ENGIE North America Inc. and Holyoke Gas & Electric Department said Oct. 4 that they plan to install a 3-MW energy storage system at the 5.8-MW Mt. Tom solar facility in Hampden County, Mass.
The storage system will help stabilize rates for Holyoke customers and reduce stress on the distribution system for the next 20 years, ENGIE and Holyoke said in a news release, describing it as the largest utility-scale energy storage installation in Massachusetts.
"Solar and energy storage are keys to a low-carbon, low-cost energy future and [Holyoke] is taking the lead by moving forward proactively to deploy what we see as the future for the energy industry," ENGIE North America President and CEO Frank Demaille said in a statement.
"We are pleased to work with ENGIE on the Mt. Tom energy storage project, which will produce peak demand and asset management benefits that will help [Holyoke] stabilize electric rates over the long term," Holyoke manager Jim Lavelle said. "This project also adds a measure of resiliency to our local grid, helping us to better serve our customers."
Holyoke was awarded a $475,000 Massachusetts Department of Energy Resources grant to contract with, schedule and analyze the storage system.
ENGIE North America subsidiary Green Charge Networks, upon completing the storage system in April 2018, will also operate it.
