Hamilton County Restaurant Electricity: Multi-Site Guide

Confirm the applicable business rate, components and effective dates on your bill before comparing an offer. How to establish your benchmark.
Can several restaurants in Hamilton County share one electricity contract?
Every investor-owned-utility site in Hamilton County is on Duke Energy Ohio, so one supplier can price the whole portfolio on a single rate structure.
Rural sites served by an electric cooperative — Butler Rural Electric Cooperative — are in the same position.
Portfolio math for restaurants in Hamilton County
Take an illustrative operator with three smaller and two mid-size locations (2,500 ft² and 4,800 ft²):
| Portfolio measure | Estimate |
|---|---|
| Combined annual use | 749,000 kWh |
| Combined capacity tags | about 152 kW |
| Capacity cost at 2026/27 price ($329.17/MW-day) | about $18,262 a year |
| Illustrative tags at the 2024/25 RTO reference ($28.92/MW-day) | about $1,604 a year |
| Value of each 0.5¢/kWh in supply price | about $3,745 a year |
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.
At that combined size the operator is a meaningful account for suppliers, even if each location on its own is below Ohio's 700,000 kWh-a-year “mercantile” line. Each account's aggregation eligibility is still judged site by site.
Utilities and default prices across Hamilton County

Structuring a multi-site contract
- Master agreement with site schedules. Sign one agreement and list each location on a schedule, so opening or closing a restaurant is an amendment, not a new negotiation.
- Add/delete rights. Ask for the right to add new locations at the contract price (or a formula) and to remove closed locations without penalty up to a set share of volume.
- Aggregate bandwidth. Measure usage tolerance across the whole portfolio rather than meter by meter, so one busy site doesn't trigger true-up charges.
- Co-terminous end dates. Put every site on the same end date so the next bid covers the full portfolio.
- Aggregation exits. Locations at 700,000 kWh a year or less may be in a community aggregation program; confirm how each will be moved to the new supplier and whether any exit terms apply.
Operating issues specific to restaurants
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.
Across a portfolio, the biggest wins usually come from standardizing settings and comparing sites against each other. For restaurants, that means:
- 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.
Restaurants in municipal-utility cities (for example Hamilton, Westerville or Cuyahoga Falls) cannot choose a supplier; the savings there come from demand management and equipment, not procurement.
FAQ
Can a restaurant operator buy electricity for all Hamilton County locations together?
Yes. A supplier can put every shoppable site under one agreement, all priced on Duke Energy Ohio's rate structure.
Which Hamilton County locations can't be included?
Sites served by electric cooperatives (Butler Rural Electric Cooperative) generally can't be enrolled with a retail supplier.
Why did my restaurant’s electric bill go up even though we sold less?
Generation and capacity costs rose sharply in 2025–2026 (PJM capacity prices went from $28.92 to over $325 per MW-day), and delivery riders changed. A bill review separates price changes from usage changes.

Do not confuse Hamilton County with Hamilton city
This page concerns Hamilton County, including Cincinnati. The City of Hamilton is in Butler County and has a municipal electric utility. Match each service address and bill utility; never infer Duke service from the word Hamilton alone.
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.

The local guide is a starting map, not an address-level enrollment determination. Keep utility bills and account identifiers in the private document package, not the initial website inquiry. The Ohio bill guide explains how to identify the delivery and supply companies.
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.
Turn this into a review request
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 Hamilton County, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.

Historical capacity comparison note: $28.92/MW-day is the 2024/25 RTO reference, not the 2024/25 DEOK zonal result. Duke’s DEOK zone cleared higher that year. A wholesale comparison is not the account’s retail tariff or a supplier quote. See PJM auction records.
