Oklo’s 750-MW advanced nuclear project removed from PJM study, spurring FERC intervention

Oklo says PJM Interconnection improperly dropped its 750-MW mixed-technology project from the grid operator’s interconnection study, delaying development by at least 14 months and increasing costs; it filed an emergency complaint with FERC on Aug. 28, 2026, asking that PJM reinstate the project in the current cycle and seek waivers to prevent study delays. PJM plans to respond, while Oklo notes the project combines synchronous units (gas and advanced nuclear) with inverter-based units (fuel cells) and is tied to Meta data centers in Ohio. The dispute arises as PJM reformulates its interconnection queue and tallies hundreds of GW of capacity in the first cycle of the reformed process.
