Abstract

Wisconsin has more than $15 billion of AI infrastructure development riding on a power schedule that is no longer settled. In Port Washington, Vantage Data Centers is building the Lighthouse campus across 672 acres, with four data centers and 902 megawatts of critical IT load. All four buildings are under construction, and Oracle has said customer delivery is expected to begin in the second half of 2027. But on Aug. 6, the Public Service Commission of Wisconsin revoked its earlier determination that American Transmission Co.’s transmission application was complete. As of Sept. 9, the public record did not show a revised energization date following that regulatory reset. That gap matters because a campus can be physically built and commercially committed while still producing a much weaker investment return if the electricity arrives late
