Author uses Turbine-Generator manufacturer's typical Heat Rate Curve, Condenser Design Condition and Heat Exchanger Institute Correction Factors for Water Temperature correction to Heat Transfer Coefficient, annual hourly distribution of wet bulb temperatures, and the effect of wet bulb on cooling tower cold water temperature to show the effect cold water temperature has on annual plant mega watt hour output of a Steam Turbine Electric Generating Station. Paper includes calculation procedures, tables and curves that should be developed, and sample energy value to obtain the capital worth of colder water.
