What does electricity cost a grocery store in Cincinnati?

A mid-size grocery store (30,000 ft²) uses roughly 1.69 million kWh a year. CBECS 2018 puts grocery stores and food markets at about 56.4 kWh per square foot per year, one of the most electricity-intensive building types. The average grocery building uses about 1 million kWh a year. 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
12,000 ft²	677,000 kWh	110 kW	99 kW	$11,935/yr (≈1.8¢/kWh)	$76,873/yr	$3,384/yr
30,000 ft²	1.69 million kWh	276 kW	248 kW	$29,837/yr (≈1.8¢/kWh)	$192,182/yr	$8,460/yr
50,000 ft²	2.82 million kWh	460 kW	414 kW	$49,728/yr (≈1.8¢/kWh)	$320,304/yr	$14,100/yr

How these numbers are built: annual use = 56.4 kWh/ft² (EIA CBECS 2018 Table C22, grocery store or food market (mean; median 43.5)). Peak demand assumes a 70% load factor; the capacity tag assumes 90% 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 grocery store's bill

Refrigeration is about 48% of food-sales electricity in CBECS — display cases, walk-ins and compressor racks. Lighting and ventilation are around 7% each.

Median operating hours are 98 a week, but refrigeration makes the load nearly flat around the clock. That high load factor means a large share of the bill is energy (kWh) rather than demand, and summer afternoons push compressor head pressure and peak kW up together.

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 grocery store

Flat, predictable load is exactly what suppliers like to price, so grocery accounts usually get competitive fixed quotes. Many single stores sit near or above the 700,000 kWh/yr mercantile line, which changes aggregation eligibility and gives access to behind-the-meter options under HB 15.

Practical steps for a single location:

1. Pull 12 months of Duke Energy Ohio bills and note the rate schedule, peak kW and any supplier already listed.
2. 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.
3. Ask for fixed prices that include capacity for 12, 24 and 36 months and compare each against the default price on your actual usage.
4. Make sure every quote shows broker compensation and any pass-through charges as separate lines.

Where a Cincinnati grocery store can cut costs

• Add doors to open multi-deck cases and night covers where doors are not practical.
• Tune floating head pressure and suction controls on compressor racks, and keep condensers clean before summer.
• Convert case lighting and sales-floor lighting to LED with occupancy-based dimming in back rooms.
• Review anti-sweat heater controls on case doors; many run continuously when they only need to run in humid weather.

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 grocery store in this market, the useful starting evidence is compressor behavior through hot afternoons and the closed-store load. 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.

Delivery-utility guide for Cincinnati	Evidence needed before pricing

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 grocery store review should test these operating questions

• Load separation: identify compressor racks, display cases and overnight refrigeration. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
• Change case: document new refrigerated cases, a remodel or an extended opening schedule. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
• Comparable performance: track kWh per open hour and conditioned floor area, without ignoring refrigeration. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
• Account responsibility: Are defrost and anti-sweat controls maintaining safe temperatures? Record the responsible party and who can authorize a contract before asking someone to sign.
• Contract fit: Does a refrigeration failure change usage enough to trigger a bandwidth clause? Ask for the answer in the actual agreement or written offer schedule, rather than relying on a sales summary.

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 grocery stores, preserve kWh per open hour and conditioned floor area, without ignoring refrigeration 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.
