Study refutes proposed PJM requirements for storage assets
Astrapé Consulting recently released a study funded by the U.S. Energy Storage Association (ESA) and National Resources Defense Council (NRDC) that rebuts arguments by PJM in a recent case regarding storage assets.
The study concludes that a PJM proposal to require storage assets to run for 10 continuous hours to qualify its full output for the capacity market is “unnecessary and unduly restrictive.”
It maintains that a shorter storage duration requirement correctly reflects its capacity value for the foreseeable future.
In February 2018, FERC issued Order 841, which requires regional electric market operators to accommodate the use of energy storage on the grid where technically feasible.
“Energy storage is being installed on electric grids across the country at a rapid pace, helping transform our electric system to a more resilient, efficient, sustainable and affordable one,” ESA CEO Kelly Speakes-Backman said. “We stand behind the leadership at FERC to modernize energy rules to enable this transition. This study clearly affirms FERC’s judgment to include a broader set of technologies to participate, saving consumers money, and supporting a diverse supply of clean energy generation.”
“Storage is a key technology enabling a low-carbon grid,” Tom Rutigliano, a senior advocate at NRDC, said. “This study agrees with many others in showing that batteries are an effective replacement for power plants. It also underscores the importance of FERC’s commitment to ensuring that rules developed for older technologies do not become barriers to storage.”
