monitoring (STEM) project at SERI.

Research on Short-term Load Forecasting of the Thermoelectric Boiler Based on a Dynamic RBF Neural Network  

E-Print Network (OSTI)

As thermal inertia is the key factor for the lag of thermoelectric utility regulation, it becomes very important to forecast its short-term load according to running parameters. In this paper, dynamic radial basis function (RBF) neural network is proposed based on the RBF neural network with the associated parameters of sample deviation and partial sample deviation, which are defined for the purpose of effective judgment of new samples. Also, in order to forecast the load of sample with large deviation, sensitivity coefficients of input layer is given in this paper. To validate this model, an experiment is performed on a thermoelectric plant, and the experimental result indicates that the network can be put into extensive use for short-term load forecasting of thermoelectric utility.

Analysis of the Performance Benefits of Short-Term Energy Storage in Wind-Diesel Hybrid Power Systems  

Science Conference Proceedings (OSTI)

A variety of prototype high penetration wind-diesel hybrid power systems have been implemented with different amounts of energy storage. They range from systems with no energy storage to those with many hours worth of energy storage. There has been little consensus among wind-diesel system developers as to the appropriate role and amount of energy storage in such systems. Some researchers advocate providing only enough storage capacity to supply power during the time it takes the diesel genset to start. Others install large battery banks to allow the diesel(s) to operate at full load and/or to time-shift the availability of wind-generated electricity to match the demand. Prior studies indicate that for high penetration wind-diesel systems, short-term energy storage provides the largest operational and economic benefit. This study uses data collected in Deering, Alaska, a small diesel-powered village, and the hybrid systems modeling software Hybrid2 to determine the optimum amount of short-term storage for a particular high penetration wind-diesel system. These findings were then generalized by determining how wind penetration, turbulence intensity, and load variability affect the value of short term energy storage as measured in terms of fuel savings, total diesel run time, and the number of diesel starts.

Short-Term Test Results: Transitional Housing Energy Efficiency Retrofit in the Hot-Humid Climate  

SciTech Connect

This project evaluates the renovation of a 5,800 ft2, multi-use facility located in St. Petersburg, on the west coast of central Florida, in the hot humid climate. An optimal package of retrofit measures was designed to deliver 30-40% annual energy cost savings for this building with annual utility bills exceeding $16,000 and high base load consumption. Researchers projected energy cost savings for potential retrofit measures based on pre-retrofit findings and disaggregated, weather normalized utility bills as a basis for simulation true-up. A cost-benefit analysis was conducted for the seven retrofit measures implemented; adding attic insulation and sealing soffits, tinting windows, improving whole building air-tightness, upgrading heating and cooling systems and retrofitting the air distribution system, replacing water heating systems, retrofitting lighting, and replacing laundry equipment. The projected energy cost savings for the full retrofit package based on a post-retrofit audit is 35%. The building's architectural characteristics, vintage, and residential and commercial uses presented challenges for both economic projections and retrofit measure construction.

Enhanced Short-Term Wind Power Forecasting and Value to Grid Operations: Preprint  

DOE Green Energy (OSTI)

The current state of the art of wind power forecasting in the 0- to 6-hour time frame has levels of uncertainty that are adding increased costs and risk on the U.S. electrical grid. It is widely recognized within the electrical grid community that improvements to these forecasts could greatly reduce the costs and risks associated with integrating higher penetrations of wind energy. The U.S. Department of Energy has sponsored a research campaign in partnership with the National Oceanic and Atmospheric Administration (NOAA) and private industry to foster improvements in wind power forecasting. The research campaign involves a three-pronged approach: 1) a 1-year field measurement campaign within two regions; 2) enhancement of NOAA's experimental 3-km High-Resolution Rapid Refresh (HRRR) model by assimilating the data from the field campaign; and 3) evaluation of the economic and reliability benefits of improved forecasts to grid operators. This paper and presentation provides an overview of the regions selected, instrumentation deployed, data quality and control, assimilation of data into HRRR, and preliminary results of HRRR performance analysis.

A Distributed Modeling System for Short-Term to Seasonal Ensemble Streamflow Forecasting in Snowmelt Dominated Basins  

SciTech Connect

This paper describes a distributed modeling system for short-term to seasonal water supply forecasts with the ability to utilize remotely-sensed snow cover products and real-time streamflow measurements. Spatial variability in basin characteristics and meteorology is represented using a raster-based computational grid. Canopy interception, snow accumulation and melt, and simplified soil water movement are simulated in each computational unit. The model is run at a daily time step with surface runoff and subsurface flow aggregated at the basin scale. This approach allows the model to be updated with spatial snow cover and measured streamflow using an Ensemble Kalman-based data assimilation strategy that accounts for uncertainty in weather forecasts, model parameters, and observations used for updating. Model inflow forecasts for the Dworshak Reservoir in northern Idaho are compared to observations and to April-July volumetric forecasts issued by the Natural Resource Conservation Service (NRCS) for Water Years 2000 – 2006. October 1 volumetric forecasts are superior to those issued by the NRCS, while March 1 forecasts are comparable. The ensemble spread brackets the observed April-July volumetric inflows in all years. Short-term (one and three day) forecasts also show excellent agreement with observations.

