Maine Electricity Suppliers: CMP vs Versant Power Standard Offer and Competitive Supply (2026)

Maine has a deregulated electricity supply market split between two utility territories: Central Maine Power (CMP) and Versant Power. In both, the utility delivers your electricity but you can choose where the supply (generation) comes from — either the state-set Standard Offer or a competitive electricity provider. Understanding which territory you’re in and how the Standard Offer is priced is the key to shopping smart in 2026.

The Two Utility Territories: CMP and Versant

Central Maine Power serves the southern and central part of the state — Portland, Lewiston, Augusta, and most of the population — with roughly 650,000 customers. Versant Power (formerly Emera Maine / Bangor Hydro) serves the Bangor area and much of eastern and northern Maine. Both are regulated transmission-and-distribution utilities. They own the wires and handle delivery, billing, and outages, but they do not profit from the electricity commodity itself.

Your delivery charges depend on which territory you’re in and are set by the Maine Public Utilities Commission (MPUC). They’re the same no matter which supplier you use — competition only affects the supply portion.

How the Maine Standard Offer Works

Maine’s Standard Offer is unusual and worth understanding. The MPUC runs a competitive bid process to select Standard Offer providers for each utility’s residential and small-business class. The winning bidders supply default power at the contracted price, and that price becomes the Standard Offer rate everyone defaults to if they don’t shop. New Standard Offer rates typically take effect at the start of each year, and the year-over-year changes can be dramatic depending on wholesale gas and capacity prices.

Because the Standard Offer is procured competitively by the state, it’s often a genuinely competitive benchmark — in some years competitive suppliers struggle to beat it, and in others they offer real savings or rate stability. Always compare against the current Standard Offer rate for your specific territory and customer class.

Competitive Electricity Providers (CEPs)

Maine licenses competitive electricity providers that can supply your generation instead of the Standard Offer. These suppliers offer fixed-rate contracts, green/renewable plans, and various term lengths. The pitch is usually rate stability (locking a fixed price) or a renewable energy product. As in every deregulated state, the supplier handles the commodity while CMP or Versant continues to deliver power and respond to outages.

Maine regulators have at times scrutinized residential competitive suppliers because some customers ended up paying more than the Standard Offer over time, especially on variable rates. The lesson: only sign clearly-stated fixed-rate contracts, and avoid variable plans with introductory teaser pricing.

Reading Your Maine Electricity Bill

Your bill from CMP or Versant separates two main components: delivery (the regulated charge for using the utility’s wires) and supply (the generation charge, either Standard Offer or your chosen CEP rate). When you compare offers, you’re only comparing the supply per-kWh price. The delivery charge is fixed regardless of supplier, so a supplier advertising a low “rate” is only talking about the supply portion — not your whole bill.

Practical Shopping Strategy for 2026

• Identify your territory. CMP for southern/central Maine; Versant for the Bangor region and the north/east.
• Find the current Standard Offer rate for your territory and customer class — it’s your price to compare.
• Only consider fixed-rate competitive offers that clearly beat the Standard Offer or provide rate stability you value.
• Avoid variable-rate plans and watch for early termination fees and post-introductory rate resets.
• Consider a green plan if renewable sourcing matters to you, but compare the premium against the Standard Offer.

Net Energy Billing and Solar in Maine

Maine has an active solar market supported by net energy billing (NEB), which credits customers for the electricity their rooftop or community solar systems send back to the grid. Both CMP and Versant administer NEB, and the program has fueled rapid growth in community solar farms across the state. If you can’t install panels yourself, you can often subscribe to a community solar project and receive bill credits — effectively a green plan that also reduces your delivery-side costs. This interacts with your supply choice: NEB credits apply to your utility bill regardless of whether you’re on the Standard Offer or a competitive supplier. So a Maine household can pair a community solar subscription with whichever supply option is cheapest, stacking savings from both. As with any solar arrangement, read the subscription terms carefully and confirm how credits are valued before committing.

Should Maine Residents Switch Suppliers?

Because Maine’s Standard Offer is competitively bid, switching isn’t always a slam dunk the way it can be in Texas or Ohio. In years when the Standard Offer is high, a fixed competitive contract can lock in savings and protect you from further increases. In years when it’s low, staying on the Standard Offer is often the cheapest option. The disciplined approach is to check the spread annually when the new Standard Offer takes effect and only switch when the math clearly favors it. Compare current Maine offers below.

Frequently Asked Questions

Who delivers my electricity in Maine?

Either Central Maine Power (CMP) in southern and central Maine, or Versant Power in the Bangor area and eastern/northern Maine. They deliver power and handle outages regardless of your supplier.

What is the Maine Standard Offer?

It’s the default electricity supply price, set through a competitive bid run by the Maine Public Utilities Commission. If you don’t choose a competitive supplier, you’re automatically on the Standard Offer for your territory and customer class.

Can I choose my electricity supplier in Maine?

Yes. Maine licenses competitive electricity providers (CEPs) that can supply your generation instead of the Standard Offer. CMP or Versant still delivers the power and bills you.

Is it cheaper to switch from the Maine Standard Offer?

Sometimes. Because the Standard Offer is competitively procured, it’s often hard to beat. Compare a fixed competitive rate against the current Standard Offer each year and switch only when the spread clearly favors it.

Why do Maine regulators warn about competitive suppliers?

Some residential customers, particularly on variable-rate plans, paid more than the Standard Offer over time. Stick to clearly-stated fixed-rate contracts and avoid variable teaser-rate plans.

Does switching suppliers affect reliability in Maine?

No. CMP and Versant Power own the grid and handle all delivery and outage restoration. Switching suppliers only changes the supply portion of your bill, not your service.
