Solidifying Massachusetts as a leader in the nation's clean energy deployment, representatives from across the state, including State Undersecretary of Energy Michael Judge, participated in the project ribbon cutting ceremony. The speakers celebrated how this 3 megawatt battery storage project is a testament to the state’s innovative approach to clean energy with the pairing of a peak shaving project and microgrid that brings multiple benefits to the local community.

GELD Manager Jonathan Patterson said GELD is pleased to bring these projects to the community.

“We are proud to offer the school and our ratepayers in Groton an innovative solution to help maintain low rates while enhancing reliability, reducing Groton’s peak demand, and lowering carbon emissions,” said Patterson.

GELD is one of the first municipal utilities to implement a multi-use microgrid to serve as direct backup power for critical infrastructure while also providing savings to the community. The Groton II microgrid became operational in August 2024 and is the second energy storage project in an ongoing partnership between Lightshift and GELD. Groton I, also 3 megawatts, became operational in July 2024.

“Groton II delivers both cost savings and critical backup power, maximizing the value of energy storage for the community,” said Lightshift Co-Founder and Managing Partner Rory Jones. “This project reflects the leadership and innovative thinking of GELD, and we’re proud to partner on their efforts to strengthen local energy resilience, support clean energy and create value for the community.”

"The Groton II microgrid provides an innovative solution to providing energy at the Florence Roche Elementary School and to residents of Groton,” said State Representative Danillo Sena. “The project is a unique and exciting opportunity to lower energy prices while providing backup power to vital infrastructure. I’m so excited to see the success of this new microgrid!"