Actinide partitioning-transmutation program final report. VI. Short-term risk analysis of reprocessing, refabrication, and transportation: summary  

SciTech Connect

A Partitioning-Transmutation (PT) fuel cycle is being compared to a Reference cycle employing conventional fuel-material recovery methods. The PT cycle uses enhanced recovery methods so that most of the long-lived actinides are recycled to nuclear power plants and transmuted thereby reducing the waste toxicity. This report compares the two fuel cycles on the basis of the short-term radiological and nonradiological risks. The accidental radiological risk to the public is analyzed by estimating the probabilities of sets of accidents; the consequences are calculated using the risk, which is RAC code. Routine radiological risks to the public are estimated from the calculated release amounts, also using the CRAC code. Radiological occupational risks are determined from prior experience, projected standards, and estimates of accident risk. Nonradiological risks are calculated from the number of personnel involved, historical experience, and epidemiological studies. Result of this analysis is that the short-term risk of PT is 2.9 times greater than that of the Reference cycle, primarily due to the larger amount of industry. The nonradiological risk which is about 150 times greater than the radiological risk. If the radiological risk is consdered alone, the ratio of PT to Reference risk is 3, composed as follows: radiological operations affecting the public 5, radiological operations affecting the workers 1.7, and radiological accidents affecting the public 1.4, all in the order of decreasing risk. The absolute risk as estimated for the fuel cycle portions considered in this report is 0.91 fatality/GWe-year for the PT cycle and 0.34 fatality/GWe-year for the reference cycle; this compares with 1.5 for nuclear and 150 for coal. All of the risks assumed here are associated with the production of one billion watts of electricity (GWe) per year.

Core structure heat-up and material relocation in a BWR short-term station blackout accident  

Science Conference Proceedings (OSTI)

This paper presents an analytical and numerical analysis which evaluates the core-structure heat-up and subsequent relocation of molten core materials during a NWR short-term station blackout accident with ADS. A simplified one-dimensional approach coupled with bounding arguments is first presented to establish an estimate of the temperature differences within a BWR assembly at the point when structural material first begins to melt. This analysis leads to the conclusions that the control blade will be the first structure to melt and that at this point in time, overall temperature differences across the canister-blade region will not be more than 200 K. Next, a three-dimensional heat-transfer model of the canister-blade region within the core is presented that uses a diffusion approximation for the radiation heat transfer. This is compared to the one-dimensional analysis to establish its compatibility. Finally, the extension of the three-dimensional model to include melt relocation using a porous media type approximation is described. The results of this analysis suggest that under these conditions significant amounts of material will relocate to the core plate region and refreeze, potentially forming a significant blockage. The results also indicate that a large amount of lateral spreading of the melted blade and canister material into the fuel rod regions will occur during the melt progression process. 22 refs., 18 figs., 1 tab.

Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events  

E-Print Network (OSTI)

To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of lensing light curves. However, it is known that central perturbations can also be produced by binary companions and thus it is important to distinguish planetary signals from those induced by binary companions. In this paper, we analyze the light curves of microlensing events OGLE-2007-BLG-137/MOA-2007-BLG-091, OGLE-2007-BLG-355/MOA-2007-BLG-278, and MOA-2007-BLG-199/OGLE-2007-BLG-419, for all of which exhibit short-term perturbations near the peaks of the light curves. From detailed modeling of the light curves, we find that the perturbations of the events are caused by binary companions rather than planets. From close examination of the light curves combined with the underlying physical geometry of the lens system obtained from modeling, we find that the short time-scale caustic-crossing feature occurring at a low or a moderate base ...

Microbial dynamics in upflow anaerobic sludge blanket (UASB) bioreactor granules in response to short-term changes in substrate feed  

Science Conference Proceedings (OSTI)

The complexity and diversity of the microbial communities in biogranules from an upflow anaerobic sludge blanket (UASB) bioreactor were determined in response to short-term changes in substrate feeds. The reactor was fed simulated brewery wastewater (SBWW) (70% ethanol, 15% acetate, 15% propionate) for 1.5 months (phase 1), acetate / sulfate for 2 months (phase 2), acetate-alone for 3 months (phase 3), and then a return to SBWW for 2 months (phase 4). Performance of the reactor remained relatively stable throughout the experiment as shown by COD removal and gas production. 16S rDNA, methanogen-associated mcrA and sulfate reducer-associated dsrAB genes were PCR amplified, then cloned and sequenced. Sequence analysis of 16S clone libraries showed a relatively simple community composed mainly of the methanogenic Archaea (Methanobacterium and Methanosaeta), members of the Green Non-Sulfur (Chloroflexi) group of Bacteria, followed by fewer numbers of Syntrophobacter, Spirochaeta, Acidobacteria and Cytophaga-related Bacterial sequences. Methanogen-related mcrA clone libraries were dominated throughout by Methanobacter and Methanospirillum related sequences. Although not numerous enough to be detected in our 16S rDNA libraries, sulfate reducers were detected in dsrAB clone libraries, with sequences related to Desulfovibrio and Desulfomonile. Community diversity levels (Shannon-Weiner index) generally decreased for all libraries in response to a change from SBWW to acetate-alone feed. But there was a large transitory increase noted in 16S diversity at the two-month sampling on acetate-alone, entirely related to an increase in Bacterial diversity. Upon return to SBWW conditions in phase 4, all diversity measures returned to near phase 1 levels.

