High mountain dam energy storage

Pumped-Storage Hyro Plants

A flexible, dynamic, efficient and green way to store and deliver large quantities of electricity, pumped-storage hydro plants store and generate energy by moving water between two reservoirs at different elevations. During times of low electricity demand, such as at night or on weekends, excess energy is used to pump water to an upper reservoir.

Pump Up the Storage | Do the Math

So let''s take a cubic meter of water, at a mass of 1000 kg, and send it through the turbine. The mgh energy in the cube of water for a 100 m high dam is (1000 kg)(10 m/s²)(100 m) = 10 6 J, or one megajoule. If this 100 m high dam only has one cubic meter per second flowing through, it would produce 1 MJ/sec, or 1 MW.
