Battery Storage in Kennebunk, ME

Kennebunk, Maine homeowners are adding battery storage to protect against power outages, reduce peak electricity costs, and maximize solar savings. The local utility, Kennebunk Light & Power District, charges $0.12/kWh for residential electricity. With Maine averaging 18 hours of outages per year, a home battery provides critical backup power when the grid goes down.

A home battery stores solar energy generated during the day for use at night and during outages. When paired with solar panels, battery storage allows Kennebunk homeowners to dramatically reduce grid dependence and protect against rising utility rates.

The federal residential energy storage tax credit (Section 25D) expired December 31, 2025. Homeowners purchasing batteries with cash or a loan no longer receive any federal tax credit. However, the Efficiency Maine provides up to $4,000 in state-level rebates, making this the primary financial incentive for Kennebunk battery installations. Kennebunk Light & Power District adds a $2,000 utility battery rebate on top of state incentives.
