ARC Act of 2026
The ARC Act of 2026 establishes a $3.6 billion federal program to provide cost certainty for advanced nuclear energy projects seeking loan guarantees under the Energy Policy Act of 2005. It requires qualifying projects to submit detailed cost estimates, schedule risk analyses, and a project delivery plan to demonstrate on-time, on-budget construction. Borrowers cover cost overruns up to 120% of the base cost estimate, after which the program covers up to 30% of that base estimate (capped at $1.2 billion per project). This directly affects advanced nuclear reactor developers and project owners seeking federal loan guarantees, with strict oversight requirements including quarterly progress reviews and annual schedule updates.
