Pollutants emission from the thermal pwer plants has already become one of the main environmental problems. At present

although the pollution charge system according to total pollutant emission is applied in China

but it hasn’t effectively promoted pollutant emission from thermal power plants to be decreased due to the high cost of administrative management

low charge standard

and high total pollution charge. In order to exert the promotion effect of economic means to pollutants mitigation

a new pollution charge system for thermal power plants has been put forward

and related mathematic model being established

and a new pollution charge standard being worked out. In the new system

the integrated pollution charge is applied to SO2 and NOx emission

while charge on total emission being applied to CO and total suspended particles (TSP) or soot. Results of analysis from examples show that the new system can make use of power market’s self-regulating mechanism to effectively promote the pollutants reduction of thermal power plants

That is to say

through suitable pollutants mitigation measures

the thermal power plant can greatly reduce the expenditure of pollution charge

enhancing its own competitive strength in the market.
