Smith Mountain Pumped Storage Project

Technology Type Open-loop Pumped Hydro Storage
Rated Power 560000 kW
URL More about Smith Mountain Pumped Storage Project
Smith Mountain Dam houses five hydroelectric generators with a combined installed capacity of 560 MW. Smith Mountain Lake Dam utilizes pumped-storage hydroelectricity by which water that is released downstream can be pumped back into Smith Mountain Lake for re-use. The Leesville Dam regulates the Smith Mountain Lake's outflows and stores water to be pumped back into the Smith Mountain Lake for this purpose. Hydro-electricity is usually produced during high-demand times (day) and pumped back into the lake during low demand times (night). The Leesville Dam also produces hydro-electricity as well. In December, 2009, The U.S. Federal Energy Regulatory Commission granted Appalachian Power a new license to operate the hydro-electricity plant. The new 30-year license replaces the original 50-year license and also addresses recreational and environmental management.