Seismic Activity of the Earth, the Cosmological Vectorial Potential And Method of a Short-term Earthquakes Forecasting  

E-Print Network (OSTI)

To the foundation of a principally new short-term forecasting method there has been laid down a theory of surrounding us world's creation and of physical vacuum as a result of interaction of byuons - discrete objects. The definition of the byuon contains the cosmological vector-potential A_g - a novel fundamental vector constant. This theory predicts a new anisotropic interaction of nature objects with the physical vacuum. A peculiar "tap" to gain new energy (giving rise to an earthquake) are elementary particles because their masses are proportional to the modulus of some summary potential A_sum that contains potentials of all known fields. The value of A_sum cannot be larger than the modulus of A_g. In accordance with the experimental results a new force associated with A_sum ejects substance from the area of the weakened A_sum along a conical formation with the opening of 100 +- 10 and the axis directed along the vector A_sum. This vector has the following coordinates in the second equatorial coordinate system: right ascension alpha = 293 +- 10, declination delta = 36 +- 10. Nearly 100% probability of an earthquake (earthquakes of 6 points strong and more by the Richter scale) arises when in the process of the earth rotation the zenith vector of a seismically dangerous region and/or the vectorial potential of Earth's magnetic fields are in a certain way oriented relative to the vector A_g. In the work, basic models and standard mechanisms of earthquakes are briefly considered, results of processing of information on the earthquakes in the context of global spatial anisotropy caused by the existence of the vector A_g, are presented, and an analysis of them is given.

Predicting Long-Term Performance of Photovoltaic Arrays Using Short-Term Test Data and an Annual Simulation Tool: Preprint (Revised)  

DOE Green Energy (OSTI)

We present a method of analysis for predicting annual performance of an in-situ photovoltaic (PV) array using short-term test data and an annual simulation tool. The method involves fitting data from a family of I-V curves (depicting current versus voltage) taken from a short-term test (1 to 3 day) of a PV array to a set of polynomial functions. These functions are used to predict the array's behaviour under a wide range of temperatures and irradiances. TRNSYS, driven by TMY2 weather data, is used to simulate the array's behaviour under typical weather conditions. We demonstrate this method by using results from a nominal 630-W array.

PSTAR: Primary and secondary terms analysis and renormalization: A unified approach to building energy simulations and short-term monitoring: A summary  

DOE Green Energy (OSTI)

This report summarizes a longer report entitled PSTAR - Primary and Secondary Terms Analysis and Renormalization. A Unified Approach to Building Energy Simulations and Short-Term Monitoring. These reports highlight short-term testing for predicting long-term performance of residential buildings. In the PSTAR method, renormalized parameters are introduced for the primary terms such that the renormalized energy balance equation is best satisfied in the least squares sense; hence, the name PSTAR. Testing and monitoring the energy performance of buildings has several important applications, among them: extrapolation to long-term performance, refinement of design tools through feedback from comparing design versus actual parameters, building-as-a-calorimeter for heating, ventilating, and air conditioning (HVAC) diagnostics, and predictive load control. By combining realistic building models, simple test procedures, and analysis involving linear equations, PSTAR provides a powerful tool for analyzing building energy as well as testing and monitoring. It forms the basis for the Short-Term Energy Monitoring (STEM) project at SERI. 3 figs., 1 tab.

An evaluation of the Gilian TRACEAIR Organic Vapor Monitoring Diffusive Badge in measuring short-term exposure levels of benzene under field conditions  

E-Print Network (OSTI)

The objective of this research is to evaluate the performance of the Gilian TRACEAIR Organic Vapor Monitoring I (OVMI) Diffusive Badge in measuring short-term benzene exposures under field conditions. In general, a diffusive badge is a device which is capable of taking samples of gas or vapor pollutants from the atmosphere at a rate controlled by a physical process such as diffusion through a static layer. Diffusive badges continue to flood the industrial hygiene market as an alternative means to charcoal tubes for sampling organic vapors. The OVMI badge has been on the market since 1990, and is the only diffusive sampler that offers dual sampling rates for measuring organic vapors. This dual sampling rate feature allows one the flexibility of sampling at 3 5 to I 00 mL/@n depending on the vapors being sampled. The OVM I badge has been designed to monitor short-term exposure limits (STEL) and long-term limits with only negligible modifications to the badge housing. Side-by-side benzene STEL concentrations were measured in a Texas Gulf Coast refinery implementing two OVM I badges, an SKC charcoal tube, and a Tedlar bag used for gas chromatograph analyses. The results of the study indicated that a) no significant concentration differences were found between the badges; b) the badges overestimated the charcoal tube on average by 54%, although their performance comparisons were highly predictable based on linear regression; and c) the results of the Tedlar baga?s chromatograph comparisons were inconclusive. Factors which might have contributed to the discrepancy between the charcoal tube and badges are possible concentration gradients and starvation effects occurring at the samplers' inlet face, interference from other competing vapors, and an overestimated badge sampling rate when sampling at the maximum uptake rate. Collectively, the outcomes of this research suggests that a correction factor in the badge's sampling rate might prove useful as a means of correcting for short-term overestimations when sampling for benzene under field conditions. It is hoped that the contents of this research serve as an useful aid for those specifically interested in the OVMI badge and for those whose line of work involve passive sampling.

