No maintenance -- no energy efficiency  

SciTech Connect (OSTI)

Field investigations illustrate that it is not realistic to expect new high-tech equipment to function for a full life expectancy at high efficiency without significant operations and maintenance (O&M). A simple walk through inspection of most buildings reveals extensive equipment that is being operated on manual override, is incorrectly adjusted and operating inefficiently, or is simply inoperative. This point is illustrated with two examples at Robins Air Force Base, Georgia. The first describes development of a comprehensive, base-wide, steam trap maintenance program. The second describes a measured evaluation from a typical office building. The objective of both examples was to assess the importance of proper O&M. The proposed ``O&M First`` philosophy will result in more efficient building HVAC operation, provide improved services to the building occupants, and reduce energy consumption and unscheduled equipment repair/replacement. Implementation of a comprehensive O&M program will result in a 15--25% energy savings. The O&M foundation that is established will allow other energy conservation activities such is demand side management or energy management and control systems, to achieve and maintain their expected energy savings.

Development of an Efficient Maintenance Scheme for Peak Efficiency of Boilers  

E-Print Network [OSTI]

Abstract––Presently the world has enormous advancement in science and technology the topic considered here is just a drop out of an ocean of knowledge. Higher product quality, better reliability, better availability of plants, optimization of cost and efficient working of boilers is the chief concern now a days. Generally the production can be increased by the efficient use of boilers and hence there is a lot of scope to minimize the boiler operation cost. A boiler maintenance improvement program must include two aspects: (1) action to bring the boiler to peak efficiency and (2) action to maintain the efficiency at the maximum level. Good maintenance and efficiency start with having a working knowledge of the components associated with the boiler, keeping records, etc., and end with cleaning heat transfer surfaces, adjusting the air-to-fuel ratio, etc. A well-planned maintenance program avoids unnecessary down time or costly repairs. It also promotes safety and aids boiler code and local inspectors. An inspection schedule listing the procedures should be established. Thus in this paper an attempt is made to develop an efficient maintenance scheme by which boilers can be used with peak efficiency.

An integrated cost model for production scheduling and perfect maintenance  

Science Journals Connector (OSTI)

Production scheduling deals with scheduling production jobs on a machine (single or multiple) in order to optimise a specific objective such as total weighted completion times or total weighted tardiness. The assumption that machines are always available for processing jobs is generally used in the production scheduling literature. In reality, machines often are unavailable due to preventive maintenance activities or machine failure. Production scheduling and preventive maintenance planning are interrelated, but are most often treated separately. This interdependency seems to be overlooked in the literature. This work integrates, simultaneously, the decisions of preventive maintenance and job order sequencing for a single machine. The objective is to find the job order sequence and maintenance decisions that would minimise the expected cost.

Proof test results were analyzed and compared with a proposed life cycle curve or hazard function and the limit of useful life. Relief valve proof testing procedures, statistical modeling, data collection processes, and time-in-service trends are presented. The resulting analysis of test data allows for the estimation of the PFD. Extended maintenance intervals to the limit of useful life as well as methodologies and practices for improving relief valve performance and reliability are discussed. A generic cost-benefit analysis and an expected life cycle cost reduction concludes that $90 million maintenance dollars might be avoided for a population of 3000 valves over 20 years.

Will 10 MW Wind Turbines Bring Down the Operation and Maintenance Cost of Offshore Wind Farms?  

Science Journals Connector (OSTI)

Abstract Larger wind turbines are believed to be advantageous from an investment and installation perspective, since costs for installation and inner cabling are dependent mainly on the number of wind turbines and not their size. Analogously, scaling up the turbines may also be argued to be advantageous from an operation and maintenance (O&M) perspective. For a given total power production of the wind farm, larger wind turbines give a smaller number of individual machines that needs to be maintained and could therefore give smaller O&M costs. However, the O&M costs are directly dependent on how failure rates, spare part costs, and time needed by technicians to perform each maintenance task and will develop for larger wind turbines. A simulation study is carried out with a discrete-event simulation model for the operational phase of an offshore wind farm, comparing the O&M costs of a wind farm consisting of 5 MW turbines with a wind farm consisting of 10 MW turbines. Simulation results confirm that O&M costs decrease when replacing two 5 MW turbines by one 10 MW turbine, if the total production capacity and all other parameters are kept equal. However, whether larger wind turbines can contribute to a reduction of cost of energy from an O&M perspective is first and foremost dependent on how the failure rates and maintenance durations for such wind turbines will develop compared to 5 MW wind turbines. Based on the results of this analysis, it is concluded that higher failure rates and maintenance durations rapidly are counterbalancing the benefits of larger wind turbines.

Wind turbine reliability : understanding and minimizing wind turbine operation and maintenance costs.  

SciTech Connect (OSTI)

Wind turbine system reliability is a critical factor in the success of a wind energy project. Poor reliability directly affects both the project's revenue stream through increased operation and maintenance (O&M) costs and reduced availability to generate power due to turbine downtime. Indirectly, the acceptance of wind-generated power by the financial and developer communities as a viable enterprise is influenced by the risk associated with the capital equipment reliability; increased risk, or at least the perception of increased risk, is generally accompanied by increased financing fees or interest rates. Cost of energy (COE) is a key project evaluation metric, both in commercial applications and in the U.S. federal wind energy program. To reflect this commercial reality, the wind energy research community has adopted COE as a decision-making and technology evaluation metric. The COE metric accounts for the effects of reliability through levelized replacement cost and unscheduled maintenance cost parameters. However, unlike the other cost contributors, such as initial capital investment and scheduled maintenance and operating expenses, costs associated with component failures are necessarily speculative. They are based on assumptions about the reliability of components that in many cases have not been operated for a complete life cycle. Due to the logistical and practical difficulty of replacing major components in a wind turbine, unanticipated failures (especially serial failures) can have a large impact on the economics of a project. The uncertainty associated with long-term component reliability has direct bearing on the confidence level associated with COE projections. In addition, wind turbine technology is evolving. New materials and designs are being incorporated in contemporary wind turbines with the ultimate goal of reducing weight, controlling loads, and improving energy capture. While the goal of these innovations is reduction in the COE, there is a potential impact on reliability whenever new technologies are introduced. While some of these innovations may ultimately improve reliability, in the short term, the technology risks and the perception of risk will increase. The COE metric used by researchers to evaluate technologies does not address this issue. This paper outlines the issues relevant to wind turbine reliability for wind turbine power generation projects. The first sections describe the current state of the industry, identify the cost elements associated with wind farm O&M and availability and discuss the causes of uncertainty in estimating wind turbine component reliability. The latter sections discuss the means for reducing O&M costs and propose O&M related research and development efforts that could be pursued by the wind energy research community to reduce COE.

Lutz, Xiaomin Liu, Camilla Dunham Whitehead, and James E. McMahon Document Number LBNL-45618 Date Published May 4 Abstract Economic impacts on individual consumers from possible revisions to U.S. residential water heater energy-efficiency standards are examined using a life-cycle cost (LCC) analysis. LCC is the consumer's cost of purchasing and installing a water heater and operating it over its lifetime. This approach makes it possible to evaluate the economic impacts on individual consumers from the revised standards. The methodology allows an examination of groups of the population which benefit or lose from suggested efficiency standards. The results show that the economic benefits to consumers are significant. At the efficiency level examined in this paper, 35% of households with electric water heaters experience LCC savings, with an average savings of $106, while 4% show LCC losses, with an average loss of $40 compared to a pre-standard LCC average of $2,565. The remainder of the population (61%) are largely unaffected.

Cost assessment of efficiency losses in hydroelectric plants  

Science Journals Connector (OSTI)

Some important real-time tasks of the independent system operator (ISO) are the monitoring and control of power system events (load deviations and contingencies). These events are usually managed by the ISO using operating reserve ancillary services. These services represent an additional capacity (MW) available in generators and some interruptible loads. Generators must change their operating points in order that this capacity can remain available. These changes might lead to efficiency losses in energy production. In systems with a high percentage of hydroelectric production, hydroelectric plants need to know the impact of ancillary services on their profits. This work therefore analyzes the cost of efficiency losses due to operating reserve availability in hydroelectric generators. A method to calculate this cost component is proposed using a unit commitment dispatch for a single hydroelectric plant. This dispatch is performed without considering the operating reserve availability and is compared with the traditional dispatch, which takes into account the availability of operating reserve. The proposal is used to calculate the cost of efficiency losses on a Brazilian hydroelectric generator. We found that the cost of efficiency losses can be considerable when compared to the incomes of a hydroelectric plant in the short-term market.

Steam turbine maintenance and repair technology: Reducing planned-outage costs  

SciTech Connect (OSTI)

The North American Electric Reliability Council (NAERC) reported that the average loss of equivalent availability per outage for a major fossil turbine overhaul is 323,000 MW-HR. The Electric Power Research Institute (EPRI) Generation and Storage Division, is in the first phase of a major research project to reduce the duration and/or frequency of steam turbine maintenance outages. This project consists of an assessment of the current state-of-the-art turbine maintenance and repair techniques and technologies. It is based on a review of current turbine maintenance practices of the US, European, Japanese, and Australian utility industries. Emphasized are maintenance and repair activities that have the most significant impact on outage duration or frequency. Twenty-six key turbine maintenance activities and the current best techniques were identified for use by utility maintenance personnel. Overall outage durations could be reduced if the duration of these activities were shortened or if they were performed more effectively. Recommended projects for development of advanced steam turbine maintenance technology were identified. 29 refs., 46 figs., 9 tabs.

Cost-Effective Integration of Efficient Low-Lift Base Load Cooling Equipment  

SciTech Connect (OSTI)

The long-term goal of DOE’s Commercial Buildings Integration subprogram is to develop cost-effective technologies and building practices that will enable the design and construction of net Zero Energy Buildings — commercial buildings that produce as much energy as they use on an annual basis — by 2025. To support this long-term goal, DOE further called for — as part of its FY07 Statement of Needs — the development by 2010 of “five cost-effective design technology option sets using highly efficient component technologies, integrated controls, improved construction practices, streamlined commissioning, maintenance and operating procedures that will make new and existing commercial buildings durable, healthy and safe for occupants.” In response, PNNL proposed and DOE funded a scoping study investigation of one such technology option set, low-lift cooling, that offers potentially exemplary HVAC energy performance relative to ASHRAE Standard 90.1-2004. The primary purpose of the scoping study was to estimate the national technical energy savings potential of this TOS.

Techno-Economic Feasibility of Highly Efficient Cost-Effective Thermoelectric-SOFC Hybrid Power Generation Systems  

SciTech Connect (OSTI)

Solid oxide fuel cell (SOFC) systems have the potential to generate exhaust gas streams of high temperature, ranging from 400 to 800 C. These high temperature gas streams can be used for additional power generation with bottoming cycle technologies to achieve higher system power efficiency. One of the potential candidate bottoming cycles is power generation by means of thermoelectric (TE) devices, which have the inherent advantages of low noise, low maintenance and long life. This study was to analyze the feasibility of combining coal gas based SOFC and TE through system performance and cost techno-economic modeling in the context of multi-MW power plants, with 200 kW SOFC-TE module as building blocks. System and component concepts were generated for combining SOFC and TE covering electro-thermo-chemical system integration, power conditioning system (PCS) and component designs. SOFC cost and performance models previously developed at United Technologies Research Center were modified and used in overall system analysis. The TE model was validated and provided by BSST. The optimum system in terms of energy conversion efficiency was found to be a pressurized SOFC-TE, with system efficiency of 65.3% and cost of $390/kW of manufacturing cost. The pressurization ratio was approximately 4 and the assumed ZT of the TE was 2.5. System and component specifications were generated based on the modeling study. The major technology and cost barriers for maturing the system include pressurized SOFC stack using coal gas, the high temperature recycle blowers, and system control design. Finally, a 4-step development roadmap is proposed for future technology development, the first step being a 1 kW proof-of-concept demonstration unit.

Energy Efficiency Improvement and Cost Saving Opportunities for Cement Making. An ENERGY STAR Guide for Energy and Plant Managers  

SciTech Connect (OSTI)

The cost of energy as part of the total production costs in the cement industry is significant, warranting attention for energy efficiency to improve the bottom line. Historically, energy intensity has declined, although more recently energy intensity seems to have stabilized with the gains. Coal and coke are currently the primary fuels for the sector, supplanting the dominance of natural gas in the 1970s. Most recently, there is a slight increase in the use of waste fuels, including tires. Between 1970 and 1999, primary physical energy intensity for cement production dropped 1 percent/year from 7.3 MBtu/short ton to 5.3 MBtu/short ton. Carbon dioxide intensity due to fuel consumption and raw material calcination dropped 16 percent, from 609 lb. C/ton of cement (0.31 tC/tonne) to 510 lb. C/ton cement (0.26 tC/tonne). Despite the historic progress, there is ample room for energy efficiency improvement. The relatively high share of wet-process plants (25 percent of clinker production in 1999 in the U.S.) suggests the existence of a considerable potential, when compared to other industrialized countries. We examined over 40 energy efficient technologies and measures and estimated energy savings, carbon dioxide savings, investment costs, and operation and maintenance costs for each of the measures. The report describes the measures and experiences of cement plants around the wold with these practices and technologies. Substantial potential for energy efficiency improvement exists in the cement industry and in individual plants. A portion of this potential will be achieved as part of (natural) modernization and expansion of existing facilities, as well as construction of new plants in particular regions. Still, a relatively large potential for improved energy management practices exists.

