Even considering the 20%–25% energy losses due to PSH roundtrip cycle efficiency, the value of PSH energy generated during the peak period outweighs the value of energy used for pumping during the off-peak period. This is because pumping energy is typically provided by low-cost baseload units or by renewable generation.
Pumped storage hydropower (PSH) plants are a sizable part of the energy mix in the U.S., with 40 PSH plants in operation in 2015, totaling about 22 GW in installed capacity (DOE 2016) and an estimated 553 GWh of energy storage (Uria-Martinez et al. 2021).
Like every other energy storage technology, PSH is energy limited and cannot meet the requirements of every service simultaneously. There is competition for the energy in the PSH unit, with intertemporal competition being a key factor.
A pumped storage reservoir is a type of reservoir primarily used for energy storage in hydropower systems. Unlike conventional hydropower reservoirs, which often serve multiple purposes, many pumped storage reservoirs in the U.S. were developed for this primary purpose.
For example, if a pumped storage hydro unit wanted to bid into the FTR market in PJM, it has to be a PJM member or a customer to be eligible. If the unit fulfills the minimum requirements to participate in the auction market, it may register with PJM.
