HOLYOKE, MA (WGGB/WSHM) — There’s some potential energy relief for residents in Holyoke. On Thursday, Citizens Energy turned on a new battery energy storage system in the city.

The nearly five megawatt system will allow Holyoke Gas and Electric to have an alternative source of energy for customers when the demand and cost of power peaks during the day.

Former Congressman Joseph Kennedy founded Citizens Energy more than 40 years ago.
