This paper presents an assessment of the utilization potential of biomass residues for grid-connected power generation in Thailand, including the spatial distribution and seasonal variation of biomass residues and energy potential. The levelized costs of electricity (LCOE) in various scenarios were also estimated. The residues of up to 17 studied crops were selected depending on the regions. ArcGIS was used as the tool for assessing and mapping the biomass potential. The potential of grid-connected power generation was assessed based on a biomass-fired power plant, the seasonal availability of crop residues by region, and the location of the electrical substations. Based on a 50% of collection factor (base case), the total energy potential of the available biomass residues was 11,299 ktoe year⁻¹, which can generate 5019 MW (30,491 GWh year⁻¹) of power and had LCOEs for power plant capacities of 5 to 9 MW in the range of US$77.72 to 87.66 MWh⁻¹. The results also show that 17.3 MtCO₂ year⁻¹ of GHG emissions could be avoided with the abatement cost ranging from −US$89.36 to − 115.83 tCO₂⁻¹. According to Thailand’s PDP2018, the estimated electricity generation potential was approximately 8.3% of forecasted electricity demand in 2037. The improvement of the collection factor by up to 75%, the power generated, and the GHG emissions avoided were about 1.5 times higher than the base case. These findings are useful for the management, promotion, and zoning of biomass utilization for power generation.

本文对泰国并网发电中生物质残渣的利用潜力进行了评估，包括生物质残渣的空间分布和季节变化以及能源潜力。还估算了各种情况下的平均电力成本（LCOE）。根据地区选择了多达17种研究作物的残留物。ArcGIS被用作评估和绘制生物量潜力的工具。并网发电的潜力是根据生物质燃料发电厂，按地区划分的农作物残茬的季节性供应量以及变电站的位置进行评估的。基于50％的收集因子（基本情况），可用生物质残渣的总能量潜力为11,299 ktoe年^-1，可产生5019兆瓦（30,491 GWh年^-1）的电力，并且具有5至9 MW电厂容量的LCOE在77.72至87.66 MWh ^-1之间。结果还表明，减排成本从−89.36美元至− 115.83 tCO ₂ ^-1可以避免17.3 MtCO ₂ 年^-1的温室气体排放。。根据泰国的PDP2018，估计的发电潜力约为2037年预测的电力需求的8.3％。收集系数的提高高达75％，发电量和避免的GHG排放量比基准提高了约1.5倍案件。这些发现对于发电的生物质利用的管理，推广和分区很有用。