Low Cost, High Efficiency, High Pressure Hydrogen Storage  

SciTech Connect (OSTI)

A technical and design evaluation was carried out to meet DOE hydrogen fuel targets for 2010. These targets consisted of a system gravimetric capacity of 2.0 kWh/kg, a system volumetric capacity of 1.5 kWh/L and a system cost of $4/kWh. In compressed hydrogen storage systems, the vast majority of the weight and volume is associated with the hydrogen storage tank. In order to meet gravimetric targets for compressed hydrogen tanks, 10,000 psi carbon resin composites were used to provide the high strength required as well as low weight. For the 10,000 psi tanks, carbon fiber is the largest portion of their cost. Quantum Technologies is a tier one hydrogen system supplier for automotive companies around the world. Over the course of the program Quantum focused on development of technology to allow the compressed hydrogen storage tank to meet DOE goals. At the start of the program in 2004 Quantum was supplying systems with a specific energy of 1.1-1.6 kWh/kg, a volumetric capacity of 1.3 kWh/L and a cost of $73/kWh. Based on the inequities between DOE targets and Quantum’s then current capabilities, focus was placed first on cost reduction and second on weight reduction. Both of these were to be accomplished without reduction of the fuel system’s performance or reliability. Three distinct areas were investigated; optimization of composite structures, development of “smart tanks” that could monitor health of tank thus allowing for lower design safety factor, and the development of “Cool Fuel” technology to allow higher density gas to be stored, thus allowing smaller/lower pressure tanks that would hold the required fuel supply. The second phase of the project deals with three additional distinct tasks focusing on composite structure optimization, liner optimization, and metal.

Energy-efficient evaporators can cut operating costs for wastewater treatment, reuse  

SciTech Connect (OSTI)

High-efficiency evaporators can substantially lower the costs of recycling water, separating and reducing waste, and reclaiming industrial byproducts. Although capital costs run higher than conventional, stream-driven systems, energy efficient designs can allow users to recoup those costs over time and provide significant, ongoing utility savings. This is especially true in applications in which evaporation requirements are more than 75,000 pounds per hour, and steam costs exceed $3 per 1,000 pounds. In conventional, multistage evaporators, vapor resulting from wastewater evaporation is reused as a heating agent to effect further evaporation, but fresh steam must be added continuously to the system to maintain adequate temperature and pressure--two factors critical to evaporation. In contrast, three energy-efficient designs maintain temperature and pressure by recycling otherwise wasted resources, thereby greatly reducing or eliminating steam costs and other utility expenses.

This strategy will require a long-term commitment of a moderate increase in staff and dollars allocated to these programs. In an attempt to assess the direction BPA has taken in its OM R programs, a utility comparison team was assembled in early January 1989. The team included representatives from BPA's Management Analysis, Internal Audit and Financial Management organizations, and operation and maintenance program areas. BPA selected four utilities from a field of more than 250 electric utilities in the US and Canada. The selection criteria generally pertained to size, with key factors including transformation capacity, load, gross revenue, and interstate transmission and/or marketing agreements, and their OM R programs. Information was gathered during meetings with managers and technical experts representing the four utilities. Subsequent exchanges of information also took place to verify findings. The comparison focused on: Transmission operations and maintenance program direction and emphasis; Organization, management and implementation techniques; Reliability; and Program costs. 2 figs., 21 tabs.

Energy Efficiency Improvement and Cost Saving Oportunities for the Concrete Industry  

SciTech Connect (OSTI)

The U.S. concrete industry is the main consumer of U.S.-produced cement. The manufacturing of ready mixed concrete accounts for more than 75% of the U.S. concrete production following the manufacturing of precast concrete and masonry units. The most significant expenditure is the cost of materials accounting for more than 50% of total concrete production costs - cement only accounts for nearly 24%. In 2009, energy costs of the U.S. concrete industry were over $610 million. Hence, energy efficiency improvements along with efficient use of materials without negatively affecting product quality and yield, especially in times of increased fuel and material costs, can significantly reduce production costs and increase competitiveness. The Energy Guide starts with an overview of the U.S. concrete industry’s structure and energy use, a description of the various manufacturing processes, and identification of the major energy consuming areas in the different industry segments. This is followed by a description of general and process related energy- and cost-efficiency measures applicable to the concrete industry. Specific energy and cost savings and a typical payback period are included based on literature and case studies, when available. The Energy Guide intends to provide information on cost reduction opportunities to energy and plant managers in the U.S. concrete industry. Every cost saving opportunity should be assessed carefully prior to implementation in individual plants, as the economics and the potential energy and material savings may differ.

Processes for producing low cost, high efficiency silicon solar cells  

DOE Patents [OSTI]

Processes which utilize rapid thermal processing (RTP) are provided for inexpensively producing high efficiency silicon solar cells. The RTP processes preserve minority carrier bulk lifetime {tau} and permit selective adjustment of the depth of the diffused regions, including emitter and back surface field (bsf), within the silicon substrate. In a first RTP process, an RTP step is utilized to simultaneously diffuse phosphorus and aluminum into the front and back surfaces, respectively, of a silicon substrate. Moreover, an in situ controlled cooling procedure preserves the carrier bulk lifetime {tau} and permits selective adjustment of the depth of the diffused regions. In a second RTP process, both simultaneous diffusion of the phosphorus and aluminum as well as annealing of the front and back contacts are accomplished during the RTP step. In a third RTP process, the RTP step accomplishes simultaneous diffusion of the phosphorus and aluminum, annealing of the contacts, and annealing of a double-layer antireflection/passivation coating SiN/SiO{sub x}. In a fourth RTP process, the process of applying front and back contacts is broken up into two separate respective steps, which enhances the efficiency of the cells, at a slight time expense. In a fifth RTP process, a second RTP step is utilized to fire and adhere the screen printed or evaporated contacts to the structure. 28 figs.

A Development Path to the Efficient and Cost-Effective Bulk Storage of Electrical Energy  

SciTech Connect (OSTI)

Efficient and cost-effective means for storing electrical energy is becoming an increasing need in our electricity-oriented society. For example, for electric utilities an emerging need is for distributed storage systems, that is, energy storage at substations, at solar or wind-power sites, or for load-leveling at the site of major consumers of their electricity. One of the important consequences of distributed storage for the utilities would be the reduction in transmission losses that would result from having a local source of load-leveling power. For applications such as these there are three criteria that must be satisfied by any new system that is developed to meet such needs. These criteria are: (1) high 'turn-around' efficiency, that is, high efficiency of both storing and recovering the stored energy in electrical form, (2) long service life (tens of years), with low maintenance requirements, and, (3) acceptably low capital cost. An additional requirement for these particular applications is that the system should have low enough standby losses to permit operation on a diurnal cycle, that is, storing the energy during a portion of a given day (say during sunlight hours) followed several hours later by its use during night-time hours. One answer to the spectrum of energy storage needs just outlined is the 'electromechanical battery'. The E-M battery, under development for several years at the Laboratory and elsewhere in the world, has the potential to solve the above energy storage problems in a manner superior to the electro-chemical battery in the important attributes of energy recovery efficiency, cycle lifetime, and amortized capital cost. An electromechanical battery is an energy storage module consisting of a high-speed rotor, fabricated from fiber composite, and having an integrally mounted generator/motor. The rotor operates at high speed, in vacuo, inside of a hermetically sealed enclosure, supported by a 'magnetic bearing', that is, a bearing that uses magnetic forces to support the rotor against gravity. Magnetic bearings are a virtual necessity for the E-M battery in order to achieve long service life, and to minimize frictional losses so that the battery does not lose its charge (run down) too rapidly. These considerations mitigate against the use of conventional mechanical bearings in the E-M battery for most applications. The Laboratory has pioneered the development of a new form of magnetic bearing to meet the special requirements of the E-M battery: the 'ambient-temperature passive magnetic bearing'. Simpler, and potentially much less expensive than the existing 'active' magnetic bearings (ones requiring electronic amplifiers and feedback circuits for their operation) development of the ambient-temperature passive magnetic bearing represents a technological breakthrough. Beyond its use in the E-M battery, the ambient-temperature magnetic bearing could have important applications in replacing conventional lubricated mechanical bearings in electrical machinery. Here the gains would be two-fold: reduced frictional losses, leading to higher motor efficiency, and, of equal importance, the elimination of the need for lubricants and for routine replacement of the bearings owing to mechanical wear. Thus an added benefit from a vigorous pursuit of our electromechanical battery concepts could be its impact on many other areas of industry where rotating machinery in need of improved bearings is involved. If perfected, passive magnetic bearings would seem to represent an almost ideal replacement for the mechanical bearings in many types of industrial electrical machinery. Returning to the issued of energy storage, the E-M battery itself has much to contribute in the area of improving the efficiency of stationary energy storage systems. For example, many electrical utilities utilize 'pumped hydro' energy storage systems as a means of improving the utilization of their 'base-load' power plants. That is, electrical energy is stored during off-peak hours for delivery at times of peak usage. These pumped hydro sys

Cost analyses of energy-efficient renovations of a Moscow residential district  

Science Journals Connector (OSTI)

Abstract This paper estimates the costs of adapting three different holistic energy renovation concepts both in the buildings and at the corresponding residential district in Moscow. The results represent a baseline for the decision makers when planning implementations of holistic energy renovations in Russian residential districts. In the buildings, the estimated costs included both mandatory less energy efficient repairs and suggested energy efficiency improvements. At the building level, the costs of different renovation packages varied between €125 m–2 and €200 m–2 depending on the selected renovation package. The estimated district renovation costs include both the renovation costs of the buildings and the costs of improving district energy and water infrastructure. At the district level, the costs of the main cases per inhabitant varied between €3360 and €5200. The net present values for different building and district level renovation packages for a 20-year period were also calculated using different interest rates and annual energy price growth rates. The results suggest that renovation of a district may be more feasible than renovation of individual buildings.

The Program Administrator Cost of Saved Energy for Utility Customer-Funded Energy Efficiency Programs  

SciTech Connect (OSTI)

End-use energy efficiency is increasingly being relied upon as a resource for meeting electricity and natural gas utility system needs within the United States. There is a direct connection between the maturation of energy efficiency as a resource and the need for consistent, high-quality data and reporting of efficiency program costs and impacts. To support this effort, LBNL initiated the Cost of Saved Energy Project (CSE Project) and created a Demand-Side Management (DSM) Program Impacts Database to provide a resource for policy makers, regulators, and the efficiency industry as a whole. This study is the first technical report of the LBNL CSE Project and provides an overview of the project scope, approach, and initial findings, including: • Providing a proof of concept that the program-level cost and savings data can be collected, organized, and analyzed in a systematic fashion; • Presenting initial program, sector, and portfolio level results for the program administrator CSE for a recent time period (2009-2011); and • Encouraging state and regional entities to establish common reporting definitions and formats that would make the collection and comparison of CSE data more reliable. The LBNL DSM Program Impacts Database includes the program results reported to state regulators by more than 100 program administrators in 31 states, primarily for the years 2009–2011. In total, we have compiled cost and energy savings data on more than 1,700 programs over one or more program-years for a total of more than 4,000 program-years’ worth of data, providing a rich dataset for analyses. We use the information to report costs-per-unit of electricity and natural gas savings for utility customer-funded, end-use energy efficiency programs. The program administrator CSE values are presented at national, state, and regional levels by market sector (e.g., commercial, industrial, residential) and by program type (e.g., residential whole home programs, commercial new construction, commercial/industrial custom rebate programs). In this report, the focus is on gross energy savings and the costs borne by the program administrator—including administration, payments to implementation contractors, marketing, incentives to program participants (end users) and both midstream and upstream trade allies, and evaluation costs. We collected data on net savings and costs incurred by program participants. However, there were insufficient data on participant cost contributions, and uncertainty and variability in the ways in which net savings were reported and defined across states (and program administrators).

Evaluating capital and operating cost efficiency of offshore wind farms: A DEA approach  

Science Journals Connector (OSTI)

Abstract An actual growth rate greater than 30% indicates that offshore wind is a reasonable alternative to other energy sources. The industry today is faced with the challenge of becoming competitive and thus significantly reduce the cost of electricity from offshore wind. This situation implies that the evaluation of costs incurred during development, installation and operation is one of the most pressing issues in this industry at the moment. Unfortunately, actual cost analyses suffer from less resilient input data and the application of simple methodologies. Therefore, the objective of this study was to elevate the discussion, providing stakeholders with a sophisticated methodology and representative benchmark figures. The use of Data Envelopment Analysis (DEA) allowed for plants to be modelled as entities and costs to be related to the main specifics, such as distance to shore and water depth, ensuring the necessary comparability. Moreover, a particularly reliable database was established using cost data from annual reports. Offshore wind capacity of 3.6 GW was benchmarked regarding capital and operating cost efficiency, best-practice cost frontiers were determined, and the effects of learning-by-doing and economies of scale were investigated, ensuring that this article is of significant interest for the offshore wind industry.

