Questions & answers about Standard Offer service

What is the "Standard Offer?"

The Maine law that created electric competition on March 1, 2000, provides that any customer who does not designate a Competitive Electricity Provider for their electric-energy supply will receive Standard Offer service arranged by the state.

Under terms of the law, CMP no longer sells electricity; we deliver electricity, maintaining and operating the more than 150 substations and 20,000-plus circuit-miles of power lines required to perform that service.

Electric bills now reflect separate charges for CMP delivery service, and for each customer's electricity supplier, whether a competitive provider or the Standard Offer. Putting supply and delivery charges on the same bill was judged more convenient for consumers than sending two bills for each month's service. CMP forwards the supply portion of customers' payments to the appropriate supplier.

How are Standard Offer prices set?

The Maine Public Utilities Commission (MPUC) accepts bids from competitive electricity suppliers to supply Standard Offer service for CMP customers who have not designated a competitive electricity supplier.

What are the Standard Offer prices for residential and small business customers?

The Standard Offer price for residential and small business accounts is 7.92 cents effective January 1, 2018. This price will stay the same through December 31, 2018. From January 1, 2017 through December 31, 2017, the Standard Offer price for residential and small business accounts was 6.69 cents.

What are the Standard Offer prices for medium business and large business customer?

Standard Offer prices for medium and large customers vary by month. Details on these prices can be found on the MPUC website

How can a business customer tell whether they are small, medium, or large?

These classifications are based on the level of peak demand for electricity. This rate classification can be found on the first page of your bill. Small customers (SGS) have demand of less than 20 kilowatts (kW) and they do not pay a demand charge. Medium customers (MGS) have demands between 20 kW and 400, while large (IGS & LGS) have demands greater than 400 kW. Both medium and large customers pay demand charges, too.

Where can customers find more information?

The Maine PUC registers and maintains a list of energy providers. Customers can contact the PUC by phone at 207-287-3831, or online at
