AI is driving a data-center power boom. Here are some of the biggest US projects being built.

Some Americans have new next-door neighbors: data centers.

The US has been building these computing facilities for decades, but development has ramped up dramatically in recent years as AI increasingly drives demand for computing power.

Business Insider compiled a list of some of these enormous US data-center projects to illustrate the scale of what’s being built.

Those on the list have at least 1 gigawatt of capacity and have broken ground.

Among the largest is a city-sized campus in Texas pursuing up to 17 gigawatts of power capacity.

Another in Ohio is aiming to have up to 10 gigawatts of data-center capacity, most of which OpenAI has contracted to use.

For reference, 1 gigawatt of electricity continuously supplied for a year could power roughly 835,000 average American homes.

In total, the Pew Research Center says the US has more than 3,000 operating data centers nationwide and over 1,500 more under development, mostly in rural areas.

According to data from the Energy Institute’s 2026 Statistical Review of World Energy, US data centers accounted for nearly 40% of global data-center electricity use in 2025, consuming about 313 terawatt-hours.

That’s more electricity than all of Australia used that year.

Planned capacity is the closest public proxy for how much computing these AI campuses can support, and that’s important because the electricity and water needed to run their servers and cooling systems can have major implications for local grids and sustainability.

Residents affected by developments in places like Texas and Utah have pushed back over concerns about noise, property values, and the effects on nearby communities.

New York has temporarily paused the construction of new large-scale AI data centers.

Still, the 2025 US Data Center Energy Usage Report from Berkeley Lab projects that data centers will consume 11.8% of US electricity by 2030, up from about 4.4% in 2023.

Oracle, SB Energy, xAI, Google, and Meta are among the leading developers and operators.

Here’s a closer look at some of the largest AI data-center campuses being built.
