Regulators have delivered successive blows to Amazon and Meta's nuclear power ambitions for their data centers.
Regulatory hurdles, such as sighting of a rare bee species and concerns over lower reliability and higher costs, have hindered the plans.
The Federal Energy Regulatory Commission (FERC) denied Amazon's expansion of a data center power agreement to connect directly to a nuclear power plant.
FERC has several more large co-location requests from data centers to review in the future.
