Effectively enhancimg the efficiency of power plants can help reduce both the cost of power generation and the greenhouse gas emissions. In this research we collect and analyze the operational data of coal-fired steam turbine power units No.1~No.8 of Taichung Power Plant, in order to establish a multiple regression model of thermal efficiency. This research provides suggestions for Taipower company to improve its thermal efficiency. Our major empirical findings are: (1) The temperature of main steam, re-heat steam pressure drop and pressure of main steam significantly increase the thermal efficiency. (2) The temperature of the air inlet, temparture of the water inlet, in-plant electricity usage, re-heat steam temperature and exhaust pressure significantly worsen the thermal efficiency. Therefore, the Taipower caompany should select appropriate locations of fire-power plants, keep lodaings at the rated levels, reduce generation-irrelevant in-plant electricity usage, promote trainings of operating personnel, and improve the functions of boliers, etc., in order to enhance its thermal efficiency.
