Quick Verdict
For most New Hampshire households shopping in the state’s deregulated electricity market, choosing a fixed-rate plan from a competitive retail energy provider is the move that protects your budget year-round — especially if you live in a high-usage home or want to avoid the volatility of default utility rates. If green energy matters to you, a renewable electricity plan from a competitive supplier gives you both price predictability and environmental credibility without the trade-off of unpredictable bills. The nuance is this: if you’re a low-usage renter who’s rarely home, the default service from your utility distribution company might actually be fine — but most homeowners should be comparing options actively, not passively accepting the default rate.

What We’re Comparing and Why It Matters
New Hampshire operates in a deregulated electricity market, which means you have the right to choose who supplies your electricity — separate from the utility company that actually delivers it over the wires. Your distribution utility (most likely Eversource or Liberty Utilities, depending on where you live) always handles the poles, lines, and infrastructure. What you can switch is the supply side, which shows up as a line item on your bill.
This distinction matters because most people never realize they’re passively accepting a default rate — called “default service” — set by the Public Utilities Commission. That rate changes periodically and can rise sharply when energy markets tighten, particularly in New England winters when natural gas demand spikes.
The real decision factors in this comparison:
- Rate structure (fixed vs. variable): Do you want certainty or flexibility?
- Contract length and termination fees: Are you locked in, and what does it cost to exit?
- Green energy credibility: Are claims backed by verifiable Renewable Energy Certificates (RECs)?
- Total bill impact: Supply rate is only part of your bill — distribution charges from your utility are unavoidable regardless of supplier.
- Customer service: When something goes wrong, who actually picks up?
What’s largely marketing noise: supplier branding, loyalty points programs, and vague “savings” claims that don’t specify the benchmark rate they’re comparing against.

Detailed Analysis of Each Option
Competitive Fixed-Rate Electricity Suppliers
These are retail energy suppliers licensed by the New Hampshire PUC to sell electricity supply in the state. They purchase power on wholesale markets and offer it to you at a set per-kWh rate for a defined contract term — typically ranging from six months to two or three years.
What they do well: The primary benefit is price certainty. If you sign a fixed-rate plan and wholesale electricity prices jump over winter (which happens regularly in New England), your supply rate doesn’t move. For homeowners with electric heat or high monthly usage, this protection is genuinely valuable.
Where they fall short: The fixed rate is only as good as the rate you locked in. If you sign during a market peak and wholesale prices drop, you’re stuck overpaying until your contract expires. Also, watch for early termination fees — some contracts charge a flat fee, others charge per remaining month, and those costs can be substantial if your circumstances change.
Onboarding: Switching is handled entirely through paperwork (or online enrollment) with your chosen supplier. Your utility automatically updates your account — there’s no service interruption, no technician visit, and your bill structure stays the same. The switch typically takes one to two billing cycles.
—
Variable-Rate Electricity Suppliers
Variable-rate plans adjust monthly based on wholesale market conditions. Some suppliers reset rates monthly; others can change with less notice depending on contract terms.
What they do well: No long-term commitment means you can switch again whenever you find a better option. If you’re a renter, between homes, or simply don’t want to think about contract expiration dates, month-to-month flexibility has real appeal.
Where they fall short: Variable rates can spike badly in winter, and New England is one of the most price-volatile electricity regions in the country due to natural gas pipeline constraints. A rate that looked reasonable in September can look alarming in January. If your usage is high, this volatility amplifies into significant bill swings.
—
Renewable and Green Energy Suppliers
Several suppliers offer plans where your electricity supply is matched with Renewable Energy Certificates (RECs) from wind, solar, or hydro sources. Some source electricity directly from regional renewable generators; others purchase RECs from a broader market.
What they do well: For households committed to reducing carbon footprint, these plans provide verifiable documentation that your electricity consumption is offset by renewable generation. Many are competitively priced against standard fixed-rate plans — the premium, if any, is often modest.
Where they fall short: Not all “green” claims are equal. Ask specifically whether RECs come from New England generators or are sourced from distant markets (which reduces the local grid impact). Also, some renewable plans are variable-rate, which carries the same volatility risk described above.
—
Default Utility Service (Eversource / Liberty Utilities)
If you’ve never switched suppliers, this is what you’re on. Your utility files a default service rate with the PUC, which is reviewed and adjusted periodically based on wholesale electricity procurement.
What it does well: Absolute simplicity — no sign-up, no comparison shopping, no contract management. For people who genuinely don’t want to engage with the energy market, it’s the zero-effort option.
Where it falls short: Default rates are adjusted on a schedule, and those adjustments can be jarring. You also have no negotiating power and no rate lock. When wholesale markets move against consumers — as they have during periods of regional energy stress — default rates follow.
—
Community Aggregation Programs
Some New Hampshire municipalities negotiate electricity supply contracts on behalf of their residents collectively. If your town participates, you may be automatically enrolled in a community aggregation program that offers a negotiated fixed rate, sometimes with a green energy component.
What they do well: Aggregation programs can deliver solid rates because they pool purchasing power. The sign-up friction is essentially zero for residents of participating towns.
Where they fall short: Program availability is limited to specific municipalities. Terms vary by town, and residents need to verify details directly with their local program administrator. If you’ve moved recently, check whether your current address is covered.

