Oracle has withdrawn its legal challenge against Wisconsin’s tax credit framework for data center development, clearing a regulatory hurdle for future campus approvals.
Oracle moved to voluntarily dismiss its lawsuit against Wisconsin’s Public Service Commission (PSC) on Aug. 17, nearly two months after the tech giant filed in Ozaukee County Circuit Court to challenge new credit rating requirements for data center developers in eastern Wisconsin. With the case now resolved, the credit rating rules—which aim to shield other Wisconsin ratepayers from financial fallout if a data center developer defaults—remain unchallenged. Oracle had previously argued that the requirements were overly stringent and could deter other companies from establishing operations in the state.
Oracle’s share price has begun to recover following a decline that started in early June and persisted for weeks after the company initiated legal action against the PSC. However, its credit rating remains well below the threshold required to avoid posting hundreds of millions of dollars in collateral as a condition for purchasing electricity for its Port Washington data center.
The Nashville-based cloud computing firm is a co-developer of the Port Washington data center campus. Alongside OpenAI and data center developer Vantage, Oracle expects the facility’s first phase to require 1.3 gigawatts of electrical generation capacity—enough to power approximately one million Wisconsin homes. We Energies, the state’s largest investor-owned utility, must meet the campus’ energy demands by a tentative deadline in late 2027.
The Port Washington facility’s energy consumption is so vast—roughly an order of magnitude greater than that of the Saukville steel mill, which until recently was Wisconsin’s largest electricity consumer—that state regulations mandate it purchase power under a specialized rate structure. In May, the PSC approved this rate structure for We Energies’ largest data center customers. Among other provisions, the commission’s order requires operators to fund the construction of new power plants needed to meet their energy demands. Because constructing such facilities can cost hundreds of millions of dollars, any unpaid debts could ultimately fall on We Energies’ other customers if a data center operator becomes insolvent. To protect ratepayers from potential cost shifts, the PSC established an A- credit rating threshold for data center operators seeking service from We Energies. Companies falling below this threshold must post substantial collateral in the form of cash or lines of credit.
Meeting this requirement could cost Oracle over $100 million annually in financial security payments. When the PSC approved the credit rating standards, Oracle held a BBB credit rating, largely due to aggressive borrowing to finance artificial intelligence ventures and its business partnership with OpenAI. On July 9, S&P Global Ratings—one of the “Big Three” agencies responsible for assessing corporate and government debt—downgraded Oracle’s rating to BBB-, placing it at the bottom edge of the investment-grade tier.
We Energies requested that the PSC reconsider the rule in June, arguing that the added costs could discourage other companies from operating in Wisconsin. The commission declined the request last month. During a recent quarterly earnings call, We Energies CEO Scott Lauber assured investors that the credit requirements do not threaten the viability of the Port Washington project. Oracle, however, filed its lawsuit in Ozaukee County Circuit Court as a backup to the regulatory reopener request. The June suit asked Judge Sandy Williams to “set aside, reverse, and remand” the credit rating requirements, contending they are not “needed to prevent harm” to We Energies’ other customers or shareholders.
Last month, the commission responded by accusing Oracle of attempting to evade regulatory scrutiny by seeking “to overturn over one-hundred years of established caselaw” and “dictate one-off preferential terms of service” with We Energies. Oracle’s attorneys filed a motion to voluntarily dismiss the lawsuit early Monday morning.
Ratepayer advocates who supported the credit rating requirements welcomed the lawsuit’s termination. “We were confident the PSC would win and that the consumer protection safeguards the CUB team sought would remain in place,” said Tom Content, executive director of Wisconsin’s Citizens Utility Board. “CUB believes the safeguards the PSC established are critical to protect We Energies customers from the risks of tech companies overextending their borrowing, calling into question the long-run solvency of those companies.” Clean Wisconsin spokesperson Amy Barrilleaux added, “This is an important win for Wisconsin since these safeguards — which We Energies claims would ‘narrow the pool of investors’ for AI data center projects — could be used as a blueprint in other parts of the state.”
The conclusion of this legal dispute does not guarantee smooth progress for the Port Washington project. Last week, the PSC voted to require the American Transmission Company (ATC)—the transmission utility responsible for connecting the data center to the grid—to restart its six-month application process for building the necessary transmission lines and substations. The commission cited a series of design changes ATC made after the review began. Although the redo leaves ATC with limited time to meet its December 2027 deadline for energizing the Port Washington data center, the company has not yet announced adjustments to its timeline.
Meanwhile, data center developer Cloverleaf Infrastructure has signaled interest in developing facilities within Madison Gas and Electric’s (MGE) service territory. Serving the core of the Madison metropolitan area, MGE is awaiting the PSC’s guidance on its own data center rate structure. Under MGE’s proposal, developers with credit ratings below A- would also be required to post collateral, though companies rated BBB+ would face lower collateral requirements than those rated BBB or below.
