The facility has a storage capacity of 16.2 megawatts of power, the largest in New England and a significant percentage of the 30-100 MW needed to meet New England’s power needs on a given day.

Battery storage is hailed as a “non-transmission alternative” way to even out the highs and lows of both energy demand and the intermittent power supply from renewable sources like solar and wind power. Ellen Foley of ISO-New England is quoted as saying, “The role of grid-scale electricity storage will grow as the region moves closer to its clean-energy goals, while maintaining a reliable power system.”
