Maine electricity prices in context

Maine's residential electricity rate stood at 32.11¢/kWh in August 2026, the second-highest among the 50 states and DC. This rate exceeded the national average of 18.16¢/kWh by 13.95¢/kWh, or 76.8% above the US figure. New Hampshire, the only bordering state in the data, charged 27.64¢/kWh, making Maine's rate notably higher still.

Over five years, the rate has climbed 87.4%, from 17.13¢/kWh in August 2021. The increase stretches back much further: since August 2006 it has risen 134.9%, and since records began in January 2001 it has increased 147.8% from 12.96¢/kWh. The current rate sits just below the state's record high of 32.41¢/kWh set in July 2026. It remains far above the all-time low of 10.66¢/kWh recorded in January 2002. Commercial and industrial rates in August 2026 were 21.33¢/kWh and 14.24¢/kWh respectively.

The state's average residential bill reached $156 per month on 527 kWh of usage. The national average bill was $158 on 876 kWh per month. Maine households used substantially less electricity than the national average while paying a bill that remained comparable to the country overall, a reflection of the state's elevated price per unit alongside lower consumption patterns.
