Groton 2 harnesses microgrid technology to supply emergency backup power to Florence Roche Elementary School, ensuring educational continuity during grid outages. This dedicated resilience solution goes beyond traditional energy storage applications, demonstrating how battery systems can serve critical community infrastructure.
Project Benefits
In addition to peak shaving and backup power, this second project further supports GELD’s renewable energy portfolio, reinforcing its commitment to sustainable energy generation. Together with Groton 1, these systems deliver $10 million in combined savings while advancing grid modernization.
Beyond the Grid
For the Groton 1 and 2 projects, Lightshift donated $10,000 to the local food pantry, Loaves and Fishes, which provides nutritious groceries and resources to hundreds of families annually.
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.
