Columbus Office Building Electricity Costs: AEP Ohio Guide
Office Buildings · Columbus, Ohio
What does electricity cost a office building in Columbus?
A mid-size office building (50,000 ft²) uses roughly 680,000 kWh a year. CBECS 2018 puts offices at about 13.6 kWh per square foot per year (median 10.1); the average office building uses about 234,000 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 |
|---|---|---|---|---|---|
| 10,000 ft² | 136,000 kWh | 35 kW | 29 kW | $3,523/yr (≈2.6¢/kWh) | $680/yr |
| 50,000 ft² | 680,000 kWh | 173 kW | 147 kW | $17,617/yr (≈2.6¢/kWh) | $3,400/yr |
| 150,000 ft² | 2.04 million kWh | 518 kW | 440 kW | $52,850/yr (≈2.6¢/kWh) | $10,200/yr |
How these numbers are built: annual use = 13.6 kWh/ft² (EIA CBECS 2018 Table C14, office (mean; median 10.1)). 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 office building's bill
Ventilation is the largest office electric end use in CBECS (about 28%), then lighting (17%), computing (11%) and cooling (10%).
Median office operating hours are 45 a week: a weekday daytime profile that peaks on summer afternoons. Buildings with partial post-pandemic occupancy often still run HVAC as if they were full.
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 office building
Single-tenant offices usually buy standard fixed products; multi-tenant landlords buy base-building (common area and central HVAC) power and may resell or allocate it to tenants under the lease.
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 office building can cut costs
- Re-set HVAC schedules and ventilation rates to actual occupancy (badge data is a good source).
- Retro-commission the building automation system: fix simultaneous heating/cooling and overridden schedules.
- Upgrade to LED with occupancy and daylight controls.
- Tie server-room cooling to its own efficient unit instead of running the whole building overnight.
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 office building in Columbus?
A 50,000 ft² office building uses roughly 680,000 kWh a year; multiply by the generation price on your AEP Ohio bill, then add delivery, demand charges and taxes.
Which utility serves office buildings 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 an office building use?
CBECS 2018 reports about 13.6 kWh per square foot per year on average, so a 50,000 ft² office would use roughly 680,000 kWh.
What is the biggest electric load in an office?
Ventilation fans (about 28% of office electricity in CBECS), followed by lighting.

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 office building in this market, the useful starting evidence is occupied-hours demand separately from overnight building operation. 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 office building review should test these operating questions
- Load separation: identify HVAC, lighting, plug loads and tenant schedules. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document hybrid-work changes, tenant fit-outs or leased-space vacancy. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
- Comparable performance: track kWh per occupied square foot and operating hour. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Who controls after-hours HVAC overrides? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Does the landlord or each tenant sign for its own meter? 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 office building | 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 hybrid-work changes, tenant fit-outs or leased-space vacancy | 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 office buildings, preserve kWh per occupied square foot and operating hour 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.