The University of Minnesota aquifer thermal energy storage (ATES) field test facility -- system description, aquifer characterization, and results of short-term test cycles  

DOE Green Energy (OSTI)

Phase 1 of the Aquifer Thermal Energy Storage (ATES) Project at the University of Minnesota was to test the feasibility, and model, the ATES concept at temperatures above 100{degrees}C using a confined aquifer for the storage and recovery of hot water. Phase 1 included design, construction, and operation of a 5-MW thermal input/output field test facility (FTF) for four short-term ATES cycles (8 days each of heat injection, storage, and heat recover). Phase 1 was conducted from May 1980 to December 1983. This report describes the FTF, the Franconia-Ironton-Galesville (FIG) aquifer used for the test, and the four short-term ATES cycles. Heat recovery; operational experience; and thermal, chemical, hydrologic, and geologic effects are all included. The FTF consists of monitoring wells and the source and storage well doublet completed in the FIG aquifer with heat exchangers and a fixed-bed precipitator between the wells of the doublet. The FIG aquifer is highly layered and a really anisotropic. The upper Franconia and Ironton-Galesville parts of the aquifer, those parts screened, have hydraulic conductivities of {approximately}0.6 and {approximately}1.0 m/d, respectively. Primary ions in the ambient ground water are calcium and magnesium bicarbonate. Ambient temperature FIG ground water is saturated with respect to calcium/magnesium bicarbonate. Heating the ground water caused most of the dissolved calcium to precipitate out as calcium carbonate in the heat exchanger and precipitator. Silica, calcium, and magnesium were significantly higher in recovered water than in injected water, suggesting dissolution of some constituents of the aquifer during the cycles. Further work on the ground water chemistry is required to understand water-rock interactions.

Applicability of digital terrain analyses to wind energy prospecting and siting  

DOE Green Energy (OSTI)

The recent publication of the Digital Elevation Model (DEM) database by the US Geological Survey (USGS) has provided a unique opportunity for the development of cost-effective wind energy prospecting technology. This database contains terrain elevation values on a Latitude-Longitude grid with a resolution of 3 arc-seconds (about 90 m) for the contiguous United States, Hawaii, and Puerto Rico. This database has been coupled with software that will produce shaded-relief maps on a laser printer in a format compatible with the state wind power maps in the US wind energy atlas. By providing a much higher resolution of the terrain features than was possible when the US atlas was prepared, these maps can be useful in general wind prospecting activities. As highly resolved as the 90-m DEM data seem to be when compared to the atlas grid, they still appear to be too coarse to resolve terrain features in the detail required for local wind flow characterization and wind plant layout. Gridded terrain data at about 10-m resolution are available from the USGS for some areas of the United States. In areas where these data are unavailable, they may be generated by digitizing and gridding the contours from a 1:24,000-scale USGS map over the area of interest. Comparisons of terrain profiles from cross sections of the 10-m and 90-m data provide an indication of the effect of resolution on the reliability of terrain feature representation. Oblique views of the terrain in shaded-relief format provide a dramatic enhancement of the shape and relative position of features of interest.

Cost Trends Cost Trends Figure 1: Cost of Energy and Cumulative Domestic Capacity This graph shows how the cumulative domestic wind capacity (MW) has increased since 1980, while the cost of energy from wind power has declined by a factor of approximately 20 times during the same period but has increased slightly since 2001. Click on the image to view a larger version. This graph shows how the cumulative domestic wind capacity (MW) has increased since 1980, while the cost of energy from wind power has declined by a factor of approximately 20 times during the same period but has increased slightly since 2001. View a larger version of the graph. Overall, the wind industry is experiencing long-term decreases in the cost to produce wind-generated electricity (Figure 1), despite recent short-term increases in upfront equipment costs. Even in the short term, however, the effect of increases in up-front capital costs on the cost of energy from wind power projects has been dampened by improvements in energy capture from the wind and decreases in operating and maintenance costs.

Comparison of MELCOR modeling techniques and effects of vessel water injection on a low-pressure, short-term, station blackout at the Grand Gulf Nuclear Station  

SciTech Connect

A fully qualified, best-estimate MELCOR deck has been prepared for the Grand Gulf Nuclear Station and has been run using MELCOR 1.8.3 (1.8 PN) for a low-pressure, short-term, station blackout severe accident. The same severe accident sequence has been run with the same MELCOR version for the same plant using the deck prepared during the NUREG-1150 study. A third run was also completed with the best-estimate deck but without the Lower Plenum Debris Bed (BH) Package to model the lower plenum. The results from the three runs have been compared, and substantial differences have been found. The timing of important events is shorter, and the calculated source terms are in most cases larger for the NUREG-1150 deck results. However, some of the source terms calculated by the NUREG-1150 deck are not conservative when compared to the best-estimate deck results. These results identified some deficiencies in the NUREG-1150 model of the Grand Gulf Nuclear Station. Injection recovery sequences have also been simulated by injecting water into the vessel after core relocation started. This marks the first use of the new BH Package of MELCOR to investigate the effects of water addition to a lower plenum debris bed. The calculated results indicate that vessel failure can be prevented by injecting water at a sufficiently early stage. No pressure spikes in the vessel were predicted during the water injection. The MELCOR code has proven to be a useful tool for severe accident management strategies.