Cost-benefit analysis on green building energy efficiency technology application: A case in China  

Science Journals Connector (OSTI)

Abstract In order to initiate economic evaluation of green buildings and foster their development, this article conducts the cost–benefit evaluation of energy efficiency technology application (EETA) on green buildings in China. Based on the economic evaluation theory of construction project (EETCP), the authors first establishes the theoretical framework system of cost–benefit evaluation of the EETA on green buildings and then develops the analysis methods of incremental costs and quantitative calculation formula of incremental benefits of the EETA on green buildings. Using these theories and methods, this article takes the Wanke City project in China as a study case, conducts the cost–benefit empirical analysis of the EETA on green buildings, and draws the following important conclusions: (1) the incremental costs of the EETA account for a large proportion of total incremental costs of green buildings, which are more than 50% in this case; (2) the EETA on green buildings can bring incremental economic benefits, as well as environmental benefits; (3) if only consider the incremental economic benefits of the EETA on green buildings, the financial evaluation indexes show green buildings do not have market investment potential; (4) among all the factors influencing the financial evaluation results of the EETA on green buildings, power price is the most sensitive factor, followed by the unit incremental costs, and the lifetime has the smallest influence.

Volatile organic compounds, VOC`s, are about 99% removed along with a thermal efficiency of 90 to 95%. Improvements are discussed which reduce fuel costs, reduce investment cost and give better VOC removal. A method of preventing NO{sub x} formation is presented as well as a possible method for removing NO{sub x} from incoming feed gas. Regenerative fume incinerators or regenerative thermal oxidizers have 3 possible improvements. (1) Add the required fuel to the incoming gas to nearly eliminate NO{sub x} generation while improving thermal efficiency. (2) Remove NO{sub x} from the incoming gas by a new modification of the Exxon Thermal DeNO{sub x} process. (3) Use a new 4-way valve for 1 or 2-bed regenerators to cut investment and improve destruction efficiency.

CO{sub 2} reduction potential in power production and its cost efficiency  

SciTech Connect (OSTI)

CO{sub 2} reduction potential and the economy of it in power production are handled in this presentation. The main focus is on combined heat and power production, CHP. The reference case has been the conventional coal fired condensing power plant and district heating with heavy fuel oil. Various CHP concepts are handled as substitutive technology for the reference case. Considered fuels are coal and biomass. CO{sub 2} produced in biomass firing processes is not regarded to increase the net CO{sub 2} emissions to the atmosphere. Reference case can be substituted by a more efficient coal-fired power plant, so called USC plant or by natural gas-fired combined cycle power plant. Both changes lead to very limited reduction in CO{sub 2} emissions. On the other hand the shifting is profitable. CO{sub 2} reduction potential differs in various CHP concepts according to the fuel used. With biomass the reduction is 100% and in the smallest considered coal-fired industrial power plant it is only 6%. Looking at CO{sub 2} reduction costs, ECU/t CO{sub 2}, the best alternative seems to be the changing to coal-fired CHP in industrial power plants. Due to different reduction potentials of different methods the reduction cost illustrates poorly the quality of the method. For example, in a case where the profitability is good but reduction potential is small the reduction cost is strongly negative and the case seems to be cost-effective. To avoid the previous effects the profitability of the changes has to be studied with and without CO{sub 2} emission fees. Biomass-CHP will be cost-effective compared to coal-CHP with the prices 2.5--5 ECU/t CO{sub 2} saved. The industrial CHP plant will be cost-effective despite of the fuel used and without CO{sub 2} emission fees. The district heating CHP plant will be cost-effective, if the plant size is large. The small district heating CHP plants are cost-effective, if the saved CO{sub 2} ton has a price.

The impact of ownership unbundling on cost efficiency: Empirical evidence from the New Zealand electricity distribution sector  

Science Journals Connector (OSTI)

Abstract Several countries around the world have introduced reforms to the electric power sector. One important element of these reforms is the introduction of an unbundling process, i.e., the separation of the competitive activities of supply and production from the monopole activity of transmission and distribution of electricity. There are several forms of unbundling: functional, legal and ownership. New Zealand, for instance, adopted an ownership unbundling in 1998. As discussed in the literature, ownership unbundling produces benefits and costs. One of the benefits may be an improvement in the level of the productive efficiency of the companies due to the use of the inputs in just one activity and a greater level of transparency for the regulator. This paper analyzes the cost efficiency of 28 electricity distribution companies in New Zealand for the period between 1996 and 2011. Using a stochastic frontier panel data model, a total cost function and a variable cost function are estimated in order to evaluate the impact of ownership unbundling on the level of cost efficiency. The results indicate that ownership separation of electricity generation and retail operations from the distribution network has a positive effect on the cost efficiency of distribution companies in New Zealand. The estimated effect of ownership separation suggests a positive average one-off shift in the level of cost efficiency by 0.242 in the short-run and 0.144 in the long-run.

Sensor Technology Integration for Efficient and Cost-Effective D&D  

SciTech Connect (OSTI)

The deactivation and decommissioning of radiologically contaminated facilities require the use of a multitude of technologies to perform characterization, decontamination, dismantlement, and waste management. Current baseline technologies do not provide adequate tools to perform this work in an efficient and cost-effective manner. Examples of such tasks that can be modified to enhance the D&D work include: floor and wall decontamination, pipe decontamination, and surveillance and monitoring. FIU-HCET's Technology Development, Integration and Deployment (TDID) group aims to enhance the D&D process by integrating sensor technology to existing decontamination and remote surveillance tools. These integrated systems have been demonstrated throughout the DOE Complex and commercial nuclear facilities undergoing decommissioning. Finding new ways of integrating technologies utilized in the decommissioning and surveillance & monitoring process has been a goal of this group during the past several years. Current and previous integration projects include: Mobile Integrated Piping Decontamination and Characterization System, On-Line Decontamination and Characterization System, In-Situ Pipe Decontamination and Unplugging System, Remote Hazardous Environment Surveyor (RHES), and the Online Handheld grit blasting decontamination system As a result of integrating sensors with D&D tools, the resulting technologies have removed the downtime currently found in baseline processes by allowing operators and project managers to have real-time contamination data during the specified D&D process. This added component allows project managers to verify that full decontamination and surveillance has been conducted. Through successful demonstration and deployments of the TDID-developed technologies, FIU-HCET has provided tools that can impact the cost, schedule and health and safety of D&D operations in a positive way, leading to shorter downtimes and significant cost-savings. This paper will discuss the development of technologies currently modified with sensor technology by the TDID group, from conceptual design to Deployment at a DOE or commercial nuclear facility. Cost information associated with the respective technology will also be discussed.

The CARAT program, carried out by Kinetic Art & Technology Corporation (KAT), has been one of the most commercially successful KAT R&D programs to date. Based on previous development of its technology, KAT designed, constructed and tested a highly efficient motor and controller system under this CARAT program with supplemental commercial funding. Throughout this CARAT effort, the technical objectives have been refined and refocused. Some objectives have been greatly expanded, while others have been minimized. The determining factor in all decisions to refocus the objectives was the commercial need, primarily the needs of KAT manufacturing partners. Several companies are employing the resulting CARAT motor and controller designs in prototypes for commercial products. Two of these companies have committed to providing cost share in order to facilitate the development. One of these companies is a major manufacturing company developing a revolutionary new family of products requiring the ultra-high system efficiency achievable by the KAT motor and controller technologies (known as Segmented ElectroMagnetic Array, or SEMA technology). Another company requires the high efficiency, quiet operation, and control characteristics afforded by the same basic motor and controller for an advanced air filtration product. The combined annual production requirement projected by these two companies exceeds one million units by 2005.

Cost-efficiency analysis in support of the energy conservation standards for refrigerator/freezers  

SciTech Connect (OSTI)

The National Appliance Energy Conservation At (NAECA) of 1987 requires the Department of Energy (DOE) to consider new or amended energy-efficiency standards for refrigerators and freezers along with several other appliances. This paper describes the cost-efficiency analysis of design options carried out in support of the proposed 1998 standards for refrigerator/freezers. These proposed standards are unique in that they have been reached by a consensus of various interested parties including the trade association of refrigerator and freezer manufacturers, environmental groups, state energy offices, and utility companies. In large part, these consensus standards are based on the analysis described in this paper. The analysis shows that, for example, for a 515-liter (18.2-ft{sup 3}) top-mount automatic-defrost refrigerator-freezer, the annual energy consumption can be reduced from 700 kWh/yr (2.52 GJ/yr) to 484 kWh/yr (1.74 GJ/yr) (30.9%) by the use of more efficient fan motors and compressors, improved gaskets, and insulation that is {1/2}-inch (12.7 mm) thicker. The energy use can be further reduced to 422 kWh/yr (1.52 GJ/yr) (39.8%) by employing improved heat exchangers, switching to adaptive defrost, and employing vacuum panel insulation instead of thicker walls and doors.

Low cost, single crystal-like substrates for practical, high efficiency solar cells  

SciTech Connect (OSTI)

It is well established that high efficiency (20%) solar cells can be routinely fabricated using single crystal photovoltaic (PV) materials with low defect densities. Polycrystalline materials with small grain sizes and no crystallographic texture typically result in reduced efficiences. This has been ascribed primarily to the presence of grain boundaries and their effect on recombination processes. Furthermore, lack of crystallographic texture can result in a large variation in dopant concentrations which critically control the electronic properties of the material. Hence in order to reproducibly fabricate high efficiency solar cells a method which results in near single crystal material is desirable. Bulk single crystal growth of PV materials is cumbersome, expensive and difficult to scale up. We present here a possible route to achieve this if epitaxial growth of photovoltaic materials on rolling-assisted-biaxially textured-substrates (RABiTS) can be achieved. The RABiTS process uses well-established, industrially scaleable, thermomechanical processing to produce a biaxially textured or single-crystal-like metal substrate with large grains (50-100 {mu}m). This is followed by epitaxial growth of suitable buffer layers to yield chemically and structurally compatible surfaces for epitaxial growth of device materials. Using the RABiTS process it should be possible to economically fabricate single-crystal-like substrates of desired sizes. Epitaxial growth of photovoltaic devices on such substrates presents a possible route to obtaining low-cost, high performance solar cells.

Parametric analysis of total costs and energy efficiency of 2G enzymatic ethanol production  

Science Journals Connector (OSTI)

Abstract This paper presents an analysis of total costs (TPC) and energy efficiency of enzymatic ethanol production. The analysis is parametrized with respect to plant capacity and polysaccharides content (pc) of lignocellulosic feedstock. The feedstock is based on wheat straw whose price is proportional to its pc ranging from new straw with high pc and high cost to agro-wastes with limited pc but lower cost. The plant flowsheet was built using a conventional biochemical platform with co-saccharification and fermentation (SHF) technologies. A parametric analysis of TPC as a function of plant capacity (100–2100 ton DB/day) and pc (i.e. feedstock price) (80% (75 USD/ton DB)–35% (6 USD/ton DB)) was performed with Net Present Value (NPV) techniques. Current data from Mexican economics and the agro-industrial sector were used as an illustrative case. A quasi-linear section of the TCP surface was identified delimited by (300–1100 ton DB/day) and (80–55% pc) with increments no larger than 21% of the minimum TPC obtained (0.99 USD/l etOH for 2100 ton DB/day and 80% pc). Major cost contributions are detailed and quantified for boundary cases of this surface. Energy consumption and production were also calculated for all the plant capacity and feedstock pc cases, taking into consideration the Maximum Energy Recovery (MER) obtained from a Pinch analysis. The end-use energy index eer was less than 0.82 for all cases, thus stressing the need to use process equipment with lower energy requirements. TPC are compared against previously published results for SHF technology between 500 and 2100 ton DB/day plant capacities. These values were updated and normalized with respect to feedstock and enzyme costs employed in this work. Differences among TPC and recently published normalized results are within a ±5% range, thus confirming the dependence of TPC from feedstock and enzyme prices, regardless of flowsheet technology and economic conditions.

Better Enzymes for Carbon Capture: Low-Cost Biological Catalyst to Enable Efficient Carbon Dioxide Capture  

SciTech Connect (OSTI)

IMPACCT Project: Codexis is developing new and efficient forms of enzymes known as carbonic anhydrases to absorb CO2 more rapidly and under challenging conditions found in the gas exhaust of coal-fired power plants. Carbonic anhydrases are common and are among the fastest enzymes, but they are not robust enough to withstand the harsh environment found in the power plant exhaust steams. In this project, Codexis will be using proprietary technology to improve the enzymes’ ability to withstand high temperatures and large swings in chemical composition. The project aims to develop a carbon-capture process that uses less energy and less equipment than existing approaches. This would reduce the cost of retrofitting today’s coal-fired power plants.

