Water for long-term geothermal enegy production in the Imperial Valley
The geothermal resources of California's Imperial Valley have the potential for the production of an estimated 3000 to 5000 MW/yr of electricity for 30 yr, provided that adeuqate cooling water is available for power plants. There are five possible sources of cooling water: irrigation water, waste waters from agriculture, steam condensate, ground water, and water from the Salton Sea. Technical, environmental, and regulatory constraints, however, could limit the availability of the water supplies. Of particular concern are the constraints that could be imposed if different water policies were implemented. To study how future policies could affect geothermal development, six combinations of various policies were defined to represent potential regulatory controls. A range of future water balances in the valley was also specified. The water balances plus the six policy combinations were used to determine whether deficits of cooling water would eventually constrain low, medium, or high levels of geothermal energy production. A companion analysis of changes in the elevation and salinity of the Salton Sea resulting from the use of agricultural waters for cooling was also made.