Terrain effects in resistivity and magnetotelluric surveys  

Science Conference Proceedings (OSTI)

A three-dimensional finite element computer algorithm which can accommodate arbitrarily complex topography and subsurface structure, has been developed to model the resistivity response of the earth. The algorithm has undergone extensive evaluation and is believed to provide accurate results for realistic earth models. Testing included comparison to scale model measurements, analytically calculated solutions, and results calculated numerically by other independent means. Computer modeling experiments have demonstrated that it is possible to remove the effect of topography on resistivity data under conditions where such effects dominate the response. This can be done without resorting to lengthy and costly trial and error computer modeling. After correction, the data can be interpreted with confidence that the anomalies are due only to subsurface structure. The results of case studies on resistivity field data measured in high relief topography are discussed.

Generating color terrain images in an emergency response system  

Science Conference Proceedings (OSTI)

The Atmospheric Release Advisory Capability (ARAC) provides real-time assessments of the consequences resulting from an atmospheric release of radioactive material. In support of this operation, a system has been created which integrates numerical models, data acquisition systems, data analysis techniques, and professional staff. Of particular importance is the rapid generation of graphical images of the terrain surface in the vicinity of the accident site. A terrain data base and an associated acquisition system have been developed that provide the required terrain data. This data is then used as input to a collection of graphics programs which create and display realistic color images of the terrain. The graphics system currently has the capability of generating color shaded relief images from both overhead and perspective viewpoints within minutes. These images serve to quickly familiarize ARAC assessors with the terrain near the release location, and thus permit them to make better informed decisions in modeling the behavior of the released material. 7 refs., 8 figs.

September 2012 Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

Highlights  Brent crude oil spot prices have increased at a relatively steady pace from their 2012 low of $89 per barrel on June 25 to their recent high of $117 per barrel on August 23 because of the seasonal tightening of oil markets and continuing unexpected production outages. EIA expects Brent crude oil prices to fall from recent highs over the rest of 2012, averaging $111 per barrel over the last 4 months of 2012 and $103 per barrel in 2013. West Texas Intermediate (WTI) crude oil spot prices rose by a more modest $17 per barrel between June 25 and August 23, as the WTI discount to Brent crude oil widened from $10 per barrel to $22 per barrel. EIA expects WTI spot prices to average

Short-Term World Oil Price Forecast  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: This graph shows monthly average spot West Texas Intermediate crude oil prices. Spot WTI crude oil prices peaked last fall as anticipated boosts to world supply from OPEC and other sources did not show up in actual stocks data. So where do we see crude oil prices going from here? Crude oil prices are expected to be about $28-$30 per barrel for the rest of this year, but note the uncertainty bands on this projection. They give an indication of how difficult it is to know what these prices are going to do. Also, EIA does not forecast volatility. This relatively flat forecast could be correct on average, with wide swings around the base line. Let's explore why we think prices will likely remain high, by looking at an important market barometer - inventories - which measures the

Online short-term solar power forecasting  

SciTech Connect

This paper describes a new approach to online forecasting of power production from PV systems. The method is suited to online forecasting in many applications and in this paper it is used to predict hourly values of solar power for horizons of up to 36 h. The data used is 15-min observations of solar power from 21 PV systems located on rooftops in a small village in Denmark. The suggested method is a two-stage method where first a statistical normalization of the solar power is obtained using a clear sky model. The clear sky model is found using statistical smoothing techniques. Then forecasts of the normalized solar power are calculated using adaptive linear time series models. Both autoregressive (AR) and AR with exogenous input (ARX) models are evaluated, where the latter takes numerical weather predictions (NWPs) as input. The results indicate that for forecasts up to 2 h ahead the most important input is the available observations of solar power, while for longer horizons NWPs are the most important input. A root mean square error improvement of around 35% is achieved by the ARX model compared to a proposed reference model. (author)

All-Terrain Vehicle: Non-Road Electric Vehicle Demonstration  

Science Conference Proceedings (OSTI)

An all-terrain vehicle (ATV) is defined by the American National Standards Institute (ANSI) as one that travels on low-pressure tires, with a seat that is straddled by the operator or the operator and one passenger, along with handlebars for steering control. Most ATVs are gas powered, but replacement of gas-powered ATVs with an electric equivalent could reduce emissions output, fuel consumption, and other petrochemical byproducts resulting from operation of these vehicles. An electric ATV offers all of ...

