Why Your Electric Bill Keeps Climbing, and What Data Centers Have to Do With It

Ken Apacki has kept a spreadsheet of every charge on his electric bill for the past five years. The retired couple in Granville, Ohio, watched their rate climb from 11 to 12 cents a kilowatt-hour in 2020 to 19 cents by 2025 — a jump of about 60% — and they have a theory about why. "A hundred and thirty data centers in Central Ohio," Carol Apacki told NPR's Planet Money. "I mean, that is amazing."

If your own bill has crept up this summer and you've wondered whether the AI boom is quietly on your tab, the short answer is: partly, yes — but not in the way the headlines suggest. The mechanism is worth understanding, because it explains both why the increase is real and why switching off your own air conditioner won't fix it.

Start with what an electric bill actually is. It has three moving parts. Distribution is the local wires that carry power the last mile to your house. Transmission is the high-voltage network that hauls electricity across regions. Generation is the power plants that make the electricity in the first place. Data centers push on all three, and here is the catch that turns their appetite into your problem: under the way most grids are billed, the cost of expanding the system is spread across everyone connected to it.

Do data centers actually raise your electricity bill?

They can, and increasingly they do — mostly through that third bucket, generation. Marc Reitter, who runs the Apackis' utility, AEP Ohio, put the billing logic plainly: "everybody pays fair share. That's the crux of the model." A grid built as shared infrastructure means a surge of demand from a few enormous customers ripples out to the many.

Cathy Kunkel, an analyst at the Institute for Energy Economics and Financial Analysis, described where that leads.

"I think it's almost inevitable, the way that these structures are set up, that ordinary people are going to end up subsidizing the wealthiest industry in the world."

The demand side is not subtle. U.S. data centers' total combined power draw is projected to nearly double between 2025 and 2028, from 80 to 150 gigawatts, according to a January 2026 analysis cited by the Environmental and Energy Study Institute. To serve that, utilities are building substations, transmission lines and new plants — and the bill for that construction filters down to residential customers whether or not a single one of them ever queries a chatbot.

Why is my electric bill so high all of a sudden?

Two things are colliding at once. The slow burn is the data-center build-out. The fast one is heat. When a heat dome parks over the eastern half of the country and everyone runs air conditioning at the same hour, wholesale power prices spike to meet that peak — and in regions dense with data centers, the baseline those spikes build on is already elevated. That's why the sticker shock tends to land in July, not January.

Residential electricity prices rose about 25% nationally between 2020 and 2024, and kept climbing through 2025 at a pace well above general inflation. The increases are not evenly spread. In the mid-Atlantic grid known as PJM — a 13-state territory stretching from Illinois to Washington, D.C., and a magnet for data-center construction — analysts have estimated the capacity crunch could add 10% to 20% to a typical household's bill. Daybreak Wire covered the acute version of that strain when PJM ordered emergency power cuts during a record heat stretch, and again when the Energy Department pulled data centers onto backup power to keep the grid standing.

A caution on the scariest number you'll see. Reporting that electricity "costs 267% more" near data centers in Virginia refers to wholesale prices — what generators charge into the market — not the retail bill that lands in a mailbox. Fact-checkers have flagged the gap between the wholesale figure and household experience. The retail increases are large enough without inflating them.

Which states are getting hit hardest?

Geography tracks the server farms. Ohio, Virginia and the broader PJM footprint — the places where cheap land, tax incentives and fiber pulled the hyperscalers — are where residential bills have moved most. Virginia's "Data Center Alley" in Loudoun County is the extreme case; Central Ohio, with the cluster the Apackis can practically see from their porch, is close behind. If you live far from a data-center corridor, your increase is more likely driven by ordinary culprits: fuel costs, storm-hardening of the grid, and the same summer peak everyone faces.

What can actually lower your bill?

Less than you'd like, and that's the uncomfortable part. Because most of the increase sits in generation and transmission — costs set by the market and the grid, not by your thermostat — personal conservation nibbles at the edges. The lever that matters is regulatory: whether state utility commissions force data centers to pay for the infrastructure they specifically require, rather than socializing it across every ratepayer. AEP Ohio has already written new rules trying to make data centers shoulder more of the expansion they trigger, and other states are weighing the same. Kunkel's fix is blunter — reform the rules "so that more of the costs of expanding electricity infrastructure are paid by the data centers themselves."

Until those fights are settled, the household playbook is the familiar one: check whether your utility offers a time-of-use rate that rewards shifting laundry and dishwashing off the late-afternoon peak, ask about budget billing to smooth the summer spikes, and treat efficiency upgrades as the only cost you fully control. None of it undoes the structural shift. The wealthiest industry in the world is building its future on a grid you help pay for, and the meter on the side of the house keeps a quieter spreadsheet than Ken Apacki's — but it's recording the same story.
