How are CMP prices set?  

Who decides
Central Maine Power's prices?

The prices, practices, and level of profitability of CMP and other Maine public-utility companies 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 must be 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, and include opportunities for interested citizens or groups to participate as formal intervenors or to receive information updates.

PUC offices are at 101 Second Street in Hallowell. The mailing address is 18 State House Station, Augusta, ME 04333-0018. Telephone (207) 287-3831. The PUC's Internet address is www.maine.gov/mpuc.


CMP's transmission prices are determined by the Federal Energy Regulatory Commission (FERC).

How does the PUC set CMP’s delivery prices?

The PUC separately sets the five pieces that make up CMP’s delivery prices. The distribution piece covers the costs of local power lines, meter readers, bucket trucks and so forth. For most customers, this is the biggest piece of CMP’s 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 are left over from before CMP became a delivery-only utility (CMP 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.
