Entered ISO-NE interconnection queue
A proposed 135.6 MW battery storage project, named Battery Storage, is under development in Middlesex County, Massachusetts. The project is located within the ISO-NE region and consists entirely of battery storage. It is listed in the ISO-NE interconnection queue as entry number 1553, with a queue entry date of June 4, 2024, and a proposed commercial operation date of May 1, 2028. The project's interconnection status is currently in the System Impact Study phase.
The primary point of interconnection for the project is the National Grid Tewksbury 115kV substation, specifically at an open position opposite the J-162 line. The project has appeared in recent news.
