Rate transparency information is posted in accordance with An Act To Provide Transparency in Electricity Pricing for Maine Ratepayers and the Commission’s Report on Transparency in Electricity Rates and Assessments. The purpose of the Act is to create increased transparency regarding the costs and effects of State energy policies on electricity rates. To put these costs in perspective and provide greater electric rate transparency, this reporting also itemizes costs associated with transmission, distribution, and supply.

A description of the benefits associated with each State energy policy is available below the charts.

Please note:

  • The rates presented represent average rates over all rate classes. 
  • Not all components apply to all rate classes.
  • Supply costs are inclusive of certain State energy policies, such as the Renewable Portfolio Standard and the Regional Greenhouse Gas Initiative.
  • Regional Greenhouse Gas Initiative costs reflect only the small class loads served by standard offer service.
