US Department of Energy Approves US$4 Billion Loan for Vistra Nuclear Upgrades

Oracle and We Energies announced a nuclear power subscription deal on October 2, 2026, under which Oracle will take 10-20% of the output from the Point Beach Nuclear Plant, or 125-250 megawatts, for the $15 billion Lighthouse Campus AI data center in Port Washington, Wisconsin. The campus, co-developed by Oracle, OpenAI, and Vantage Data Centers as part of the broader Stargate initiative, is designed to house close to 1 gigawatt of AI capacity within a 1.3 gigawatt total electrical footprint, with completion targeted for 2028. Oracle has committed to fully funding the energy costs for its portion, and the deal is the primary driver of a proposed $176 million electric rate hike for We Energies customers in 2027, accounting for roughly 20% of that increase, while the utility projects the arrangement will save customers approximately $300 million in fuel costs between 2027 and 2033. The subscription, a first-of-its-kind model in Wisconsin, requires approval from the Wisconsin Public Service Commission, which is weighing whether to require tech companies to cover 100% of new power plant costs. The deal is part of an industry-wide pivot in which Big Tech has contracted over 10 gigawatts of new nuclear capacity in the United States over the past year, including Microsoft's 20-year power purchase agreement for the 835-megawatt restart of Three Mile Island, Amazon's acquisition of a nuclear-adjacent Pennsylvania campus for over $650 million and its $500 million investment in X-energy small modular reactors, and Google's order of 500 megawatts from Kairos Power. Data center power demand reached 29.6 gigawatts by late 2025, equivalent to the peak demand of New York state, and the International Energy Agency projects it will rise by 130% by 2030, even as U.S. nuclear output stayed largely flat between 2020 and 2025 and no small modular reactors are under construction in the country.

The U.S. government plans to lend Vistra about US$4.2b to expand nuclear power output, a move that spotlights utilities tied to nuclear energy as data centers, EVs, and crypto miners drive demand for reliable electricity. The article highlights three nuclear-exposed U.S. utilities as a sample from a broader screen that surfaced 9 more power companies. Entergy, with roughly US$13.4b in revenue and a market value of about US$48b, sees approximately 7 to 12 GW of hyperscale data center potential and 3 to 5 GW of traditional industrial demand in its territory, alongside signed agreements with AWS and Meta supporting roughly 8.5% to 9% annual retail sales growth. Ameren, a US$27.6b holding company, owns the Callaway nuclear facility and is studying more nuclear capacity, with 2.8 gigawatts of signed electric service agreements, 3.4 gigawatts of construction agreements, and a further 4 gigawatts of projects with completed interconnection studies in its Missouri territory. Deep Fission, with a market value of roughly US$305 million, develops small modular nuclear reactors buried about a mile underground for utilities, data centers, heavy industry, and government clients.