Process heating plays a key role in producing steel, aluminum, and glass and in manufacturing products made from these materials. Faced with regulatory and competitive pressures to control emissions and reduce operating costs, metal and glass manufacturers are considering a variety of options for reducing overall energy consumption. As 38% of the energy used in U.S. industrial plants is consumed for process heating applications, metal and glass manufacturers are discovering that process heating technologies provide significant opportunities for improving industrial productivity, energy efficiency, and global competitiveness. This fact sheet is the first in a series to describe such opportunities that can be realized in industrial systems by conducting plant-wide assessments (PWA).

Impact of the Demand-Side Management (DSM) Program structure on the cost-effectiveness of energy efficiency projects  

SciTech Connect (OSTI)

Pacific Northwest Laboratory (PNL) analyzed the cost-effective energy efficiency potential of Fort Drum, a customer of the Niagara Mohawk Power Corporation (NMPC) in Watertown, New York. Significant cost-effective investments were identified, even without any demand-side management (DSM) incentives from NMPC. Three NMPC DSM programs were then examined to determine the impact of participation on the cost-effective efficiency potential at the Fort. The following three utility programs were analyzed: (1) utility rebates to be paid back through surcharges, (2) a demand reduction program offered in conjunction with an energy services company, and (3) utility financing. Ultimately, utility rebates and financing were found to be the best programs for the Fort. This paper examines the influence that specific characteristics of the DSM programs had on the decision-making process of one customer. Fort Drum represents a significant demand-side resource, whose decisions regarding energy efficiency investments are based on life-cycle cost analysis subject to stringent capital constraints. The structures of the DSM programs offered by NMPC affect the cost-effectiveness of potential efficiency investments and the ability of the Fort to obtain sufficient capital to implement the projects. This paper compares the magnitude of the cost-effective resource available under each program, and the resulting level of energy and demand savings. The results of this analysis can be used to examine how DSM program structures impact the decision-making process of federal and large commercial customers.

Improving steam turbine efficiency  

SciTech Connect (OSTI)

This paper describes the condition of a significant number of fossil steam turbines operating in the United States and the maintenance practices used to improve their performance. Through the use of steam path audits conducted by the authors` company and by several utilities, a large data base of information on turbine heat rate, casing efficiency, and maintenance practices is available to help the power generation industry understand how different maintenance practices and steam path damage impact turbine performance. The data base reveals that turbine cycle heat rate is typically 5.23% poorer than design just prior to major outages. The degraded condition of steam turbines presents an opportunity for utilities to improve heat rate and reduce emissions without increasing fuel costs. The paper describes what losses typically contribute to the 5.23% heat rate degradation and how utilities can recover steam turbine performance through maintenance actions aimed at improving steam path efficiency.

Enery Efficient Press and Sinter of Titanium Powder for Low-Cost Components in Vehicle Applications  

SciTech Connect (OSTI)

This is the final technical report for the Department of Energy NETL project NT01931 Energy Efficient Press and Sinter of Titanium Powder for Low-Cost Components in Vehicle Applications. Titanium has been identified as one of the key materials with the required strength that can reduce the weight of automotive components and thereby reduce fuel consumption. Working with newly developed sources of titanium powder, Webster-Hoff will develop the processing technology to manufacture low cost vehicle components using the single press/single sinter techniques developed for iron based powder metallurgy today. Working with an automotive or truck manufacturer, Webster-Hoff will demonstrate the feasibility of manufacturing a press and sinter titanium component for a vehicle application. The project objective is two-fold, to develop the technology for manufacturing press and sinter titanium components, and to demonstrate the feasibility of producing a titanium component for a vehicle application. The lowest cost method for converting metal powder into a net shape part is the Powder Metallurgy Press and Sinter Process. The method involves compaction of the metal powder in a tool (usually a die and punches, upper and lower) at a high pressure (up to 60 TSI or 827 MPa) to form a green compact with the net shape of the final component. The powder in the green compact is held together by the compression bonds between the powder particles. The sinter process then converts the green compact to a metallurgically bonded net shape part through the process of solid state diffusion. The goal of this project is to expand the understanding and application of press and sinter technology to Titanium Powder applications, developing techniques to manufacture net shape Titanium components via the press and sinter process. In addition, working with a vehicle manufacturer, demonstrate the feasibility of producing a titanium component for a vehicle. This is not a research program, but rather a project to develop a process for press and sinter of net shape Titanium components. All of these project objectives have been successfully completed.

New Design Methods And Algorithms For High Energy-Efficient And Low-cost Distillation Processes  

SciTech Connect (OSTI)

This project sought and successfully answered two big challenges facing the creation of low-energy, cost-effective, zeotropic multi-component distillation processes: first, identification of an efficient search space that includes all the useful distillation configurations and no undesired configurations; second, development of an algorithm to search the space efficiently and generate an array of low-energy options for industrial multi-component mixtures. Such mixtures are found in large-scale chemical and petroleum plants. Commercialization of our results was addressed by building a user interface allowing practical application of our methods for industrial problems by anyone with basic knowledge of distillation for a given problem. We also provided our algorithm to a major U.S. Chemical Company for use by the practitioners. The successful execution of this program has provided methods and algorithms at the disposal of process engineers to readily generate low-energy solutions for a large class of multicomponent distillation problems in a typical chemical and petrochemical plant. In a petrochemical complex, the distillation trains within crude oil processing, hydrotreating units containing alkylation, isomerization, reformer, LPG (liquefied petroleum gas) and NGL (natural gas liquids) processing units can benefit from our results. Effluents from naphtha crackers and ethane-propane crackers typically contain mixtures of methane, ethylene, ethane, propylene, propane, butane and heavier hydrocarbons. We have shown that our systematic search method with a more complete search space, along with the optimization algorithm, has a potential to yield low-energy distillation configurations for all such applications with energy savings up to 50%.

Benefits and Costs of Aggressive Energy Efficiency Programs and the Impacts of Alternative Sources of Funding: Case Study of Massachusetts  

SciTech Connect (OSTI)

Increased interest by state (and federal) policymakers and regulatory agencies in pursuing aggressive energy efficiency efforts could deliver significant utility bill savings for customers while having long-term implications for ratepayers (e.g. potential rate impacts). Equity and distributional concerns associated with the authorized recovery of energy efficiency program costs may necessitate the pursuit of alternative program funding approaches. In 2008, Massachusetts passed the Green Communities Act which directed its energy efficiency (EE) program administrators to obtain all cost-effective EE resources. This goal has translated into achieving annual electric energy savings equivalent to a 2.4% reduction in retail sales from energy efficiency programs in 2012. Representatives of electricity consumer groups supported the new portfolio of EE programs (and the projected bill savings) but raised concerns about the potential rate impacts associated with achieving such aggressive EE goals, leading policymakers to seek out alternative funding sources which can potentially mitigate these effects. Utility administrators have also raised concerns about under-recovery of fixed costs when aggressive energy efficiency programs are pursued and have proposed ratemaking policies (e.g. decoupling) and business models that better align the utility's financial interests with the state's energy efficiency public policy goals. Quantifying these concerns and identifying ways they can be addressed are crucial steps in gaining the support of major stakeholder groups - lessons that can apply to other states looking to significantly increase savings targets that can be achieved from their own ratepayer-funded energy efficiency programs. We use a pro-forma utility financial model to quantify the bill and rate impacts on electricity customers when very aggressive annual energy efficiency savings goals ({approx}2.4%) are achieved over the long-term and also assess the impact of different cost recovery approaches that integrate alternative revenue sources. We also analyze alternative lost fixed cost recovery approaches to better understand how to mitigate the erosion of utility shareholder returns in states that have adopted (and achieved) very aggressive savings targets.

Developing Information on Energy Savings and Associated Costs and Benefits of Energy Efficient Emerging Technologies Applicable in California  

SciTech Connect (OSTI)

Implementation and adoption of efficient end-use technologies have proven to be one of the key measures for reducing greenhouse gas (GHG) emissions throughout the industries. In many cases, implementing energy efficiency measures is among one of the most cost effective investments that the industry could make in improving efficiency and productivity while reducing carbon dioxide (CO2) emissions. Over the years, there have been incentives to use resources and energy in a cleaner and more efficient way to create industries that are sustainable and more productive. With the working of energy programs and policies on GHG inventory and regulation, understanding and managing the costs associated with mitigation measures for GHG reductions is very important for the industry and policy makers around the world and in California. Successful implementation of applicable emerging technologies not only may help advance productivities, improve environmental impacts, or enhance industrial competitiveness, but also can play a significant role in climate-mitigation efforts by saving energy and reducing the associated GHG emissions. Developing new information on costs and savings benefits of energy efficient emerging technologies applicable in California market is important for policy makers as well as the industries. Therefore, provision of timely evaluation and estimation of the costs and energy savings potential of emerging technologies applicable to California is the focus of this report. The overall goal of the project is to identify and select a set of emerging and under-utilized energy-efficient technologies and practices as they are important to reduce energy consumption in industry while maintaining economic growth. Specifically, this report contains the results from performing Task 3 Technology Characterization for California Industries for the project titled Research Opportunities in Emerging and Under-Utilized Energy-Efficient Industrial Technologies, sponsored by California Energy Commission (CEC) and managed by California Institute for Energy and Environment (CIEE). The project purpose is to characterize energy savings, technology costs, market potential, and economic viability of newly selected technologies applicable to California. In this report, LBNL first performed technology reviews to identify new or under-utilized technologies that could offer potential in improving energy efficiency and additional benefits to California industries as well as in the U.S. industries, followed by detailed technology assessment on each targeted technology, with a focus on California applications. A total of eleven emerging or underutilized technologies applicable to California were selected and characterized with detailed information in this report. The outcomes essentially include a multi-page summary profile for each of the 11 emerging or underutilized technologies applicable to California industries, based on the formats used in the technology characterization reports (Xu et al. 2010; Martin et al. 2000).

3-Port Single-Stage PV & Battery Converter Improves Efficiency and Cost in Combined PV/Battery Systems  

SciTech Connect (OSTI)

Due to impressive cost reductions in recent years, photovoltaic (PV) generation is now able to produce electricity at highly competitive prices, but PV’s inherent intermittency reduces the potential value of this energy. The integration of battery storage with PV will be transformational by increasing the value of solar. Utility scale systems will benefit by firming intermittency including PV ramp smoothing, grid support and load shifting, allowing PV to compete directly with conventional generation. For distributed grid-tied PV adding storage will reduce peak demand utility charges, as well as providing backup power during power grid failures. The largest long term impact of combined PV and battery systems may be for delivering reliable off-grid power to the billions of individuals globally without access to conventional power grids, or for billions more that suffer from daily power outages. PV module costs no longer dominate installed PV system costs. Balance-of-System (BOS) costs including the PV inverter and installation now contribute the majority of installed system costs. Battery costs are also dropping faster than installation and battery power converter systems. In each of these separate systems power converters have become a bottleneck for efficiency, cost and reliability. These bottlenecks are compounded in hybrid power conversion systems that combine separate PV and battery converters. Hybrid power conversion systems have required multiple power converters hardware units and multiple power conversion steps adding to efficiency losses, product and installation costs, and reliability issues. Ideal Power Converters has developed and patented a completely new theory of operation for electronic power converters using its indirect EnergyPacket Switching™ topology. It has established successful power converter products for both PV and battery systems, and its 3-Port Hybrid Converter is the first product to exploit the topology’s capability for the industry’s first single-stage multi-port hybrid power converter. This unique low cost approach eliminates the hybrid power conversion bottlenecks when integrating batteries into PV systems. As result this product will significantly accelerate market adoption of these systems.

High Efficiency, Low Cost Solar Cells Manufactured Using 'Silicon Ink' on Thin Crystalline Silicon Wafers  

SciTech Connect (OSTI)

Reported are the development and demonstration of a 17% efficient 25mm x 25mm crystalline Silicon solar cell and a 16% efficient 125mm x 125mm crystalline Silicon solar cell, both produced by Ink-jet printing Silicon Ink on a thin crystalline Silicon wafer. To achieve these objectives, processing approaches were developed to print the Silicon Ink in a predetermined pattern to form a high efficiency selective emitter, remove the solvents in the Silicon Ink and fuse the deposited particle Silicon films. Additionally, standard solar cell manufacturing equipment with slightly modified processes were used to complete the fabrication of the Silicon Ink high efficiency solar cells. Also reported are the development and demonstration of a 18.5% efficient 125mm x 125mm monocrystalline Silicon cell, and a 17% efficient 125mm x 125mm multicrystalline Silicon cell, by utilizing high throughput Ink-jet and screen printing technologies. To achieve these objectives, Innovalight developed new high throughput processing tools to print and fuse both p and n type particle Silicon Inks in a predetermined pat-tern applied either on the front or the back of the cell. Additionally, a customized Ink-jet and screen printing systems, coupled with customized substrate handling solution, customized printing algorithms, and a customized ink drying process, in combination with a purchased turn-key line, were used to complete the high efficiency solar cells. This development work delivered a process capable of high volume producing 18.5% efficient crystalline Silicon solar cells and enabled the Innovalight to commercialize its technology by the summer of 2010.

