A federal regulatory body has approved a waiver allowing NextEra Energy to potentially revive the Duane Arnold nuclear plant in Iowa by 2029, with the estimated cost of recommissioning projected to be between $50 and $100 million. The decision comes as escalating electricity needs, particularly from expanding data center operations, drive demand for increased power capacity, and is facilitated by the utilization of existing solar infrastructure on the site, previously established just late in 2024.
