Every project in Wisconsin on the atlas's capital-at-risk record: the action taken, who took it, and the announced capital affected. Restarts and reversals are recorded with the same weight as blocks.

Project	Developer	Jurisdiction	Action	Capital
Lighthouse campus (Port Washington) litigation Jul 10 2026	Oracle / Vantage Data Centers	Port Washington, Ozaukee County	Nearly 1GW Stargate-partnership campus. The Wisconsin PSC's April 2026 order set financial guarantee requirements for hyperscale customers (see the Wisconsin PSC jurisdiction note). On 6 August 2026 the Wisconsin PSC told American Transmission Co. to resubmit its application for the roughly 100-mile power line project serving the $15 billion Port Washington campus, citing about 564 changes made after the application was deemed complete. ATC refiled on 14 September 2026 at an estimated $2.5 billion to $2.7 billion, up from $1.6 billion, with Oracle paying most of the cost; Vantage says the campus remains on track for 2028. Ozaukee County Circuit Judge Adam Gerol dismissed Great Lakes Neighbors, Inc. v. City of Port Washington Joint Review Board, a challenge to the creation of Tax Incremental District No. 5 for the project, on Wednesday 16 September 2026 on pleading grounds, without ruling on whether the district complied with Wisconsin law; the group said it will pursue other avenues.	$15.0B
Madison campus moratorium Jan 13 2026	Vantage / OpenAI / Oracle	Madison	One-year moratorium to study impacts	$15.0B
QTS DeForest / Vienna campus cancelled Jan 27 2026	QTS Data Centers	DeForest / Town of Vienna, Dane County	QTS's $12B proposal required annexing 1,600 acres from the Town of Vienna into DeForest. On Jan 27, 2026 village staff determined the project 'not feasible in DeForest' after ~7 months of undisclosed talks and recommended the village president reject the annexation petition; scheduled Feb 3 board vote and Feb 9 public hearing were rendered moot.	$12.0B
Project Nova cancelled October 9, 2025	Microsoft	Village of Caledonia	Microsoft cancelled its 244-acre, 900 MW Caledonia data center (Project Nova) after a 2,000-signature petition and strong community opposition forced a rethinking of the plan.	$7.0B
Caledonia campus withdrawn 2025; $4.0B marked as estimate in source	Microsoft	Racine County	Zoning denied Apr 2025; Microsoft withdrew Sep 2025	$4.0B
Menomonie Data Center cancelled September 24, 2025	Balloonist LLC	Menomonie	Menomonie signed an NDA with Balloonist LLC in February 2024, over a year before announcing the $1.6B data center proposal in July 2025.	$1.6B
Menomonie data center (Balloonist LLC) paused Paused by the mayor in September 2025; zoning rewrite under way in mid 2026	Balloonist, LLC	City of Menomonie	In September 2025 Mayor Randy Knaack halted city support for the project, writing to Balloonist that the city was not interested in negotiating incentives, after resident pushback over secrecy, water and energy use. Civic Media reported in July 2026 that the paused tax increment negotiations had stalled development and that the city, which could not otherwise block a use that fell under its warehousing definition, was preparing a data center zoning ordinance for introduction on 4 August 2026.	$1.6B
Project Cornmaze data center campus (Towns of Turtle and Beloit) moratorium Cost agreements rejected and moratorium process started 29 July 2026 (Turtle) and 31 July 2026 (Beloit); Turtle 12-month moratorium since approved, adoption date not stated	Panattoni Development Co.	Town of Turtle and Town of Beloit	On Wednesday 29 July 2026 the Town of Turtle Board of Supervisors unanimously rejected a revised cost-reimbursement agreement with Panattoni Development for a proposed $1 billion, 2 million sq ft hyperscale data center campus spanning the towns of Turtle and Beloit, and passed a resolution starting the process for a 12-month moratorium on developments of more than 10,000 sq ft. The Town of Beloit board unanimously took the same two actions on Friday 31 July 2026. The Beloit Daily News later reported that the Turtle board has approved the 12-month moratorium (adoption date not stated). Turtle board chair Roger Anclam, who had voted for the original agreement in early July 2026, faces a recall election over it. Panattoni said it would review the actions and determine a path forward.	$1.0B

American Transmission Co. power line project serving the Port Washington (Lighthouse) campus for Vantage, Oracle and OpenAI delayed Completeness revoked 6 August 2026; application refiled 14 September 2026	American Transmission Co. (for Vantage Data Centers, Oracle and OpenAI)	Public Service Commission of Wisconsin	On 6 August 2026 the three-member Wisconsin PSC voted unanimously to revoke the December 2025 completeness determination for ATC's transmission application and ordered it resubmitted, citing about 564 amendments to route, scope, costs and environmental studies. The commission said the decision did not reject the project but reset review, jeopardizing ATC's late-2027 completion target. ATC refiled on 14 September 2026 with a revised cost of $2.5 billion to $2.7 billion, up from $1.6 billion, and estimated about 17 months of construction after a six- to 12-month approval process. Oracle will pay for most of the project, and ATC said the campus will not be served until the transmission facilities are in service. Research firm Aterio said in a report of 30 September 2026 that the campus could miss Oracle's target of delivering capacity in the second half of 2027 because ATC cannot start building until the PSC approves the refiled application: its base case puts partial grid power in December 2027 and full supply in October 2028, and an extended review could push those to June 2028 and April 2029. This is a third-party estimate, not a regulator or company statement; The Register said Oracle had been asked for comment.	n.a.

