Maine Residential Electric Rates

cmp electricity 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.

Below is all you need to know about the different energy products that energy companies offer to Maine residents:

  • More flexible than fixed-rate, can exit without incurring fees
  • More expensive than fixed rates
  • Supplier is free to hike up the price

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.

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.
