What does electricity cost a restaurant in Cincinnati?
A mid-size restaurant (4,800 ft²) uses roughly 210,000 kWh a year. EIA’s 2018 Commercial Buildings Energy Consumption Survey (CBECS) puts food-service buildings at about 43.8 kWh per square foot per year — roughly three times an office. Fast-food buildings average about 62.8 kWh/ft²; sit-down restaurants about 40.6. In Cincinnati, that power is delivered by Duke Energy Ohio, and the generation portion can be bought from a PUCO-certified supplier.
On Duke Energy Ohio's default price for small businesses — about 11.36¢/kWh on the DM (first 2,800 kWh) rate (effective June 1, 2026) — the generation cost alone for the sites below looks like this:
| Illustrative site | Annual use | Est. peak demand | Est. capacity tag | Capacity cost at 2026/27 price | Generation cost at 11.36¢/kWh | Value of 0.5¢/kWh |
|---|---|---|---|---|---|---|
| 2,500 ft² | 110,000 kWh | 28 kW | 22 kW | $2,670/yr (≈2.4¢/kWh) | $12,437/yr | $548/yr |
| 4,800 ft² | 210,000 kWh | 53 kW | 43 kW | $5,126/yr (≈2.4¢/kWh) | $23,880/yr | $1,051/yr |
| 7,500 ft² | 328,000 kWh | 83 kW | 67 kW | $8,010/yr (≈2.4¢/kWh) | $37,312/yr | $1,642/yr |
How these numbers are built: annual use = 43.8 kWh/ft² (EIA CBECS 2018 Table C14, food service (mean; median 39.3; 25th-75th pct 22.9-58.5)). Peak demand assumes a 45% load factor; the capacity tag assumes 80% of that peak falls in the grid's summer peak hours. Capacity cost uses PJM's 2026/27 clearing price of $329.17/MW-day (about $120 per kW-year) before utility scaling factors. These are illustrations for sizing a decision — your own bills and interval data are what suppliers price.
What drives a Cincinnati restaurant's bill
Refrigeration is the largest electric end use (about 26% of food-service electricity in CBECS), followed by cooking (16%), cooling (11%) and ventilation (11%). Walk-in coolers and freezers run around the clock underneath the meal-period spikes.
CBECS reports a median of 72 operating hours a week for restaurants and 102 for fast food, versus 50 for all commercial buildings. Demand builds from mid-morning prep to the dinner rush, when kitchen exhaust, make-up air, cooking equipment and rooftop cooling all run together on summer evenings.
On a Duke Energy Ohio bill those loads show up in three places: the generation charge (the only part a supplier replaces), transmission and distribution charges set by PUCO-approved tariffs, and — for most business rate schedules — a demand charge on your peak kilowatts. On Duke Energy Ohio bills the generation ("supply") charges and the distribution charges are listed separately; small businesses on Rate DM see a first block of usage (the first 2,800 kWh) priced differently from later blocks.
Cincinnati specifics
Duke Energy Ohio's small-business default price (Rate DM, first 2,800 kWh) rose to about 11.36¢/kWh on June 1, 2026, so the gap between the default price and competitive offers tends to be wider in Cincinnati than in FirstEnergy territory.
Duke's DEOK capacity zone has cleared at the same price as the rest of PJM in the last three auctions, but it cleared higher than the RTO in 2024/25 ($96.24 vs $28.92 per MW-day), a reminder that zonal prices can split.
Buying electricity for one Cincinnati restaurant
Most single restaurants fall well under Ohio’s 700,000 kWh/yr “mercantile” line, so they are eligible for governmental aggregation and for small-commercial fixed-price offers. Margins are thin and budgets are monthly, which usually favors a 12–36 month fixed product with the capacity cost included, rather than index pricing.
Practical steps for a single location:
- Pull 12 months of Duke Energy Ohio bills and note the rate schedule, peak kW and any supplier already listed.
- If the site uses 700,000 kWh a year or less and never chose a supplier, check whether it was enrolled in a community aggregation program.
- Ask for fixed prices that include capacity for 12, 24 and 36 months and compare each against the default price on your actual usage.
- Make sure every quote shows broker compensation and any pass-through charges as separate lines.
Where a Cincinnati restaurant can cut costs
- Put walk-in and reach-in refrigeration on a maintenance calendar (door gaskets, condenser coils, defrost timing) — it is the one load that never shuts off.
- Interlock kitchen exhaust hoods with demand-controlled ventilation so make-up air fans slow down between rushes.
- Stagger equipment start-up at opening instead of switching every fryer, oven and rooftop unit on at once; that single habit can lower the monthly demand peak.
- Replace legacy fryers and holding cabinets with ENERGY STAR models at end of life (ENERGY STAR notes a typical electric fryer can use more than 18,000 kWh a year).
Ohio's utilities no longer offer general business efficiency rebates (PUCO ended or declined those programs in 2024–2025), so projects have to pay back on energy and demand savings alone.
FAQ
How much does electricity cost for a restaurant in Cincinnati?
At Duke Energy Ohio's small-business default generation price of about 11.36¢/kWh, a 4,800 ft² restaurant using 210,000 kWh a year would pay about $23,880 a year for generation alone, before delivery, demand charges and taxes.
Which utility serves restaurants in Cincinnati?
Duke Energy Ohio.
How much electricity does a restaurant use in Ohio?
A typical 4,800 ft² restaurant at the CBECS food-service average of 43.8 kWh/ft² uses roughly 210,000 kWh a year; fast-food units with longer hours run higher. Your own 12 months of bills are the only number that matters for pricing.
Should a restaurant pick a fixed or variable electricity rate?
Most independent restaurants choose fixed rates because food and labor costs already swing month to month. Variable or index products can pay off, but only if you can absorb a bad summer month.

