Advanced nuclear developer Oklo filed an emergency complaint at the Federal Energy Regulatory Commission on August 28, 2026, asking regulators to order the PJM Interconnection to return a 750 MW generating project to its ongoing interconnection study cycle. Oklo said PJM improperly removed the project, a decision the company estimates will push the schedule back by at least 14 months and raise development costs.
The project combines three generation types in one campus: 150 MW of advanced nuclear capacity, 300 MW of fuel cells, and 300 MW of gas-fired generation. Oklo argued in its partially redacted filing that PJM interconnection rules were written around single-technology projects and fall short when applied to a multifuel design of this kind.
Oklo left the project unnamed in the filing. The company has announced plans for a 1.2 GW power campus in Pike County, Ohio, which sits inside the PJM footprint, with Meta backing that site under a January agreement to supply electricity to its data centers. Oklo designs reactors in the 15 MW to 75 MW range and describes the project as carrying critical national importance.
The dispute arrives while PJM works through a heavy backlog of interconnection requests driven by data center growth and new generation proposals across its 13-state territory. FERC has set no ruling schedule on the complaint.
Interconnection timing now shapes the economics of advanced nuclear projects, since financing commitments and customer contracts frequently hinge on a firm grid connection date.