Atmospheric transport in complex terrain at Los Alamos, Area G  

Science Conference Proceedings (OSTI)

This report documents the atmospheric dispersion used in the Area G Performance Assessment for off-site airborne dose calculations. Potential airborne contaminants from the mesa top disposal facility disperse in the complex terrain dominated by narrow mesas in parallel to narrow canyons. The dispersion is characterized by site-specific values of X/Q [(Ci/m{sup 3})/(Ci/s)] at each of two designated receptor locations, a {open_quote}maximum off-site dose{close_quote} location and a nearby population center (White Rock, NM). The values of X/Q in each of the sixteen wind sectors are first estimated with the CAP-88 computer code using 1992 annual meteorologic data from Area G and assuming an area source for release. This data captures the dominant wind direction on the mesa tops from the SSW. These dispersion parameters are assumed to apply to open, flat terrain and must be corrected for the complex mesa and canyon terrain terrain surrounding the Area G site. Additional meteorologic data has been collected over two years from six remote temporary meteorological stations operated on the mesas and in the canyons immediately around Area G. These data indicate that the wind flow in the canyons is exclusively bimodel, flowing up canyon during the day and down canyon at night. It is conservatively assumed that all ground level releases from Area G which blow out across an adjacent canyon become entrained in the canyon flow. This effectively combines the contaminant release for several sectors into a single canyon flow which is upstream during the day or downstream at night. This canyon channeling mechanism is implemented in the model by summing the wind sector dispersion factors over those sectors appropriate to the geometry for a release from Area G toward either adjacent canyon.

Impacts of Rising Construction and Equipment Costs on Energy Industries (released in AEO2007)  

Reports and Publications (EIA)

Costs related to the construction industry have been volatile in recent years. Some of the volatility may be related to higher energy prices. Prices for iron and steel, cement, and concretecommodities used heavily in the construction of new energy projects rose sharply from 2004 to 2006, and shortages have been reported. How such price fluctuations may affect the cost or pace of new development in the energy industries is not known with any certainty, and short-term changes in commodity prices are not accounted for in the 25-year projections in AEO2007. Most projects in the energy industries require long planning and construction lead times, which can lessen the impacts of short-term trends.

On-the-Fly Decompression and Rendering of Multiresolution Terrain  

SciTech Connect

We present a streaming geometry compression codec for multiresolution, uniformly-gridded, triangular terrain patches that supports very fast decompression. Our method is based on linear prediction and residual coding for lossless compression of the full-resolution data. As simplified patches on coarser levels in the hierarchy already incur some data loss, we optionally allow further quantization for more lossy compression. The quantization levels are adaptive on a per-patch basis, while still permitting seamless, adaptive tessellations of the terrain. Our geometry compression on such a hierarchy achieves compression ratios of 3:1 to 12:1. Our scheme is not only suitable for fast decompression on the CPU, but also for parallel decoding on the GPU with peak throughput over 2 billion triangles per second. Each terrain patch is independently decompressed on the fly from a variable-rate bitstream by a GPU geometry program with no branches or conditionals. Thus we can store the geometry compressed on the GPU, reducing storage and bandwidth requirements throughout the system. In our rendering approach, only compressed bitstreams and the decoded height values in the view-dependent 'cut' are explicitly stored on the GPU. Normal vectors are computed in a streaming fashion, and remaining geometry and texture coordinates, as well as mesh connectivity, are shared and re-used for all patches. We demonstrate and evaluate our algorithms on a small prototype system in which all compressed geometry fits in the GPU memory and decompression occurs on the fly every rendering frame without any cache maintenance.

Life cycle cost and risk estimation of environmental management options  

SciTech Connect

The evaluation process is demonstrated in this paper through comparative analysis of two alternative scenarios identified for the management of the alpha-contaminated fixed low-level waste currently stored at INEL. These two scenarios, the Base Case and the Delay Case, are realistic and based on actual data, but are not intended to exactly match actual plans currently being developed at INEL. Life cycle cost estimates were developed for both scenarios using the System Cost Model; resulting costs are presented and compared. Life cycle costs are shown as a function of time and also aggregated by pretreatment, treatment, storage, and disposal activities. Although there are some short-term cost savings for the Delay Case, cumulative life cycle costs eventually become much higher than costs for the Base Case over the same period of time, due mainly to the storage and repackaging necessary to accommodate the longer Delay Case schedule. Life cycle risk estimates were prepared using a new risk analysis method adapted to the System Cost Model architecture for automated, systematic cost/risk applications. Relative risk summaries are presented for both scenarios as a function of time and also aggregated by pretreatment, treatment, storage, and disposal activities. Relative risk of the Delay Case is shown to be higher than that of the Base Case. Finally, risk and cost results are combined to show how the collective information can be used to help identify opportunities for risk or cost reduction and highlight areas where risk reduction can be achieved most economically.

Atmospheric studies in complex terrain: a planning guide for future studies  

Science Conference Proceedings (OSTI)

The objective of this study is to assist the US Department of Energy in Conducting its atmospheric studies in complex terrain (ASCOT0 by defining various complex terrain research systems and relating these options to specific landforms sites. This includes: (1) reviewing past meteorological and diffusion research on complex terrain; (2) relating specific terrain-induced airflow phenomena to specific landforms and time and space scales; (3) evaluating the technical difficulty of modeling and measuring terrain-induced airflow phenomena; and (4) avolving severdal research options and proposing candidate sites for continuing and expanding field and modeling work. To evolve research options using variable candidate sites, four areas were considered: site selection, terrain uniqueness and quantification, definition of research problems and research plans. 36 references, 111 figures, 20 tables.

