Oracle sues Wisconsin regulators as it seeks relief from data center credit requirements

Tech giant Oracle is suing the Wisconsin Public Service Commission (PSC) in Ozaukee County Circuit Court, escalating a dispute over financial protection requirements for utility ratepayers. The lawsuit, filed on June 19, challenges the PSC's recently approved credit rating standards for data center developers, which Oracle contends are overly stringent and financially burdensome for its proposed data center in Port Washington.

In April, the PSC approved a "very large customer" rate structure for We Energies, the utility intended to power Oracle's facility. This structure mandates that data center developers with credit ratings below A- must provide substantial financial guarantees to shield existing ratepayers from potential financial risks. Oracle currently holds a BBB credit rating, placing its subsidiary involved in the Port Washington project in a position where it would need to provide over $100 million annually in cash deposits or letters of credit.

Oracle, supported by We Energies, is also asking the PSC to reconsider these requirements. The company's lawsuit argues that the commission acted outside its authority and without sufficient evidence to justify the A- credit bar, asserting it is not necessary to prevent harm to We Energies' customers or shareholders. Conversely, ratepayer advocates and clean energy groups, including Clean Wisconsin spokesperson Amy Barrilleaux, support the PSC's decision, emphasizing the need to protect other utility customers from potential losses.

The outcome of this legal and regulatory battle is expected to significantly influence future electrical service contracts for data center developments across Wisconsin. Notably, Northern States Power Company, an Xcel Energy subsidiary, has already submitted a proposal to the PSC for its own "very large customer" rate structure, setting its credit rating threshold at BBB-, which is a lower investment-grade category.
