Title: Guide to a geothermal heat plan: a geothermal energy application. Serial No. 3

Abstract

The concept of a heat plan is introduced so that local officials may become familiar with thermal considerations and determine which options deserve further study and action. The approach for formulating a heat plan is a two-part process where heat resources and end-uses are first characterized in a heat atlas and then acted upon according to goals and strategies embodied in the plan. The purpose of the atlas is to systematically monitor a community's thermal supplies and demands, and to catalog them in the same manner as other community development sectors. The heat plan contains thermal goals and implementation measures based on conditions and opportunities revealed in the atlas. The heat demands considered in the atlas include space, water, and industrial process heat demands. Thermal resources considered include those conventional fuels already in use, as well as those alternate energy resources which have potential for utilization. (LEW)

  • General planning considerations which affect nearly every community are reviewed, and alternative operating structures which are available to communities are reviewed, including local governments, nonprofit cooperatives, private enterprises, and joint ventures. The financing options available to publicly-owned and privately-owned district heating systems are then summarized. The geothermal production and distribution activities most appropriate to each type of operating structure are reviewed, along with typical equity and debt funding sources. The tax advantages for private developers are described, as are the issures of customer contracts and service prices, and customer retrofit financing. The treatment is limited to an introductory overview. (LEW)

    A total of 82 holes ranging in depth from 18 to 400 meters were drilled for thermal and hydrologic studies in a 200 km/sup 2/ area of Grass Valley, Nevada, near Leach Hot Springs. Outside the immediate area of Leach Hot Springs, heat flow ranges from 1 to 6.5 hfu with a mean of 2.4 hfu (1 hfu = 10/sup -6/ cal cm/sup 2/ s/sup -1/ = 41.8 mWm/sup -2/). Within 2 km of the springs, conductive heat flow ranges between 1.6 and more than 70 hfu averaging 13.6 hfu. Besides the conspicuous thermal anomaly associated with the hot springs,more » two additional anomalies were identified. One is associated with faults bounding the western margin of the Tobin Range near Panther Canyon, and the other is near the middle of Grass Valley about 5 km SSW of Leach Hot Springs. The mid-valley anomaly appears to be caused by hydrothermal circulation in a bedrock horst beneath about 375 meters of impermeable valley sediments. If the convective and conductive heat discharge within 2 km of the Leach Hot Springs is averaged over the entire hydrologic system (including areas of recharge), the combined heat flux from this part of Grass Valley is about 3 hfu, consistent with the average regional conductive heat flow in the Battle Mountain High. The hydrothermal system can be interpreted as being in a stationary stable phase sustained by high regional heat flow, and no localized crustal heat sources (other than hydrothermal convection to depths of a few kilometers) need be invoked to explain the existence of Leach Hot Springs.« less

    The Applied Physics Laboratory and the Center for Metropolitan Planning and Research of The Johns Hopkins University support the Department of Energy's Division of Geothermal Energy (DOE/DGE) in planning and assisting the development of geothermal energy in the eastern United States. This effort includes development scenarios, energy market surveys, development of tools to analyze and optimize the cost of geothermal energy, the methodology for prediction of market penetration technical assistance to states, groups, and individuals and general support to DOE/DGE. This report documents one of the economic tools developed under that program. Related reports are listed as references.

  • The resource testing and data gathering involve four sequentially scheduled stages: production well drilling tests, short term production tests, injection well drilling tests, and full scale production tests. Each stage is described and discussed. (MHR)
