Ground Floor Energy Proposes Battery Storage Facility in Greenville, Maine

ENERGY STORAGE

Ground Floor Energy has proposed a battery energy storage facility in Greenville, Maine, at a former steam plant site. The project aims to stabilize the local energy grid. The Greenville select board has permitted Ground Floor to apply for a grant from the Northern Border Regional Commission.

This project aligns with Maine's goal to expand battery storage capacity, with a target of 400 megawatts by 2030, as current facilities provide over 230 megawatts. The site is associated with Clean Maine Carbon, which operates a biochar production facility. If the grant is approved, further discussions will be needed with the select board.
