Maine Residential Electric Rates

The State of Maine began consideration of electric deregulation in 1995, but it wasn’t until 2001 that the energy marketplace really opened. What that meant in practice for Mainers was that they were free to switch their electricity supply from a state utility company to a competitive retailer. The main driver is, of course, the price – the average residential electric rate in Maine is 16.79 cents per kilowatt-hour, as opposed to the national U.S. average of 12.79 cents per kilowatt-hour.
Currently, residential and commercial customers of two power utilities are able to shop for electricity rates – CMP and Emera Maine – covering approximately 60% of the territory. If you decide to switch, these utility companies will still be responsible for safely delivering electricity to your home. However, when it comes to the electric rate – you have the freedom to choose.
Compare Electricity Rates in Maine
The Maine Public Utility Commission tries to empower the residents to use the electric choice. It publishes a list of licensed electric suppliers in the state, but currently, there is no official state resource for the Mainers to compare the available rates and make the switch.
That’s why we are here. On our website, you can compare rates in Maine by simply entering your zip code. We carefully review all retail suppliers to also include information about customer service contact details, bill payment options, and little extras that they offer to customers.

Alternative Energy Options in Maine
Maine has tremendous potential when it comes to green power. In 2018, about three-fourths of the state electricity net generation came from renewable sources. With such a high share of green power – Mainers have not one but a few options to green up their energy usage:
![]() | Maine Green Power - The Public Utility Commission plays a key role in promoting the adoption of renewable energy - its official Maine Green Power program allows you to sign up a portion of your bill to purchasing Renewable Energy Certificates (RECs). These certificates are proof that energy was generated from renewable resources, such as wind, hydro and biomass and can be used to offset your carbon footprint. |
![]() | Choose a green energy plan - In 2019, the state governor signed in a bill, mandating that 80% of the energy generated in Maine will come from renewable sources by 2030. Power suppliers had to comply and as a result, Mainers are now able to switch to partially or fully green energy plans with competitive prices. |
![]() | Community solar projects - Anyone who pays an energy bill in Maine (businesses or homeowners) can be a part of a community solar project. These projects leverage economies of scale and state incentives to give more people access to cleaner, cheaper energy without the upfront investment costs. |
