Wind energy is one of the most cost-effective forms of renewable energy source with significant increment in yearly installed capacities all around the world. In this study, three commercial wind turbines, namely POLARIS P15-50, POLARIS P50-500 and VESTAS V110-2.0, were chosen as large-scale wind energy conversion systems (WECSs) for technical assessment of electric power generation in eight selected locations spreading across the Tigray region of Ethiopia. The economic evaluations of these three WECSs for electric power generation in the selected locations were estimated using present value of cost (PVC) method. These results showed that the highest capacity factor is obtained as 7.873 % using VESTAS V110-2.0 at Mekele, while the lowest as 0.002 % using POLARIS P15-50 at Shire. Average minimum cost per kWh obtained at Mekele was 0.0011$/kWh using VESTAS V110-2.0, while the highest average cost was 7.3148$/kWh using POLARIS P15-50 at Shire. Furthermore, it can be suggested that Atsbi, Chercher, Mekele and Senkata were most profitable for electrical and mechanical applications than hydropower cost in the country.

提格里地区（埃塞俄比亚）的八个选定地点的风能潜力和用于发电的风能转换系统（WECS）的成本估算

风能是可再生能源中最具成本效益的形式之一，在世界范围内，其年装机容量已大大增加。在这项研究中，选择了三台商用风力涡轮机，即POLARIS P15-50，POLARIS P50-500和VESTAS V110-2.0，作为大规模风能转换系统（WECS），用于在选定的八个位置扩展发电技术穿越埃塞俄比亚的提格里地区。使用成本现值（PVC）方法估算了这三个WECS在选定位置发电的经济评估。这些结果表明，使用Mekele的VESTAS V110-2.0可获得最高的容量因子，为7.873％，而使用Shire的POLARIS P15-50可获得的最低容量因子为0.002％。在Mekele获得的每千瓦时平均最低成本为0。使用Shire的VESTAS V110-2.0为0011美元/千瓦时，而使用POLARIS P15-50的最高平均成本为7.3148美元/千瓦时。此外，可以认为，与该国的水电成本相比，阿特斯比，切尔歇尔，梅凯尔和森卡塔在电气和机械应用方面的利润最高。
