High electricity prices hinder some industries

Unfavorable movement since the last available data

Benchmark: The cost of electricity in Maine will decline to the U.S. average by 2030.

Overview Fig. A


Electricity is a significant cost for many businesses, especially those in energy-intensive industries such as manufacturing. The energy intensity of Maine’s economy is about average for the U.S. (ranking 22nd of the 50 states in 2019) but the highest in New England.

The average industrial retail price of electricity in Maine rose 10% in 2021, from 8.86 to 9.76 cents per kilowatt hour. This was double the national growth rate but similar to the rest of New England. Maine’s industrial electricity rates are still the lowest in New England, and 28% below the regional average, but they exceed the national average by 34%.

New renewable energy sources could help reduce costs and lower emissions, but they require increased investment in Maine’s strained transmission system. A coordinated transmission anticipation process could help address this issue.
