Electricity Supply Prices Set for Standard Offer Service in Central Maine Power Territory

November 17, 2015

Hallowell, Maine — In a competitive solicitation concluded today, the Maine Public Utilities Commission (“Commission”) accepted bids and set new prices for standard offer electricity supply for customers of Central Maine Power (CMP) who receive standard offer supply service. The new prices are effective for a twelve-month term beginning January 1, 2016.

For CMP residential and small business customers who receive standard offer supply service, the accepted bids result in a new standard offer price of 6.46 cents/kWh on an annual average basis, which is a 3.7% decrease compared to the annual average price during 2015. For CMP medium business customers, the new prices differ by month, equating to about 6.92 cents/kWh on an annual average basis, varying from 5.52 cents/kWh in May 2016 to 9.62 cents/kWh in February 2016. These medium class prices are about 11% lower than prices during the same twelve month period last year. The bids accepted for large business customers are indexed to the market, and prices will be set by the Commission in advance of each month based on then-current market prices.

These new prices apply only to standard offer service, which reflects about 40%-45% of the sales in CMP’s service area. The prices do not apply to customers that purchase their own electricity supply in the market.

“The standard offer prices set this week reflect the best bids received in a strongly competitive auction process,” according to Commission Chairman Mark Vannoy. “We are pleased that prices remain stable or slightly decreasing allowing retail customers and businesses to benefit from recent downward trends in energy markets that have been reflected in New England wholesale prices.” said Vannoy. Vannoy noted that it is difficult to say whether these recent trends will continue, given continued strong demand for natural gas in the region and the seasonal constraints on pipeline capacity to transport natural gas to New England.

The names of the suppliers selected will be released in two weeks, allowing time for power supply arrangements to be finalized. Solicitations for standard offer electricity supply service for Emera Maine beginning January 1, 2016 are expected to be concluded by the Commission on Wednesday, November 18, 2015.

Background: Electricity customers in Maine receive standard offer service if they have not purchased supply from another retail supplier or through an aggregator. Currently, standard offer service represents about 40%-45% of the supply used by CMP customers. Maine law requires the Commission to ensure that standard offer service for electricity supply is available to all customers in Maine. The Commission arranges for standard offer service through periodic competitive bid processes.
