Property tax relief for battery storage

Beginning April 1, 2026, battery storage at your home or business qualifies for Maine property tax relief. The equipment can be exempt as business equipment, or you can seek state reimbursement for taxes on it. To qualify, more than 50% of the battery’s output must serve load behind your meter at the site, or the owner must have a signed interconnection agreement with a utility by January 1, 2025. A battery storage system is common energy storage tech, like lithium‑ion.
