The Battery Storage project is a proposed 141.6 MW battery storage development in Litchfield County, Connecticut. The project, located within the ISO-NE region, consists entirely of battery storage. It is listed in the ISO-NE interconnection queue as entry number 1319, with a queue entry date of October 7, 2022, and a proposed commercial operation date of February 23, 2028. The interconnection agreement is currently listed as "In Progress (unknown study)".
The proposed project's point of interconnection is the 115 kV line between the Rocky River and Bulls Bridge substations. The Battery Storage project has been the subject of recent news coverage, with seven articles appearing in industry, development, grid, and regulatory publications.
