How to Compare Electricity Suppliers Online: A Step-by-Step Guide for 2026

Comparing electricity suppliers online is easier than most people expect — the entire process takes 10–15 minutes, requires nothing more than your utility bill and your ZIP code, and can result in hundreds of dollars in annual savings if you’re in a deregulated electricity state. This guide walks through exactly how to compare electric suppliers, what to look for, what to avoid, and how to get the best possible rate for your home or business.

Step 1: Confirm You’re in a Deregulated State

Before comparing suppliers, verify that you live in a state where electricity deregulation applies to residential customers. The major deregulated states are Texas, Illinois, Pennsylvania, New York, New Jersey, Ohio, Connecticut, Maryland, Massachusetts, Maine, New Hampshire, Rhode Island, and the District of Columbia. Michigan, Virginia, and a few others have partial deregulation.

If your state is not on this list, you cannot choose your electricity supplier — your utility is the sole provider and rates are set by the state public utilities commission. If you’re in a deregulated state, read on.

Step 2: Pull Your Most Recent Utility Bill

You’ll need two things from your utility bill:

Your account number. This is required when you enroll with a new supplier. It’s typically a 10–12 digit number on your bill’s header or account summary section.

Your current supply rate in cents per kWh. Look for the line item labeled “Supply,” “Generation Service,” “Basic Service,” “Competitive Transition Assessment,” or similar. This number — in cents per kWh — is what you’re trying to beat. Do NOT use the total bill rate or the combined delivery + supply rate as your benchmark. Only the supply-side rate is changeable.

Also note your average monthly kWh usage (usually shown in a 12-month bar graph on the back of the bill). You’ll use this to estimate savings.

Step 3: Use a Comparison Tool or Visit Suppliers Directly

There are two ways to compare electricity suppliers:

Comparison websites (aggregators): Sites like Choose Energy, SaveOnEnergy, and EnergyBot aggregate offers from multiple licensed suppliers and let you filter by price, contract length, renewable content, and more. These are the fastest way to see the market at a glance. Enter your ZIP code, confirm your utility, and you’ll get a list of available plans sorted by rate.

Direct supplier websites: Some suppliers don’t list on aggregators and instead sell directly. If you have a preferred supplier (perhaps from a prior positive experience), check their website directly. Keep in mind that without aggregator comparison, you’ll need to shop multiple supplier sites independently to compare.

For most customers, starting with a comparison aggregator is faster and gives a more complete market view.

Step 4: Know What to Compare (And What to Ignore)

Supply rate (cents per kWh) — MOST IMPORTANT: This is the core number. Compare it directly to your current supply rate from Step 2. Lower is better. Make sure you’re comparing apples to apples — both numbers should be supply-only rates, not all-in bill rates.

Contract term: Most plans come in 6, 12, 18, or 24-month terms. Longer fixed-rate terms give you more price certainty but less flexibility. Shorter terms let you re-shop sooner. Match the term to your planning horizon.

Early termination fee (ETF): The fee you’ll pay if you cancel before the contract ends. ETFs range from $0 to $150+. Plans with no ETF give you flexibility to switch if a better rate appears. Always know the ETF before enrolling.

Introductory rate vs. ongoing rate: Some plans advertise a low introductory rate that rolls to a higher variable rate after 3–6 months. Read the fine print. Make sure the rate you’re comparing is what you’ll actually pay for the full contract term — not just a teaser period.

Renewable content: If green energy matters to you, look for plans backed by RECs (Renewable Energy Certificates) from wind, solar, or hydro sources. These plans often carry small premiums over standard plans but have become increasingly cost-competitive.

What to ignore: “Estimated annual savings” projections are based on assumptions about your usage and often compare against inflated benchmark rates. Don’t make your decision on the savings estimate — make it on the per-kWh rate vs. your actual current rate.

Step 5: Read the Electricity Facts Label (EFL)

Before enrolling with any supplier, click through to read the Electricity Facts Label (EFL) or Product Disclosure Label — a standardized disclosure document required by most deregulated states. The EFL contains the precise rate for each billing period, the contract length, all fees (including ETF), auto-renewal terms and conditions, the percentage of electricity from renewable sources, and customer service contact information.

Reading the EFL before enrolling takes 3–5 minutes and can prevent unpleasant surprises. Pay particular attention to the auto-renewal clause — many plans automatically renew at a variable rate unless you cancel within a specific window before expiration.

Step 6: Verify the Supplier Is Licensed

Every legitimate competitive electricity supplier must be licensed by your state’s public utility commission (PUC) or public service commission (PSC). Before enrolling, verify the supplier’s license.

