Ohio Fixed vs Variable Electric Plans: Which Fits Your kWh

If you live or run a small business in Ohio, you have probably seen offers for a "fixed" cents-per-kWh rate and others advertised as "variable" or "indexed." The label on the postcard is only half the story. Your utility still delivers power over local wires; what you are choosing is who sells you the electrons and whether that supply price is locked in or allowed to move. Match that choice to how many kilowatt-hours (kWh) you use, how predictable your usage is, and how much month-to-month bill swing you can tolerate.

Two charges on one bill: supply vs delivery

Ohio restructured its electricity market so generation can be competitive while distribution stays regulated. On a typical bill you will see delivery charges from your utility (poles, wires, reliability) and generation charges from either your utility's default service or a competitive retail supplier you selected.

The Department of Energy describes this split plainly: a ¹ means one provider handles supply and delivery together; an unbundled rate means supply and delivery can come from different providers, sometimes on one consolidated bill and sometimes on two. In Ohio's competitive setup, most shoppers are comparing the supply portion—the price multiplied by your kWh—while delivery riders and fixed customer charges still apply either way.

That matters because a great supply rate does not erase delivery costs, and rising fixed monthly customer charges can blunt savings even when your per-kWh supply price looks low. ² that bills have two parts: energy use (kWh) and mandatory fixed charges that hit before the meter spins—charges some utilities want to increase, which can penalize households that use less power.

What "fixed" and "variable" actually mean

Fixed-rate supply (for the contract term): You agree to a stated price per kWh for generation/supply for a defined period—often 6, 12, 24, or 36 months. If you use more kWh, you pay more; if you use fewer, you pay less—but the rate itself does not change with wholesale markets during the term.

Variable-rate supply: The per-kWh price can change, sometimes every billing cycle, often tied to an index or market conditions. Federal ³ says shoppers need to know not only price but whether it is fixed or variable for the contract term, plus duration, early-termination penalties, and other fees—because you may not sign a paper contract in person; disclosures substitute for the old monopoly tariff sheet.

Variable plans are not inherently scams, but they behave differently. Research summarized by ⁴ on competitive markets warns that variable rates can change as often as monthly, may require you to check the supplier's website for the current price, and can spike when wholesale power prices jump—making budgets harder even if your kWh use is flat. Suppliers on fixed rates, by contrast, usually hedge or contract ahead to honor the price they quoted you.

Read the fine print on "fixed." Some markets have seen plans marketed as fixed while contract language allows monthly adjustments based on fuel costs. Treat "fixed" as fixed only if the disclosure says the energy price stays constant for the full term with no periodic pass-through adjustments.

Ohio by the numbers: choice is the norm

Ohio is among ⁵, with ongoing policy work around default service and transitions off capped provider-of-last-resort rates.

Recent federal data underline how large competitive supply has become:

Source: ⁶.

Roughly three-quarters of Ohio's retail megawatt-hours flow through competitive supply arrangements—a strong signal that if you have not compared your generation rate lately, you are in the minority.

For household planning, EIA's 2023 state rankings show Ohio residential customers averaging about 4,204 kWh per year (~350 kWh/month)—useful for translating a quoted ¢/kWh into dollars. At 11.29¢/kWh blended average, a household right at that usage might spend on the order of $470/year on electricity before fees and delivery—but your supply offer can be above or below the utility's price-to-compare depending on market timing. See ⁷.

The benchmark: price-to-compare and default service

If you do nothing, your utility's Standard Service Offer (SSO)—default generation—still supplies your kWh. Utilities periodically procure that power and publish a price-to-compare so you can see whether a retail offer beats default supply.

AEP Ohio's recent PUC filings illustrate the concept: a residential bill might state that the standard service rate is, for example, 10.5¢/kWh, and that a competitive supplier must beat that rate for the same usage to save money on generation. The underlying lesson is stable: compare supplier ¢/kWh to the SSO price on your bill, not to last year's teaser mailer. ⁸.

Ohio policymakers also expect suppliers to use bill messaging space to show when introductory fixed rates expire—more on that below.

When a fixed rate fits your kWh profile

Fixed supply tends to win for households and small businesses that want predictable budgeting and can commit to a term.

Consider fixed if:

• Your usage is steady year-round (within ~10–15% month to month). You use kWh as a predictable input; locking the rate removes one unknown.
• You are risk-averse about energy markets. Wholesale power can move with fuel costs, weather, and demand. A fixed contract shifts market risk to the supplier for the contract window.
• You are signing during a dip relative to the SSO price-to-compare. A fixed offer below the benchmark locks that spread for the term—even if variable market rates later fall.
• You want protection from summer spikes while running A/C. Variable rates can rise when demand peaks; fixed rates do not adjust mid-contract.