Tiered billing and a changing operating day
For a Duke Energy Ohio account, ask which commercial schedule and usage blocks apply. A small first-block reference cannot price an entire month. Test the offer against the same monthly consumption profile, especially where seasonal hours change.
For a restaurant in this market, the useful starting evidence is the overnight refrigeration base load separately from lunch and dinner peaks. This is a review question, not an assumption that every local facility has the same equipment or schedule. Record what your site actually does, then explain the difference between the historical bill period and the proposed contract term.

A restaurant review should test these operating questions
- Load separation: identify refrigeration, cooking and make-up air. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document a change in meal-service hours, delivery volume or cooking fuel. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
- Comparable performance: track kWh per cover or transaction, with trading hours alongside it. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Do the refrigeration and kitchen meters belong to the same contract? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Does the offer accommodate a restaurant closure or a change of operator? Ask for the answer in the actual agreement or written offer schedule, rather than relying on a sales summary.
Evidence table for the next decision
| Question for this restaurant | Bring this evidence | What a useful answer looks like |
|---|---|---|
| Has the bill risen because of price or operations? | Same-period kWh, peak kW where billed, hours and production/occupancy records | A separation of rate, volume and demand effects; no automatic savings claim |
| Will the next term resemble the last twelve months? | The planned a change in meal-service hours, delivery volume or cooking fuel | A base case and a change case, with supplier tolerances shown |
| Are supply offers priced on equal terms? | Start dates, included components, additional fees and offer expiry | One comparison matrix that identifies every excluded or adjustable item |
| Is the site free to enroll when proposed? | Current agreement, renewal notice and actual utility confirmation | A documented timeline that avoids an unintended rollover or early-exit charge |
Portfolio review across Hamilton County
Use a separate row for every property rather than one total for the whole business. Start with Cincinnati. A common owner can negotiate a master agreement, but meters still have their own rate classes, delivery utilities, start dates and operational constraints. Do not assume that pooling bills creates a volume discount or makes a municipal meter eligible.
For restaurants, preserve kWh per cover or transaction, with trading hours alongside it at site level before rolling it into a portfolio dashboard. Otherwise a busy or continuously operating location can hide the cost of an idle one. Align contract end dates only after identifying any early-exit costs, add/delete rights and ownership-transfer provisions.

Use the private comparison and renewal tools for a first pass. They do not submit your figures. If you want help, choose “Offer comparison” or “Renewal planner” on the Ohio inquiry form, identify Cincinnati, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.
