The mechanism: The federal government has spent the last year systematically removing the two biggest bottlenecks to AI data center buildout — grid interconnection queues and generation siting. DOE has issued requests for proposals to co-locate AI data centers with nuclear and gas generation directly on federal land at Idaho National Laboratory, Oak Ridge, Savannah River, and Paducah. Separately, FERC ordered PJM — the nation's largest grid operator — to build formal "colocation" transmission tariffs that let data centers sit behind the meter next to gas and nuclear plants, bypassing years-long interconnection queues. Layer in the White House's May 2025 nuclear executive orders, which pushed DOE to fast-track advanced reactor licensing (a third reactor hit criticality by the administration's self-imposed July 4, 2026 deadline), and the policy machinery for siting power at the compute, not miles away from it, is now operating on all cylinders. That doesn't eliminate the engineering problem — it relocates it. Every behind-the-meter gas turbine or microreactor still needs switchgear to step down and route the power, and every megawatt landing in a rack still needs to be cooled. That's where Eaton and Vertiv split.

Who cashes in:

  • Eaton (ETN) is the direct beneficiary of generation-siting policy. Behind-the-meter gas and nuclear plants don't eliminate the need for medium-voltage switchgear, transformers, and power distribution — they just move the interconnection point onto the data center campus itself, and someone still has to build the electrical plant that ties turbine to rack. Eaton's Electrical Americas segment has posted data center order growth far outpacing its already-hot core backlog, and the company is sinking over a billion dollars of incremental capex into new transformer and switchgear capacity, including a new large power transformer plant, specifically to work through multi-year lead times. FERC's PJM colocation order is a tailwind, not a threat — it just changes where the switchgear gets installed.
  • Vertiv (VRT) wins on the other side of the same coin: thermal. Gas and nuclear behind-the-meter siting is being paired with ever-denser AI racks, and denser racks mean liquid cooling isn't optional. Vertiv has been acquiring its way deeper into the thermal chain (recent deals in liquid-cooling components and heat-exchange technology) precisely because DOE-blessed co-location sites are being built around next-generation, high-density GPU clusters from day one — no legacy air-cooled retrofit baggage.
  • Nvidia (NVDA) and Broadcom (AVGO) benefit indirectly: DOE-approved power capacity is the gating factor on how many accelerators can actually be racked and sold, and every gigawatt unlocked behind the meter is compute that no longer waits on a utility interconnection queue.
