State-level measures in Wisconsin
Every statewide moratorium, pause, siting restriction, or tax-incentive rollback in Wisconsin we can verify against a primary source. Strongest status first.
| Measure | Status | What it does | Source |
|---|---|---|---|
| Wisconsin Legislature (Act 16 data-center TID exception)Wisconsin: Governor Tony Evers signed Assembly Bill 140 (now 2025 Wisconsin Act 16), which created statutory exceptions from the standard 12% equalized-value | In force 2025-07 | Governor Tony Evers signed Assembly Bill 140 (now 2025 Wisconsin Act 16), which created statutory exceptions from the standard 12% equalized-value cap on Tax Increment Districts specifically for TID No. 5 in Port Washington and TID No. 10 in Beaver Dam, but only if all project costs are tied to a 'certified data center.' This carve-out paved the way for the Vantage data center's $458 million TID financing structure, which would otherwise have been impossible under standard TID law. Critics argue the state-level subsidy was passed before residents had any meaningful chance to weigh in. | |
| Wisconsin (statewide PSC rate hearing)Wisconsin: Two Wisconsin PSC dockets address data center rate structures. | Proposed 2026-02 | 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. 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. | |
| Months after session, weeks before election, Republicans propose repeal of data center tax break | Proposed 2026-10 | A group of four legislative Republicans proposed legislation to repeal the sales tax exemption for data centers that was included in the 2023-25 budget. The proposal was announced weeks before an election and months after the legislative session ended. | |
| AB 302Relating to: a sales and use tax exemption for data center equipment or software. (FE) | Failed / vetoed 2024-04 | Wisconsin AB 302 (2023): Relating to: a sales and use tax exemption for data center equipment or software. (FE).

| AB 840Wisconsin AB 840 / SB 843 (Rep. Shannon Zimmerman R-River Falls, Sen. Romaine Quinn R-Birchwood), a GOP-led data center bill, passed the Assembly in January | Failed / vetoed 2026-01 | Wisconsin AB 840 / SB 843 (Rep. Shannon Zimmerman R-River Falls, Sen. Romaine Quinn R-Birchwood), a GOP-led data center bill, passed the Assembly in January 2026 by a 53-44 mostly party-line vote (2 Democrats yes, 1 Republican no). The bill would have prevented data center operators from passing energy costs onto residential consumers, required them to pay for their own generation/transmission infrastructure, mandated closed-loop water systems, required annual water use reporting, and required reclamation bonds. However, the Wisconsin Senate adjourned without taking up AB-840, or any data center regulation bill, on the floor. Democrats and several construction unions opposed the bill due to lack of prevailing wage requirements and concerns over energy consumption. The competing Democratic Data Center Accountability Act (SB 729/AB 722) by Sen. Habush Sinykin and Rep. Stroud, requiring 70% renewable sourcing and a new very-large-customer rate class, was heard in the Senate Utilities Committee on Feb 17, 2026 but never advanced. | |
| SB 729Wisconsin SB 729 / AB 722, the Data Center Accountability Act, authored by Sen. Jodi Habush Sinykin (D-Whitefish Bay) and Rep. Angela Stroud (D-Ashland) | Failed / vetoed 2026-01 | Wisconsin SB 729 / AB 722, the Data Center Accountability Act, authored by Sen. Jodi Habush Sinykin (D-Whitefish Bay) and Rep. Angela Stroud (D-Ashland), would have required data centers to source at least 70% of electricity from renewables to qualify for state tax exemptions, created a 'very large customers' rate class with rate cases every 2 years, required prevailing wages, and required water/energy transparency. SB 729 was introduced Dec 2, 2025 (with ~12 senate cosponsors and ~25 House cosponsors) and received a Senate Utilities Committee hearing Feb 17, 2026. AB 722 (the Assembly companion) was introduced Dec 3, 2025. Both bills failed to pass pursuant to Senate Joint Resolution 1 on March 23, 2026, leaving Wisconsin without statewide data center regulation. | |
| WisconsinWisconsin: Senate Bill 969, authored by Sen. Andre Jacque (R-New Franken), would prohibit NDAs between data center companies and municipalities | Failed / vetoed 2026-02 | Senate Bill 969, authored by Sen. Andre Jacque (R-New Franken), would prohibit NDAs between data center companies and municipalities, while still allowing withholding of genuine trade secrets. The bill was prompted by a Wisconsin Watch investigation revealing at least four communities had signed secrecy deals hiding billion-dollar data center plans. Rep. Clint Moses (R-Menomonie), author of the companion Assembly bill, called the measure 'really about trust.' Passed Senate Utilities Committee 4-1, but the Senate adjourned the 2026 session without a floor vote. | |
| AB 1099 / SB 1061Moratorium on operation of data centers | Failed / vetoed 2026-03 | Would impose a moratorium on operating data centers absent a statewide planning authority, cost-shift prohibitions, and renewable-energy requirements; AB 1099 failed pursuant to Senate Joint Resolution 1. | |
| SB 244Relating to: modifying the sales and use tax exemption for qualified data centers. (FE) | Failed / vetoed 2026-03 | Wisconsin SB 244 (2025): Relating to: modifying the sales and use tax exemption for qualified data centers. (FE).

What does bind large loads in Wisconsin
A moratorium is only one way a data center gets stopped. The grid operator decides whether it can connect at all, and on what terms. Wisconsin sits in 1 footprint.
MISODominant
Faster parallel studies and a co-located generation fast track, not a pause.
Effectively the entire state is MISO (ATC transmission in east/central; Xcel NSP-W in west) — not a genuine multi-RTO state.
States next door
4 of the 4 states bordering Wisconsin have at least one data-center measure on record. Restrictions tend to travel between neighbors, so this is usually where the next one comes from.
Data centers in Wisconsin

How to read this page
In force = a moratorium, siting restriction, or tax-incentive rollback that is currently enacted, by statute or executive order. Paused = a temporary hold on new incentives or applications. Proposed = introduced and still pending. Failed / vetoed = died in committee, was voted down, or was vetoed.
This page is generated from the same primary-sourced dataset as the national U.S. Data Center Moratorium Tracker and is re-checked on the same weekly cycle, whether or not anything changed. Legislative status changes quickly; it is informational, not legal advice. Spot something out of date in Wisconsin? Tell us.
Companion references: the Data Center Grid Operator Watchlist for the interconnection and curtailment rules that bind here, the Data Center Water Tracker for water mandates, and the Data Center Delay Watchlist for named projects.
Why Wisconsin is pushing back
The objections repeat from state to state: strain on the electric grid, water drawn for cooling, and the sense that a facility takes local resources without giving much back. SAVRN builds AI factories designed around those three objections: on-site power that does not lean on the public grid, direct-to-chip cooling that does not consume municipal water, and a training institute that puts local people to work inside the building.
