New England’s largest standalone battery facility is now operating in Maine, bringing the state a key step closer to the Mills administration’s electrification and clean energy goals. The Cross Town Energy Storage facility boasts a capacity of 175 megawatts, bringing the state’s total energy storage capacity to about 240 megawatts — more than halfway to its capacity goal for the end of 2030. At a Wednesday ribbon-cutting, Gov. Janet Mills touted the roughly 5-acre facility as a key part of the state’s transition to 100% clean energy by 2040, a goal the Maine Legislature formalized last year.
