Project Overview: Sterling Municipal Energy Storage Project

This two-page handout provides a brief overview of the Sterling Municipal Light Department (SMLD) Community Clean Energy Resiliency Initiative. This 2-megawatt/3.9 megawatt-hour battery storage system can isolate from the main grid in the event of a power outage and provide emergency backup power to the Sterling police station and dispatch center, a critical facility providing first responder services. SMLD, which owns and operates the battery storage system, has connected the batteries to an existing 2.4 MW solar array to provide its ratepayers with energy cost savings and community resilient power. This project is the first utility-scale energy storage facility in the state of Massachusetts, and is one of the largest battery installations of its kind in New England.
