About this incentive
Maine grants a business equipment property tax exemption to battery storage systems, as long as more than 50% of the output from the system serves an on-site, behind the meter load, or there was an executed interconnection agreement between the system owner and a utility by January 1, 2025. The tax exemption addition applies to property tax years beginning on or after April 1, 2026.
