Can several data centers in Franklin County share one electricity contract?
Yes, with one caveat: Franklin County is served by two investor-owned utilities (AEP Ohio and Ohio Edison), and suppliers price each utility territory separately. A single master agreement can still cover every site, with a price column per utility.
Leave out any location served by a municipal electric system — in Franklin County that includes Columbus (Division of Power), Obetz, and Westerville — because those meters generally can't be enrolled with a retail supplier.
Rural sites served by an electric cooperative — Consolidated Cooperative, South Central Power Company, and The Energy Cooperative (Licking Rural Electrification) — are in the same position.
Portfolio math for data centers in Franklin County
Take an illustrative operator with three smaller and two mid-size locations (250 kW IT load and 1,000 kW IT load):
| Portfolio measure | Estimate |
|---|---|
| Combined annual use | 37.10 million kWh |
| Combined capacity tags | about 4,470 kW |
| Capacity cost at 2026/27 price ($329.17/MW-day) | about $537,091 a year |
| Illustrative tags at the 2024/25 RTO reference ($28.92/MW-day) | about $47,187 a year |
| Value of each 0.5¢/kWh in supply price | about $185,493 a year |
How these numbers are built: annual use = IT load × PUE 1.54 (Uptime Institute 2025 average) × 8,760 hours. Peak demand assumes a 90% load factor; the capacity tag assumes 95% 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.
At that combined size the operator is a meaningful account for suppliers, even if each location on its own is below Ohio's 700,000 kWh-a-year “mercantile” line. Each account's aggregation eligibility is still judged site by site.
Utilities and default prices across Franklin County
| Utility | Small-business default generation price | Cities on this site in the county |
|---|---|---|
| AEP Ohio | Varies by rate schedule (on your bill) | Columbus, Dublin, Gahanna, Grove City, Hilliard, Reynoldsburg, Upper Arlington |
| Ohio Edison | Historical class reference: 9.38¢/kWh (June 1, 2026 – May 31, 2027, annual average) | — |
| Westerville Electric Division | Not shoppable (municipal) | Westerville |
Structuring a multi-site contract
- Master agreement with site schedules. Sign one agreement and list each location on a schedule, so opening or closing a data center is an amendment, not a new negotiation.
- Add/delete rights. Ask for the right to add new locations at the contract price (or a formula) and to remove closed locations without penalty up to a set share of volume.
- Aggregate bandwidth. Measure usage tolerance across the whole portfolio rather than meter by meter, so one busy site doesn't trigger true-up charges.
- Co-terminous end dates. Put every site on the same end date so the next bid covers the full portfolio.
- Aggregation exits. Locations at 700,000 kWh a year or less may be in a community aggregation program; confirm how each will be moved to the new supplier and whether any exit terms apply.
Operating issues specific to data centers
IT load runs 24/7/365, so load factor is very high (often above 85%). Summer peaks come from cooling, which is why PUE rises in hot months.
Across a portfolio, the biggest wins usually come from standardizing settings and comparing sites against each other. For data centers, that means:
- Raise supply-air temperatures within ASHRAE recommended ranges and contain hot/cold aisles.
- Use economizer hours — Ohio winters allow significant free cooling.
- Retire or consolidate lightly used servers before buying more power.
AEP Ohio’s data-center tariff (approved July 2025) applies to new data-center load over 25 MW and requires paying for at least 85% of contracted capacity for up to 12 years; smaller enterprise server rooms are not covered by it.
FAQ
Can a data center operator buy electricity for all Franklin County locations together?
Yes. A supplier can put every shoppable site under one agreement; expect separate prices for AEP Ohio and Ohio Edison accounts.
Which Franklin County locations can't be included?
Sites served by municipal systems in Columbus (Division of Power), Obetz, and Westerville or electric cooperatives (Consolidated Cooperative, South Central Power Company, and The Energy Cooperative (Licking Rural Electrification)) generally can't be enrolled with a retail supplier.
What PUE should an Ohio data center target?
Uptime’s 2025 survey average is 1.54; newer facilities average about 1.48. Ohio’s climate supports economizer cooling for much of the year.

Keep ownership and eligibility separate
A county-wide project can combine owner-operated locations, leased space and municipal-service accounts. Build the service schedule from each meter’s actual delivery utility and legal customer; a common county address is not a common enrollment right.
For a data center in this market, the useful starting evidence is IT consumption separately from supporting mechanical and electrical systems. 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 Franklin County | Evidence needed before pricing |
|---|---|
| AEP Ohio | Confirm the actual account class and contract; service territory is not the same as a county boundary. |
| Ohio Edison | Confirm the actual account class and contract; service territory is not the same as a county boundary. |
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 data center review should test these operating questions
- Load separation: identify IT load, cooling, UPS systems and standby equipment. Distinguish electricity use from gas, water and other operating costs before comparing a retail electric offer.
- Change case: document new rack capacity, server deployment or a cooling-system upgrade. Ask the supplier whether that change affects quoted volume, capacity treatment, demand assumptions or the offer’s validity.
- Comparable performance: track IT load and total facility load over the same measurement period. A raw dollar-per-month comparison mixes prices and operations; a unit measure needs the operating context beside it.
- Account responsibility: Are redundant supplies separately metered and contracted? Record the responsible party and who can authorize a contract before asking someone to sign.
- Contract fit: Does the delivery tariff or connection agreement impose special obligations? 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 data center | 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 rack capacity, server deployment or a cooling-system upgrade | 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 data centers, preserve IT load and total facility load over the same measurement period 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 Franklin County, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.
