About

The Battery Storage project is a proposed 214.16 MW battery storage development in Essex County, Massachusetts. The project is located within the ISO-NE region and is listed in the ISO-NE interconnection queue as queue ID 1555, with an entry date of June 6, 2024. The proposed commercial operation date is January 1, 2028.

The project's interconnection status is currently in the System Impact Study phase. The point of interconnection (POI) is the 115KV Line Q-169 between Resco-Saugus Tap and Melrose #2 Tap, approximately 2.4 miles from Melrose #2 Tap and approximately 2.35 miles from Resco-Saugus Tap.
