Electricity Choices in Londonderry, NH

What changes when you choose an electricity supplier?

You choose who supplies the electricity. Your utility still delivers it. For Londonderry residents with Eversource service, Eversource continues to maintain the wires and meter, handle outages and deliver power. Changing suppliers does not change restoration priority or reliability.

Start with your bill: confirm your utility, current supplier, supply price per kWh and monthly usage. New Hampshire requires competitive suppliers to register, but their prices are not regulated. Registration is not an endorsement or a promise of savings. Read NH Department of Energy’s explanation.

Three electricity supply choices for Londonderry households

Londonderry’s town program: check your bill before shopping

You may already be receiving town-program supply. Existing competitive-supplier and net-metering accounts were not automatically enrolled at launch. Check your supplier line rather than assuming which option you have.

The program website lists a renewal supply term beginning November 1, 2026. Existing participants do not need to take action to remain enrolled. The program allows opting in or out without an early termination fee, with changes tied to meter reads. Eversource continues to send the consolidated bill. Your own existing supplier contract may have different exit terms.

What to check before signing an electricity contract

• Fixed or variable? A fixed supply price is stable during its specified term; your total bill still changes with usage and delivery charges. A variable price can change monthly. Ask how it is set and request its rate history.
• Introductory price and expiration: How long does the advertised price apply? What happens afterward?
• Renewal: Does the contract renew automatically, at what type of rate, and how will you be notified? Calendar the end date.
• Fees: Look for monthly charges, minimum-usage conditions and early termination fees. Check your current contract’s exit cost too.
• Eligibility: Confirm the offer applies to your utility and account, including new-customer restrictions.
• Billing: Ask whether you will receive one utility bill or separate supplier and utility bills.
• Promotions: Read gift-card or rebate conditions separately; do not treat them as an ongoing electricity discount.
• Renewable claims: Read the environmental disclosure and how renewable energy certificates are used. The electricity still arrives through the same grid.

Do your own research and read the complete contract before enrolling. No supplier is recommended here, and switching does not guarantee savings.

Alphabetical reference only, not an endorsement or ranking. These companies appeared on NH’s Eversource residential comparison board on October 8, 2026, and their official websites were opened. Offers may change; confirm address eligibility and the complete terms yourself. This is not an exhaustive registry.

How to switch—and where to get help

1. Find your current supplier, usage and supply price on your bill.
2. Compare the state rate board and town program with your current contract, including exit fees.
3. Save the full offer and contract before enrolling. Share account information only once you have decided to switch and verified who you are dealing with.
4. Confirm the supplier and price on subsequent bills, then calendar the renewal date.

The new supplier normally arranges the change with your utility. Switching follows meter-read timing and may take one or two months to appear on your bill. If you change your mind, act promptly: the rescission window varies by enrollment method; consult your enrollment notice and the state FAQ.

Solar, assistance and special account situations

If you have net metering, ask how a supply change affects export credits before enrolling. Do not assume credits remain identical. New Hampshire’s Electric Assistance Program benefits continue to apply to supply and delivery with competitive supply, according to the state FAQ; confirm your account-specific details.

Does a supplier change who handles outages?

No. Contact your delivery utility for outages, wires or meter issues. Supplier selection changes supply arrangements, not the utility network.

What if an enrollment or charge looks wrong?

Contact the supplier and your utility promptly, retain the contract and bill, and use NH Department of Energy’s consumer guidance to find the appropriate assistance channel. Do not assume a sales caller represents your utility.

Can I return to another supply option?

Yes, but review your current contract’s termination terms and meter-read timing first. Londonderry’s town program publishes its own opt-in/out process; individual supplier terms may differ.