Solar energy cost efficiency: a simulated case study in the Egyptian context  

Science Journals Connector (OSTI)

Electric energy coming from fossil fuels represents around 85% of total electricity requirements in Egypt. However, the supply of energy in the Arab world is expected to run dry in the coming 30-50 years. With the increase in energy needs, rise in fossil fuel prices, and swelling of greenhouse gas emissions, the use of renewable and more environment-friendly energy sources to supply power is gaining increased attention. Egypt has great potential in utilising solar energy to generate energy products and electricity. However, solar energy is still abandoned in Egypt due to its high costs. This paper examines the relative significance of several accounting and economic factors, such as depreciation schemes and financing options, in reducing solar energy costs. These factors are considered as a substitute for direct subsidies which are difficult to implement for various reasons. The results of the study provide a number of policy implications that can be applied to make solar energy closer to cost-competitiveness and contribute to solve the energy problem in Egypt.

Agency costs and efficiency of business capital investment: evidence from quarterly capital expenditures  

Science Journals Connector (OSTI)

Using the quarterly Compustat files, we present empirical findings that business capital investment is significantly higher in the fourth quarter than in other quarters. Even after controlling for business capital investment determinants, we find that the fourth quarter capital investment is significantly larger but less sensitive to investment opportunities than other quarters' capital investment. This phenomenon is more evident for firms with larger cash holdings than for firms with smaller cash holdings, for larger firms than for smaller firms, and for diversified firms than for stand-alone firms. Our findings suggest a high level of agency costs in corporate investment decisions.

Several maintenance strategies exist to prevent systems disrepair and degradation. A combination of the following can ensure an optimal blend of cost and life-cycle effectiveness: Reactive Maintenance: Follows a "run it until it breaks" strategy. No action or effort is taken to maintain equipment, prevent failure, or ensure life of the system - even if actions are suggested by the manufacturer. Preventive Maintenance: Refers to a series of actions performed on calendar time or machine run time schedules. Predictive Maintenance: Strives to detect the onset of equipment degradation and address the problems as they are identified. Several predictive maintenance technologies exist.

AISI/DOE Technology Roadmap Program: Development of Cost-effective, Energy-efficient Steel Framing  

SciTech Connect (OSTI)

Steel members in wall construction form a thermal bridge that interrupts the insulation layer of a wall. This causes higher rate of heat transfer by conduction through the wall framing than through other parts of the wall. One method to reduce the thermal bridging effect is to provide a break, such as insulating sheathing. A thermally efficient slit-web and stud was developed in this program to mitigate the conductivity of steel. The thermal performance of the slit-web stud was evaluated at Oak Ridge National Laboratory using hotbox testing. The thermal test results showed that the prototype slit-web stud performed 17% better than the solid-web stud, using R-13 fiber glass batts with exterior OSB sheathing and interior drywall. The structural behavior of this slit-web stud was evaluated in axial, bending, shear, shearwall, and stub-column tests. Test results indicated that the slitweb stud performed similarly or better than the solid-web stud in most structural performance characteristics investigated. Thus, the prototype slit-web stud has been shown to be thermally efficient, economiexecy viable, structurally sound, easily manufactured and usable in a range of residential installations.

Final Report: Development of Renewable Microbial Polyesters for Cost Effective and Energy- Efficient Wood-Plastic Composites  

SciTech Connect (OSTI)

In this project, we proposed to produce wood fiber reinforced thermoplastic composites (WFRTCs) using microbial thermoplastic polyesters in place of petroleum-derived plastic. WFRTCs are a rapidly growing product area, averaging a 38% growth rate since 1997. Their production is dependent on substantial quantities of petroleum based thermoplastics, increasing their overall energy costs by over 230% when compared to traditional Engineered Wood Products (EWP). Utilizing bio-based thermoplastics for these materials can reduce our dependence on foreign petroleum. We have demonstrated that biopolymers (polyhydroxyalkanoates, PHA) can be successfully produced from wood pulping waste streams and that viable wood fiber reinforced thermoplastic composite products can be produced from these materials. The results show that microbial polyester (PHB in this study) can be extruded together with wastewater-derived cell mass and wood flour into deck products having performance properties comparable to existing commercial HDPE/WF composite products. This study has thus proven the underlying concept that the microbial polyesters produced from waste effluents can be used to make cost-effective and energy-efficient wood-plastic composites. The cost of purified microbial polyesters is about 5-20 times that of HDPE depending on the cost of crude oil, due to high purification (40%), carbon substrate (40%) and sterilized fermentation (20%) costs for the PHB. Hence, the ability to produce competitive and functional composites with unpurified PHA-biomass mixtures from waste carbon sources in unsterile systems—without cell debris removal—is a significant step forward in producing competitive value-added structural composites from forest products residuals using a biorefinery approach. As demonstrated in the energy and waste analysis for the project, significant energy savings and waste reductions can also be realized using this approach. We recommend that the next step for development of useful products using this technology is to scale the technology from the 700-L pilot reactor to a small-scale production facility, with dedicated operation staff and engineering controls. In addition, we recommend that a market study be conducted as well as further product development for construction products that will utilize the unique properties of this bio-based material.

The gas turbine-modular helium reactor (GT-MHR), high efficiency, cost competitive, nuclear energy for the next century  

SciTech Connect (OSTI)

The Gas Turbine-Modular Helium Reactor (GT-MHR) is the result of coupling the evolution of a small passively safe reactor with key technology developments in the US during the last decade: large industrial gas turbines, large active magnetic bearings, and compact, highly effective plate-fin heat exchangers. The GT-MHR is the only reactor concept which provides a step increase in economic performance combined with increased safety. This is accomplished through its unique utilization of the Brayton cycle to produce electricity directly with the high temperature helium primary coolant from the reactor directly driving the gas turbine electrical generator. This cannot be accomplished with another reactor concept. It retains the high levels of passive safety and the standardized modular design of the steam cycle MHTGR, while showing promise for a significant reduction in power generating costs by increasing plant net efficiency to a remarkable 47%.

Low-cost electrochemical treatment of indium tin oxide anodes for high-efficiency organic light-emitting diodes  

SciTech Connect (OSTI)

We demonstrate a simple low-cost approach as an alternative to conventional O{sub 2} plasma treatment to modify the surface of indium tin oxide (ITO) anodes for use in organic light-emitting diodes. ITO is functionalized with F{sup ?} ions by electrochemical treatment in dilute hydrofluoric acid. An electrode with a work function of 5.2?eV is achieved following fluorination. Using this electrode, a maximum external quantum efficiency of 26.0% (91?cd/A, 102?lm/W) is obtained, which is 12% higher than that of a device using the O{sub 2} plasma-treated ITO. Fluorination also increases the transparency in the near-infrared region.

Structure, energy and cost efficiency evaluation of three different lightweight construction systems used in low-rise residential buildings  

Science Journals Connector (OSTI)

Abstract This article presents the analysis of the structure, energy and cost efficiency of three lightweight structural systems – wood light frames (WLF), lightweight steel frames (LGSF) and 3D sandwich (3DSP) panels – during their useful life. The structural systems focussed upon in this study are commonly used in Eastern Europe with specific reference to Turkey. The structural analysis and design was carried out using ETABS while EnergyPlus was used in the analysis of the energy consumption of the buildings. The results of the structural analysis of the three alternative construction systems show that 3DSP has better structural behaviour in terms of resistance against lateral loads. The thermal performance evaluation of the walls and ceilings shows that the WLF and LGSF walls have better insulation values (12.5% lower U-value) while the roof construction of the 3DSP has much better insulation performance (70% lower U-value). Moreover, the building designed with 3DSP requires 11% less energy for total heating and cooling during one year. The information for the building industry in Turkey shows that the cost of construction for 3DSP construction is 34.6% lower than for WLF and 27.7% lower than LGSF.

Low Cost Chemical Feedstocks Using an Improved and Energy Efficient Natural Gas Liquid (NGL) Removal Process, Final Technical Report  

SciTech Connect (OSTI)

The overall objective of this project is to develop a new low-cost and energy efficient Natural Gas Liquid (NGL) recovery process - through a combination of theoretical, bench-scale and pilot-scale testing - so that it could be offered to the natural gas industry for commercialization. The new process, known as the IROA process, is based on U.S. patent No. 6,553,784, which if commercialized, has the potential of achieving substantial energy savings compared to currently used cryogenic technology. When successfully developed, this technology will benefit the petrochemical industry, which uses NGL as feedstocks, and will also benefit other chemical industries that utilize gas-liquid separation and distillation under similar operating conditions. Specific goals and objectives of the overall program include: (i) collecting relevant physical property and Vapor Liquid Equilibrium (VLE) data for the design and evaluation of the new technology, (ii) solving critical R&D issues including the identification of suitable dehydration and NGL absorbing solvents, inhibiting corrosion, and specifying proper packing structure and materials, (iii) designing, construction and operation of bench and pilot-scale units to verify design performance, (iv) computer simulation of the process using commercial software simulation platforms such as Aspen-Plus and HYSYS, and (v) preparation of a commercialization plan and identification of industrial partners that are interested in utilizing the new technology. NGL is a collective term for C2+ hydrocarbons present in the natural gas. Historically, the commercial value of the separated NGL components has been greater than the thermal value of these liquids in the gas. The revenue derived from extracting NGLs is crucial to ensuring the overall profitability of the domestic natural gas production industry and therefore of ensuring a secure and reliable supply in the 48 contiguous states. However, rising natural gas prices have dramatically reduced the economic incentive to extract NGLs from domestically produced natural gas. Successful gas processors will be those who adopt technologies that are less energy intensive, have lower capital and operating costs and offer the flexibility to tailor the plant performance to maximize product revenue as market conditions change, while maintaining overall system efficiency. Presently, cryogenic turbo-expander technology is the dominant NGL recovery process and it is used throughout the world. This process is known to be highly energy intensive, as substantial energy is required to recompress the processed gas back to pipeline pressure. The purpose of this project is to develop a new NGL separation process that is flexible in terms of ethane rejection and can reduce energy consumption by 20-30% from current levels, particularly for ethane recoveries of less than 70%. The new process integrates the dehydration of the raw natural gas stream and the removal of NGLs in such a way that heat recovery is maximized and pressure losses are minimized so that high-value equipment such as the compressor, turbo-expander, and a separate dehydration unit are not required. GTI completed a techno-economic evaluation of the new process based on an Aspen-HYSYS simulation model. The evaluation incorporated purchased equipment cost estimates obtained from equipment suppliers and two different commercial software packages; namely, Aspen-Icarus and Preliminary Design and Quoting Service (PDQ$). For a 100 MMscfd gas processing plant, the annualized capital cost for the new technology was found to be about 10% lower than that of conventional technology for C2 recovery above 70% and about 40% lower than that of conventional technology for C2 recovery below 50%. It was also found that at around 40-50% C2 recovery (which is economically justifiable at the current natural gas prices), the energy cost to recover NGL using the new technology is about 50% of that of conventional cryogenic technology.

A comprehensive power loss, efficiency, reliability and cost calculation of a 1 MW/500 kWh battery based energy storage system for frequency regulation application  

Science Journals Connector (OSTI)

Abstract Battery based energy storage system (ESS) has tremendous diversity of application with an intense focus on frequency regulation market. An ESS typically comprised of a battery and a power conversion system. A calculation of performance parameters is performed in this research. The aim is to formulate an in-depth analysis of the ESS in terms of power losses of the semiconductor and electrical devices, efficiency, reliability and cost which would foster various research groups and industries around the globe to improve their future product. In view of this, a relation between the operating conditions and power losses is established to evaluate the efficiency of the system. The power loss calculation presented in this paper has taken into account the conduction and switching losses of the semiconductor devices. Afterwards, the Arrhenius Life Stress relation is adopted to calculate the reliability of the system by considering temperature as a covariate. And finally, a cost calculation is executed and presented as a percentage of total cost of the ESS. It has been found that the power loss and efficiency of the ESS at rated power is 146 kW and 85% respectively. Furthermore, the mean time between failures of the ESS is 8 years and reliability remains at 73% after a year. The major cost impact observed is for battery and PCS as 58% and 16% respectively. Finally, it has been determined that further research is necessary for higher efficient and lower cost system for high penetration of energy storage system in the market.

Candidate alloys for cost-effective, high-efficiency, high-temperature compact/foil heat-exchangers  

SciTech Connect (OSTI)

Solid oxide fuel cell (SOFC) and molten carbonate fuel cell (MCFC) systems operate at high temperatures (up to 1000 C and 650 C, respectively), which makes them especially attractive sources for combined heat and power (CHP) cogeneration. However, improvements in the efficiency of heat exchange in these fuel cells require both development and careful processing of advanced cost-effective alloys for use in such high-temperature service conditions. The high-temperature properties of both sheet and foil forms of several alloys being considered for use in compact heat-exchangers (recuperators) have been characterized. Mechanical and creep-rupture testing, oxidation studies, and microstructural studies have been performed on commercially available sheet and foil forms of alloy 347, alloys 625, HR230, HR120, and the new AL20-25+Nb. These studies have led to a mechanistic understanding of the responses of these alloys to anticipated service conditions, and suggest that these alloys developed for gas- and micro-turbine recuperator applications are also suitable for use in fuel cell heat-exchangers. Additional work is still required to achieve foil forms with creep life comparable to thicker-section wrought product forms of the same alloys.

