Tunnel Battery System
The Tunnel Battery Energy Storage System (BESS) project, being developed in collaboration with New Leaf Energy, will replace the Tunnel Jet Gas Peaker, which is scheduled to be decommissioned in 2023. The 17 MW BESS project will provide equivalent energy to the existing fossil-powered Jet but will bring new benefits to the grid by charging when surplus energy exists on the grid that would otherwise go unused while reducing GHG emissions. The Tunnel BESS project will be co-located with FirstLight’s existing Tunnel Hydro facility, highlighting the opportunity to pair batteries with hydropower to increase renewable energy supplied to Connecticut communities.
