Maine Energy Storage Policy and Market Overview

The energy storage market in Maine is competitive and a national frontrunner. Robust policy actions, comprehensive interconnection guidelines, R&D funding, and BTM incentives are leading the state’s energy storage market.

In 2021, Maine legislated an energy storage procurement goal set at 400 MW by 2030 (LD 528). As of March 2024, the state has 6 FTM, grid-scale energy storage projects with a total capacity of 63 MW. To ensure sustained deployment of storage systems, state regulators have dedicated resources to efficient and effective roll-out. The state appointed eight new state positions dedicated to energy storage program success (LD 1614) and piloted a demonstration program that provides backup storage to critical municipal facilities (LD 528).

Maine is committed to a comprehensive energy storage procurement strategy. State regulators are devoting resources that will prolong growth and stabilize the grid. Updated market assessments, and Long-Duration Energy Storage research and demonstration will ensure capacity growth that will lead national storage procurement.
