CT Battery Energy Storage System Projects

Windsor Locks & East Hampton, CT

VHB is partnered with Key Capture Energy, LLC (KCE) a Battery Energy Storage System (BESS) company to deliver the first two fully permitted BESS projects in Connecticut—a 5.02-megawatt BESS in Windsor Locks and a 5-megawatt BESS in East Hampton. Both project petitions have been approved by the Connecticut Siting Council (CSC) and will soon move toward construction. These projects are only two of several other renewable energy projects that VHB is working on to help Connecticut meet its goal of deploying 1,000 MW of energy storage by 2030.

BESS facilities benefit utilities and the communities they serve by making the electric grid more resilient and dependable. The BESS in Windsor Locks site was selected to minimize environmental impacts, fitting entirely onto a former gravel parking lot, and is designed to deliver electricity to power approximately 1,000 homes for four hours in the event of a power outage. The VHB team delivered engineering site plan design, environmental support, and a stormwater management report as well as support with state permitting and petition filings.
