LD 819 Maine House · 132nd Legislature (2025-2026)

An Act Concerning The Status Of Battery Storage Systems With Regard To The Business Equipment Tax Exemption

This bill changes Maine's business equipment tax exemption rules for large battery storage systems. It specifically removes the tax exemption for systems with a total capacity of 2 megawatts or more. The law directly affects businesses installing or operating commercial-scale battery storage systems (like those used for grid support or large facilities), requiring them to pay taxes on these systems. The key provision clarifies that only smaller battery systems qualify for the existing tax exemption, while larger installations do not.
