Why Are Electricity Rates Rising in Ohio in 2026?

If your Ohio electric bill has felt noticeably heavier in 2026, you're not imagining it. Electricity rates are rising in Ohio, and prices have climbed across the state.

Ohio's average residential electricity price reached about 19.19¢ per kilowatt-hour in June 2026, up from about 17.50¢ in June 2025. (A kilowatt-hour, or kWh, is the unit of electricity on your bill.) That's an increase of nearly 10% in a single year.

So why is it happening? There isn't one cause. Ohio homeowners are feeling several things at once: higher wholesale power costs, much higher regional capacity prices, growing demand, transmission and grid investment, and one of the fastest data-center buildouts in the country.

Here's what's going on, and what you can actually do about it.

How Much Have Ohio Electricity Rates Increased?

Ohio has long had relatively affordable electricity compared with much of the country, but that gap has been closing.

Take a household using 1,000 kWh a month. The jump from about 17.50¢ to 19.19¢ per kWh works out to roughly $17 more per month, or about $200 more per year. That's before any change in how much electricity the home uses.

Your own number will depend on where you live, your utility, whether you shop for your electricity supply and how much power your home uses. But the statewide trend is clear: electricity has gotten meaningfully more expensive in Ohio.

1. PJM Capacity Costs Have Jumped

One of the biggest forces behind Ohio electricity costs isn't happening at your local utility at all. It's happening in the regional power market.

Ohio is part of PJM Interconnection, the grid operator that coordinates electricity across all or part of 13 states plus Washington, D.C. PJM runs a capacity market. In a capacity market, power plants get paid for promising to be available when the grid needs them most. That's on top of what they earn for the electricity they make today.

Those costs have climbed sharply. For the 2026–2027 delivery year, PJM's capacity price hit about $329.17 per megawatt-day. That cost works its way into what it takes to supply power to homes and businesses.

Why so high? Because demand is growing faster than new generation is being added. And PJM has pointed to one especially important source of that demand: data centers.

2. Ohio's Data Center Boom Is Creating Huge New Demand

Ohio, and Central Ohio in particular, has become one of America's major data-center markets. The draws include available land, fiber infrastructure, a business-friendly climate and access to the regional grid. Modern data centers use an extraordinary amount of power.

In February 2026, AEP Ohio reported binding contracts for about 5,642 megawatts of new data-center demand under its new Data Center Tariff. That's on top of roughly 12,219 megawatts signed before the tariff took effect. Combined, that's nearly 17,900 megawatts of contracted data-center demand. That's not a few office buildings. It's an industrial-scale change in how much electricity the region needs.

PJM has said data centers are now the main driver of demand growth in its territory. It has also said they can be built two to three times faster than many of the power plants needed to serve them. When demand shows up faster than supply, prices tend to rise.

Are Ohio Homeowners Paying for Data Centers?

This one deserves some nuance. The answer isn't simply “homeowners are paying data centers' electric bills.” Ohio regulators have actively tried to prevent that.

In 2025, the Public Utilities Commission of Ohio (PUCO) approved AEP Ohio's Data Center Tariff. It requires large data centers to make major long-term financial commitments before the utility builds infrastructure for them. That protects ordinary customers from being stuck with the cost of facilities that are announced but never built. That's good policy.

But it doesn't erase the bigger market effect. Even when a data center pays for its own connection, thousands of megawatts of new demand still ripple through the system. They affect regional supply, generation needs, capacity prices, transmission planning, congestion and future investment.

3. Ohio Needs More Power Generation

That's the other half of the equation. Demand is growing, but new generation takes time to build, and some older plants have retired or are scheduled to.

Imagine a city adding thousands of new homes while building almost no new roads. Eventually you get traffic. Ohio and the wider PJM market are facing something similar. More customers, especially massive industrial loads, are competing for power on a grid where new generation has struggled to keep up.

4. Transmission Costs Are Rising

Making electricity is only part of the cost. It also has to travel over high-voltage transmission lines before it reaches your local system. Those lines need new substations, bigger conductors, transformer upgrades, modernization, reliability work and maintenance. Those costs are recovered through rates.

AEP Ohio is a good example. In April 2026, transmission costs for an average residential customer using 1,000 kWh rose by about $7.90 a month. Generation costs fell at the same time, so the overall impact of that particular update was only about 22 cents. But it shows that your bill isn't just about the price of generating power. Transmission and distribution matter too.

5. Ohio Utilities Are Investing Heavily in the Grid

Ohio's grid wasn't built for the amount or type of demand now being forecast. Utilities are replacing aging equipment while preparing for growth: power lines, substations, transformers, smart-grid technology, storm hardening, tree trimming, distribution equipment and transmission capacity.

Those investments can improve reliability, but they aren't free. Approved utility investments are recovered from customers through regulated rates. That makes grid modernization another long-term source of upward pressure.