Energy Efficiency Improvement and Cost Saving Opportunities for the Fruit and Vegetable Processing Industry. An ENERGY STAR Guide for Energy and Plant Managers  

SciTech Connect (OSTI)

The U.S. fruit and vegetable processing industry--defined in this Energy Guide as facilities engaged in the canning, freezing, and drying or dehydrating of fruits and vegetables--consumes over $800 million worth of purchased fuels and electricity per year. Energy efficiency improvement isan important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. fruit and vegetable processing industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. fruit and vegetable processing industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures applicable to fruit and vegetable processing plants are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in fruit and vegetable processing facilities and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. Given the importance of water in fruit and vegetable processing, a summary of basic, proven measures for improving plant-level water efficiency are also provided. The information in this Energy Guide is intended to help energy and plant managers in the U.S. fruit and vegetable processing industry reduce energy and water consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures--as well as on their applicability to different production practices--is needed to assess their cost effectiveness at individual plants.

Reducing Transaction Costs for Energy Efficiency Investments and Analysis of Economic Risk Associated With Building Performance Uncertainties: Small Buildings and Small Portfolios Program  

SciTech Connect (OSTI)

The small buildings and small portfolios (SBSP) sector face a number of barriers that inhibit SBSP owners from adopting energy efficiency solutions. This pilot project focused on overcoming two of the largest barriers to financing energy efficiency in small buildings: disproportionately high transaction costs and unknown or unacceptable risk. Solutions to these barriers can often be at odds, because inexpensive turnkey solutions are often not sufficiently tailored to the unique circumstances of each building, reducing confidence that the expected energy savings will be achieved. To address these barriers, NREL worked with two innovative, forward-thinking lead partners, Michigan Saves and Energi, to develop technical solutions that provide a quick and easy process to encourage energy efficiency investments while managing risk. The pilot project was broken into two stages: the first stage focused on reducing transaction costs, and the second stage focused on reducing performance risk. In the first stage, NREL worked with the non-profit organization, Michigan Saves, to analyze the effects of 8 energy efficiency measures (EEMs) on 81 different baseline small office building models in Holland, Michigan (climate zone 5A). The results of this analysis (totaling over 30,000 cases) are summarized in a simple spreadsheet tool that enables users to easily sort through the results and find appropriate small office EEM packages that meet a particular energy savings threshold and are likely to be cost-effective.

Reliability-based maintenance evaluations and standard preventive maintenance programs  

SciTech Connect (OSTI)

Due to recent issuance of 10CFR50.65, the U.S. Nuclear Regulatory Commission maintenance rule (Rule), and the [open quotes]Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants[close quotes] prepared by the Nuclear Management and Resources Council, many utilities are undertaking review or evaluation of current preventive maintenance (PM) programs. Although PM optimization and documentation are not specifically required by the Rule, an appropriate and effective PM program (PMP) will be the cornerstone of the successful and cost-effective implementation of the Rule. Currently, a project is being conducted at the Vermont Yankee Nuclear Power Station (VYNPS) in conjunction with Quadrex Energy Services to evaluate, optimize, and document the PMP. The project began in March 1993 and is scheduled for completion in mid-1995. The initial scope for the project is the evaluation of those structures, systems, and components that are within the scope of the Rule. Because of the number of systems to be evaluated ([approximately]50), the desired completion schedule, and cost considerations, a streamlined approach to PM optimization and documentation is being utilized.

Risk-based Multiobjective Optimization Model for Bridge Maintenance Planning  

SciTech Connect (OSTI)

Determining the optimal maintenance plan is essential for successful bridge management. The optimization objectives are defined in the forms of minimizing life-cycle cost and maximizing performance indicators. Previous bridge maintenance models assumed the process of bridge deterioration and the estimate of maintenance cost are deterministic, i.e., known with certainty. This assumption, however, is invalid especially with estimates over a long time horizon of bridge life. In this study, we consider the risks associated with bridge deterioration and maintenance cost in determining the optimal maintenance plan. The decisions variables include the strategic choice of essential maintenance (such as silane treatment and cathodic protection), and the intervals between periodic maintenance. A epsilon-constrained Particle Swarm Optimization algorithm is used to approximate the tradeoff between life-cycle cost and performance indicators. During stochastic search for optimal solutions, Monte-Carlo simulation is used to evaluate the impact of risks on the objective values, at an acceptance level of reliability. The proposed model can facilitate decision makers to select the compromised maintenance plan with a group of alternative choices, each of which leads to a different level of performance and life-cycle cost. A numerical example is used to illustrate the proposed model.

The feasibility of replacing or upgrading utility distribution transformers during routine maintenance  

SciTech Connect (OSTI)

It is estimated that electric utilities use about 40 million distribution transformers in supplying electricity to customers in the United States. Although utility distribution transformers collectively have a high average efficiency, they account for approximately 61 billion kWh of the 229 billion kWh of energy lost annually in the delivery of electricity. Distribution transformers are being replaced over time by new, more efficient, lower-loss units during routine utility maintenance of power distribution systems. Maintenance is typically not performed on units in service. However, units removed from service with appreciable remaining life are often refurbished and returned to stock. Distribution transformers may be removed from service for many reasons, including failure, over- or underloading, or line upgrades such as voltage changes or rerouting. When distribution transformers are removed from service, a decision must be made whether to dispose of the transformer and purchase a lower-loss replacement or to refurbish the transformer and return it to stock for future use. This report contains findings and recommendations on replacing utility distribution transformers during routine maintenance, which is required by section 124(c) of the Energy Policy Act of 1992. The objectives of the study are to evaluate the practicability, cost-effectiveness, and potential energy savings of replacing or upgrading existing transformers during routine utility maintenance and to develop recommendations on was to achieve the potential energy savings.

Performance and Costs of CO2 Capture at Gas Fired Power Plants  

Science Journals Connector (OSTI)

Abstract This paper summarises the results from a study that assesses the performance and costs of natural gas fired combined cycle power plants with CCS. Information is provided on the designs of each of the plants, their power output, efficiency, greenhouse gas intensity, capital costs, operating and maintenance costs, levelised costs of electricity and costs of CO2 avoidance. Discussion and commentary on the key findings and recommendations is also included. The paper includes information on base load plant performance and costs, but part load performance and costs of operation at low annual capacity factors are also presented because operation at lower load factors may be necessary, particularly in future electricity systems that include high amounts of other low-CO2 generation plants.

Advanced Maintenance Services for Promoting Sustainability  

Science Journals Connector (OSTI)

Abstract Ecology and industry, which have been many times considered as antagonists, are now associated together in the sustainability concept to support the three social / economic / environment pillars. In that way, industrial enterprises and more precisely manufacturing ones seek to integrate environment into their strategy by conducting an innovative rationalization of the production as promoted by industrial ecology and circular economy paradigms. This rationalization is favoring the evolution from product to a Product-Service Systems approach (PSS). The continuity of these services is mainly carried out by the maintenance which is no longer an aftermarket service needed for product (system) functionality but rather an inherent service function of the product (system). Thus this paper aims to investigate the role of maintenance to contribute to the development of these paradigms. It is based first on describing the main features of industrial ecology/circular economy transposing the nature concepts to industrial system. It leads to define key principles and levers to be addressed for the development of industrial ecosystems. Then maintenance activity is globally presented allowing, in a second step, to place maintenance services already existing in line with some of these principles and levers (ex. green maintenance), but also to explore advanced maintenance services more able to support promotion of industrial ecosystem by covering others principles and levers. These advanced services can be built from conventional maintenance processes but integrating sustainability goal (ex. prognostics of energy efficiency) or from innovative processes (ex. regenerative management). Finally scientific issues related to these advanced maintenance services are underlining and should concretize future research directions for researchers/practitioners working on maintenance field.

Steam driven centrifugal pump for low cost boiler feed service  

SciTech Connect (OSTI)

This article describes a steam driven centrifugal pump for boiler feed-water and other high pressure water applications, which was awarded Top Honors in the special pumps category of the 1982 Chemical processing Vaaler competition, because the simple design with turbine, pump and controls combined in an integral unit provides high operating efficiency and reliable performance with minimal maintenance. Single source responsibility for all components when the pump may have to be serviced is another advantage. These features meet the requirements for boiler feed pumps that are critical to maintaining a consistent steam supply in a process plant where downtime can be extremely expensive. The annual cost to operate the pump for 8000 hours is about $100,000, if electricity costs 5 cents/kwh. These pumps can be run for about $30,000 on steam, if natural gas costs $4.00/mcf. Cost savings are $70,000 annually.

MINLP model for optimal biocide dosing and maintenance scheduling of seawater cooled plants  

Science Journals Connector (OSTI)

Abstract Nowadays many countries in arid regions around the world suffer from severe water shortages; this situation is steadily becoming a global concern as water resources are being depleted. In this regard, strategies that a few decades ago were not feasible are becoming interesting alternatives; one of them is the use of seawater as cooling fluid in chemical plants. This alternative, however, presents problems in the plant operation, including a rapid biofilm growth (biofouling) that reduces the heat transfer efficiency. To control the biofouling, the use of biocides (usually chlorine) and periodical mechanical maintenances are implemented. In this work a mathematical programming model is presented for the optimal planning of biocide dosing and mechanical maintenance scheduling. The model considers the biocide kinetics along the network, its dependence with temperature and its interaction with the biofilm thickness. The model uses disjunctive programming to select the optimal maintenance scenario, allowing for different levels of biofilm thickness that depend on the plant schedule. The model also includes environmental constraints to prevent the discharge of streams with potentially dangerous loads of chemicals. These constraints include a limit for the concentration of biocide and the end of pipe chemical treatment. The objective function is to minimize the total annual cost, including the cost for the biocide, chemicals used for end of pipe treatment and maintenance. To show the model applicability, a case study for an integrated power/desalination plant cooled with seawater is solved. Several scenarios were tested including daily, biweekly, monthly and bimonthly biocide and end of pipe treatment chemical dosing, and mechanical maintenances from one to up to six times per year. The results indicate that recurrent dosing policies, either biweekly or monthly for operational simplicity, along with a maximum of three treatments per year provide an optimal scenario.

Highly Insulating Windows - Cost  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Cost Cost The following is an estimate of the cost effective incremental cost of highly-insulating windows (U-factor=0.20 Btu/hr-ft2-F) compared to regular ENERGY STAR windows (U-factor 0.35 Btu/hr-ft2-F). Energy savings from lower U-factors were simulated with RESFEN over an assumed useful window life of 25 years. To determine the maximum incremental cost at which highly-insulating windows would still be cost-effective, we used a formula used by many utility companies to calculate the cost of saved energy from energy efficiency programs, based on the programs' cost and savings. We turned this formula around so that the cost of saved energy equals the present energy prices in the studied locations, whereas the program cost (the incremental cost of the windows) is the dependent variable. By entering 5%

Maintenance strategies to improve sootblower availability  

SciTech Connect (OSTI)

Sootblowers are electromechanical devices used for removal of ash and slag deposits from boiler tube surfaces. By directing steam, air, or water cleaning medium through a nozzle to remove deposits from boiler tubes, boilers are kept on-line for longer periods of time reducing the need for outages to clean the boiler by mechanical means. Fuel must be burned efficiently to minimize stagging and fouling of the heat transfer surfaces. Tuning the boiler to maximize combustion efficiency should not be limited to optimizing fuel conditions, air-fuel ratios, firing rates, excess air, and over-fire air, but should also include the use of sootblowers. The goal is to know when to clean, and if the cleaning cycle has effectively removed the deposit and increased heat transfer. Today, boiler cleaning technology not only focuses on the impact of the sootblowing system on overall boiler performance, but it also focuses on design improvements that impact an individual sootblower`s performance. Proper sootblower maintenance is an integral part of making existing designs and new designs work. Existing computer technologies provide a viable means of documenting and trending sootblower performance data and maintenance history. The personal computer and the availability of spreadsheet and database software make the task of quantifying sootblower performance data and maintenance history easier to achieve. The difficult task is gathering the proper data to make decisions about sootblowing operations and maintenance. The balance of this paper will discuss typical maintenance practices, and improvements that can be achieved by documenting sootblowing system inspections and maintenance activity using a personal computer database.

Optimum maintenance strategy under uncertainty in the lifetime distribution  

Science Journals Connector (OSTI)

Abstract The problem of determining the optimal maintenance strategy for a machine given its lifetime distribution has been studied extensively. Solutions to this problem are outlined in the academic literature, prescribed in professional handbooks, implemented in reliability engineering software systems and widely used in practice. These solutions typically assume that the lifetime distribution and its parameter values are known with certainty, although this is usually not the case in practice. In this paper we study the effect of parameter uncertainty on the optimum age-based maintenance strategy. The effect of uncertainty is evaluated by considering both a theoretical uniform lifetime distribution and a more realistic Weibull lifetime distribution. The results show that admitting to the uncertainty does influence the optimal maintenance age and also provides a quantifiable cost benefit. The results can help maintenance managers in making maintenance decisions under uncertainty, and also in deciding when it is worthwhile to invest in advanced data improvement procedures.

