## Abstract

The Federal Energy Regulatory Commission (Commission) is revising its regulations to modify when the Commission will commence assessing annual charges to hydropower licensees and exemptees, other than state or municipal entities, with respect to licenses and exemptions authorizing unconstructed projects and new capacity. Specifically, the Commission will commence assessing annual charges on the date by which the licensee or exemptee is required to commence construction of an unconstructed project or new capacity, rather than on the date that project construction actually begins. The final rule provides administrative efficiency and promotes certainty among licensees, exemptees, and Commission staff as to when annual charges will commence.
