Amundsen John D. Keenan New York Institute of Technology, Old Westbury University of Pennsylvania, Philadelphia Thermal effluent from power plants can be used to provide warmth for fish, livestock, biomass crops, greenhouses, and wastewater treatment. In this research, the crucial question of choosing which of these technologies are best suited for any particular power plant is considered. The effects of several key factors were explored through sensitivity analyses, including reliability of the waste heat source, magnitude of the source, temperature of the source, the local climate and energy prices. For waste heat utilization from power plants to be economical, thermal effluent must be available at least 75 percent of the time at temperatures of 38°C (100°F) or higher. Significant economies of scale may be obtained when the generating station is 100 MW or larger, and waste treatment services are provided for at least 500 persons. M.
