Water Power Research and Development Reauthorization Act

S 3684 reauthorizes and expands U.S. government funding for water power research, specifically targeting hydropower and marine energy technologies. It increases annual funding to $300 million (2026-2030), with $200 million for marine energy and $100 million for hydropower, focusing on new research areas like arctic marine systems, invasive species mitigation, and grid integration. Key provisions include streamlining hydropower licensing studies, advancing manufacturing of marine energy components through university-industry partnerships, and requiring workforce development programs for Tribal communities and educational institutions. The bill mandates annual congressional briefings on research progress and incorporates cybersecurity into hydropower infrastructure studies. It directly affects federal agencies, research institutions, Tribal entities, and the marine energy industry through expanded funding and new research priorities.
