ABSTRACT:
A method and apparatus are disclosed for converting the potential energy stored in an upper reservoir of water into electrical energy, whereby, during periods of high energy demand, water is introduced from the upper reservoir into an underground salt dome by way of an underground shaft which connects the upper reservoir with the underground salt dome. Hydroelectric generators which are located along the shaft convert the kinetic energy of the falling water into electrical energy to meet periodic high energy demands. The water empties into the underground salt dome and dissolves a cavity in the same to produce a large underground reservoir. During periods of electrical energy surplus, electric pumps are utilized to pump the water back to the surface so that the process may be repeated.
