Abstract
At present, ESCO (Energy Saving Company) service are mostly supplied to office and commerial sectors while they are recognized as effective ways to reduce carbon dioxide and energy costs against global warming. In this research, an analysis was made to clarify the effect of ESCO services for a waste incineration plant on environmental and business performance. The results reveal that: inverter control for plant facilities and gas co-generation give great contribution on reducing carbon dioxide and energy cost; changing gas prices and selling prices of electric power based on the Law for Renewable Portfolio Standard have an obvious influence on payout period of the co-generation plant.
