The US data center build-out in 9 numbers

Our Data Centers page maps every state, major market and top county and lets you model how much capacity comes online. Here are the numbers that matter, as of October 2026.

1About 49 GW operating

That is the capacity of US data centers that publish a power figure today. Many don't, so the true total is higher.

2About 70 GW under construction

More than is running today. If it is finished, published operating capacity more than doubles.

3About 276 GW planned

Roughly four times what is under construction. Most planned projects are waiting for grid connections, turbines or transformers.

4$85 billion a year in construction spending

US Census data shows monthly data-center construction spending running at about $85 billion a year in August 2026, up from under $2 billion a decade ago.

5Three states hold over 40% of the pipeline

Texas, Virginia and Pennsylvania lead. Local power prices, permitting and water decide where projects go.

6Northern Virginia is still the biggest market

Loudoun County's 'Data Center Alley' has the most operating capacity, but Dallas–Fort Worth, Phoenix and Atlanta are catching up.

7Over 5,000 facilities and projects

Operating sites, projects under construction, planned projects and paused ones.

8Power-first developers have some of the largest pipelines

Several of the biggest planned campuses belong to companies with little operating capacity today, which makes financing a key risk.

9Your scenario, your number

The model on the page lets you set how much of the pipeline gets built and see the result in gigawatts, reactors' worth of output and share of US electricity.

Why the gap between planned and built matters

Announcements are cheap; finished data halls are not. The ratio between planned and under-construction capacity shows how much of the pipeline is still waiting for power, permits or financing. A shrinking gap would mean projects are converting; a growing one would mean the bottlenecks are getting worse.

How to use the map and model

Switch the map between pipeline, under construction, operating and number of sites, and turn on market and county layers. Then use the sliders in the model to test your own view: how much of what is being built gets finished, and how much of the planned pipeline ever happens.

Frequently asked questions

How much power will US data centers use by 2030?

It depends on how much of the pipeline gets built. Our model's base case reaches roughly 2.5–3 times today's published capacity by 2030; you can change the assumptions on the page.

Which state has the most data center construction?

By pipeline power, Texas leads, followed by Virginia and Pennsylvania (October 2026).

Where does the data come from?

Facility aggregates from the US Data Center Map (dcmap.us), refreshed monthly, and construction spending from the US Census Bureau.
