Columbus Apartment Building Electricity Costs (AEP Ohio)
Apartment Buildings · Columbus, Ohio
What does electricity cost a apartment building in Columbus?
A mid-size apartment building (100 units, master-metered) uses roughly 609,000 kWh a year. EIA’s Residential Energy Consumption Survey (2020) reports about 6,093 kWh a year per household in buildings with five or more units. Owners typically pay for common areas, and for the whole building where units are master-metered. 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 |
|---|---|---|---|---|---|
| 24 units, master-metered | 146,000 kWh | 33 kW | 27 kW | $3,209/yr (≈2.2¢/kWh) | $731/yr |
| 100 units, master-metered | 609,000 kWh | 139 kW | 111 kW | $13,371/yr (≈2.2¢/kWh) | $3,046/yr |
| 300 units, master-metered | 1.83 million kWh | 417 kW | 334 kW | $40,113/yr (≈2.2¢/kWh) | $9,140/yr |
How these numbers are built: annual use = EIA RECS 2020: 6,093 kWh per household in 5+ unit buildings. Peak demand assumes a 50% 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 Columbus apartment building's bill
Owner-paid loads include hallway and parking lighting, elevators, central HVAC and hot water, laundry rooms and amenity spaces; in master-metered buildings, tenant use becomes the owner’s cost too.
EIA data show residential summer load rising through the day to a peak around 5–6 p.m., with winter morning and evening peaks — so master-metered buildings follow household patterns.
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 apartment building
House (common-area) meters are commercial accounts the owner can shop. Portfolio owners typically bid all house meters together; tenant-metered units are shopped by each tenant.
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 apartment building can cut costs
- Convert corridor, stairwell and parking lighting (24/7 loads) to LED with occupancy controls.
- Put common-area HVAC and amenity spaces on schedules.
- Consider submetering master-metered buildings where Ohio rules and leases allow.
- Maintain central boilers, pumps and hot-water systems.
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 apartment building in Columbus?
A 100 units, master-metered apartment building uses roughly 609,000 kWh a year; multiply by the generation price on your AEP Ohio bill, then add delivery, demand charges and taxes.
Which utility serves apartment owners 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.
Who buys electricity in an apartment building?
The owner buys for common areas and master-metered units; tenants on their own meters buy their own.
How much electricity does an apartment use?
EIA’s 2020 survey reports about 6,093 kWh a year per unit in buildings with five or more apartments.

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 apartment building in this market, the useful starting evidence is owner-paid loads separately from individually billed apartments. 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 apartment building review should test these operating questions
- Load separation: identify common-area systems, central services and resident metering. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document a boiler-to-heat-pump project, EV charging or occupancy changes. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
- Comparable performance: track common-area kWh per occupied unit, not a mix of tenant and owner bills. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Which costs legally belong to the landlord’s accounts? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Does a property sale permit assignment of the supply agreement? 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 apartment 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 a boiler-to-heat-pump project, EV charging or occupancy changes | 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 apartment owners, preserve common-area kWh per occupied unit, not a mix of tenant and owner bills 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 Columbus, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.
