A map tracking the proliferation of data centers across the United States reveals several enormous campuses under construction with listed capacities exceeding 3 gigawatts. The live map, produced by Data Center Index, places the developments in Ohio, Texas, Louisiana and Utah, led by an 8-gigawatt project in Ohio. Projects of this scale "are indeed massive compared even to the largest data center campuses that existed just a few years ago prior to AI," Eric Masanet, a professor at the University of California, Santa Barbara, told Newsweek.
"Before AI, data center sites greater than 100 megawatts were considered very large by industry standards, and 100 megawatts is only 1/10 of a gigawatt," Masanet said. The largest listed on the site is SoftBank’s SB Energy’s 8GW PORTS-Pike Technology Campus, which Data Center Index said is being developed at the former Portsmouth Gaseous Diffusion Plant in Pike County, Ohio. The site says ground was broken on the project in March and that completion is expected in 2028.
Also listed as under construction is the Nexus Data Centers campus in Hubbard, Texas. Data Center Index estimated this project’s capacity at 7.7 gigawatts. Completion of this project is expected by October 2027, according to Data Center Index.
Next on the list is Meta’s Hyperion AI infrastructure project in Richland Parish, Louisiana, which Data Center Index identifies as a $50 billion development with a capacity of 5 gigawatts. The site says the 2,250-acre campus is being developed as a "Titan Cluster" for training next-generation large language models. Data Center Index says completion is expected in 2028.
The final project listed on Data Center Index as under construction and with a capacity greater than 3 gigawatts is Creekstone Energy’s Delta Gigasite southeast of Delta, Utah. It says completion is expected in 2027. A Creekstone Energy spokesperson told Newsweek the Delta Gigasite’s current generation was around 3 gigawatts, and that the campus is designed to scale toward 10 gigawatts over time.
Newsweek contacted the listed operators of all four projects for comment and confirmation of site details, via email, and awaits their responses. The rapid development of data centers across the country has become a political flashpoint ahead of November’s midterm elections, with residents and lawmakers voicing concerns over the facilities' potential electricity and water consumption, and environmental impacts. A Pew Research Center survey last month also found that Americans’ views toward the projects’ potential environmental and economic effects have turned more negative since the start of the year.
