Impacts of biomass power generation and CO2 taxation on electricity generation expansion planning and environmental emissions

Thailand has a high potential to utilize renewable energy for electricity generation especially from agricultural waste; however, at present only a small fraction of biomass is used for energy purposes. This study aims to estimate the potential of biomass power generation and its impact on power generation expansion planning as well as mitigating carbon dioxide emission from the power sector. The harvest area and crop yield per area are taken into consideration to estimate the future biomass availability. The supplies of biomass are then applied as a constraint in the least cost electricity generation expansion-planning model. The cost of CO2 emissions is also added to the fuel costs as carbon taxation to make biomass power generation competitive to fossil fuels, then the optimum value of CO2 charge is found out. In addition, levels of CO2 limitation from power generation are also introduced to mitigate CO2 emissions.

An Assessment of Energy Efficiency Programs in Thai Commercial and Industrial Sectors

An assessment of benefits of the implementation of demand-side management (DSM) and energy efficiency programs to the commercial and industrial sectors in Thailand is presented, and the corresponding impacts on power-generation expansion planning and emissions are discussed. The reference building models were simulated to capture energy consumption patterns of the medium and large commercial buildings in Thailand. Nine subsectors in the industrial sector, classified according to the international standard codes, are modeled and analyzed through the technoeconomic approach. Scenarios of the energy efficiency programs in Thailand are applied to the commercial and industrial sectors to investigate the potential of energy savings. Control technologies of airborne emissions from the utilization of fossil fuels in the power sector are also applied. Finally, a least-cost electricity expansion model is used to generate new generation plans. Features of the resultant plans include a significant reduction in the required power capacity addition and airborne emissions of fossil-fired power plants compared to a reference plan.An assessment of benefits of the implementation of demand-side management (DSM) and energy efficiency programs to the commercial and industrial sectors in Thailand is presented, and the corresponding impacts on power-generation expansion planning and emissions are discussed.
