What does electricity cost a dealership in Cincinnati?
A mid-size dealership (35,000 ft²) uses roughly 532,000 kWh a year. EIA does not publish dealerships separately; CBECS’s “other retail” group averages about 15.2 kWh per square foot, and vehicle service and repair buildings about 6.1. 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 |
|---|---|---|---|---|---|---|
| 15,000 ft² | 228,000 kWh | 65 kW | 55 kW | $6,645/yr (≈2.9¢/kWh) | $25,897/yr | $1,140/yr |
| 35,000 ft² | 532,000 kWh | 152 kW | 129 kW | $15,505/yr (≈2.9¢/kWh) | $60,426/yr | $2,660/yr |
| 70,000 ft² | 1.06 million kWh | 304 kW | 258 kW | $31,011/yr (≈2.9¢/kWh) | $120,852/yr | $5,320/yr |
How these numbers are built: annual use = 15.2 kWh/ft² (EIA CBECS 2018 Table C22, 'Other retail' subcategory (CBECS puts vehicle dealerships/showrooms under retail other than mall; 2018 tables do not publish dealerships separately)). Peak demand assumes a 40% load factor; the capacity tag assumes 85% 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 dealership's bill
Showroom lighting and HVAC, lot lighting, service-bay lifts, compressors and exhaust fans, and — increasingly — EV chargers for inventory and service.
Retail hours (median about 55 a week) plus long lot-lighting hours; EV charging can add large new peaks if chargers run during business hours.
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 dealership
Most single-point dealerships are small-commercial accounts; dealer groups bid all rooftops together.
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 dealership can cut costs
- Convert lot lighting to LED with dimming after close.
- Schedule EV inventory charging overnight and cap simultaneous charging.
- Fix service-bay compressed-air leaks.
- Put showroom HVAC on occupancy schedules.
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.

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 dealership in this market, the useful starting evidence is showroom hours separately from workshop and EV charging loads. 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 dealership review should test these operating questions
- Load separation: identify showroom lighting, service bays and charging equipment. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document more EV inventory, fast charging or service-bay expansion. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
- Comparable performance: track kWh per operating day with charging sessions shown separately. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Who pays for public or inventory EV charging? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Could new chargers require different utility service or demand billing? 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 dealership | 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 more EV inventory, fast charging or service-bay expansion | 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 auto dealerships, preserve kWh per operating day with charging sessions shown separately 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 Cincinnati, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.
