Overview
- Lightshift announced Monday that it will add more than 23 megawatts of battery capacity across Georgetown, Ipswich, Groton, Princeton, Ashburnham and Marblehead.
- Ipswich’s 5‑MW site is in final-stage construction, while the five other towns still need major municipal permits and are expected to be energized within about three years.
- Lightshift negotiated contracts with each municipal utility and with the Massachusetts Municipal Wholesale Electric Company to place the systems on municipally owned sites under long-term agreements.
- The batteries will charge during low-demand hours and discharge at peak times to shave transmission and capacity charges, a practice that directly lowers bills and reduces reliance on fossil-fuel generation.
- The rollout builds on Lightshift’s fleet approach, which already includes six operating projects, a seventh under construction, and more in development, and is intended to speed interconnection and capture economies of scale for small municipal utilities.