Ultrawideband radar clutter measurements of forested terrain, 1991--1992  

Science Conference Proceedings (OSTI)

The ultrawideband (UWB) radar clutter measurements project was conducted to provide radar clutter data for new ultrawideband radar systems which are currently under development. A particular goal of this project is to determine if conventional narrow band clutter data may be extrapolated to the UWB case. This report documents measurements conducted in 1991 and additional measurements conducted in 1992. The original project consisted of clutter measurements of forested terrain in the Olympic National Forest near Sequim, WA. The impulse radar system used a 30 kW peak impulse source with a 2 Gigasample/second digitizer to form a UHF (300--1000 MHz) ultrawideband impulse radar system. Additional measurements were conducted in parallel using a Systems Planning Corporation (SPC) step-chirp radar system. This system utilized pulse widths of 1330 nanoseconds over a bandwidth of 300--1000 MHz to obtain similar resolution to the impulse system. Due to the slow digitizer data throughput in the impulse radar system, data collection rates were significantly higher using the step-chirp system. Additional forest clutter measurements were undertaken in 1992 to increase the amount of data available, and especially to increase the amount of data from the impulse radar system.

An augmented reality system for military operations in urban terrain  

E-Print Network (OSTI)

Many future military operations are expected to occur in urban environments. These complex, 3D battlefields introduce many challenges to the dismounted warfighter. Better situational awareness is required for effective operation in urban environments. However, delivering this information to the dismounted warfighter is extremely difficult. For example, maps draw a user's attention away from the environment and cannot directly represent the three-dimensional nature of the terrain. To overcome these difficulties, we are developing the Battlefield Augmented Reality System (BARS). The system consists of a wearable computer, a wireless network system, and a tracked see-through head-mounted display (HMD). The computer generates graphics that, from the user's perspective, appear to be aligned with the actual environment. For example, a building could be augmented to show its name, a plan of its interior, icons to represent reported sniper locations, and the names of adjacent streets. This paper surveys the current state of development of BARS and describes ongoing research efforts. We describe four major research areas. The first is the development of an effective, efficient user interface for displaying data and processing user inputs. The second is the capability for collaboration between multiple BARS users and other systems. Third, we describe the current hardware for both a mobile and indoor prototype system. Finally, we

Accurate Wind Characterization in Complex Terrain Using the Immersed Boundary Method  

DOE Green Energy (OSTI)

This paper describes an immersed boundary method (IBM) that facilitates the explicit resolution of complex terrain within the Weather Research and Forecasting (WRF) model. Two different interpolation methods, trilinear and inverse distance weighting, are used at the core of the IBM algorithm. Functional aspects of the algorithm's implementation and the accuracy of results are considered. Simulations of flow over a three-dimensional hill with shallow terrain slopes are preformed with both WRF's native terrain-following coordinate and with both IB methods. Comparisons of flow fields from the three simulations show excellent agreement, indicating that both IB methods produce accurate results. However, when ease of implementation is considered, inverse distance weighting is superior. Furthermore, inverse distance weighting is shown to be more adept at handling highly complex urban terrain, where the trilinear interpolation algorithm breaks down. This capability is demonstrated by using the inverse distance weighting core of the IBM to model atmospheric flow in downtown Oklahoma City.

Environmental and Life Cycle Cost Reduction Potential Environmental and Life Cycle Cost Reduction Potential of Ground Source Heat Pump (GSHP) in Hot and Humid Climate Geothermal Project Jump to: navigation, search Last modified on July 22, 2011. Project Title Analysis of Energy, Environmental and Life Cycle Cost Reduction Potential of Ground Source Heat Pump (GSHP) in Hot and Humid Climate Project Type / Topic 1 Recovery Act - Geothermal Technologies Program: Ground Source Heat Pumps Project Type / Topic 2 Topic Area 2: Data Gathering and Analysis Project Description It has been widely recognized that the energy saving benefits of GSHP systems are best realized in the northern and central regions where heating needs are dominant or both heating and cooling loads are comparable. For hot and humid climate such as in the states of FL, LA, TX, southern AL, MS, GA, NC and SC, buildings have much larger cooling needs than heating needs. The Hybrid GSHP (HGSHP) systems therefore have been developed and installed in some locations of those states, which use additional heat sinks (such as cooling tower, domestic water heating systems) to reject excess heat. Despite the development of HGSHP the comprehensive analysis of their benefits and barriers for wide application has been limited and often yields non-conclusive results. In general, GSHP/HGSHP systems often have higher first costs than conventional systems making short-term economics unattractive. Addressing these technical and financial barriers call for additional evaluation of innovative utility programs, incentives and delivery approaches.

Comparison of high-speed rail and maglev system costs  

SciTech Connect

This paper compares the two modes of transportation, and notes important similarities and differences in the technologies and in how they can be implemented to their best advantage. Problems with making fair comparisons of the costs and benefits are discussed and cost breakdowns based on data reported in the literature are presented and discussed in detail. Cost data from proposed and actual construction projects around the world are summarized and discussed. Results from the National Maglev Initiative and the recently-published Commercial Feasibility Study are included in the discussion. Finally, estimates will be given of the expected cost differences between HSR and maglev systems implemented under simple and complex terrain conditions. The extent to which the added benefits of maglev technology offset the added costs is examined.

