The Power Behind the Boom: What the Data Center Buildout Is Really Doing to America’s Grid

By Michelle Carlberg

A few weeks ago I wrote about Austin City Council moving to keep large hyperscale data centers out of city limits. Then I followed up on what that meant for Texas specifically. That meant ERCOT’s record demand and the state’s audit of every data center in its interconnection queue. It also meant the race toward nuclear and natural gas to cover the gap.

Since then, I have kept pulling that thread. And the more markets I look at, the more obvious it becomes: this is not a Texas story. It is not even a regional story. It is a national build-out, happening at a pace and scale most people have not fully registered yet.

Here is what I am seeing across the country, what utilities and regulators are saying. And what it means for the people who build things for a living.

The National Number First

Electricity prices are up 40 percent cumulatively since 202, the fastest decade of price growth on record. Wholesale costs are running 6.1 percent higher year over year, nearly double the rate of overall inflation.

Utilities filed 9.4 billion dollars in rate increase requests in the first quarter of 2026 alone. For all of 2025, that number was 31 billion dollars, more than double what was requested in 2024.

To keep up, the industry is planning 1.4 trillion dollars in capital spending through 2030. That is a 27 percent jump over the prior year’s plan.

Data centers are not the only reason for any of this. Extreme weather, aging infrastructure, and utility profit growth are all in the mix. But in the neighborhoods sitting closest to new data center load, bills have risen as much as 267 percent. And every region I looked into points to the same driver behind its own numbers.

Texas — ERCOT

ERCOT set a new demand record in July at 91,308 megawatts. The forecast says that nearly doubles to roughly 175,000 megawatts by 2032. Texas is sitting on 474 gigawatts of interconnection requests in its queue, more than five times current peak demand. About 90 percent of that is data centers.

Governor Abbott has ordered an audit of every project in that queue. The audit looks at who brings their own power, who brings their own water, and who is actually footing the bill. The state has also committed 10 billion dollars through the Texas Energy Fund toward new natural gas generation. That is meant to cover the gap heading into 2027 and beyond.

That kind of urgency is exactly why the electrical engineering talent shortage keeps showing up as a bottleneck in every one of these buildouts.

The Mid-Atlantic — PJM

This is where the price shock is most visible today. PJM’s capacity price went from 28.92 dollars per megawatt-day in the 2024/2025 auction to 269.92 dollars in 2025/2026, a nine-fold jump. It then climbed another 22 percent to 329.17 dollars for 2026/2027.

Data centers accounted for 63 percent of that first spike, adding 9.3 billion dollars in costs that ratepayers are now absorbing. Households in Pepco’s D.C. territory saw bills rise about 21 dollars a month. Western Maryland saw roughly 18 dollars. Ohio, about 16 dollars. Starting this June, PJM ratepayers will collectively pay an additional 1.4 billion dollars a year in capacity costs alone.

The pressure point behind it is Virginia’s Dominion zone, long the densest data center corridor in the country. It is now projected to need more than 20,000 megawatts by 2037, up from an earlier estimate of just 5,700 megawatts.

The Midwest — MISO

MISO, which covers 15 states from Louisiana to Minnesota plus Manitoba, expects peak load to grow 35 percent by 2035. That is a jump from 121 gigawatts today to roughly 163 gigawatts. Under its mid-case scenario, data centers alone would make up a fifth of all MISO electricity by 2030. And a quarter of it by 2040.

MISO expects 8 to 14 gigawatts of new data center load to come online in just 2026 and 2027. The grid operator is candid that a lot of this is still uncertain, dependent on whether AI investment holds up. But it is planning generation and transmission for it regardless.

The Southeast — Georgia Power and Southern Company

Southern Company now has 17 gigawatts of contracted large load across its territory, up 6 gigawatts since the start of 2026. Data center electricity usage is up 49 percent year to date, 55 percent in the second quarter alone. The company is planning 81 billion dollars in capital spending through 2030. 68 billion of it is going straight into its regulated electric utilities.

The headline deal: Georgia Power signed a 25-year contract with OpenAI for a 3.2-gigawatt data center near Savannah. It is set to come online in 2028. It includes 1 gigawatt of flexible demand response built in. That is the first time the utility has formalized that kind of flexibility with a data center customer. Eight more gigawatts of projects are in advanced contracting.

What’s Being Built to Keep Up

Every region above is answering the same question differently, and none of the answers are simple.

Natural gas remains the fastest path to new baseload capacity, but it is getting more expensive by the month. Construction costs for new gas plants are up 66 percent in two years. Turbines alone are up 195 percent since 2019, and manufacturing waitlists stretch into the early 2030s. Projects now take 23 percent longer to complete than they did a few years ago.

That cost and timeline pressure is pushing the biggest buyers toward nuclear. Meta signed for up to 6.6 gigawatts of nuclear power over 20 years. That includes 2.1 gigawatts from existing reactors online now, with small modular reactors following in 2032 and 2035. Google is pairing renewables with long-duration battery storage rather than wait in the gas turbine queue. Gartner projects data center electricity demand will double nationally by 2030.

And transmission is its own bottleneck. MISO alone has floated an 8.8 billion dollar transmission plan. 3.1 billion of it is tied directly to data center load growth. That is one grid operator, in one planning cycle. Meeting that kind of demand is exactly the challenge covered in recruiting manufacturing, operations, and construction talent in today’s tight labor markets.

Why This Is a Construction Story, Not Just a Power Story

Here is what I keep coming back to.

Every gigawatt behind these numbers is a construction project. Gas turbines and the plants around them. Transmission lines and substations. Nuclear infrastructure and the specialized trades that come with it. Battery storage sites. And the civil, mechanical, electrical, and controls engineers, the superintendents, the MEP leads. And the project managers needed to build all of it. All of this sits on top of the data centers themselves. It relies on a national supply of skilled talent that was already stretched before any of this started.

The data center boom created one hiring wave. The power buildout behind it…in Texas, in the Mid-Atlantic, across the Midwest, throughout the Southeast, and in every other region I did not have room to cover here…is creating a second one. That second wave is layered right on top of the first, in nearly every state at once. The first wave is already straining the industry, and this second one is arriving before it has had a chance to catch up.

That is the story I will keep watching. Not because it is dramatic, but because it is the clearest signal I have seen in a long time. It shows where the next several years of construction and engineering demand are actually headed.