In Texas, check the PUCT’s licensed REP list at powertochoose.org or the PUCT website. In Pennsylvania, check PAPowerSwitch.com. In New York, check the NYPSC’s licensed ESCO list. In Ohio, check the PUCO website. Other states maintain similar public registries. If a supplier is not on your state’s licensed list, do not enroll — they have no consumer protection standing and you’ll have no recourse if something goes wrong.

Step 7: Enroll With Your Chosen Supplier

Once you’ve selected a plan, navigate to the supplier’s enrollment page (or call their 800 number). Enter your utility account number, service address, and contact information. Confirm the rate and contract terms. Authorize the switch (typically by checking a box or providing an e-signature). Receive a confirmation email with your contract details.

The switch itself happens on the back end between your new supplier and your utility — you don’t need to call your utility or do anything else. Most switches take effect within 1–2 billing cycles.

Step 8: Verify Your First Post-Switch Bill

After your supplier switch takes effect, check your next utility bill carefully. You should see your utility’s delivery charges (unchanged from before), a new line item showing your competitive supplier’s name and supply rate, and the total bill incorporating both components.

If the supply rate on your bill doesn’t match what you agreed to when enrolling, contact your supplier immediately and reference your enrollment confirmation. Keep the EFL and confirmation email — you’ll need them if there’s a discrepancy.

Common Mistakes When Comparing Electricity Suppliers

Comparing total bill rates instead of supply-only rates. The total bill includes delivery, taxes, and fees that don’t change when you switch. Only the supply rate is comparable between suppliers and your current utility rate.

Ignoring the auto-renewal clause. If your plan auto-renews to a variable rate and you miss the cancellation window, you could end up on a higher rate for months before you notice. Set a calendar reminder 45 days before contract expiration.

Choosing based on the teaser rate alone. Introductory rates are marketing tools. A plan with a 3-month intro rate of 8 cents followed by a variable rate that averages 15 cents is worse than a straightforward 12-month fixed rate of 12 cents. Read the full contract terms.

Not accounting for the ETF when switching mid-contract. If you switch away from your current competitive supplier before your contract expires, you may owe an ETF. Calculate the savings from the new rate over the remaining contract period and deduct the ETF to see if switching still makes financial sense.

Using outdated comparison data. Supplier rates change frequently — sometimes weekly. A rate you saw quoted 2 weeks ago may no longer be available. Always compare on the day you plan to enroll, not days or weeks earlier.

How Often Should You Compare Electricity Rates?

The right answer is: whenever your current contract is approaching expiration (60–90 days out), and whenever there’s a major market event that might affect rates (gas price spikes, regulatory changes, new supplier entrants). For most customers, an annual comparison at contract renewal is sufficient. Making rate shopping a 10-minute annual habit is the simplest way to stay at a competitive price.

Frequently Asked Questions

Is it safe to switch electricity suppliers online?

Yes, if you’re enrolling with a licensed supplier through a reputable comparison platform. The major comparison sites vet suppliers for licensure. Your utility account information (account number and service address) is the same kind of information you’d share with any service provider. Read the EFL, check the supplier’s license, and keep your confirmation email.

How do I know if I’m getting the best rate?

Compare at least 3–5 plans from different suppliers, filtered for fixed rates with comparable contract terms. The lowest fixed rate from a licensed supplier, with no large ETF, for a term that fits your plans, is typically the best deal. Don’t over-optimize for a rate that’s 0.1 cents lower if it comes with a large ETF or problematic auto-renewal terms.

What if I move during my contract?

Most competitive suppliers have a moving clause in their contracts — you can cancel penalty-free if you move to a service area where the supplier doesn’t operate. If you move within the same supplier’s territory, your contract typically transfers to your new address. Check your contract’s moving terms before signing.

Can I compare suppliers if I have solar panels?

Yes. Net metering arrangements are with your utility and don’t change when you switch suppliers. You’ll still receive net metering credits for excess solar generation from your utility, while the energy you draw from the grid will be supplied at your competitive supplier’s rate. The combination can be particularly cost-effective.

The Bottom Line on Comparing Electricity Suppliers

Comparing electricity suppliers online is one of the more efficient personal finance moves available in deregulated markets. The barrier is low (10–15 minutes, no fees), the downside is minimal (the process is reversible and regulated), and the potential upside — particularly for high-usage households or businesses — is substantial. The main requirement is developing the habit of comparing at contract renewal rather than letting your plan auto-renew to a potentially higher rate. Use the steps above as your standard process and you’ll rarely pay more than you need to for electricity.
