Meta Unveils Series of Major Nuclear Energy Deals to Power U.S. Data Centers, Support Clean Energy Goals
Meta announced that it has signed a series of large-scale nuclear power agreements to support its expanding U.S. data center energy needs and clean energy goals.
- Main announcement: Meta has committed to agreements supporting up to 6.6 GW of nuclear energy by 2035, including: TerraPower funding for two Natrium plants (345 MW baseload each, boostable to 500 MW for >5 hours, with rights to energy from up to six additional units; additional units anticipated as early as 2032); Oklo funding to advance a 1.2 GW power campus in Pike County, Ohio (Phase 1 targeted online as early as 2030, full incremental capacity by 2034); Vistra 20-year PPAs for more than 2.6 GW of zero-carbon energy (including 2,176 MW of operating generation and 433 MW of uprates) with Meta purchases beginning late 2026 and additional capacity added through 2034; and a prior June 2025 Constellation Energy agreement extending a plant life to supply 1.1 GW for 20 years.
- Background and implementation details: The deals resulted from a U.S.-focused nuclear RFP launched by Meta in late 2024; TerraPower’s Natrium design integrates a sodium fast reactor with molten salt energy storage; Oklo is working with the U.S. Department of Energy and National Laboratories on advanced fuel recycling and has purchased over 200 acres in Pike County; Vistra’s agreements mark the largest nuclear uprates supported by a corporate customer in the U.S. to date. Implementation timelines are explicit: Constellation deal announced June 2025; Vistra purchases begin late 2026 with capacity additions through 2034; TerraPower additional units as early as 2032; Oklo Phase 1 as early as 2030 and full campus by 2034.

New Data Center Developments: January 2026
Vantage Data Centers broke ground on the Lighthouse data center project in Port Washington, Wisconsin.
- Project details: Lighthouse is a four-data-center campus delivering 902 MW of IT capacity, driven by a $15 billion investment as part of Oracle and OpenAI’s Stargate initiative; the development positions the site for hyperscale AI deployments and is presented as a regional economic infrastructure project.
- Additional facts and background: Major energy and footprint moves this month include Alphabet’s acquisition of Intersect Power for $4.75 billion in cash (plus assumption of existing debt) to secure clean energy for Google data centers; Nscale’s $865 million commitment for a 10-year, 40 MW colocation agreement in North Carolina; TikTok’s >$37.7 billion investment plan for a Brazil data center with Omnia and Casa dos Ventos; Brookfield and Qai’s $20 billion AI infrastructure JV in Qatar; and regulatory/energy items such as Ireland lifting a de facto moratorium requiring on-site generation or batteries to meet full demand for grid connections.

Trump’s AI push breathes life into an old pollution scourge
The EPA under Administrator Lee Zeldin plans to loosen enforcement of a 2024 Biden-era coal ash rule, proposing regulatory changes and potentially granting a three-year cleanup extension to 11 power plants for 13 unlined coal ash dumps.
- Main action: EPA plans to propose amendments to the 2024 coal ash rule and is considering a three-year extension (to Oct. 17, 2031) for a subset of plants; the proposal would apply to 11 plants and 13 unlined ash dumps (each spanning more than 40 acres), and the agency will accept comments through February 6, 2026. The agency says the extension aims to promote grid reliability amid rising demand from AI data centers.
- Background and details: The 2024 rule had expanded oversight to legacy ash dumps after earlier exemptions; EPA and companies cite implementation challenges. Examples: NIPSCO/Schahfer previously expected to close by 2028 but EPA proposed extension to Oct. 2031; PacifiCorp stopped burning coal on Dec. 31 and will not use the extension (stop disposing ash by Sept. 30); several plants (Naughton, Baldwin) have reported groundwater exceedances of contaminants such as arsenic, lithium, fluoride and radium. EPA has not publicly confirmed compliance status for the 11 plants identified.