Reactive Maintenance | Department of Energy  

Broader source: Energy.gov (indexed) [DOE]

Reactive Maintenance Reactive Maintenance Reactive Maintenance October 7, 2013 - 9:40am Addthis Reactive maintenance follows a run-it-until-it-breaks strategy where no actions or efforts are taken to maintain equipment as intended by the manufacturer. Studies indicate this is still the predominant mode of maintenance for Federal facilities. Advantages Reactive maintenance advantages are a double-edged sword. Federal agencies following a purely reactive maintenance strategy can expect little expenditures for manpower or system upkeep until something breaks. However, systems do break. With new equipment, Federal agencies can expect minimal incidents of failure. However, older equipment often experiences higher failure incidents and costlier repairs. Other advantages of reactive maintenance are:

These actions are based on either calendar time or machine run time. Advantages Federal agencies can greatly extend equipment reliability and lifespan by expending the necessary resources for regular maintenance. In most cases, the system designer or manufacturer outlines regular maintenance under a preventive strategy. In addition to increased reliability and lifespan, budget is saved over the life of the system. Preventive maintenance programs can save as much as 12% to 18% in equipment repair and replacement. Other advantages of preventitive maintenance are:

Cost effective lighting  

SciTech Connect (OSTI)

Long-life replacement lamps for the incandescent lamp have been evaluated with regard to their cost effectiveness. The replacements include the use of energy buttons that extend lamp life as well as an adaptive fluorescent circline lamp that will fit into existing incandescent lamp sockets. The initial, operating, and replacement costs for one million lumen-hours are determined for each lamp system. We find the most important lighting cost component is the operating cost. Using lamps that are less efficient or devices that cause lamps to operate less efficiently are not cost-effective. The adaptive fluorescent circline lamp, even at an initial cost of $15.00, is the most cost effective source of illumination compared to the incandescent lamp and lamp systems examined. 3 refs., 6 tabs.

Care and Maintenance of the Prairie Parcel Care and Maintenance of the Prairie Parcel Now that your prairie parcel is up and growing, there are just a few concerns that you should consider about its care. Weeding The question of weeding is really just a matter of aesthetics. You do not have to weed your parcel. If your parcel is a large one, weeding may not even be practical. Although the "weed" species will dominate your parcel for the first few years, they will give way to the native plant species. You can liken the native plants to long distance runners; they appear to start off slowly, but end up winning the ecological race. After all, they are the plants that are genetically-suited and adapted to growing in this environment. The native prairie plants will be developing extensive root structure the

Reliability centered maintenance (RCM) for substations project overview  

SciTech Connect (OSTI)

An EPRI Tailored Collaboration project establishing guidelines and tools for implementing Reliability Centered Maintenance (RCM) in substations is nearing completion and final results are being presented at this Substation RCM Conference. The ultimate goal of this RCM project is to help utilities slash substation operations and maintenance costs by optimizing equipment maintenance intervals. Preventive maintenance (PM) programs typically have been developed on a component-by-component basis, relying heavily on equipment vendors` maintenance recommendations. RCM is a logical alternative to traditional PM programs. It is intelligent, common sense maintenance that is function-based rather than component-based. First developed by the airline industry in the 1960s and further developed and applied to the nuclear industry by EPRI in the 1980s, RCM ranks the importance of each function of a system, calculates the impact the loss of the function would have on the overall system, and drives the design of appropriate maintenance tasks for each function. The nuclear industry reaped savings of at least 25% by adopting RCM, and one utility that tried this approach for substation maintenance reported savings of 13% in one year.

Ocean Thermal Energy Conversion Life Cycle Cost Assessment, Final Technical Report, 30 May 2012  

SciTech Connect (OSTI)

The Ocean Thermal Energy Conversion (OTEC) Life Cycle Cost Assessment (OLCCA) is a study performed by members of the Lockheed Martin (LM) OTEC Team under funding from the Department of Energy (DOE), Award No. DE-EE0002663, dated 01/01/2010. OLCCA objectives are to estimate procurement, operations and maintenance, and overhaul costs for two types of OTEC plants: -Plants moored to the sea floor where the electricity produced by the OTEC plant is directly connected to the grid ashore via a marine power cable (Grid Connected OTEC plants) -Open-ocean grazing OTEC plant-ships producing an energy carrier that is transported to designated ports (Energy Carrier OTEC plants) Costs are developed using the concept of levelized cost of energy established by DOE for use in comparing electricity costs from various generating systems. One area of system costs that had not been developed in detail prior to this analysis was the operations and sustainment (O&S) cost for both types of OTEC plants. Procurement costs, generally referred to as capital expense and O&S costs (operations and maintenance (O&M) costs plus overhaul and replacement costs), are assessed over the 30 year operational life of the plants and an annual annuity calculated to achieve a levelized cost (constant across entire plant life). Dividing this levelized cost by the average annual energy production results in a levelized cost of electricity, or LCOE, for the OTEC plants. Technical and production efficiency enhancements that could result in a lower value of the OTEC LCOE were also explored. The thermal OTEC resource for Oahu, Hawai�¢����i and projected build out plan were developed. The estimate of the OTEC resource and LCOE values for the planned OTEC systems enable this information to be displayed as energy supplied versus levelized cost of the supplied energy; this curve is referred to as an Energy Supply Curve. The Oahu Energy Supply Curve represents initial OTEC deployment starting in 2018 and demonstrates the predicted economies of scale as technology and efficiency improvements are realized and larger more economical plants deployed. Utilizing global high resolution OTEC resource assessment from the Ocean Thermal Extractable Energy Visualization (OTEEV) project (an independent DOE project), Global Energy Supply Curves were generated for Grid Connected and Energy Carrier OTEC plants deployed in 2045 when the predicted technology and efficiencies improvements are fully realized. The Global Energy Supply Curves present the LCOE versus capacity in ascending order with the richest, lowest cost resource locations being harvested first. These curves demonstrate the vast ocean thermal resource and potential OTEC capacity that can be harvested with little change in LCOE.

Cost analysis guidelines  

SciTech Connect (OSTI)

The first phase of the Depleted Uranium Hexafluoride Management Program (Program)--management strategy selection--consists of several program elements: Technology Assessment, Engineering Analysis, Cost Analysis, and preparation of an Environmental Impact Statement (EIS). Cost Analysis will estimate the life-cycle costs associated with each of the long-term management strategy alternatives for depleted uranium hexafluoride (UF6). The scope of Cost Analysis will include all major expenditures, from the planning and design stages through decontamination and decommissioning. The costs will be estimated at a scoping or preconceptual design level and are intended to assist decision makers in comparing alternatives for further consideration. They will not be absolute costs or bid-document costs. The purpose of the Cost Analysis Guidelines is to establish a consistent approach to analyzing of cost alternatives for managing Department of Energy`s (DOE`s) stocks of depleted uranium hexafluoride (DUF6). The component modules that make up the DUF6 management program differ substantially in operational maintenance, process-options, requirements for R and D, equipment, facilities, regulatory compliance, (O and M), and operations risk. To facilitate a consistent and equitable comparison of costs, the guidelines offer common definitions, assumptions or basis, and limitations integrated with a standard approach to the analysis. Further, the goal is to evaluate total net life-cycle costs and display them in a way that gives DOE the capability to evaluate a variety of overall DUF6 management strategies, including commercial potential. The cost estimates reflect the preconceptual level of the designs. They will be appropriate for distinguishing among management strategies.

Kalispell Maintenance Headquarters Project : Environmental Assessment.  

SciTech Connect (OSTI)

The facilities needed to maintain and repair Bonneville Power Administration (BPA's) electrical equipment in northwest Montana are currently in two locations: A maintenance headquarters at the Kalispell Substation, and a temporary leased facility south of Kalispell. The present situation is not efficient. There is not enough space to accommodate the equipment needed at each site, and coordination and communication between the two sites is difficult. Also, two sites means duplication of equipment and facilities. BPA needs a single, centralized facility that would efficiently accommodate all the area's maintenance activities and equipment. BPA proposes to build a maintenance headquarters facility consisting of 2 to 4 single-story buildings totaling about 35,000 square feet (office spaces and workshop areas); an open-ended vehicle storage building (carport style); a fenced-in storage year; a storage building for flammables, herbicides, and hazardous wastes; and a parking lot. The facility would require developing about 6 to 10 acres of land. Two sites are being considered for the proposed project (see the attached map for locations). This report is the environmental assessment of the two options.

Geothermal power plant R and D: an analysis of cost-performance tradeoffs and the Heber Binary-Cycle Demonstration Project  

SciTech Connect (OSTI)

A study of advancements in power plant designs for use at geothermal resources in the low to moderate (300 to 400F) temperature range is reported. In 3 case studies, the benefits of R and D to achieve these advancements are evaluated in terms of expected increases in installed geothermal generating capacity over the next 2 decades. A parametric sensitivity study is discussed which analyzes differential power development for combinations of power plant efficiency and capitol cost. Affordable tradeoffs between plant performance and capital costs are illustrated. The independent review and analysis of the expected costs of construction, operation and maintenance of the Heber Binary Cycle Geothermal Power Demonstration Plant are described. Included in this assessment is an analysis of each of the major cost components of the project, including (1) construction cost, (2) well field development costs, (3) fluid purchase costs, and (4) well field and power plant operation and maintenance costs. The total cost of power generated from the Heber Plant (in terms of mills per kWh) is then compared to the cost of power from alternative fossil-fueled base load units. Also evaluated are the provisions of both: (a) the Cooperative Agreement between the federal government and San Diego Gas and Electric (SDG and E); and (b) the Geothermal Heat Sales Contract with Union Oil Company.

Steam turbine path evaluation during maintenance  

SciTech Connect (OSTI)

The deterioration of a turbine (Steam & Gas) flow path affects the efficiency of the turbine. The most critical factors which affect the efficiency of turbines are: wearing out of the trailing edges of the blades by solid particle erosion, deposits, material loss due to corrosion (also sand blast) which increases the flow area, increases in blade surface roughness, etc. Wearing out of the seals caused by shaft vibrations or rapid start-up leads to significant leakage losses. Some of these effects can be estimated with some precision during operation of the turbine, but an exact evaluation can be carried out during a maintenance applying a special fluid flow analysis program. Such a program has been developed and then adapted to achieve this goal. During maintenance the complete geometry of the steam path is measured (blades lengths, widths, angles, clearances, etc.) in the condition encountered before any corrections. Then the similar measurement is undertaken after, for example, clearance corrections, blade replacements, cleaning of the blades, etc. Using the program first of all the design data is calculated. Then the actual data is fed into the program and compared to the design data. Thus the effect of the blade surface roughness, increased seal clearances, flow area increase, solid particle damage to the trailing edge and so on for each particular stage is calculated. The effect is expressed in [kW] as a deviation from the design points. This data can be helpful during online evaluation of the turbine performance. This evaluation helps the management of the plant in undertaking the correct decision concerning the date of the next major maintenance and replacement part procurement. Many turbines in the Mexican utility have been evaluated in such a manner. Some examples are presented.

Considerations for efficient airflow design in cleanrooms  

SciTech Connect (OSTI)

A high-performance cleanroom should provide efficient energy performance in addition to effective contamination control. Energy-efficient designs can yield capital and operational cost savings, and can be part of a strategy to improve productivity in the cleanroom industry. Based upon in-situ measurement data from ISO Class 5 clean rooms, this article discusses key factors affecting cleanroom air system performance and benefits of efficient airflow design in clean rooms. Cleanroom HVAC systems used in the semiconductor, pharmaceutical, and healthcare industries are very energy intensive, requiring large volumes of cleaned air to remove or dilute contaminants for satisfactory operations. There is a tendency, however, to design excessive airflow rates into cleanroom HVAC systems, due to factors such as design conservatism, lack of thorough understanding of airflow requirements, concerns about cleanliness reliability, and potential design and operational liabilities. Energy use of cleanroom environmental systems varies with system type and design, cleanroom functions, and the control of critical parameters such as temperature and humidity. In particular, cleanroom cleanliness requirements specified by cleanliness class have an impact on overall energy use. A previous study covering Europe and the US reveals annual cleanroom electricity usage for cooling and fan energy varies significantly depending on cleanliness class, and may account for up to three-quarters of total annual operating costs. A study on a semiconductor cleanroom in Japan found air delivery systems account for more than 30% of total power consumption. It is evident that the main factors dictating cleanroom operation energy include airflow rates and HVAC system efficiency. Improving energy efficiency in clean rooms may potentially contribute to significant savings in the initial costs of the facilities as well as operation and maintenance costs. For example, energy consumption by a typical chip manufacturer can be cut 40% or more, and the associated greenhouse emissions even more. Cleanroom HVAC systems provide huge opportunities for energy savings in the semiconductor industry. In addition to direct cost reductions in cleanroom investment and operation, energy-efficient designs can reduce maintenance costs, increase power reliability, improve time-to-market in cleanroom production, and improve environmental quality. Companies that use energy efficiency to lower costs and increase productivity can gain a competitive advantage and achieve a higher return on investment. In addition, energy-efficient cleanroom systems conserve energy and natural resources, heightening the company's reputation as an environmentally conscious leader in the community and the industry. A significant portion of energy use in cleanroom environmental systems is associated with recirculating air systems. We will review and analyze design factors and operational performance of airflow systems in ISO Class 5 clean rooms. We will also discuss benefits of efficient cleanroom airflow designs in conjunction with effective cleanroom contamination control. We will consider the following common recirculating air system designs: fan-tower (FT) with pressurized-plenum; distributed air handler unit (AHU); and fan-filter unit (FFU).

