Have Maine power prices risen 55% since 2015? | Fact brief

Maine power prices have gone up by more than 55%, for both retail and residential customers, since 2015.

According to the U.S. Energy Information Administration, the average retail price of electricity in Maine went from 12.78 cents per kilowatt-hour in 2015 to 22.81 cents in 2025 — an increase of about 78.5%.

Figures from a February 2026 Maine Department of Energy Resources webinar also indicate average Maine residential electricity rates increased by 60% — from 15 cents per kWh in 2015 to 24 cents in 2025 — during the same period.

The primary drivers cited were natural gas prices, storm recovery costs, aging infrastructure and inflation. The department said diversifying Maine’s energy sources and investing in energy efficiency can help reduce price volatility.

Maine’s electricity supply prices nearly tripled from 2021 to 2023, the Department of Energy Resources said, driven by global natural gas shortages caused by Russia’s invasion of Ukraine.
