Interconnection Agreement executed with ISO-NE
The Battery Storage project (ISO-NE-1320) is a proposed 203.95 MW battery storage project located in Worcester County, Massachusetts. The project consists solely of battery storage. It is in the ISO-NE interconnection queue as of October 7, 2022, with a proposed commercial operation date of November 16, 2027.
The interconnection agreement for the project is currently in progress, with the specific study being conducted not specified. The point of interconnection is on the National Grid 115KV Line R144 between Millbury No. 2 and Woonsocket substations, approximately 5.8 circuit miles from Woonsocket substation. The project has appeared in recent news.