Examining the effectiveness of municipal solid waste management systems: An integrated cost-benefit analysis perspective with a financial cost modeling in Taiwan  

Science Conference Proceedings (OSTI)

In order to develop a sound material-cycle society, cost-effective municipal solid waste (MSW) management systems are required for the municipalities in the context of the integrated accounting system for MSW management. Firstly, this paper attempts to establish an integrated cost-benefit analysis (CBA) framework for evaluating the effectiveness of MSW management systems. In this paper, detailed cost/benefit items due to waste problems are particularly clarified. The stakeholders of MSW management systems, including the decision-makers of the municipalities and the citizens, are expected to reconsider the waste problems in depth and thus take wise actions with the aid of the proposed CBA framework. Secondly, focusing on the financial cost, this study develops a generalized methodology to evaluate the financial cost-effectiveness of MSW management systems, simultaneously considering the treatment technological levels and policy effects. The impacts of the influencing factors on the annual total and average financial MSW operation and maintenance (O and M) costs are analyzed in the Taiwanese case study with a demonstrative short-term future projection of the financial costs under scenario analysis. The established methodology would contribute to the evaluation of the current policy measures and to the modification of the policy design for the municipalities.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

The Energy Information Administration (EIA) projects that natural gas prices will remain relatively high for the rest of 2004. Wellhead prices are expected to average $5.41 per MMBtu through the end of the storage refill season (October 31) and $5.59 in November and December. Spot prices (composites for producing-area hubs) averaged about $5.30 per MMBtu in the first quarter of this year but are currently near $6.00. Barring cooler-than-normal weather this summer, the likelihood appears small that spot prices will fall significantly below $5.65 per MMBtu for the rest of 2004. Overall in 2004, spot prices will likely average $5.62 per MMBtu and wellhead prices will average $5.33. In 2005, spot prices are expected to increase to $5.90 per MMBtu. As in other recent projections, this outcome depends on modest growth in domestic production and total available supply (including imports and storage inventories) in both 2004 and 2005. Underground storage facilities reported net injections of 199 Bcf for April, well above the previous 5-year average of 139 Bcf. At the end of April, storage stocks were only about 2 percent below the 5-year average level and 37 percent higher than last year at this time based on monthly survey data.

The increase, while substantial, still leaves average prices low compared to pre-1998 history, especially in inflation-adjusted terms. * Supplies: expected to be adequate, overall. Beginning-of-season inventories were even with the 1998 level, which was at the high end of the normal range. However, some refinery problems on the West Coast have tightened things up, at least temporarily. * Demand: up 2.0 percent from last summer due to solid economic growth and low (albeit rising) fuel prices; highway travel may reach 1.4 trillion miles for the

Short-Term Energy Outlook April 2000--STEO Preface  

Gasoline and Diesel Fuel Update (EIA)

April 2000 April 2000 Summer 2000 Motor Gasoline Outlook Summary For the upcoming summer season (April to September), motor gasoline markets are projected to exhibit an extraordinarily tight supply/demand balance. * Retail gasoline prices (regular grade) are expected to average $1.46 per gallon, 25 percent higher than last summer's average of $1.17 per gallon. That projection also exceeds the previous (current-dollar) record summer average of $1.35 recorded in 1981. Nominal prices are expected to reach a peak of $1.52 per gallon in April-a new record--and decline steadily to $1.39 per gallon by September due to the impact of increases in world-wide crude oil production. These projections presume no disruptions of refinery motor gasoline production. *

Safeguards Education and Training: Short Term Supply vs. Demand  

SciTech Connect

Much has been written and discussed in the past several years about the effect of the aging nuclear workforce on the sustainability of the U.S. safeguards and security infrastructure. This paper discusses the 10-15 year supply and demand forecast for nuclear material control and accounting specialists. The demand side of the review includes control and accounting of the materials at U.S. DOE and NRC facilities, and the federal oversight of those MC&A programs. The cadre of experts referred to as 'MC&A Specialists' available to meet the demand goes beyond domestic MC&A to include international programs, regulatory and inspection support, and so on.

Short-Term Wind Generation Forecasting Using Artificial Neural Networks  

Science Conference Proceedings (OSTI)

Wind power is a highly intermittent power output resource that cannot be bid competitively in a traditional market due to scheduling problems associated with the resource. The California Independent System Operator (CAISO) has proposed a unique market arrangement that makes such bidding possible. The central part of the arrangement is a provision that deviations between metered and scheduled energy for participating intermittent renewable resources will be averaged across a calendar month, and paid or ch...

Short-term microbial testing of shale oil materials  

DOE Green Energy (OSTI)

Paraho/Sohio Shale Oil was found to be mutagenic in the Ames assay when assayed with the frameshift strain TA98 and incorporating metabolic activation with rat liver homogenates (Aroclor induced S-9). The mutagenic activity was contributed by the organic constituents of the basic and the neutral fractions. Hydrotreatment of the shale oil abolished the mutagenic activity. Results obtained in the yeast assay supported these observations. Refined oil samples from Paraho/Sohio refinery were not mutagenic. The samples rank for their mutagenic activity as coal oils > shale oil > natural petroleum crudes.
