Reliable Service and Stable Prices

The Maine Public Utilities Commission (MPUC) has approved an annual adjustment of CMP electric delivery prices effective July 1, 2020. Most of the price adjustment is related to extraordinary costs associated with major storms including the October 2019 Nor’easter, when 230,000 customers lost power, and a subsequent November 2019 storm which caused 180,000 outages. Rather than collecting these costs all at once, CMP proposed, and the MPUC agreed, to extend the period for collecting the costs associated with storm recovery over three years instead of one year to alleviate immediate impacts on customers during the current economic crisis. The price change also includes costs related to an increase in funding for energy efficiency programs, changes in federally mandated transmission costs and several accounting and tax adjustments.

The average residential customer will see a price increase of 2.8% on their total bill. The average small business customer will see a price increase of 0.6% on their total monthly bill. Specific pricing information can be found below.
