Oklo Sinks 5% as PJM Pulls Its Meta-Backed Ohio Project, NuScale Power Barely Budges

Shares of nuclear developer Oklo fell 5% after grid operator PJM Interconnection removed a 750-megawatt generating project backed by Meta Platforms from its interconnection study cycle. The planned project in Pike County, Ohio, intended to power Meta data centers, forms part of a larger 1.2-gigawatt campus combining advanced nuclear, fuel cells, and gas generation. PJM cited voltage ride-through deficiencies for the withdrawal, triggering an emergency Federal Energy Regulatory Commission (FERC) complaint from Oklo seeking queue restoration. The removal introduces a potential delay of at least 14 months and threatens to escalate project development costs, posing execution headwinds for Meta's clean power procurement strategy. Compounding the issue, broader nuclear equities faced downward pressure as the 10-year Treasury note yield rose to 4.786%, punishing long-duration, pre-revenue power assets. The development highlights grid interconnection as a primary operational risk factor for hyperscale tech companies securing dedicated nuclear energy infrastructure.
