SECTIONS 9

Maine electricity shopping starts with a simple split: the delivery utility stays in place, while the supply portion can come from the state-arranged Standard Offer or from a licensed Competitive Electricity Provider. That makes Maine different from a market where the utility itself is the only supply option. It also means the first number a shopper should identify is not a statewide average but the correct Standard Offer for the utility territory serving the home. The U.S. Energy Information Administration reported a Maine residential average of 28.63¢ per kWh for May 2026; that figure is useful context for the overall market, not a quote for an individual account.

Maine has several default-supply benchmarks, not one

The Standard Offer is procured under Maine Public Utilities Commission oversight, but the benchmark differs by delivery territory. For 2026, residential and small-commercial Standard Offer supply was listed at 12.721¢/kWh for Central Maine Power, 12.954¢/kWh for Versant’s Bangor Hydro District, and 14.88¢/kWh for Versant’s Maine Public District. Those values describe supply only. A household comparing a CEP in CMP territory should therefore use the CMP benchmark rather than borrowing a Versant figure or the statewide EIA average.

Start with the utility name on the bill

Before looking at supplier advertisements, confirm whether the account is served by Central Maine Power, one of the Versant districts, or another local utility. The delivery company remains responsible for the distribution system after a supply switch. Metering, poles and wires, and outage response do not transfer to the CEP. The practical shopping question is narrower: can an alternative supplier improve on the supply arrangement the customer already has, once term length, fees, renewable content, and renewal rules are considered?

Why the Standard Offer matters so much in Maine

Maine public guidance has noted that roughly nine in ten residential and small-business customers receive Standard Offer service. That makes default supply more than a technical fallback; it is the real-world starting point for most comparisons. A competitive offer should therefore demonstrate a specific benefit. That benefit may be a lower verified supply cost, a preferred renewable product, or another contract feature the household values. Merely being “competitive” does not make the alternative better.

Evaluate CEP offers as contracts, not rate cards

A small discount can disappear if the offer changes after an introductory period, adds a recurring fee, or rolls into variable pricing. Read the full contract horizon and ask what happens when the initial term expires. Maine’s consumer materials emphasize checking current supplier terms because offers can change. The best comparison uses the same recent kWh consumption for the Standard Offer and the CEP, then adds any recurring contract costs rather than comparing two isolated cents-per-kWh labels.

Renewable supply deserves its own comparison

Some customers are willing to pay more for a product with stronger renewable attributes; others prioritize the lowest expected bill. Those are separate decisions. Compare the price formula first, then review what the renewable claim actually represents. Our renewable electricity guide explains why electricity delivered through the shared grid and the renewable attributes associated with a retail product are not the same thing.

A Maine shopping sequence

Identify the delivery utility and the exact service territory.
Find the current Standard Offer that applies to that territory.
Review several months of actual kWh, preferably a full year.
Calculate the CEP offer using the same consumption.
Check fixed or variable pricing, recurring fees, cancellation rules, and renewal language.
Confirm that the supplier is currently licensed and that the quoted offer is still active.

The Maine Public Utilities Commission consumer guidance is the primary public reference for the supplier-choice framework used here. For broader context, use our electricity rates by state data and deregulated electricity states guide, but keep Maine’s territory-specific Standard Offer structure at the center of any actual decision. Data note: EIA statewide price is May 2026; the competitive-offer table was checked August 1, 2026, and 2026 Standard Offer figures should be rechecked before later implementation.

Compare savings over the contract, not one billing month

Maine supplier offers are easier to judge when the customer converts both options into expected dollars over the same period. Multiply the applicable supply price by the household’s actual kWh for several months, then add any supplier-specific recurring fee or credit. Repeat the calculation for the Standard Offer. If the CEP contract lasts beyond the period covered by the currently published Standard Offer, do not assume the benchmark remains unchanged forever; mark the comparison as conditional and revisit it when a new Standard Offer is announced. This prevents a small temporary difference from being presented as guaranteed annual savings.

Contract end dates deserve a reminder

A customer who switches away from Standard Offer service should record the CEP contract expiration date at enrollment. The important question is what the agreement says happens next: renewal at a new fixed rate, conversion to variable pricing, or another arrangement. A calendar reminder gives the household time to compare the new CEP terms with the then-current Standard Offer before the old agreement ends. In Maine, where Standard Offer service is widely used, returning to the default benchmark can be a legitimate option rather than a failure to shop.

Frequently asked questions

Can Maine residents choose their electricity supplier?

Yes. Eligible customers can use Standard Offer supply or contract with a licensed competitive electricity provider. The delivery utility remains the same.

What is the Maine Standard Offer?

It is default electricity supply procured through a competitive process overseen by the Maine PUC for customers who do not select a competitive supplier.

Is the Standard Offer the total electric rate?

No. It is a supply benchmark. Delivery and other utility charges remain separate parts of the bill.

Should I switch if a CEP advertises a lower rate?

Compare the full contract, term, renewal language and fees, then verify the current offer. A small headline discount can disappear if the later pricing structure is less favorable.
