OpenAI plans to deploy another Stargate data center cluster, this time in Port Washington, Wisconsin. The project will be developed by the generative AI company, alongside Oracle and Vantage Data Centers, on a site from powered land provider Cloverleaf Infrastructure. The facility is the ‘unnamed site in the Midwest’ that OpenAI referenced when it disclosed plans for five Stargate data centers in the US, alongside the existing Abilene, Texas, campus. The other known projects are in Doña Ana County, New Mexico, and in Shackelford County, Texas. That latter facility is also expected to be from Vantage, with the company working on a 1.4GW campus. Altogether, the US Stargate campuses are planned to grow to 4.5GW of IT capacity. 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.

Full report: OpenAI, Oracle, and Vantage Data Centers plan to build a data center in Wisconsin called Lighthouse, costing $15 billion and set to open in 2028, as part of Stargate.
