Could the SPEED Act affect Oracle's nuclear power deal?
News Clip1:03Civic Media·Port Washington, Ozaukee County, WI

Could the SPEED Act affect Oracle's nuclear power deal?

Oracle's planned nuclear power arrangement in Wisconsin would not be canceled by the SPEED Act, but the legislation could change the federal wetlands review for high-voltage lines needed to power its Port Washington data center campus. The lines are part of American Transmission Company's Ozaukee County project, which would place construction mats across hundreds of acres of wetlands.

Analysis of Port Washington data center project says completion likely to be delayed until at least mid-2028 - BizTimes

An Aterio analysis says the $15 billion Vantage Data Centers project in Port Washington is unlikely to become operational before mid-2028 and could be delayed into 2029. The delay is tied to the required high-voltage grid interconnection, which needs approval from the Public Service Commission of Wisconsin after the commission closed and ATC refiled its application.

Microsoft, ratepayer advocates challenge ATC plan for data center transmission costs

Microsoft and Wisconsin ratepayer advocates are challenging a proposal by We Energies and American Transmission Company (ATC) to federal regulators regarding the allocation of transmission infrastructure costs for data centers. They argue the plan fails to adequately protect Wisconsinites from bearing the construction expenses, specifically referencing Microsoft's Mount Pleasant data center. ATC anticipates over $500 million in upgrades to connect the Mount Pleasant facility to the electrical grid.

Oracle Drops Lawsuit Opposing Wisconsin Data Center Credit Rules

Oracle has voluntarily dropped its lawsuit against Wisconsin's utility regulator, the Public Service Commission (PSC), over new credit rating requirements for data center developers. These rules require companies with lower credit ratings to post substantial collateral to cover electricity costs, intended to protect ratepayers from potential insolvency risks. The decision allows the PSC's credit rating standards, which Oracle had argued were overly stringent, to remain in place unchallenged.
