Recently, Low Carbon Society (LCS) principle has emerged as a practicable campaign for both developing and developed countries to deal with the dramatic increment of greenhouse gas concentration in the atmosphere. Various key features of LCS entail reducing energy demand and consumption while avoiding the fossil fuel utilization which is a major contributor to substantial CO 2 emissions. In this study, Thailand's power sector is modeled using Asia-Pacific Integrated Model (AIM/Enduse). The objective of this study is to model the Thai power sector such that the viability of clean generating technologies for Thailand is considered and their mitigating effects are analyzed. The results demonstrate that the fossil fuel based technology would be replaced by clean technologies including, coal-fired power plant with CCS technology and renewable energies in the LCS scenario. The LCS scenario can mitigate CO2 emissions by 58,098 ktCO2 in 2050 when compared to BAU scenario. © 2014 Published by Elsevier Ltd.
