During the June 7-July 6 lookback window, Wisconsin Watch reported that Oracle filed a June 19, 2026 lawsuit challenging Wisconsin PSC credit-rating requirements attached to We Energies' data-center tariff. Oracle and We Energies were also asking the PSC to reconsider requirements that could require the Oracle subsidiary behind the Port Washington project to post more than $100 million per year in cash deposits or letters of credit.

Recent litigation shows Wisconsin data-center policy remains contested and unresolved; it does not show Tiffany ending Wisconsin data-center subsidies.

The Wisconsin PSC said it approved major modifications to We Energies' very-large-customer tariff for data centers, including a 15-year minimum term, expanding applicability from 500 MW to 100 MW, addressing transmission cost shifting, removing a capacity-only option, and requiring very large customers to pay 100% of their generation-resource costs. The PSC also stated it does not regulate data-center construction or operations.

This is a partial state regulatory action against utility cost-shifting for data centers, but it does not end Wisconsin tax subsidies and is not action by Tiffany.

The Wisconsin PSC modified Alliant Energy's electric service agreement for a Beaver Dam data center by strengthening the termination charge, adding reporting requirements, imposing financial safeguards, requiring the customer to contribute to the statewide energy-efficiency and renewable-energy program, and ordering Alliant to file a stand-alone large-load tariff for future data-center customers.

Another partial state utility-protection action, but not a statewide end to subsidies and not attributable to Tiffany.

Wisconsin Watch reported that Wisconsin's 2023-25 state budget granted data centers a sales-tax exemption, leaving major projects in Beaver Dam, Mount Pleasant, Port Washington, and Verona exempt from state and local sales taxes on construction and equipment. It cited a Legislative Fiscal Bureau projection of $1.5 billion in forgone state sales-tax revenue during construction plus $369 million annually after facilities are built.

The core Wisconsin data-center tax subsidy remains in place and is projected to be large, which weighs against delivery of a promise to end such subsidies.

Wisconsin's official lobbying database identifies 2023 Senate Bill 308 as relating to a sales and use tax exemption for data-center equipment or software. The page lists lobbying principals including Microsoft, Alliant Energy, WEC Energy Group, TechNet, and others as 'For' the bill, with 205 total hours of lobbying effort on the matter.

Official state lobbying records corroborate the policy path for creating data-center sales/use tax exemptions rather than ending them.

In the lookback window, Wisconsin Watch reported that a proposed up-to-$2 billion Grant County data center appeared all but dead after developers stopped responding, while Cassville and other Grant County governments adopted data-center moratoriums. The same report noted developers were enthused that the project might qualify for a state sales-tax exemption expected to be worth billions statewide.

Local opposition and moratoriums blocked or chilled one project, but the statewide subsidy framework remained available and no Tiffany action was identified.
