According to the U.S. Energy Information Administration retail-sales series (2025 annual frequency), residential electricity in Maine costs 27.78¢/kWh, 60.6% above the national average. Since 2016, the rate has changed +75.5%.
Where Maine sits: according to EIA's annual retail-sales series, its residential rate changed +75.5% between 2016 and 2025, the 3rd steepest of 51 jurisdictions (the 50 states and the District of Columbia), a steeper move than 96% of the other 50. Ranked on the same 2016 to 2025 window for every state; see the methodology.
Price Trends, Maine vs National Average
Reading the Maine Price Trend
According to the U.S. Energy Information Administration's retail-sales series, RateWatt currently holds 2,040 annual state-sector records spanning 2016 through 2025. These are statewide annual averages, not individual utility quotes. See the methodology for source scope and refresh cadence.
Maine residential electricity moved from 15.83¢/kWh in 2016 to 27.78¢/kWh in 2025, a cumulative change of +75.5% over 10 reporting years. The more recent five-year window changed +65.3% since 2020; comparing the two windows describes whether the pace changed, but does not establish why. Against the national residential benchmark of 17.30¢/kWh, Maine now sits 60.6% above the U.S. average for 2025.
Commercial customers in Maine paid 20.96¢/kWh in 2025, while industrial customers paid 15.50¢/kWh. Sector differences can reflect customer mix, consumption volume, tariff design, and cost allocation; this statewide series does not identify which factor drives a state's gap. Here the residential-to-industrial multiplier is about 1.8x, one descriptive benchmark for comparison with peer states.
EIA reports 8 generation sources for Maine; ranked by share of generation they run natural gas, solar, wind, hydro, other. Of the 11 sources EIA reports somewhere in the country, Maine records no generation from geothermal, nuclear or pumped storage. That is an absence in the published series, not a statement that no such capacity exists. This price series and that generation series are published separately and are not joined here, so nothing on this page attributes a price movement to a fuel mix. Adjacent entries in the alphabetical state browser are Louisiana and Maryland; their pages carry the same series on the same basis. EIA publishes the annual series once per year and revises prior years without renumbering them, so a figure here can change when a later release restates it.
The annual average is close to what most months look like
Maine is one of 20 states, of the 51 with a full monthly record, whose residential rate moves within a narrow band across the year. The monthly series runs from about 25.79¢/kWh in February to about 28.20¢/kWh in December, a spread of 9.1% around the monthly mean. Where that spread is this small, the annual figures in the table above describe an ordinary month here reasonably well, which is not true of every state.
Within-year profile computed from 36 monthly observations across 3 complete calendar years in EIA's residential series (monthly data begins 2023-01). Partial calendar years are excluded so a newer partial tail cannot bias January–May against later months. Peak and trough are the highest and lowest month averages across that record, not a forecast; the spread is quoted against this state's own monthly mean.
How often the rate has actually fallen
Maine's rate has fallen in 2 of the 9 year-on-year steps on record, the most common pattern among states. The steepest of those falls came in 2024, at 3.13¢.
The recent climb is steeper here than in most of the country
Across the full 9-year record Maine residential prices rose about 6.4% a year. Over the last five they rose about 10.6% a year. That 4.1% step-up is bigger than the one recorded in 94% of states, so the recent path diverged more sharply from this state's own long-run pace than most.
Both figures are compound annual rates over EIA's published residential series, so the five-year and full-record windows are directly comparable; the national comparison ranks all 51 states and DC on the same measure. Annual state-level averages, not individual bills.
