Oracle Will Absorb $300 Million in Nuclear Costs to Spare Wisconsin Ratepayers. The Transmission Line Carrying That Power Just Got $1 Billion More Expensive.

Point Beach Nuclear Power Plant has run on the Lake Michigan shoreline in Two Creeks, Wisconsin since its two reactors came online in 1970 and 1972, quietly supplying something like 14% of the state's electricity for more than five decades. On October 2nd, Oracle asked for a slice of it: enough to help power an AI data center campus down the shoreline in Port Washington, and enough that Oracle agreed to pay extra for it, so the rest of Wisconsin wouldn't have to.

Under the agreement, Oracle will subscribe to between 10% and 20% of Point Beach's output — roughly 125 to 250 megawatts of the plant's 1,230-megawatt capacity — to help power Project Lighthouse, the $15 billion, 672-acre data center campus Oracle is building in Port Washington with Vantage Data Centers and OpenAI. We Energies, which buys Point Beach's power from owner NextEra Energy under a long-term contract, says Oracle's subscription will save its other customers roughly $300 million in fuel costs. The companies haven't fully reconciled over what period: Oracle's own figure covers 2027 through 2033, while a We Energies spokesperson told Wisconsin Watch the savings could land over five years instead. Either way, it's the same cost-allocation instinct behind DTE's contract with Google in Michigan and Black Hills Corp's deal with Google in Wyoming: make the customer causing the new cost absorb it, rather than let it flow into everyone's bill by default.

The deal isn't done. It still needs sign-off from Wisconsin's Public Service Commission, with formal filings expected by the end of the year. On the evidence ladder we use to grade claims like this, an announced agreement with named numbers sits well above a vague pledge — but it's still one rung below an order a regulator has actually signed.

The line carrying it isn't so settled

Here's the part a press release about nuclear power doesn't mention: getting that electricity from the grid to the data center requires a new transmission line, and that line's price tag has been anything but stable. American Transmission Co. originally proposed the Ozaukee County Distribution Interconnection Project at an estimated $1.3 to $1.7 billion. In August, Wisconsin's Public Service Commission voted unanimously to revoke its "completeness" determination on that application and sent ATC back to redesign it.

ATC's reworked version, filed in September, carries a new price: $2.48 to $2.72 billion, which Tom Content, executive director of the Citizens Utility Board of Wisconsin, says could make it the single most expensive transmission project he's seen in the state. He calls the shifting estimate "a moving target," pointing to route changes and new bypass lines that keep altering the number, with ATC still eyeing a possible completion date in December 2027. Roughly $1.1 billion of the total is tied specifically to a new system at a substation in Decker, built to serve the data center's load directly.

Who actually pays for it is still unresolved. Both the state PSC and federal regulators at FERC have to sign off before the project can move forward, and advocates say the open question — whether Oracle and Vantage get billed directly for the capacity built specifically for them, or whether the cost spreads across We Energies' and neighboring utilities' broader customer base — needs an answer before the project works its way into anyone's rates. It's the exact fight Virginia just resolved differently, cutting its own data-center transmission line's residential cost by two-thirds by billing the large loads directly instead. I think that gap — a company paying extra for the electrons but nobody yet pinned down for the wire next to it — is exactly what a one-line "our data center runs on nuclear power" headline is built to paper over.

A shortcut on the environmental review, too

The power questions aren't the only ones still open on this site. In July, Sierra Club Wisconsin and Midwest Environmental Advocates sued the state Department of Natural Resources in Ozaukee County Circuit Court, arguing the agency skipped a full environmental impact statement it had initially told the companies it would require. Public records the groups obtained show DNR staff told Vantage's representatives early on that a detailed EIS was coming, then the agency settled for a shorter environmental analysis after Vantage indicated the fuller review would, in the groups' words, "kill the project." The suit argues that's a violation of the state's own environmental review law, and it's still pending.

Part of what that shortened review didn't fully examine, the suit says, is Foundry Ridge, the new gas plant We Energies is building in Walworth County specifically to help power this campus. It's a separate filing from Fox North, a second, larger gas plant the company proposed the same week in Wrightstown, which it has declined to say is data-center-related at all. "It's astounding how much We Energies is investing in gas," says Ciaran Gallagher, energy and air manager at Clean Wisconsin — a seventh new gas-plant proposal in the state in roughly two years, by environmental groups' count.

Put the three threads next to each other and you get a more honest picture than any one of them gives alone. The generation question — where the electrons actually come from — is arguably the best-resolved part of this project, with a named company absorbing a named cost to protect ratepayers who have nothing to do with it. The transmission question is still climbing the evidence ladder, with a price tag that's grown by roughly a billion dollars in a matter of months and no settled answer on who pays it. And the environmental review that was supposed to vet all of it got shorter, by the regulator's own account, after the developer pushed back. A data center's power story is never just one deal. It's whichever of these three you happen to be looking at when the press release goes out.
