Massachusetts Public Power Utility Holyoke Gas & Electric Lines Up Third Battery Storage Project

Convergent Energy and Power will provide Massachusetts public power utility Holyoke Gas & Electric with a 5 megawatt/15 megawatt-hour utility-scale battery storage system, which is expected to stabilize costs for its customers and further insulate against rising energy prices.

Convergent will own and operate the battery and the battery storage system is projected to come online in 2023.

Convergent noted that the energy storage system will be the third battery storage project for Holyoke Gas & Electric.

Citizens Energy in 2021 brought online a battery storage system for Holyoke Gas & Electric. This battery system was the second that will contribute to lowering peak costs for Holyoke Gas & Electric customers.

The public power utility previously installed a 3 MW, 6-MWh battery system connected to the 5.8-MW Mount Tom solar facility in western Massachusetts. The solar array was built in 2016 on property that was once part of the coal-fired Mount Tom Power Station. 

The American Public Power Association’s Public Power Energy Tracker is a resource for association members that summarizes public power energy storage projects that are currently online. The tracker is available here.
