南亚区域合作联盟（SAARC）的发展中地区生活着大量生活在贫困线以下的人。未来，在该地区提供价格合理、普遍可及、可靠、低碳至零碳的电力将是主要目标。在每小时解决的基础上，模拟了SAARC在2030年成本最优的100%可再生能源系统。该区域被划分为16个子区域，并根据高压直流（HVDC）电网连接水平设置了三种不同的场景。获得的总系统平准化电力成本（LCOE）的结果显示，从分散的71.6欧元/兆瓦时下降到集中式电网连接场景的67.2欧元/兆瓦时。模拟了工业气体生产与海水反渗透淡化需求相结合的附加情景，结果表明系统成本降低5%，总发电量降低1%。结果表明，根据本研究中使用的成本假设，100%可再生能源系统在南盟地区可能是现实的，并且它可能比核能和化石碳捕获和储存（CCS）替代品更具成本竞争力。本研究的局限性之一是安装可再生能源的土地成本不包括在LCOE计算中，但被认为是一个很小的贡献。
The developing region of SAARC (South Asian Association for Regional Cooperation) is home to a large number of people living below the poverty line. In future, providing affordable, universally accessible, reliable, low to zero carbon electricity in this region will be the main aim. A cost optimal 100% renewable energy system is simulated for SAARC for the year 2030 on an hourly resolved basis. The region was divided into 16 sub-regions and three different scenarios were set up based on the level of high voltage direct current (HVDC) grid connections. The results obtained for a total system levelised cost of electricity (LCOE) showed a decrease from 71.6 €/MWh in a decentralized to 67.2 €/MWh for a centralized grid connected scenario. An additional scenario was simulated to show the benefits of integrating industrial gas production and seawater reverse osmosis desalination demand, and showed the system cost decreased by 5% and total electricity generation decreased by 1%. The results show that a 100% renewable energy system could be a reality in the SAARC region with the cost assumptions used in this research and it may be more cost competitive than nuclear and fossil carbon capture and storage (CCS) alternatives. One of the limitations of this study is the cost of land for installation of renewables which is not included in the LCOE calculations, but regarded as a minor contribution.
