Oct 23, 2025 | Posted by Abdul-Rahman Oladimeji

OpenAI plans to deploy another Stargate data center cluster, this time in Port Washington, Wisconsin, to be developed alongside Oracle and Vantage Data Centers, on a site from powered land provider Cloverleaf Infrastructure.

The Wisconsin site, codenamed Lighthouse, is planned to support 'close to a gigawatt' across four data centers. Construction will begin 'soon' and is scheduled to be completed in 2028. Vantage said that it will develop 500 of the 672 total acres of the site, with the rest preserved for natural biodiversity. More than 2,000 native trees will be planted, along with other native landscaping and an eight-foot planted berm with native species for natural sound mitigation.

“Expanding Stargate to Wisconsin is another major step toward building the infrastructure that will help ensure everyone can benefit from AI,” said Peter Hoeschele, OpenAI’s vice president of industrial compute. “This project will create good jobs, advance zero-emission energy, and boost the local economy—all while expanding capacity without raising rates for local consumers. We’re grateful to our partners at Oracle, Vantage, and We Energies, as well as the many manufacturers, builders, and suppliers across the region, for helping bring this ambitious vision to life.”

Dana Adams, president of North America, Vantage Data Centers, added: “As demand for data centers expands beyond traditional hubs, the upper Midwest has become a critical and strategic market for Vantage Data Centers and our customers.
