Capacity Value of Energy Storage in PJM

Astrapé Consulting performed a capacity valuation of energy-limited resources (ELRs) using the Strategic Energy and Risk Valuation Model (SERVM) for the PJM Interconnection, L.L.C. (PJM). The intent of this analysis was to determine the duration requirements for ELRs based on their ability to provide the same reliability benefits as conventional fully-dispatchable resources. This analysis was performed using the projected and potential resource mix in PJM over the planning horizon which included aggressive energy storage deployments. Since reliability considerations are unique to the composition of the fleet in each electric system, it was critical that our analysis use an accurate representation of the current and projected PJM system.
