Lightshift Energy unveiled six new battery energy storage projects across Massachusetts on Monday, adding more than 23 megawatts of capacity to its growing state-wide portfolio and generating an estimated $90 million in lifetime savings for participating municipal utilities and ratepayers.
The projects are planned across the Ipswich Electric Department, Groton Electric Light Department, Princeton Municipal Light Department, Ashburnham Municipal Light Plant, and the Marblehead Municipal Light Department, with capacities ranging from 3 MW to 5 MW.
The Virginia-based energy storage developer said the new installations build on six battery projects already in operation across the state as part of a broader municipal utility program.
According to the company, the battery systems will charge during periods of lower electricity demand and discharge during peak consumption periods, helping municipal utilities reduce transmission and capacity costs that contribute significantly to retail electricity rates in Massachusetts.
The projects are also expected to reduce reliance on fossil fuel-fired generation during periods of high demand, when it is most needed.
Lightshift said its portfolio-based development strategy allows multiple projects to be deployed simultaneously, enabling participating utilities to benefit from economies of scale typically associated with larger standalone projects while accelerating deployment timelines.
"By developing these projects as a fleet across the state, we're able to dramatically reduce cost and increase speed to interconnect, maximizing savings, reliability, and market value for participating communities," Lightshift Co-Founder and Managing Partner Rory Jones said in a statement.
