Water Power Technologies Office. It is a division within the Office of Energy Efficiency and Renewable Energy at the United States Department of Energy. The office is dedicated to advancing research, development, and commercialization of innovative technologies for clean, domestic power generation from water resources. Its work focuses on harnessing energy from rivers, tides, ocean waves, and ocean currents to support a resilient United States electrical grid and contribute to national energy security goals.

Mission and goals

The core mission is to accelerate the development and deployment of cost-competitive hydropower and marine energy technologies across the United States. A primary goal is to enhance the flexibility and reliability of the nation's power system by leveraging the unique attributes of water power. This includes supporting the modernization of the existing hydropower fleet and fostering new markets for marine and hydrokinetic energy. The office aims to achieve these objectives through strategic partnerships with national laboratories, universities, and private industry to drive technological innovation and reduce market barriers.

Research and development programs

The office administers a comprehensive portfolio of research and development programs spanning multiple technology areas. Key initiatives include the Hydropower Program, which focuses on improving the efficiency and environmental performance of conventional hydropower plants. Concurrently, the Marine Energy Program supports the advancement of technologies that capture energy from ocean waves, tidal currents, and ocean thermal energy conversion. These programs fund critical work at institutions like the National Renewable Energy Laboratory and Pacific Northwest National Laboratory, addressing challenges from early-stage concept validation to prototype testing in real-world environments like the Pacific Marine Energy Center.

Key technologies and projects

Significant technologies under development include advanced turbine designs for low-head hydropower and novel power take-off systems for wave energy converters. The office has supported landmark projects such as the deployment of the Ocean Energy Turbine by Ocean Renewable Power Company in Maine and testing at the Wave Energy Test Site in Oregon. It also champions the modernization of the existing hydropower infrastructure through initiatives like the HydroWIRES Initiative, which explores how hydropower can provide essential grid services. Research into environmental mitigation technologies, such as fish-friendly turbines, is a critical component of its project portfolio.

History and legislative background

The office was formally established in 2008 under the purview of the Energy Independence and Security Act of 2007, which emphasized the need for increased marine energy research. Its formation was further solidified by subsequent legislation, including the American Recovery and Reinvestment Act of 2009, which provided significant funding for water power projects. The Energy Policy Act of 2005 had earlier laid important groundwork by authorizing hydropower incentive programs. Over the years, congressional directives through various Appropriations bills have continued to shape its priorities and scope, linking its work directly to national goals for renewable energy and climate change mitigation.

Organizational structure and funding

The office is structured within the Office of Energy Efficiency and Renewable Energy and is led by a director who reports to the Assistant Secretary of Energy for Energy Efficiency and Renewable Energy. Its activities are carried out by a team of technical managers and specialists who oversee competitive funding opportunities and cooperative agreements. Primary funding is allocated through the annual United States Department of Energy budget, as determined by the United States Congress. The office also leverages funding and expertise through collaborations with other federal agencies like the Department of the Interior and the United States Army Corps of Engineers, as well as international partners.

Impact and achievements

The office's work has contributed to measurable advancements in the water power sector, including reductions in the cost of energy for emerging marine technologies and increased grid flexibility from hydropower. Its support has been instrumental in the first commercial tidal energy projects delivering power to the North American grid and in developing new tools for environmental monitoring. Achievements also include the creation of a robust domestic supply chain for water power components and the publication of influential resource assessments, such as the national hydropower resource assessment. These efforts collectively support the broader Biden administration goals for a carbon pollution-free electricity sector by 2035.