Industrial heat pumps - types and costs  

SciTech Connect (OSTI)

Confusion about energy savings and economics is preventing many potentially beneficial applications for industrial heat pumps. The variety of heat pumps available and the lack of a standard rating system cause some of this confusion. The authors illustrate how a simple categorization based on coefficient of performance (COP) can compare the cost of recovering waste energy with heat pumps. After evaluating examples in which the cost of energy delivered was calculated based on estimates of capital cost, operating costs, and maintenance costs, they compare heat pumps from the various categories on the basis of economics. 6 references, 6 figures, 1 table.

Decommissioning Unit Cost Data  

SciTech Connect (OSTI)

The Rocky Flats Closure Site (Site) is in the process of stabilizing residual nuclear materials, decommissioning nuclear facilities, and remediating environmental media. A number of contaminated facilities have been decommissioned, including one building, Building 779, that contained gloveboxes used for plutonium process development but did little actual plutonium processing. The actual costs incurred to decommission this facility formed much of the basis or standards used to estimate the decommissioning of the remaining plutonium-processing buildings. Recent decommissioning activities in the first actual production facility, Building 771, implemented a number of process and procedural improvements. These include methods for handling plutonium contaminated equipment, including size reduction, decontamination, and waste packaging, as well as management improvements to streamline planning and work control. These improvements resulted in a safer working environment and reduced project cost, as demonstrated in the overall project efficiency. The topic of this paper is the analysis of how this improved efficiency is reflected in recent unit costs for activities specific to the decommissioning of plutonium facilities. This analysis will allow the Site to quantify the impacts on future Rocky Flats decommissioning activities, and to develop data for planning and cost estimating the decommissioning of future facilities. The paper discusses the methods used to collect and arrange the project data from the individual work areas within Building 771. Regression and data correlation techniques were used to quantify values for different types of decommissioning activities. The discussion includes the approach to identify and allocate overall project support, waste management, and Site support costs based on the overall Site and project costs to provide a ''burdened'' unit cost. The paper ultimately provides a unit cost basis that can be used to support cost estimates for decommissioning at other facilities with similar equipment and labor costs. It also provides techniques for extracting information from limited data using extrapolation and interpolation techniques.

Cost Shifting  

Science Journals Connector (OSTI)

Abstract Cost shifting exists when a provider raises prices for one set of buyers because it has lowered prices for some other buyer. In theory, cost shifting can take place only if providers have unexploited market power. The empirical evidence on the extent of cost shifting is mixed. Taken as a whole, the evidence does not support the claims that cost shifting is a large and pervasive feature of the US health-care markets. At most, one can argue that perhaps one-fifth of Medicare payment reductions have been passed on to private payers. The majority of the rigorous studies, however, have found no evidence of cost shifting.

Energy cost reduction in the synchronization of a pair of nonidentical coupled Hindmarsh-Rose neurons  

E-Print Network [OSTI]

Many biological processes involve synchronization between nonequivalent systems, i.e, systems where the difference is limited to a rather small parameter mismatch. The maintenance of the synchronized regime in this cases is energetically costly \\cite{1}. This work studies the energy implications of synchronization phenomena in a pair of structurally flexible coupled neurons that interact through electrical coupling. We show that the forced synchronization between two nonidentical neurons creates appropriate conditions for an efficient actuation of adaptive laws able to make the neurons structurally approach their behaviours in order to decrease the flow of energy required to maintain the synchronization regime.

Risk-based decision making method for maintenance policy selection of thermal power plant equipment  

Science Journals Connector (OSTI)

This study presents a decision-making method for maintenance policy selection of power plants equipment. The method is based on risk analysis concepts. The method first step consists in identifying critical equipment both for power plant operational performance and availability based on risk concepts. The second step involves the proposal of a potential maintenance policy that could be applied to critical equipment in order to increase its availability. The costs associated with each potential maintenance policy must be estimated, including the maintenance costs and the cost of failure that measures the critical equipment failure consequences for the power plant operation. Once the failure probabilities and the costs of failures are estimated, a decision-making procedure is applied to select the best maintenance policy. The decision criterion is to minimize the equipment cost of failure, considering the costs and likelihood of occurrence of failure scenarios. The method is applied to the analysis of a lubrication oil system used in gas turbines journal bearings. The turbine has more than 150 MW nominal output, installed in an open cycle thermoelectric power plant. A design modification with the installation of a redundant oil pump is proposed for lubricating oil system availability improvement.

Science Journals Connector (OSTI)

Aiming at the risk aversion of adverse selection and efficiency improvement in maintenance ally searching, relation web and Mobile Agent are introduced into the study of maintenance ally searching. A maintenance ally searching method based on relation web model is proposed. First, the method decomposes complicated plant maintenance tasks, and then by setting up ally Searching Sub-Agent, the relation web model is mapped as properties, plans, behaviours and interactions of the Searching Sub-Agent. Based on the relation categories, shortest path, reliability and other definitions in relation to web model, a quantified evaluation method for acquaintance reliability and capability in maintenance alliance and ally searching strategy are designed. A solution for recommendation deadlock and dynamic management of Searching Sub-Agent is discussed. The ally searching system in maintenance alliance based on the above method is effectively applied in a plant overhaul of a partner petrochemical company.

Public release of optimization of metallization scheme for thin emitter wrap-through solar cells for higher efficiency, reduced precious metal costs, and reduced stress.  

SciTech Connect (OSTI)

Back-contact crystalline-silicon photovoltaic solar cells and modules offer a number of advantages, including the elimination of grid shadowing losses, reduced cost through use of thinner silicon substrates, simpler module assembly, and improved aesthetics. While the existing edge tab method for interconnecting and stringing edge-connected back contact cells is acceptably straightforward and reliable, there are further gains to be exploited when you have both contact polarities on one side of the cell. In this work, we produce 'busbarless' emitter wrap-through solar cells that use 41% of the gridline silver (Ag) metallization mass compared to the edge tab design. Further, series resistance power losses are reduced by extraction of current from more places on the cell rear, leading to a fill factor improvement of about 6% (relative) on the module level. Series resistance and current-generation losses associated with large rear bondpads and busbars are eliminated. Use of thin silicon (Si) wafers is enabled because of the reduced Ag metallization mass and by interconnection with conductive adhesives leading to reduced bow. The busbarless cell design interconnected with conductive adhesives passes typical International Electrotechnical Commission damp heat and thermal cycling test.

Efficient Phase-Change Materials: Development of a Low-Cost Thermal Energy Storage System Using Phase-Change Materials with Enhanced Radiation Heat Transfer  

SciTech Connect (OSTI)

HEATS Project: USF is developing low-cost, high-temperature phase-change materials (PCMs) for use in thermal energy storage systems. Heat storage materials are critical to the energy storage process. In solar thermal storage systems, heat can be stored in these materials during the day and released at night—when the sun is not out—to drive a turbine and produce electricity. In nuclear storage systems, heat can be stored in these materials at night and released to produce electricity during daytime peak-demand hours. Most PCMs do not conduct heat very well. Using an innovative, electroless encapsulation technique, USF is enhancing the heat transfer capability of its PCMs. The inner walls of the capsules will be lined with a corrosion-resistant, high-infrared emissivity coating, and the absorptivity of the PCM will be controlled with the addition of nano-sized particles. USF’s PCMs remain stable at temperatures from 600 to 1,000°C and can be used for solar thermal power storage, nuclear thermal power storage, and other applications.

Efficiently generate steam from cogeneration plants  

SciTech Connect (OSTI)

As cogeneration gets more popular, some plants have two choices of equipment for generating steam. Plant engineers need to have a decision chart to split the duty efficiently between (oil-fired or gas-fired) steam generators (SGs) and heat recovery steam generators (HRSGs) using the exhaust from gas turbines. Underlying the dilemma is that the load-versus-efficiency characteristics of both types of equipment are different. When the limitations of each type of equipment and its capability are considered, analysis can come up with several selection possibilities. It is almost always more efficient to generate steam in an HRSG (designed for firing) as compared with conventional steam generators. However, other aspects, such as maintenance, availability of personnel, equipment limitations and operating costs, should also be considered before making a final decision. Loading each type of equipment differently also affects the overall efficiency or the fuel consumption. This article describes the performance aspects of representative steam generators and gas turbine HRSGs and suggests how plant engineers can generate steam efficiently. It also illustrates how to construct a decision chart for a typical installation. The equipment was picked arbitrarily to show the method. The natural gas fired steam generator has a maximum capacity of 100,000 lb/h, 400-psig saturated steam, and the gas-turbine-exhaust HRSG has the same capacity. It is designed for supplementary firing with natural gas.

High power vented nickel-cadmium cells designed for ultra low maintenance  

SciTech Connect (OSTI)

Initially the SAFT program to develop maintenance-free battery technology was in response to a U.S. Air Force commitment to eliminate the need for battery maintenance shops at the line level. The U.S. Navy, through its Crane, Indiana Battery Test Facility, added further demands. They wanted new nickel cadmium battery designs that were lighter, had greater power, more capacity, required much less maintenance, and still met standard Military Specification size requirements. Crane personnel recognized that the major savings in the maintenance costs were achievable in 3- to 5-fold increases of the maintenance period and that non-maintainability was not necessarily a design requisite. In response, SAFT established an internally funded program whose objective was the development of a battery technology that would provide military aircraft batteries meeting these demands.

Maintenance and repair expenditures: determinants and tradeoffs with new capital goods  

Science Journals Connector (OSTI)

Traditionally economic analysis has focused on new capital investment, while ignoring expenditures to maintain or repair existing stock. Recent, broader theories of replacement have emphasized the important role played by both maintenance and utilization rates. However, the decision to extend the service life of capital has been given scant empirical attention, owing partly to a lack of appropriate data. This study exploits survey data that report annual maintenance/repair expenditures for Canadian manufacturing industries. A standard production framework, modified to incorporate endogenous depreciation, guides the econometric analysis. The empirical results indicate that the cost of capital, among other variables, has a statistically significant effect on maintenance/repair decisions.

Economic and sensitivity analyses of dynamic distributed generation dispatch to reduce building energy cost  

Science Journals Connector (OSTI)

Abstract The practicality of any particular distributed generation (DG) installation depends upon its ability to reduce overall energy costs. A parametric study summarizing DG performance capabilities is developed using an economic dispatch strategy that minimizes building energy costs. Various electric rate structures are considered and applied to simulate meeting various measured building demand dynamics for heat and power. A determination of whether investment in DG makes economic sense is developed using a real-time dynamic dispatch and control strategy to meet real building demand dynamics. Under the economic dispatch strategy, capacity factor is influenced by DG electrical efficiency, operations and maintenance cost, and fuel price. Under a declining block natural gas rate structure, a large local thermal demand improves DG economics. Increasing capacity for DG that produces low cost electricity increases savings, but installing further capacity beyond the average building electrical demand reduces savings. For DG that produces high cost electricity, reducing demand charges can produce savings. Heat recovery improves capacity factor and DG economics only if thermal and electrical demand is coincident and DG heat is utilized. Potential DG economic value can be improved or impaired depending upon how the utility electricity cost is determined.

On risk-based operation and maintenance of offshore wind turbine components  

Science Journals Connector (OSTI)

Operation and maintenance are significant contributors to the cost of energy for offshore wind turbines. Optimal planning could rationally be based on Bayesian pre-posterior decision theory, and all costs through the lifetime of the structures should be included. This paper contains a study of a generic case where the costs are evaluated for a single wind turbine with a single component. Costs due to inspections, repairs, and lost production are included in the model. The costs are compared for two distinct maintenance strategies, namely with and without inclusion of periodic imperfect inspections. Finally the influence of different important parameters, e.g. failure rate, reliability of inspections, inspection interval, and decision rule for repairs, is evaluated.

The results of this assessment were evaluated to determine needed improvements in PNL Craft Services' current maintenance program. The objective of this implementation plan is to provide baseline information for compliance to the DOE 4330.4A, and for needed improvements. The prime consideration in applying a graded approach to the Order has been to maintain safe and reliable operations, environmental compliance, safeguards and security, programmatic mission, facility preservation, and/or other facility-specific requirements. Using the results of the self-assessment, PNL has selected nine of the 18 elements of the Maintenance Program defined by DOE Order 4330.4A for improvement. The elements selected for improvement are Training and Qualification of Maintenance Personnel; Maintenance Procedures; Planning, Scheduling, and Coordination of Maintenance; Control of Maintenance Activities; Post-Maintenance Testing; Facility Condition Inspection; Management Involvement; Maintenance History; and Additional Maintenance Requirements. Based upon graded approach and current funding, those elements considered most important have been selected as goals for earliest compliance. Commitment dates for these elements have been established for compliance. The remaining elements of noncompliance will be targeted for implementation during later budget periods.
