If a company got approval before March 13, 2020, to build a hydropower project (a facility that generates electricity from flowing water, usually at a dam) but hasn't started construction yet, this gives them a lot more time to get going. The federal agency that oversees these energy projects can now grant up to six extra years beyond the extension already allowed under existing rules, given out in chunks of two years at a time. It also lets that agency restore a project's license even if it already expired, as long as it qualifies for this extended deadline, treating it as if the license had stayed active the whole time.
