pumped storage

n.
A system of generating electricity with hydroelectric power, in which the electricity is generated during hours of peak consumption by using water that has been pumped into an elevated reservoir during the hours of low consumption.

pumped storage

n
(Electrical Engineering) (in hydroelectric systems) a method of using power at a period of low demand to pump water back up to a high storage reservoir so that it can be released to generate electricity at a period of peak demand
