Potomac Electric Power Company and Acres American Incorporated have been performing a three year DOE/EPRI/PEPCO sponsored program for preliminary design of water compensated Compressed Air Energy Storage (CAES) and Underground Pumped Hydroelectric (UPH) power plants. This report presents both the costs of the CAES and UPH plant designs which were developed, and the results of economic evaluations performed for the PEPCO system. The PEPCO system planning analysis was performed in parallel stages with plant design development. Analyses performed early in the project indicated a requirement for 1000 MW/10,000 MWH of energy storage on a daily operating schedule, with economic installation in two segments of 500 MW in 1990 and 1997. The analysis was updated eighteen months later near the end of the project to reflect the impact of new growth projections and revised plant costs. The revised results indicated economic installations for either UPH or CAES of approximately 675 MW/6750 MWH on a daily cycle, installed in blocks of approximately 225 MW in 1990, 1993 and 1995. Significant savings in revenue requirements and oil fuel over the combustion turbine alternative were identified for both CAES and UPH.
