Electricity rates in Maine

Households in Maine pay an average of 29.59¢ per kilowatt-hour, above the national average of 18.34¢. That is up 5.2% from 28.14¢ in the same month a year earlier.

What that price means in practice

A price per kilowatt-hour is hard to feel. Here is the same number expressed as money. The most expensive item in the table below is electric furnace, which at 29.59¢ costs about $4,860 a year in Maine against $3,012 at the national average — an extra $1,848 a year for the identical appliance used in the identical way.

Widen that to the five heaviest users in a typical home and the gap compounds: about $12,081 a year in Maine versus $7,488 nationally. None of that is a difference in how much electricity you use. It is the same consumption at a different price.

Prices here rose 5.2% over the year to June 2026, against +5.0% nationally. On the five-appliance basket above that shift is worth roughly $592 a year by itself.

Business electricity rates in Maine

Businesses do not pay the residential rate. EIA publishes commercial and industrial averages separately, and the gap between them is one of the larger and less discussed differences in US electricity pricing.

Residential

29.59¢

homes

Commercial

22.24¢

shops, offices, restaurants

Industrial

14.21¢

manufacturing, large plant

A small business in Maine paying the commercial average of 22.24¢ pays about 25% less per kilowatt-hour than a household here. On a commercial refrigeration or HVAC load running most of the day, that difference compounds into real money — a single 3 kW load running 12 hours a day comes to roughly $2,922 a year at the commercial rate.

Commercial and industrial customers are usually billed on demand charges and time-of-use tariffs as well as per kilowatt-hour, so a real bill will not match a flat average. Treat these as a baseline for comparing states, not as a quote.
