Maine Electricity Price Trends

Reading the Maine Price Trend

Maine residential electricity moved from 15.83¢/kWh in 2016 to 24.29¢/kWh in 2024, a cumulative change of +53.4% over 9 reporting years. The more recent five-year window tells a slightly different story: +35.8% since 2019, which captures the post-2020 commodity and capacity-cost pressures that reshaped most U.S. utility rate bases. Against the national residential benchmark of 16.48¢/kWh, Maine now sits 47.4% above the U.S. average for 2024.

Commercial customers in Maine paid 18.22¢/kWh in 2024, while industrial buyers, typically interruptible, high-load-factor accounts, paid 12.46¢/kWh. That sector spread is informative on its own: a large residential-to-industrial gap usually signals heavy cross-subsidy in the tariff book, while a narrow gap indicates rates closer to marginal cost. Here the residential-to-industrial multiplier works out to about 1.9x, giving planners and ratepayer advocates one quick way to benchmark against peer states.

For consumers and small businesses in Maine, the most practical takeaway from this dataset is direction, not just level. A 53.4% climb since 2016 means bill-impact planning should assume continued upward pressure unless a structural change, new capacity, fuel-mix shift, or regulatory reset, enters the picture. Pairing this state view with neighbors (Louisiana, Maryland) helps separate regional fuel-market effects from state-specific policy drivers. EIA publishes these series annually, so each successive year of data progressively sharpens the picture.
