Capacity Value of Energy Storage in PJM – Policy Brief
FERC Order 841 requires regional electric market operators to enable the use of energy storage on the grid to provide services for which it is technically capable. One of these operators, PJM, has requested a special rule that would effectively prevent a number of storage projects from market participation and is based on flawed assumptions. As part of our FERC filings, the U.S. Energy Storage Association (ESA) and National Resources Defense Council (NRDC) commissioned a study by Astrapé Consulting that provides evidence and supporting data that refutes PJM’s arguments about capacity limitations, supporting our arguments that FERC should decline PJM’s request.
