Meta announced on January 9, 2026 a set of nuclear agreements to secure up to 6.6 gigawatts of power by 2035 for its data centers, including the Prometheus AI supercluster being built in New Albany, Ohio.1 Utility Dive 2026-01-09 Meta announced deals on January 9, 2026 to secure up to 6.6 GW of nuclear power by 2035 across Oklo, Vistra, and TerraPower for its Prometheus supercluster in New Albany, Ohio, following a June 2025 Constellation agreement, with power in the PJM region. Open source The deals span three companies: Vistra, for more than 2.1 gigawatts through 20-year purchase agreements at existing plants plus uprates; TerraPower, funding two new Natrium sodium fast reactors with rights to six more; and Oklo, a 1.2 gigawatt campus in Pike County, Ohio targeted to come online as early as 2030.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source The stake is that a social-media company is now one of the larger corporate nuclear buyers in the United States. We assess, with high confidence, that these are power-procurement commitments dated years out, not near-term capacity, and that the timeline is the most important fact in the announcement.

What is firm and what is a promise

The 6.6 gigawatt headline blends very different kinds of commitment. The firmest piece is Vistra: more than 2.1 gigawatts of 20-year power purchase agreements from operating reactors at Beaver Valley in Pennsylvania and Perry and Davis-Besse in Ohio, plus uprates at the Ohio plants.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source That is real, existing generation being contracted, and it can deliver relatively soon. The rest is future build. TerraPower's Natrium units are 345 megawatts each and, per the agreement, would not start supplying power until at least 2032, with the additional units targeted for 2035.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source Oklo's Pike County campus is targeted for as early as 2030.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source None of the new reactors exists yet, and the agreements themselves grew out of a Meta request for proposals in December 2024 seeking 1 to 4 gigawatts of new nuclear starting in the early 2030s.3 ANS Nuclear Newswire 2026-01-12 The agreements stem from Meta December 2024 RFP seeking 1 to 4 GW of new nuclear starting in the early 2030s, with TerraPower Natrium units at 345 MW each and Oklo Aurora units targeted online as early as 2030 into the PJM market. Open source

So the honest decomposition is a couple of gigawatts of near-term contracted output from existing plants, wrapped around several gigawatts of first-of-a-kind advanced reactors that must be financed, licensed, and built over the next decade. The 6.6 gigawatt figure is a 2035 ceiling, not a 2026 supply.

The real story: compute is now an energy problem

The reason a company like Meta is signing multi-gigawatt nuclear deals at all is that the binding constraint on AI compute has shifted from chips to power. Meta is committing capital now, years before the electrons arrive, because securing firm carbon-free baseload for a supercluster is a lead-time problem measured in the same horizon as reactor construction.1 Utility Dive 2026-01-09 Meta announced deals on January 9, 2026 to secure up to 6.6 GW of nuclear power by 2035 across Oklo, Vistra, and TerraPower for its Prometheus supercluster in New Albany, Ohio, following a June 2025 Constellation agreement, with power in the PJM region. Open source We assess, with high confidence, that the structure of these deals, existing-plant PPAs for the near term and funded new build for the 2030s, is exactly what a buyer does when it needs guaranteed power on a schedule longer than any single data center's planning cycle. The compute buildout is being underwritten by energy contracts first.

Who gains and who loses

The nuclear developers gain the most concrete benefit. TerraPower and Oklo receive a creditworthy anchor customer and, in TerraPower's case, direct funding to develop units, which de-risks first-of-a-kind projects that struggle to reach financial close without a buyer.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source Vistra gains long-dated revenue on plants it already runs, plus uprate economics.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source Meta gains a claim on firm carbon-free power and the public narrative of powering American AI leadership responsibly.1 Utility Dive 2026-01-09 Meta announced deals on January 9, 2026 to secure up to 6.6 GW of nuclear power by 2035 across Oklo, Vistra, and TerraPower for its Prometheus supercluster in New Albany, Ohio, following a June 2025 Constellation agreement, with power in the PJM region. Open source

The party that carries the risk is Meta's own capital, and secondarily the grid. Funding two Natrium units and committing to more concentrates exposure to advanced-reactor projects that have not been built at scale, and if they slip past 2032, the supercluster's power plan slips with them.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source The near-term pressure lands on the PJM grid and on ratepayers in Ohio and Pennsylvania, where a hyperscaler contracting existing baseload and adding load can tighten regional supply before the new reactors arrive.1 Utility Dive 2026-01-09 Meta announced deals on January 9, 2026 to secure up to 6.6 GW of nuclear power by 2035 across Oklo, Vistra, and TerraPower for its Prometheus supercluster in New Albany, Ohio, following a June 2025 Constellation agreement, with power in the PJM region.

The counter-case

The case that this is more real than a stack of 2030s promises rests on the Vistra piece and the funding structure. More than 2 gigawatts of 20-year PPAs on operating reactors is firm supply, not aspiration, and TerraPower receiving development funding rather than a bare offtake letter is a stronger commitment than most corporate nuclear announcements.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source If the advanced reactors hit their 2030 to 2032 targets, the 6.6 gigawatt figure converts from ceiling to delivery on a schedule that matches Meta's buildout. For the skeptical read to be wrong, first-of-a-kind Natrium and Aurora units would need to reach commercial operation roughly on time, which the industry has rarely achieved. That is the load-bearing uncertainty.

What to watch

  • Vistra output begins on schedule. If the contracted existing-plant power and Ohio uprates start delivering to Meta on the stated timeline, the near-term piece is firm; delay would signal even the operating-plant portion is softer than announced.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source
  • TerraPower reaches construction on the first Natrium unit. If the two funded units break ground and hold a 2032 target, the new-build bet is tracking; slippage past 2033 would push the supercluster's firm power into the back half of the decade.2 World Nuclear News 2026-01-09 Vistra agreed to more than 2.1 GW via 20-year purchase agreements at Beaver Valley, Perry, and Davis-Besse plus uprates; TerraPower will fund two 345 MW Natrium units with rights to six more starting around 2032; Oklo plans a 1.2 GW Pike County campus online as early as 2030. Open source
  • Oklo energizes the Pike County campus by 2030. A first phase online near 2030 would validate the advanced-reactor timeline; a multi-year slip would confirm the 6.6 gigawatt number is a distant ceiling.1 Utility Dive 2026-01-09 Meta announced deals on January 9, 2026 to secure up to 6.6 GW of nuclear power by 2035 across Oklo, Vistra, and TerraPower for its Prometheus supercluster in New Albany, Ohio, following a June 2025 Constellation agreement, with power in the PJM region. Open source
  • Grid and ratepayer friction surfaces in PJM. If Ohio or Pennsylvania regulators flag capacity or rate pressure from the added data center load before new reactors arrive, the near-term cost of the buildout is landing on the grid.3 ANS Nuclear Newswire 2026-01-12 The agreements stem from Meta December 2024 RFP seeking 1 to 4 GW of new nuclear starting in the early 2030s, with TerraPower Natrium units at 345 MW each and Oklo Aurora units targeted online as early as 2030 into the PJM market. Open source The signal to track is not the gigawatt headline, it is whether a single reactor gets built on time.
