Oracle has filed a lawsuit against Wisconsin's Public Service Commission (PSC) over new tariffs imposed on very large electricity customers. The company argues these tariffs, designed to protect ratepayers, could cost its Port Washington data center over $100 million annually. Local residents have expressed support for the PSC's policy.

Oracle has filed a lawsuit against Wisconsin's Public Service Commission, challenging tariffs the agency imposed on very large electricity customers — a policy designed to shield average ratepayers from financial risk if a major data center were to fail. The lawsuit centers on Oracle's data center in Port Washington, part of a $15 billion investment into the city's economy. The PSC added the tariffs in April, targeting so-called "very large customers," or VLCs, that do not carry a sufficiently high credit rating. Oracle holds a BBB rating, and the company argues the subsequent financial requirements could amount to more than $100 million annually. Port Washington neighbor Michelle Gauthier said companies of Oracle's scale should be prepared for exactly these kinds of financial obligations. "They're trying to say they can't afford a $100 million line of credit? That's ridiculous," Gauthier said. "I know it's not a planned expense, but unplanned expenses come up in the scope of a project this size."
