List the basic parts and a pumped storage hydroelectric dam and explain how it produces electrical power
What will be an ideal response?
A pumped storage hydroelectric dam uses two reservoirs; one is located at a much higher elevation than the other. The lower reservoir has a turbine and generator as in a conventional dam but the generator can double as a motor to pump water to the upper reservoir during low electrical peak hours. During the highest peak times, water is released from the upper reservoir to generate power.
