Columbus Grocery Store Electricity Costs: AEP Ohio Guide
Grocery Stores · Columbus, Ohio
What does electricity cost a grocery store in Columbus?
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 Columbus, that power is delivered by AEP Ohio, and the generation portion can be bought from a PUCO-certified supplier.
AEP Ohio prints your business price to compare on the bill (it varies by rate schedule), so the table below shows usage, demand and capacity — the pieces a supplier will price:
| Illustrative site | Annual use | Est. peak demand | Est. capacity tag | Capacity cost at 2026/27 price | Value of 0.5¢/kWh |
|---|---|---|---|---|---|
| 12,000 ft² | 677,000 kWh | 110 kW | 99 kW | $11,935/yr (≈1.8¢/kWh) | $3,384/yr |
| 30,000 ft² | 1.69 million kWh | 276 kW | 248 kW | $29,837/yr (≈1.8¢/kWh) | $8,460/yr |
| 50,000 ft² | 2.82 million kWh | 460 kW | 414 kW | $49,728/yr (≈1.8¢/kWh) | $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 Columbus 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 an AEP 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. AEP Ohio (operating as Ohio Power Company from October 1, 2026) is moving to a redesigned bill that separates distribution, transmission and generation, which makes the shoppable generation line easier to find.
Columbus specifics
Central Ohio is where Ohio's electric demand is growing fastest. Large data-center campuses around New Albany, Hilliard and Dublin led AEP Ohio to adopt its 2025 data-center tariff, which requires new data-center loads over 25 MW to pay for at least 85% of the capacity they reserve. The tariff doesn't apply to ordinary businesses, but grid build-out for that growth flows into transmission charges everyone pays.
Buying electricity for one Columbus 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:
- Pull 12 months of AEP 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 Columbus 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.
FAQ
How much does electricity cost for a grocery store in Columbus?
A 30,000 ft² grocery store uses roughly 1.69 million kWh a year; multiply by the generation price on your AEP Ohio bill, then add delivery, demand charges and taxes.
Which utility serves grocery stores in Columbus?
AEP Ohio. The City of Columbus Division of Power serves about 12,500 meters (homes and businesses) in defined areas; those accounts cannot choose a competitive supplier. AEP Ohio serves the large majority of the city.
How much electricity does a grocery store use?
CBECS 2018 reports an average of about 1 million kWh a year per grocery building and 56.4 kWh per square foot. A 30,000 ft² store would be around 1.7 million kWh a year at that intensity.
What is the biggest electric load in a supermarket?
Refrigeration — about 48% of electricity in EIA’s food-sales category.

Growth plans and the right delivery company
Confirm whether the bill is for AEP Ohio or Columbus municipal service. An expansion or new building may be on a different service arrangement from the current location. Separate the existing contract decision from a new service connection or capacity request.
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.

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.
Evidence table for the next decision
| Question for this grocery store | 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 new refrigerated cases, a remodel or an extended opening schedule | 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 Franklin County
Use a separate row for every property rather than one total for the whole business. Start with Columbus, Dublin, Gahanna, Grove City, Hilliard, Reynoldsburg, Upper Arlington, Westerville. 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.
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 Columbus, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.
