What does this do?
The FLOWS Act removes the federal approval requirement for routine maintenance, small repairs, and minor changes at existing licensed hydropower facilities. It also allows operators to make temporary operational adjustments during emergencies such as floods or droughts without prior sign-off from FERC, while keeping FERC's safety oversight in place. A new streamlined licensing path is created for micro hydrokinetic projects of 5 megawatts or less, with FERC required to decide on applications within one year using simplified environmental reviews.
Who does it affect?
The bill directly affects companies and individuals who operate existing licensed hydropower dams and facilities, as well as developers seeking to build small water-current or tidal energy systems. Communities located near rivers, coastlines, or waterways where micro hydrokinetic projects might be built could also be affected.
Why does it matter?
FERC must report to Congress within five years on how the new small-project licenses affect the environment, local economies, and electricity costs, creating a mechanism for evaluating real-world outcomes. The faster permitting timeline and reduced review requirements for small projects could change the pace and volume of new water-based energy development.
