In addition to the Three Gorges and Gezhouba in the Yangtze River, large-scale hydropower projects in Yichang include Shuibuya, Geheyan and Gaobazhou in the Qingjiang River basin. Small hydropower is mainly distributed in the Xiangxi River basin, which originates in Shenlongjia and passes through Xingshan and Zigui, and in the Yuyang River basin in Wufeng. In terms of numbers, most of them are from Xingshan County, followed by Zigui Wufeng. Most of the hydropower projects in Xingshan County belong to the Xingfa Group, of which there are nearly 20.
