It utilizes the surplus electric energy in the power system to pump the water in the lower reservoir (the reservoir with a lower elevation) to the upper reservoir (the reservoir with a higher elevation) during the low load period of the power system for storage in the form of potential energy. When the system needs electricity, the water is released from the upper reservoir to the lower reservoir for power generation.
