What does electricity cost a warehouse in Cincinnati?
A mid-size warehouse (200,000 ft²) uses roughly 1.06 million kWh a year. CBECS 2018 puts non-refrigerated warehouses at about 5.3 kWh per square foot per year and distribution/shipping centers at about 5.9 — but the square footage is so large that the total bill is significant. 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 |
|---|---|---|---|---|---|---|
| 50,000 ft² | 265,000 kWh | 67 kW | 54 kW | $6,461/yr (≈2.4¢/kWh) | $30,099/yr | $1,325/yr |
| 200,000 ft² | 1.06 million kWh | 269 kW | 215 kW | $25,846/yr (≈2.4¢/kWh) | $120,398/yr | $5,300/yr |
| 600,000 ft² | 3.18 million kWh | 807 kW | 645 kW | $77,538/yr (≈2.4¢/kWh) | $361,194/yr | $15,900/yr |
How these numbers are built: annual use = 5.3 kWh/ft² (EIA CBECS 2018 Table C22, nonrefrigerated warehouse (mean; median 3.4)). 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 warehouse's bill
Lighting is the largest identified end use in EIA’s warehouse category (about 24%), followed by cooling (16%). Battery chargers for forklifts, conveyors and dock equipment make up much of the rest.
The median warehouse operates 50 hours a week, but multi-shift distribution centers run 100+ hours. Forklift charging after shifts can create a demand spike if every charger starts at once.
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 warehouse
Large distribution centers are mercantile customers and often buy through RFPs with block-and-index or fixed products; smaller warehouses buy standard small-commercial offers.
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 warehouse can cut costs
- Upgrade high-bay lighting to LED with occupancy sensors in aisles.
- Stagger forklift battery charging (or use opportunity charging) so chargers do not all start at shift change.
- Add high-volume low-speed fans instead of cooling large volumes of air.
- Plan for electrified fleets now — EV truck charging can double a site’s peak.
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 warehouse in this market, the useful starting evidence is forklift charging and dispatch peaks separately from low-occupancy periods. 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 warehouse review should test these operating questions
- Load separation: identify lighting, material handling and battery charging. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document a second shift, new automation or a change in loading hours. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
- Comparable performance: track kWh per throughput unit with shifts and floor area alongside it. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Do chargers start together after the same shift? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Will new material-handling equipment change the demand class? 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 warehouse | 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 second shift, new automation or a change in loading hours | 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 warehouses and distribution centers, preserve kWh per throughput unit with shifts and floor area 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.
