Microsoft's Fairwater AI data center campus in Mount Pleasant, Wisconsin, sits on the former Foxconn site. The first building was announced fully operational on June 23, 2026, and a second building is under construction for completion in 2028. Village approvals cover further buildings, now amended to seven in one campus plan. Capacity figures are Epoch AI estimates (369 MW IT now, 2,263 MW projected).

Vantage Data Centers' Lighthouse campus in Port Washington, Wisconsin, is the Stargate site for Oracle and OpenAI: four data center buildings on 672 acres with about 902 MW of critical IT load. The Common Council approved the development agreement in August 2025, groundbreaking followed in December 2025 and satellite imagery shows Buildings 1 and 2 roughly halfway roofed by July 2026. Vantage targets a 2028 opening, but a grid interconnection that needs a new Wisconsin PSC approval may push full load into mid-2028 or later.

Two Wisconsin PSC dockets address data center rate structures. Docket 6630-TE-113: We Energies proposed a 'Very Large Customer' rate class for customers with electricity demands above 500 MW (targeting hyperscale data centers like Microsoft in Mount Pleasant). Over 200 people joined virtual hearings on Feb 10-11, 2026, with ~85% of speakers voicing concerns about the proposal, urging that tech companies pay their full share of infrastructure costs. Critics argue the proposal would only require data centers to pay 75% of infrastructure costs, leaving 25% subsidized by the public. Docket 6680-TE-115: Alliant Energy's Individual Contract Rate Agreement to serve a data center campus in Beaver Dam (widely assumed to be Meta). The PSC required Alliant to refile the contract with fewer redactions after advocates raised transparency concerns. A coalition of 42 environmental justice, faith, conservation, and community organizations submitted formal comments voicing concerns about the proposals. VERIFIED 2026-05-26: On April 24, 2026 the Wisconsin PSC adopted a "full-benefits" model requiring data centers to pay 100% of their costs, extended the minimum term to 15 years, and lowered the threshold from 500 MW to 100 MW (removing the 75% capacity-only option) — a ratepayer-protection win.

Wisconsin SB 1061 would have imposed a moratorium on new data center construction until the state established a data center planning authority, prohibited cost-shifting to residents, eliminated subsidies, mandated public reporting, required 100% renewable energy, restored PSC planning authority, prohibited NDAs, and created enforcement structures. Introduced Feb 26, 2026 by Sens. Larson and Carpenter with cosponsors Madison, Hong, Moore Omokunde, Clancy, Cruz, and Tenorio. Companion AB 1099 is in the Assembly Energy and Utilities Committee. SB 1061 failed to pass pursuant to Senate Joint Resolution 1 on March 23, 2026.
