Entered ISO-NE interconnection queue
The proposed Battery Storage project is a 514.8 MW battery storage development in Middlesex County, Massachusetts. The project, under queue ID ISO-NE-1567, is located within the ISO-NE region and was entered into the interconnection queue on June 11, 2024. The developer has proposed a commercial operation date of January 31, 2027.
The project's interconnection status is currently in the System Impact Study phase. The Primary Point of Interconnection will be a direct interconnection located on the property at coordinates 42°41'23.38"N, 71°26'20.43"W, tapping the 345-kV Line 326-2 (Sandy Pond-Lawrence Rd), owned by RI_NGRID, approximately 8.4 miles from the 345-kV Lawrence Rd Substation. The project has appeared in recent news.
