What does electricity cost a data center in Cleveland?
A mid-size data center (1,000 kW IT load) uses roughly 13.50 million kWh a year. Data centers are measured by IT load and power usage effectiveness (PUE), not square feet. The Uptime Institute’s 2025 survey reports an average PUE of 1.54 and a typical rack density near 9 kW. In Cleveland, that power is delivered by The Illuminating Company, and the generation portion can be bought from a PUCO-certified supplier.
On The Illuminating Company's default price for small businesses — about 9.45¢/kWh on the GS rate (June 1, 2026 – May 31, 2027, annual average) — the generation cost alone for the sites below looks like this:
| Illustrative site | Annual use | Est. peak demand | Est. capacity tag | Capacity cost at 2026/27 price | Generation cost at 9.45¢/kWh | Value of 0.5¢/kWh |
|---|---|---|---|---|---|---|
| 250 kW IT load | 3.37 million kWh | 428 kW | 406 kW | $48,826/yr (≈1.4¢/kWh) | $318,721/yr | $16,863/yr |
| 1,000 kW IT load | 13.50 million kWh | 1,711 kW | 1,626 kW | $195,306/yr (≈1.4¢/kWh) | $1.27 million/yr | $67,452/yr |
| 5,000 kW IT load | 67.50 million kWh | 8,556 kW | 8,128 kW | $976,529/yr (≈1.4¢/kWh) | $6.37 million/yr | $337,260/yr |
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.
What drives a Cleveland data center's bill
At a PUE of 1.54, about 35% of the facility’s energy goes to cooling and power conversion and about 65% reaches IT equipment.
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.
On a The Illuminating Company 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. The Illuminating Company (CEI) bill shows a "Price to Compare" on the generation section. For businesses on the GS rate, CEI's default generation price averaged about 9.45¢/kWh for June 2026–May 2027.
Cleveland specifics
Because Cleveland Public Power and CEI serve the city block by block, a multi-site owner needs to sort Cleveland meters by utility before asking for prices — suppliers can only enroll the CEI accounts.
For CEI accounts on the GS rate, the default generation price averaged about 9.45¢/kWh for June 2026–May 2027 — the highest of the three FirstEnergy utilities.
Buying electricity for one Cleveland data center
Enterprise and colocation data centers buy through RFPs, often on block-and-index or fully indexed products with hedges, and increasingly add renewable energy certificates or PPAs to meet customer requirements.
Practical steps for a single location:
- Pull 12 months of The Illuminating Company 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 Cleveland data center can cut costs
- 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.
- Plan generator and UPS strategy around PJM emergency events and demand response.
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 data center in Cleveland?
At The Illuminating Company's small-business default generation price of about 9.45¢/kWh, a 1,000 kW IT load data center using 13.50 million kWh a year would pay about $1.27 million a year for generation alone, before delivery, demand charges and taxes.
Which utility serves data centers in Cleveland?
The Illuminating Company. Cleveland Public Power (CPP), the city-owned utility, serves roughly 74,000 homes and businesses in parts of Cleveland block by block; CPP accounts cannot choose a competitive supplier. The Illuminating Company serves the rest of the city.
How much electricity does a small data center use?
A 250 kW IT load at a PUE of 1.54 uses about 3.4 million kWh a year (250 × 1.54 × 8,760 hours).
Does AEP Ohio’s data-center tariff apply to my server room?
Only to new data-center loads over 25 MW in AEP Ohio territory; ordinary enterprise server rooms are billed on standard tariffs.

A mixed-utility city needs meter-level proof
Cleveland includes The Illuminating Company and Cleveland Public Power service. Establish the actual utility before obtaining supply bids. Do not place a city-system meter in the same competitive-supplier enrollment schedule as a CEI meter.
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.

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 Cuyahoga County
Use a separate row for every property rather than one total for the whole business. Start with Cleveland, Cleveland Heights, Euclid, Garfield Heights, Lakewood, Maple Heights, North Olmsted, North Royalton. 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 Cleveland, and describe the question without account numbers or attachments. A supplier bid follows only if the account and decision support that step.
