Electricity production accounts for one of the largest water usages in the United States and worldwide. Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. Surface water was the source for more than 99 percent of total thermoelectric-power withdrawals according to USGS surveys. Forced evaporation (FE) in a receiving water body due to added heat from once-through cooling for thermal electric generating plants has been studied by Electric Power Research Institute and the USGS. However, these approaches are for screening level analyses and/or analytical solutions which do not address site specific FE.
