恶滩水电站是南盘江、红水河上的第8个梯级,位于广西忻城县岩溶发育的峰丛谷地中低山区。坝址控制流域面积11.8万公里~2,多年平均流量2,060~3米/秒。电站地质为二迭系下统栖霞灰岩及上石炭统马平灰岩,构造比较简单;但多溶洞、漏斗和洼地。本电站是利用交通部门已建成的航运枢纽壅水发电,装置一台6万千瓦的机组,1981年4月25日开始试运行,5月中旬并网发电。至1981年年底止,已运行5,050小时,发电1.92亿度。
Ertan Hydropower Station is the 8th cascade on Nanpanjiang River and Hongshuihe, and is located in the middle and low mountainous areas of Feng Cong Valley where karst developed in Xincheng County, Guangxi. Dam site control basin area of 118,000 km ~ 2, the average annual flow of 2,060 ~ 3 m / s. The geology of the station is Qixia limestone and Upper Carboniferous Maping limestone of the Second Permian system. Its structure is relatively simple; however, there are many caves, funnels and depressions. The power plant is the use of transport sector has built a hydropower hub Shuishui power generation, installation of a 60,000-kilowatt unit, April 25, 1981 trial operation, mid-May and power generation. By the end of 1981, it had operated for 5,050 hours and generated 192 million kilowatts of electricity.
