Retail Competition Background:

The law that required the restructuring of the electric utility industry in Maine was passed in March 2000. This change provided Maine consumers with the ability to choose their electricity supplier – the company that supplies their electric energy. Until 2000, a single utility company, regulated by the Commission, supplied and delivered electricity. With electric restructuring, Maine began to develop a competitive market for electricity supply. This market developed quickly for larger commercial and industrial consumers, who have a number of choices for their electricity supplier. Many small consumers, like residential and small businesses, are also now able to choose their electricity supplier.

Customers without a choice, or those who do not wish to choose, are automatically provided with Standard Offer Service.

Delivery service is still provided by the local utility (now called a distribution company), such as Bangor Hydro Electric, Central Maine Power, Maine Public Service, or one of Maine’s consumer owned utilities

All customers may choose their electricity supplier either by selecting a CEP or remaining on the Standard Offer default service. For a list of suppliers, go to the MPUC’s on-line supplier list at Customers can compare an offer from a CEP with the Standard Offer rate by reviewing their bills (if they are on the Standard Offer), or by visiting the MPUC’s website to see the current standard offer. Once a residential or small commercial customer has enrolled with a CEP, the CEP is required to provide a “Terms of Service” document to the customer within 30 days. This document is required to contain information relating to price, contract terms, resource mix, and emissions. CEPs are also required to provide customers with the right to rescind the contractual agreement within 5 days of the customer’s receipt of the terms of service document.

Maine’s electric prices track those of the New England region and, particularly for businesses, tend to track lower than those of the rest of New England (see figures below):

New England as a region has higher electricity costs than other regions in the nation because it does not have its own indigenous power supply like the coal of the south or the oil of Texas or big hydro of the northwest.

Maine’s electricity supply costs are determined by the New England wholesale market prices, which generally track the cost of natural gas fueled generation. Natural gas costs have declined in recent years due to over-supply from depressed demand as a result of the national and global recession and recent discoveries of natural gas supply in shale. Wholesale electricity prices in New England have declined similarly, and have resulted in reductions – in turn – to retail supply prices in Maine as new supply (such as for standard offer service) is acquired at these reduced price levels.

The price of electricity for Maine customers includes several separate elements. Supply (includes energy generation, capacity, and ancillary costs) is determined by competitive markets and not regulated by the Commission. Distribution is provided by the utilities and regulated by the Commission. Transmission costs are regulated by Federal Energy Regulatory Commission (FERC – a federal regulatory body). Stranded costs are a small and declining component of delivery (for example, less than ½ cent per kilowatt hour for Central Maine Power).

The residential price of electricity at this time: For supply, approximately 9 cents per kilowatt hour (kWh), based on standard offer price (a retail price) in Central Maine Power’s territory; plus transmission and distribution combined cost of approximately 6 cents per kWh, for a total on customers’ bills of just under 16 cents per kWh (based on 2009 residential rates).

The table below provides a comparison of retail prices for various classes of customers in Maine and other states in the northeast as of Fall 2010.
