The West Springfield 45 MW BESS is a proposed energy storage project located in Hampden County, Massachusetts. The project, with a total capacity of 45 MW, consists entirely of battery storage. It is listed in the ISO-NE interconnection queue as queue ID ISO-NE-1272, with an entry date of June 8, 2022, and a proposed commercial operation date of May 8, 2026.
The project's interconnection agreement (IA) has been executed. The point of interconnection (POI) is the West Springfield Station, 115kV Bus, utilizing the existing 8C-3X 140 MVA transformer at position WS#2. The project has appeared in recent news coverage.