6. Supply Prices Have Gone Up, Too

Ohio is an electric-choice state, so many homeowners can buy their electricity supply from a competitive supplier instead of their utility's default service. For customers who stay on default service, the price is generally set through competitive wholesale auctions. Those results can swing a lot from year to year.

FirstEnergy's three Ohio utilities are a good example. Starting June 1, 2025, their residential Prices to Compare (the utility's default supply price) rose to about:

• Ohio Edison — 9.35¢/kWh
• The Illuminating Company — 9.11¢/kWh
• Toledo Edison — 9.52¢/kWh

That was up from the low-7-cent range the year before. By summer 2026, Ohio Edison's Price to Compare had reached about 10.92¢/kWh. FirstEnergy pointed largely to tighter supply and rising regional demand.

The takeaway: your bill can change even when your utility's distribution rate hasn't. Sometimes the electricity itself simply costs more.

7. Weather Can Make Higher Rates Hurt Even More

Price and usage are separate issues. Your bill can go up because the cost per kWh went up, because the home used more kWh, or both at the same time.

Hot Ohio summers push air-conditioning use. Cold winters push heating use, especially in homes with heat pumps or electric resistance heat. Combine higher rates with heavy usage and you get a much bigger bill.

That's why you should look at the kilowatt-hours on your bill, not just the dollar amount.

If your usage looks similar to last year but the bill is much higher, pricing is likely the bigger factor. If both went up, you're dealing with both problems at once.

Will Ohio Electricity Rates Keep Rising?

Nobody can predict electricity prices perfectly. Rates move with fuel prices, weather, wholesale markets, regulatory decisions, power-plant additions and retirements, transmission costs and demand.

But Ohio's long-term picture is changing. PJM is openly warning that demand is growing fast and data-center development remains aggressive. It also points out that utilities are expanding the grid and a lot of new generation will be needed. That doesn't guarantee a big increase every year. It does mean homeowners shouldn't assume electricity will stay cheap just because Ohio power used to be affordable.

What Can Ohio Homeowners Do About Rising Costs?

You can't control PJM, utility infrastructure spending or how many data centers get built. You can control how efficiently your home uses electricity and how much of it you buy from the grid.

1. Check your electricity supplier. Because Ohio has electric choice, it's worth reviewing the generation rate on your bill now and then. Compare your supplier's rate with your utility's Price to Compare, and don't stop at the advertised rate. Check the contract length, fixed versus variable pricing, early termination fees, introductory rates, monthly fees and automatic renewal terms. A slightly lower rate isn't a better deal if the contract terms are bad.

2. Evaluate your HVAC system. Heating and cooling are often a home's biggest energy expense, and an inefficient system can use far more electricity than it needs to. If your equipment is aging, look at its efficiency, condition, duct leakage, sizing, airflow and the insulation around it. Sometimes the best energy investment isn't solar — it's cutting what the home wastes first.

3. Improve insulation and air sealing. A well-insulated home needs less energy to stay comfortable. Attics, exterior doors, windows and ductwork can all have a big effect on heating and cooling costs. And using less electricity saves money no matter what rates do.

4. Consider solar. Solar lets you generate part of your own electricity instead of buying every kilowatt-hour from the utility. That can reduce your exposure to future rate increases. The economics depend on roof direction, shade, usage, system size, financing, utility rules and available incentives. It isn't right for every home, but as grid power gets more expensive, the math on making your own can change.

5. Consider battery storage. A battery lets you keep solar power and use it later, and depending on the setup, it can also provide backup during outages. For homeowners thinking past today's bill, solar plus storage is a different strategy altogether: produce, store and manage more of your electricity at home.

Solar vs. Utility Power in Ohio: Think Long Term

One of the most common mistakes in evaluating solar is comparing a solar payment only to today's electric bill. A more useful comparison is:

• What will I spend buying electricity over the next 20–25 years?
• What would it cost to produce some of that electricity myself?

If rates keep rising, those two numbers can look very different. That's especially relevant in Ohio, because the forces pushing demand — data centers, electrification, grid modernization — aren't going away soon.

Ashborn's Whole-Home Energy Approach

We don't believe every homeowner needs the same solution. A home with a 20-year-old HVAC system may need an efficiency upgrade before anything else. Another home may already be efficient but use enough power to make solar attractive. Another may care most about battery backup and energy independence.

The goal shouldn't be to sell a homeowner one more energy product. It should be to answer a better question:

That might include HVAC, solar, battery storage, insulation, roofing or other efficiency upgrades. The right answer starts with understanding the home.

The Bottom Line

Ohio electricity rates are rising because several big forces are hitting at once:

• Growing demand
• Higher PJM capacity costs
• Unprecedented data-center loads
• A grid that has to expand
• New generation that's slow to catch up
• More expensive wholesale supply

The result: Ohio's average residential price in June 2026 was nearly 10% higher than a year earlier.

For homeowners, the real question isn't whether rates go up next month. It's how much electricity your home will buy from the grid over the next 10, 20 or 25 years — and what that will cost. The homeowners who understand that today will be in a much better position to control their energy costs tomorrow.