DC Rapids former paper mill data center other Denial recommended 7-0 on 16 September 2026; Common Council action pending	DC Rapids LLC	City of Wisconsin Rapids	The Wisconsin Rapids Plan Commission voted 7-0 on 16 September 2026 to recommend that the Common Council deny DC Rapids LLC's conditional use and site review applications to redevelop the former paper mill site as a data center. Staff identified 33 shortcomings, including missing electric utility approval, employment and shift projections and construction traffic details.

Financing

Financing transactions tied to Wisconsin sites

Transactions the atlas ties to a named site in Wisconsin: joint ventures, project bonds, credit facilities, leases and power agreements. Amounts are as stated; overlapping commitments are never summed.

Parties	Instrument	Amount	Date	Site	Sources
Oracle + We Energies (WEC Energy Group) + NextEra Energy (Point Beach owner) On Friday 2 October 2026 Oracle and We Energies announced an agreement under which Oracle would subscribe to between 10% and 20% of the generation We Energies buys from NextEra's Point Beach Nuclear Plant in Manitowoc County, to help supply the Port Washington campus (Project Lighthouse) that Oracle is developing with OpenAI. The Journal Sentinel reports the subscription at 125 to 250 MW, roughly 10% to 20% of the 1.3 GW campus's consumption. We Energies and Oracle say the arrangement would spare other customers about $300 million of fuel costs over five years; that is a ratepayer savings estimate, not a contract value. The agreement requires approval by the Public Service Commission of Wisconsin, and Oracle expects the proposal to be filed by the end of 2026.	power supply agreement	n.a.

Policy context

What governs a data center in Wisconsin

Wisconsin (statewide summary)state

C.4 floors: 500 MW (Caledonia); $5.6B cancelled plus $15B under moratorium; 5 projects.

Wisconsin's 2025 cancellation wave totals $5.6B across four projects, and Madison placed the $15B Vantage/OpenAI/Oracle campus under a one-year moratorium on January 13, 2026.

Wisconsin (PSC financial guarantee rule for hyperscale customers)state

Data center customers with credit ratings below A- must post cash or letters of credit under We Energies' approved large-customer rate structure

The Wisconsin PSC let a We Energies rehearing petition expire on 9 July 2026 without any commissioner moving to reopen the case, leaving in place financial guarantees, approved in April 2026, that Oracle said would cost about $100 million a year. Oracle, which is developing the $15 billion Port Washington campus with OpenAI and Vantage, filed a notice of voluntary dismissal of its June lawsuit in Ozaukee County Circuit Court on 17 August 2026, and the PSC said it stands behind its decision.

The policy layer for Wisconsin lives in three companion references: the Wisconsin Data Center Moratorium Tracker for every state measure and local moratorium on record, the Water Tracker for the water rules that touch a site, and the Grid Operator Watchlist for the large-load rules of the RTO or utility that decides whether it can energize.

Figures beside each state are named sites and blocked, delayed or restricted projects.

Part of the North American Data Center Capital Atlas, refreshed every Tuesday, Thursday and Saturday. Announced commitments overlap one another and overlap reported capital expenditure, so this page shows disclosed floors and never adds them into a single deployment figure. Informational, not investment or legal advice.

The SAVRN reference set

Seven references, one system

Capital, delay, policy, water, grid, permits and scarcity are one system seen from seven sides. Each reference is primary-sourced, refreshed on a schedule, and links into the others, so a project can be followed from the money committed to the docket that stopped it.

Delay Watchlist

Project-level slippage: named projects, jurisdictional actions, utility and federal dockets, SEC disclosures, and the interconnection queue.

Open the watchlist →

Moratorium Tracker

The policy layer: every state measure and local moratorium mapped and cited, with one page per state.

Open the tracker →

Water Tracker

Every federal, state, local and interstate water measure that touches a data center, plus a fifty-state water ledger.

Open the water tracker →

Grid Operator Watchlist

ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISO-NE and FERC: the large-load rules, filings and queue positions that decide whether a site can energize.

Open the watchlist →

Permits and Power Development

Data center and substation permits, large loads in the interconnection queues, and the power plants planned to serve them, refreshed hourly from public records.

Open the permits tracker →

SAVRN Scarcity Tracker

Eleven primary-sourced indicators of AI infrastructure scarcity, one composite index, read against the token index, SAVRN's own cost basis and the frontier ceiling.

Open the scarcity tracker →
