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.

How Are Prices Determined?

Who is responsible?

The prices, practices, and level of profitability are regulated primarily by the Maine Public Utilities Commission (PUC). The PUC was created by Maine law and began work in 1914. Its three commissioners were nominated by the Governor and confirmed by the Maine Senate.

The Commissioners are assisted by legal, technical, financial and consumer-assistance staff. PUC proceedings use court-like standards of evidence, procedure and decisions that allow opportunities for interested citizens or groups to participate as formal interveners in the process.

Office location: 101 Second St. Hallowell, ME 04347

Mailing address: 18 State House Station Augusta ME 04333-0018

Telephone: 207.287.3831

Website: www.maine.gov/mpuc

Our transmission prices are determined by the Federal Energy Regulatory Commission (FERC).

How does the PUC set delivery prices?

There are five components that make up a delivery price. The PUC separately sets the five pieces that make up our delivery prices.

The distribution piece covers the costs of local power lines, meter readers, and bucket trucks. For most customers, this makes up the majority of their delivery price.
The transmission piece covers the costs of large power lines and substations and is regulated by the Federal Energy Regulatory Commission.
The stranded cost piece covers costs of power contracts with small hydro, biomass, waste-burning and nuclear plants that were left over from before we became a delivery-only utility (we ceased selling energy when that part of the electric business was de-regulated in March 2000). Stranded costs continue to decline.
The conservation assessment piece funds energy efficiency initiatives.
The Electricity Lifeline Program (ELP) provides assistance to residential customers who qualify for the Home Energy Assistance Program.
