Reliable records of monthly hydropower generation are essential for analyzing seasonal patterns in power supply and planning for long-term energy resilience. In U.S. hydropower plants, however, these monthly values have historically been imprecisely estimated or else altogether unavailable. This data gap has limited the accuracy of studies exploring interrelated outcomes such as hydropower reliability, drought […]

Hydropower continues to play a critical role in supporting the U.S. electric grid, providing nearly 6% of utility-scale generation and the vast majority of long-duration energy storage.
