Other DOE Funding Opportunities

For other DOE funding and technical assistance opportunities that may be relevant for water power technologies, WPTO recommends looking into the following offices: 

Advanced Research Projects Agency-Energy (ARPA-E): ARPA-E advances high-potential, high-impact energy technologies that are too early for private-sector investment. ARPA-E issues periodic funding opportunities focused on overcoming technical barriers around a specific energy area as well as open topics to identify high-potential projects that address the full range of energy-related technologies.  

Grid Deployment Office (GDO): GDO works to provide electricity to everyone, everywhere, by investing in critical energy sources—like hydropower—to bolster and improve the energy grid. GDO manages DOE’s three hydroelectric incentive programs

Loan Programs Office (LPO): LPO offers four distinct loan programs to finance a wide array of energy infrastructure projects across the country. Water power projects may be eligible for DOE loan guarantees, especially under the Innovative Clean Energy Loan Guarantee Program or the Tribal Energy Loan Guarantee Program. 

Office of Clean Energy Demonstrations (OCED): OCED is a multi-technology office with funding for demonstration programs that could support hydropower or marine energy technologies. OCED partners with private sector entities to accelerate market adoption of clean energy technologies, including long-duration storage technologies such as pumped storage hydropower.  

Office of Cybersecurity, Energy Security, and Emergency Response (CESER): CESAR supports development and deployment of advanced cyber applications, technologies, and threat collaboration efforts with the U.S. energy sector. 

Office of Manufacturing and Energy Supply Chains (MESC): MESC works to strengthen manufacturing and energy supply chains needed to modernize the nation’s energy infrastructure.
