Columbus Retail Store Electricity Costs: AEP Ohio Guide
Retail Stores · Columbus, Ohio
What does electricity cost a retail store in Columbus?
A mid-size retail store (10,000 ft²) uses roughly 137,000 kWh a year. CBECS 2018 puts retail buildings (other than malls) at about 13.7 kWh per square foot per year (median 9.0). 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 |
|---|---|---|---|---|---|
| 3,000 ft² | 41,100 kWh | 10 kW | 9 kW | $1,065/yr (≈2.6¢/kWh) | $206/yr |
| 10,000 ft² | 137,000 kWh | 35 kW | 30 kW | $3,549/yr (≈2.6¢/kWh) | $685/yr |
| 40,000 ft² | 548,000 kWh | 139 kW | 118 kW | $14,197/yr (≈2.6¢/kWh) | $2,740/yr |
How these numbers are built: annual use = 13.7 kWh/ft² (EIA CBECS 2018 Table C14, retail (other than mall) (mean; median 9.0)). Peak demand assumes a 45% 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 Columbus retail store's bill
Lighting and ventilation are about 25% each of retail electricity in CBECS, followed by cooling (13%) and refrigeration (7%).
Median retail operating hours are 55 a week, with peaks on summer afternoons and holiday-season evenings when lighting, HVAC and door traffic coincide.
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 retail store
Single stores are small-commercial accounts; chains typically buy all Ohio locations together with one supplier and a master agreement, splitting price by utility territory.
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 retail store can cut costs
- Convert sales-floor and sign lighting to LED on astronomical time clocks.
- Keep entry vestibules and door closers working; open doors drive HVAC load.
- Set rooftop-unit schedules to store hours and lock thermostats.
- For chains, standardize settings and compare every store’s kWh per square foot.
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 retail store in Columbus?
A 10,000 ft² retail store uses roughly 137,000 kWh a year; multiply by the generation price on your AEP Ohio bill, then add delivery, demand charges and taxes.
Which utility serves retail 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 retail store use?
At CBECS’s 13.7 kWh/ft², a 10,000 ft² store would use roughly 137,000 kWh a year.
Can a chain buy electricity for all its Ohio stores at once?
Yes — a portfolio contract is common; prices are usually set per utility territory.

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 retail store in this market, the useful starting evidence is sales-floor hours separately from stockroom and security 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 retail store review should test these operating questions
- Load separation: identify store lighting, rooftop cooling and trading schedules. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document a store relocation, fit-out, closure or longer trading day. 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, with sales-floor area shown. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Are exterior signs and common areas on the tenant meter? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Can the contract handle a lease expiry before the supply end date? 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 retail 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 a store relocation, fit-out, closure or longer trading day | 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 retail stores, preserve kWh per open hour, with sales-floor area shown 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.
