Greenville is being eyed for Maine’s latest battery storage project

MAINE MONITOR • February 25, 2026

Officials in Greenville are considering a proposal to build a battery energy storage facility at a former steam plant. The project, which was pitched to the town select board last week by the New York-based startup Ground Floor Energy, aims to stabilize the local energy grid. Selectmen allowed Ground Floor to go ahead with a pre-application for a grant from the Northern Border Regional Commission, a government agency that funds rural economic development projects. The local green light is a first step for a major energy project. It is an example of Maine working toward its goal of expanding battery storage capacity despite President Donald Trump’s hard turn against many forms of alternative energy.
