This paper presents the technical, financial, and environmental impact assessment of a 50-MW (MW) utility-scale wind farm in Ghana at four locations: Anloga, Atiteti, Sege, and Denu. The monthly average wind speeds recorded at the locations were 6.01 m/s, 5.98 m/s, 5.46 m/s, and 5.17 m/s respectively at 60 m above ground level. Capacity factors of 24.9%, 24.4%, 20.6%, and 18.0% were obtained at the locations respectively. The Net Present Value (NPV) was the main financial metric employed to determine the viability of the projects. The results indicated that a potential utility-scale wind project is viable at all locations under study. Furthermore, the Electricity Exported to the Grid and the Electricity Export Rate (EER) had the highest impact of 0.63 and 0.62 on the NPV respectively and therefore these key parameters should be well considered before any potential project implementation.
本文介绍了在加纳四个地点（安洛加、阿蒂泰蒂、塞盖和德努）建设一个50兆瓦公用事业规模风电场的技术、财务和环境影响评估。在地面60米高度处记录的这些地点的月平均风速分别为6.01米/秒、5.98米/秒、5.46米/秒和5.17米/秒。这些地点的容量系数分别为24.9%、24.4%、20.6%和18.0%。净现值（NPV）是用于确定项目可行性的主要财务指标。结果表明，在所研究的所有地点，一个潜在的公用事业规模风力发电项目都是可行的。此外，输送到电网的电量和电力出口率（EER）对净现值的影响最大，分别为0.63和0.62，因此在实施任何潜在项目之前，应充分考虑这些关键参数。
