This dataset represents the average power generation situation of run-of-river hydropower stations in China. Its data are obtained by weighted aggregation of the production datasets of Hebei, Liaoning, Jilin, Heilongjiang, Jiangsu, Zhejiang, Anhui, Fujian and other provinces (regions, municipalities). For the production datasets of specific regions, the power generation data are estimated by deducting the power generation of pumped storage and reservoir-dam type hydropower stations from the total local hydropower generation, and the average-scale hydropower station parameters are set at 50 years according to design specification standards. The data are mainly sourced from official statistical data.
