Ohio · plain-English answer
Why is my Ohio electric bill so high?
You're not imagining it. The average Ohio residential electricity price rose 37% in 6 years — from 12.38¢/kWh in 2019 to 16.96¢/kWh in 2025. Here's what's behind it, and the one part you can actually fix.
That's not just inflation: in real (inflation-adjusted) terms, Ohio prices are still up about 9%. (Source: U.S. Bureau of Labor Statistics (CPI-U).)

If a third-party supplier is charging more than your utility's Standard Service Offer, you're overpaying — and you can switch back. Check it free, in your browser:
Check my rateHow much of your Ohio bill is the data-center surge?
Ohio is in the PJM grid, where capacity costs jumped largely because of data-center demand. PJM estimates this adds about 1.5%–5% to customer bills. Enter your monthly bill to see that as dollars:
How we calculated this
We take PJM's own published estimate that recent capacity-cost increases add about 1.5%–5% to customer bills, and apply that range to the bill amount you enter — entirely in your browser. It's an estimate, not a precise figure: your exact share depends on your utility and usage, and PJM attributes a large part (not all) of the capacity increase to data centers. Source: PJM Interconnection (as of 2025-07).
Why data centers are driving this:
PJM raised its 2031 peak-load forecast for the Dayton (AES Ohio) zone by about 27% (~1 GW), driven largely by data-center additions. — PJM 2025 Long-Term Load Forecast (2025-12).
Data centers account for about 94% of PJM's projected peak-load growth between 2024 and 2030 (roughly +32 GW). — PJM 2025 Long-Term Load Forecast (2025-12).
PJM's capacity-auction price hit a record cap (~$333/MW-day) for the third auction in a row, and its market monitor attributed roughly 40% of those costs to data centers. — PJM Independent Market Monitor (Monitoring Analytics); Utility Dive (2025-07).
US data centers used about 4.4% of all US electricity in 2023, up from 1.9% in 2018. — LBNL / US DOE — 2024 United States Data Center Energy Usage Report (2024-12).
Data centers are projected to reach 6.7%–12% of total US electricity by 2028. — LBNL / US DOE — 2024 United States Data Center Energy Usage Report (2024-12).
What is "PJM" and its "capacity market"? (plain English)
PJM is the independent operator that runs the high-voltage power grid for 13 states and Washington, D.C. — including yours. Think of it as air-traffic control for electricity: it doesn't own power plants or your wires, but it makes sure enough electricity is flowing across the whole region every second of the day. The wholesale costs PJM sets get passed through your utility into your bill.
The capacity market is a separate, once-a-year auction PJM runs. Instead of paying for electricity you use, it pays power plants just to promise they'll be ready on the few hottest or coldest days when demand peaks. That promise is called "capacity." It's like paying a backup generator a retainer to stay on standby — you pay even in months you never need it.
Why it matters now: when PJM expects demand to jump, those standby payments spike. Demand is jumping largely because of data centers, and PJM's recent capacity auctions hit record highs three times in a row. Utilities pass that cost straight to customers — which is a big reason bills across all five states we cover are rising. Sources: PJM; PJM Independent Market Monitor (Monitoring Analytics).

A supplier charging more than your utility
If you signed up with a competitive supplier, your rate may be well above your utility's Standard Service Offer — often after a teaser rate expired. This is the most common fixable cause. Run the free audit →
Common questions
- Why is my Ohio electric bill so high in 2025?
- Ohio residential electricity prices have risen 37% since 2019 — from about 12.38¢ to 16.96¢ per kWh. The biggest drivers are higher PJM grid costs (capacity prices hit record highs, largely from data-center demand), plus, if you're on a third-party supplier, a contract rate that may be well above your utility's standard rate.
- Why did my electricity rate seem to double?
- A bill that feels doubled is usually a third-party supplier rate, not your utility's. Teaser rates expire and can reset to two or three times the utility's standard rate. The other common cause is a usage spike (weather or a new appliance). A 30-second bill audit tells you instantly if the supply rate is the problem.
- What is the standard electricity rate in Ohio right now?
- Your utility's standard rate — the Standard Service Offer — is what you pay if you don't use a competitive supplier. For example, AEP Ohio's is 10.12¢/kWh as of June 14, 2026. If a supplier charges you more than your utility's Standard Service Offer, you're overpaying.
- What can I do about a high electric bill?
- Check whether a supplier is overcharging you versus your utility's Standard Service Offer — that's the part you can fix in 1–2 billing cycles, free. Our bill audit does the comparison in your browser; nothing leaves your device.
