‘A meaningful risk’: Oracle’s massive 1.3 GW Wisconsin AI campus faces severe power delays as grid review restarts — pushing customer delivery past 2027
Oracle's 1.3 GW AI data center campus in Wisconsin faces significant delays as regulators restarted the grid connection review process. The Public Service Commission of Wisconsin withdrew its completeness finding after American Transmission Company filed hundreds of additional documents altering the project scope. Consequently, customer delivery for the facility is now expected to be pushed past 2027.
- ▪Oracle's Project Lighthouse campus in Port Washington, Wisconsin, is designed to host four data centers with a total capacity of 1.3 GW.
- ▪Regulators restarted the review clock after ATC filed 564 additional documents between January and July 2026 that changed routes and cost estimates.
- ▪An administrative law judge found that ATC had not complied with orders to itemize each alteration to the project.
- ▪The campus cannot begin serving customers at scale until the required transmission infrastructure receives regulatory approval and is built.
