WASHINGTON, August 30, 2017 - The Energy Department seeks projects adding hydroelectric power generating capabilities to existing dams and impoundments. It is estimated that adding hydropower to tens of thousands of existing dams could generate as much 12 gigawatts (GW) of grid electricity, enough to power over 8 million households. Hydroelectricity is already the nation’s top producer of renewable power, yielding 30 billion kilowatt-hours in March 2017. Using existing infrastructure such as dams would lower construction costs and reduce permitting time – in turn bringing power to the grid quicker. Applications are due by Sept. 6 for funding under section 242 of the Energy Policy Act of 2005.