Head-to-Head on What Matters Most
Rate Certainty vs. Flexibility
Fixed-rate plans win if you have high monthly usage, own your home, or plan to stay put for at least a year. Variable-rate plans win if you’re in a short-term living situation or are confident you’ll actively monitor and switch when rates rise. Most consumers should lean toward fixed-rate — the downside of a winter rate spike on a variable plan typically outweighs the upside of occasional savings.
Green Energy Credibility
Not all renewable labels are equivalent. When comparing suppliers, ask:
- Are RECs sourced from New England generators or national markets?
- What percentage of supply is renewable — 50%, 100%?
- Is the plan independently verified by a certification body?
100% REC-backed plans from regional generators are the gold standard. Vague “green” branding without REC documentation is essentially marketing.
Contract Terms and Exit Costs
This is where the fine print catches people. Before signing any supply agreement, confirm:
- Exact contract length
- Early termination fee structure (flat fee vs. per-month)
- Auto-renewal policy (does it roll into a new term, or revert to variable?)
Auto-renewal is the most common trap — your fixed-rate contract expires, you don’t notice, and you’re suddenly on a variable rate or rolled into a new term without realizing it.
Customer Support
Your distribution utility handles outages, billing disputes that affect the delivery portion, and meter reads. Your electricity supplier handles the supply rate on your bill. When you have a complaint, you need to know which entity to contact. The New Hampshire PUC is your escalation point if either your utility or supplier fails to resolve a legitimate dispute.

Who Should Choose What
If you’re a homeowner with consistent high monthly usage → go with a competitive fixed-rate supplier. Price certainty protects you from New England’s notorious winter rate volatility, and the savings opportunity over default service is most meaningful at higher consumption levels.
If you rent or expect to move within a year → consider a variable-rate plan with no early termination fee, so you can exit cleanly. Just monitor your rate actively, especially heading into heating season.
If reducing your carbon footprint is a priority → choose a renewable supplier offering 100% REC-backed electricity, and verify the RECs are sourced from regional generators where possible.
If you want the simplest possible experience → check whether your municipality offers a community aggregation program. If it does, you likely get a negotiated rate without lifting a finger.
If you’re genuinely hands-off and low-usage → default utility service isn’t a disaster, but you should at least compare your current rate against available supplier offers periodically. The comparison takes less than ten minutes.

What to Watch Out For
Promotional pricing that doesn’t last. Some suppliers offer an attractive introductory rate for the first few months, then shift to a higher variable rate. Read the full contract before signing, not just the headline number.
Vague savings claims. If a supplier says “save up to X% compared to default service,” ask compared to which rate, over which period. Benchmarks can be cherry-picked.
Auto-renewal into unfavorable terms. Set a calendar reminder for 60 days before your contract end date. That’s typically your window to switch without penalty.
RECs without verification. A supplier calling a plan “green” without citing REC sourcing or third-party certification is a yellow flag.
Third-party marketing calls. Some suppliers use aggressive door-to-door or telemarketing tactics. You’re never obligated to switch on the spot — take the materials, compare independently, and sign up on your own timeline.

FAQ
Is New Hampshire a deregulated electricity state?
Yes. New Hampshire operates a deregulated electricity supply market, meaning you can choose your electricity supplier separately from the utility that delivers power to your home. Your distribution utility — typically Eversource or Liberty Utilities — remains responsible for the wires and infrastructure regardless of which supplier you choose.
Will switching electricity suppliers affect my service reliability?
No. Your utility still delivers electricity over the same infrastructure. Switching suppliers only changes the supply charge on your bill — there’s no change to reliability, no service interruption, and no technician visit required.
What happens when my electricity supply contract expires?
It depends on your contract terms. Many suppliers auto-renew into a new fixed-rate term or convert you to a variable rate. Set a calendar reminder before your contract end date so you can actively choose your next plan rather than defaulting to whatever your supplier assigns.
How do I verify a supplier’s green energy claims?
Ask the supplier for documentation of their Renewable Energy Certificates (RECs) and whether those RECs are sourced from New England generators. You can also check whether the supplier participates in a recognized certification program. Vague green branding without REC documentation should be treated skeptically.
Are there early termination fees if I want to switch?
It depends on your contract. Fixed-rate contracts often include early termination fees — either a flat amount or a per-month charge for the remaining term. Variable-rate and month-to-month plans typically don’t. Always confirm the ETF structure before signing any supply agreement.
Who do I contact if I have a complaint about my electricity supplier?
Start with the supplier’s customer service. If that doesn’t resolve the issue, the New Hampshire Public Utilities Commission (PUC) is the regulatory body that oversees both utilities and competitive suppliers in the state and handles formal complaints.
