This paper describes about life cycle evaluation of two kinds of power generation system which are using major resources of energy in Thailand between using natural gas and coal. Those power plants hold the share of Electricity Generating Authority of Thailand (EGAT) about 52.5% and 22.7% respectively classified by gross electricity production and by the type of fuel used in 2000. Therefore, it is necessary to understand the environmental influences from electricity production systems, in which could be instructed the component of environmental plan for reducing emissions and resources consumption. The aim of the study is to apply Life Cycle Assessment (LCA) with Numerical Eco-Load Total Standardization (NETS), which is used for evaluating the environmental burdens by identifying and quantifying energy and materials used and waste released to environment. And the Life Cycle Inventory (LCI) and Life Cycle Costing (LCC) of the power plant systems have been developed and estimated. As a result, the LCA-NETS point of view was discussed for further ecological power generating systems which will be acting more environmental friendly in the future.
