Lightshift Energy Adds Six New Battery Storage Projects in Massachusetts

Battery storage developer Lightshift Energy has announced the launch of six new battery energy storage system projects in Massachusetts, serving the municipal electric departments of Georgetown, Ipswich, Groton, Princeton, Ashburnham, and Marblehead. These six projects add over 23 megawatts of storage capacity combined, representing the latest phase of the company’s statewide energy plan.

The specific capacities of each project are: Georgetown 3 MW, Ipswich 5 MW, Groton 4 MW, Princeton 3.5 MW, Ashburnham 3 MW, and Marblehead 5 MW. Lightshift stated that these projects are expected to save participating utilities and their customers over $90 million in lifecycle costs.

The storage systems utilize a peak-valley arbitrage model—charging during low-price periods and discharging during peak hours, directly reducing electricity costs for municipal utilities and the communities they serve by cutting peak demand. Lightshift’s portfolio strategy advances multiple projects collectively, leveraging economies of scale to lower costs and accelerate grid interconnection, enabling municipal utilities to achieve economic benefits typically reserved for larger projects.

Rory Jones, co-founder and managing partner of Lightshift, said: “Municipal utilities in Massachusetts have long been pioneers in grid modernization, and these projects continue that tradition. By developing these projects as a portfolio across the state, we can significantly reduce costs, speed up interconnection, and maximize savings, reliability, and market value for participating communities.”

A key partner in this collaboration is the Massachusetts Municipal Wholesale Electric Company (MMWEC), the largest power generation supplier for municipal electric departments in New England. In addition to the six new projects, a seventh project is already under construction, and an eighth is in the late stages of development.
