초록
This study is about comparing coal thermal plant to LNG combined power plant in respect ofenvironmental and economic cost analysis. In addition sensitive analysis of power cost anddiscount rate is conducted to compare the result of change in endogenous and exogenousvariable. For environmental assessment, when they generate 10,669GWh yearly, coal thermalpower plant emits sulfur oxides 959ton, nitrogen oxide 690ton, particulate matter 168ton andLNG combined power plant emits only nitrogen oxide 886ton respectively every year. Regarding economic cost analysis on both power plants during persisting period 30 years, coalthermal power plant is more cost effective 4,751 billion won than LNG combined taking inaccount the initial, operational, energy and environmental cost at 10,669GWh yearly in spiteof only LNG combined power plant’s energy cost higher than coal thermal. In case ofsensitive analysis of power cost and discount rate, as 1% rise or drop in power cost, the totalcost of coal thermal power plant increases or decreases 81 billion won and LNG combined157 billion won up or down respectively. When discount rate 1% higher, the cost of coalthermal and LNG combined power plant decrease 498 billion won and 539 billion won foreach. When discount rate 1% lower, the cost of both power plant increase 539 billion wonand 837 billion won. With comparing each result of change in power cost and discount rate,as discount rate is weigher than power cost, which means most influential variable of powerplan is discount rate one of exogenous variables not endogenous.
