This volume documents the plant design for an underground pumped hydroelectric (UPH) storage facility having maximum generating capacity of 2000 MW and energy storage capacity of 20,000 MWh at a nominal head of 5000 ft. The UPH facility is a two step configuration with single-stage reversible pump-turbines, each step consisting of a 1000 MW plant at a nominal head of 2500 ft. The surface facilities and upper reservoir, shafts and hoists, penstocks and hydraulic tunnels, powerhouses, and intermediate and lower reservoirs are described. Details of the power plant electrical and mechanical equipment, including pump-turbine and motor-generator units, are given. The development of the site is outlined together with the construction methods and schedule. The cost estimates and a cost-risk analysis are presented. Plant operation, including unit operation, two-step operation, plant efficiency, and availability, is outlined.