Work the math explicitly. If a supplier quotes 8.9¢/kWh fixed for 12 months and your home uses 900 kWh in a summer month, supply cost is about $80.10 for that month before delivery and fees. If you instead paid 11.5¢ variable that month, the same 900 kWh costs $103.50—a $23 swing in supply alone. Multiply swings across June–August and fixed plans earn their keep for high summer kWh homes.

Fixed is weaker if you might move or switch before the term ends. Early-termination fees are common; federal guidance lists termination penalties among the terms that must be clear in competitive markets.

When variable might make sense—and the risks

Variable supply can work if you actively manage the contract and tolerate bill movement.

Variable may fit if:

• You watch markets and will read each bill or supplier notice when the rate resets.
• Your usage is flexible—you can cut load when you see a high price coming.
• You plan to switch quickly if the rate jumps.
• Wholesale prices are soft and the variable offer starts well below fixed alternatives—understanding that the spread can reverse.

The ⁹ notes suppliers blend long-term contracts, short-term purchases, and hedging to serve customers; variable offers pass more spot-market exposure through to you. When spot prices spike, variable customers can see rapid increases during summer peaks or supply crunches—while fixed customers keep the same energy price until renewal.

Do not confuse variable supply with time-of-use delivery rates. Optional time-varying delivery programs are a separate decision from competitive variable supply contracts.

Ohio's 2025 twist: introductory fixed rates that flip to variable

Ohio House Bill 15 added consumer-notice rules that matter if your "fixed" plan is only an introductory period. Under the new law, if a retail supplier offers a fixed introductory rate that converts to a variable rate when the intro period ends, the supplier must:

1. First notice (60–90 days before expiration): expiration date, pointer to the PUCO Apples to Apples comparison site, and (for electricity) mention of the SSO price-to-compare on your bill.
2. Second notice (15–45 days before expiration): the same information plus the specific initial variable rate you will pay when the contract converts.
3. Annual notice if you remain on variable after conversion: you are on a variable rate and other fixed offers exist.

Notices go by U.S. mail unless you gave verifiable consent for email. ¹⁰.

PUCO implementing rules largely track the statute and define which small commercial customers receive the same protections as residential shoppers. ¹¹.

Practical takeaway: A teaser "fixed" rate that auto-renews into variable is not the same as a multi-year fixed contract. Calendar the expiration before the first notice arrives. If the post-intro variable rate is high, your kWh spending can jump even if usage is unchanged.

How to compare plans for your kWh—not your neighbor's

1. Pull 12 months of kWh from bills or your utility portal. Seasonality beats guessing.
2. Find the price-to-compare on your current bill for the SSO generation rate.
3. Normalize offers to total ¢/kWh for supply, noting whether the rate is fixed for the full term or intro-fixed.
4. Add delivery and fixed charges—a low supply rate still sits on top of regulated delivery and monthly customer charges.
5. Check contract length, ETF, and renewal terms (auto-renew variable vs fixed).
6. Use Ohio's Apples to Apples comparison (referenced in HB 15 notices) for side-by-side offers in your utility territory.

Federal guidance also recommends showing average prices at several typical usage levels (500, 1,000, 2,000 kWh) because a plan that looks cheap at one benchmark can lose at your actual profile. If a marketer quotes only a teaser usage level, run your own numbers.

Small-business wrinkles

Commercial meters often have higher peak demand (kW) charges on the delivery side even when supply is competitive. ¹ notes demand charges based on your monthly peak kW and separate fixed monthly charges determined by rate schedule—not by kWh—so supply choice alone may not dominate the bill.

HB 15 extended several residential-style consumer protections to small commercial electric customers under Ohio's statutory definition tied to nonresidential tariffs. If you are a shop, church, or small office, read notices as carefully as a homeowner would.

Regulated markets elsewhere (quick context)

Not every U.S. reader can shop supply. In regulated states, one utility sets bundled rates; "fixed vs variable" may refer to utility rate schedules or budget billing, not competitive contracts. Ohio and other ¹² are the audience for supplier fixed/variable decisions; elsewhere, focus on efficiency, rate schedules, and utility programs.

Decision checklist

Bottom line: Ohio's competitive market makes supply price a choice, and your kWh profile is the calculator input. Fixed rates trade flexibility for predictability—usually the better fit for steady-use homes and summer-heavy A/C load. Variable rates can save when markets are soft and you will monitor them, but they expose you to price spikes with no usage change. Treat any "fixed" that converts to variable as a countdown, not a destination—and compare every offer to the SSO price-to-compare using your actual annual kWh, not a postcard average.
