Biopower could replace traditional diesel-based electricity as a cheaper and carbon-friendly alternative in NE Colombia. Using regional yield and cost data, we analyzed the feasibility of wood-based electricity production from nine clones of eucalyptus and compared it to electricity derived from diesel in the Orinoquia region of Colombia. With our suggested silvicultural prescription, electricity from all the clones was less carbon-intensive than diesel-based electricity by at least 81%, and up to 87%, across selected clones. The unit cost of wood-based electricity was lower than diesel ($280 MWh⁻¹). Clone 5 was the cheapest ($92 MWh⁻¹) and least carbon-intensive (96 kg CO₂e MWh⁻¹) feedstock for electricity while the Control Clone was the most expensive ($104 MWh⁻¹) and most carbon-intensive (139 kg CO₂e MWh⁻¹). Approximately 5000 hectares of land will be annually required to ensure sustainable biopower supply for a 10 MW power plant. Specific densities and calorific values of these clones played an essential role in determining the carbon intensity and the cost of generated electricity. Biopower could be promoted in the Orinoquia region with no further economic incentive. Our study will help support the bioeconomy in Colombia, which is exploring ways for boosting rural economies after the conclusion of the Peace Process.

在哥伦比亚东北部地区，生物能发电可以取代传统的柴油发电，成为一种更便宜，更环保的替代能源。利用区域产量和成本数据，我们分析了从9个桉树无性系生产木质电力的可行性，并将其与哥伦比亚Orinoquia地区的柴油发电相比较。根据我们建议的造林处方，在所有选定的克隆中，来自所有克隆的电力比基于柴油的电力的碳强度低至少81％，最高可达87％。木质电力的单位成本低于柴油（280 MWh ^-1）。克隆5最便宜（$ 92 MWh ^-1）和碳排放最少（96 kg CO ₂ e MWh ^-1），而控制克隆成本最高（$ 104 MWh ^-1），碳排放量最高（139 kg CO ₂ e MWh ^-1）。每年将需要约5000公顷土地，以确保10兆瓦发电厂的可持续生物发电供应。这些克隆的比密度和热值在确定碳强度和发电成本中起着至关重要的作用。在没有进一步经济刺激的情况下，可以在奥里诺基亚地区促进生物发电。我们的研究将有助于支持哥伦比亚的生物经济，该经济正在探索和平进程结束后促进农村经济发展的方法。
