Behind-the-meter means the data center co-locates at or directly interconnects with the plant, bypassing grid congestion entirely. The AI buildout needs always-on power that solar and wind cannot provide without storage that does not yet exist at scale. Nuclear is the only carbon-free source that runs at 90-plus percent capacity factor around the clock. Federal policy did not create that physics — it created the price signal and the regulatory framework that makes the economics close.
Who Cashes In
CEG (Constellation Energy) is the largest nuclear fleet operator in the U.S. with 21 reactors. It has already restructured its business around clean firm power offtake, and its scale means it can sign multi-gigawatt PPAs without stranding other load. The 45U credit flows directly to its generation margin.
TLN (Talen Energy) executed the template deal: a behind-the-meter data center campus at its Susquehanna nuclear plant in Pennsylvania, selling power directly to an Amazon Web Services co-location facility. That deal drew FERC scrutiny, which paradoxically confirms its commercial viability — regulators do not spend time on deals that do not matter.
CCJ (Cameco) mines and refines uranium. Every new long-term nuclear PPA signed by a U.S. operator requires a fuel supply contract. Higher contracted generation equals higher contracted uranium demand, and Cameco is the dominant Western supplier.
LEU (Centrus Energy) enriches uranium domestically. With DOE actively funding domestic enrichment capacity to reduce Russian fuel dependence, Centrus sits at the chokepoint between raw uranium and reactor-ready fuel — a position federal policy is explicitly trying to fortify.
Who Is Exposed
SMR (NuScale Power) and OKLO (Oklo) are the hardest hit by the current dynamic. Behind-the-meter deals are going to licensed, operating plants right now. Both companies are pre-revenue and years from commercial deployment. Capital markets rewarding operating nuclear assets are implicitly discounting the long runway these developers still face.
Natural gas peakers — represented in part by VST (Vistra), which operates a mixed nuclear and gas fleet — face the exposure on their gas-generation segment as nuclear PPAs displace the "always-on" premium that gas previously commanded for baseload reliability contracts.
What to Watch
The FERC ruling on co-location interconnection arrangements is the near-term binary. If FERC formalizes a framework that permits behind-the-meter nuclear offtake without full grid-service obligations, the CEG and TLN deal pipelines accelerate. Watch DOE loan guarantee announcements under the Title XVII program for the next reactor life-extension or co-location infrastructure project — that is the policy confirmation that moves the trade.
