MMWEC & Lightshift Energy to partner on 50MW of US BESS projects

May 8, 2024

The Massachusetts Municipal Wholesale Electric Company (MMWEC) has chosen energy storage project developer Lightshift Energy as exclusive partner to deploy the state’s first jointly implemented fleet of grid-scale battery energy storage systems (BESS).

Lightshift will build up to 50MW of BESS across MMWEC utility membership, which represents half of all municipal utilities in the state, serving nearly 200,000 customers. Lightshift estimates the partnership will provide over $200 million in cost savings for municipal customers.

As part of the agreement, participating utilities within MMWEC’s membership will host one or more Lightshift energy storage projects. The initial wave of projects will commence operations this summer, with four projects already under construction in the towns of Groton, Holden and Paxton. Late-stage development activities are already underway in the towns of Peabody, Shrewsbury, Wakefield, Chicopee, Ipswich and Princeton, with mid-stage development activities “moving forward in several other communities”, according to a statement. The portfolio is scheduled to come online throughout 2024 and 2025.

“MMWEC is pleased to partner with Lightshift Energy on this battery energy storage system project,” says MMWEC CEO Ronald C. DeCurzio. “The project demonstrates yet again how the municipal utilities are leading the way in decarbonisation in Massachusetts, in alignment with the Commonwealth’s emissions reduction targets.”

Rory Jones, Lightshift co-founder and managing partner, added: “This is a significant milestone for Massachusetts and for the participating utilities which are demonstrating leadership in grid modernisation while prioritising cost reduction for their communities. And MMWEC has been pivotal in facilitating this first-in-kind program that other states will look to as a means to achieve major impact through community-based storage, at scale.”
