Maine Municipal Utility
Solar & Clean Energy Guide

Maine has 5 municipal utilities. These are locally owned electric utilities that set their own rates and incentive programs independently of investor-owned utilities.

Many municipal utilities in Maine offer solar rebates, though the amounts vary. Some offer per-watt rebates (typically $0.25–$1.00/watt), while others offer flat rebates or no solar-specific incentives. Check the individual utility listings on this page for current rebate details.

Net metering availability varies by municipal utility. Most offer some form of net metering or solar credit program, but the specific terms (full retail rate vs. avoided cost) differ. Each utility listing shows their current net metering status.

Municipal utilities in Maine typically offer rates that are 10-20% lower than investor-owned utilities. This is because municipal utilities operate as non-profits and don't pay shareholder dividends. Lower rates mean different solar payback calculations — use our calculator on each utility's page for accurate estimates.
