Description
This dataset represents the average power generation situation of conventional hydropower in Hainan region of China. Its data are obtained by weighted aggregation of the production datasets of local reservoir-dam type and run-of-river hydropower. For reservoir-dam type hydropower, hydropower stations can be classified by installed scale into small (<50 MW), medium (≥50, <300 MW) and large (≥ 300 MW) categories; limited by data availability, only the power generation data of the medium and large categories are included. The relevant parameters are set according to design specification standards, namely the technical service life of small hydropower projects is 30 years, that of medium hydropower projects is 50 years, and that of large hydropower projects is 100 years; their power generation data are collected in a bottom-up manner. For run-of-river hydropower, the power generation is estimated by deducting the power generation of pumped storage and reservoir-dam type hydropower stations from the total regional hydropower generation, and the design life of its average-scale stations is set at 50 years. The data are mainly sourced from official statistical data.

Technology comment
The power generation combination of storage dam-type and run-of-river hydropower stations was considered. For storage dam-type hydropower generation, hydropower stations can be divided into three categories according to installed capacity: small (<50 MW), medium (≥50, <300 MW), and large (≥300 MW). Due to data availability limitations, only the power generation data of medium-sized and large hydropower stations are included. The relevant parameters are set according to the design specifications and standards, i.e., the technical service life of small hydropower station projects is 30 years, that of medium-sized hydropower station projects is 50 years, and that of large hydropower station projects is 100 years. For run-of-river hydropower, the design life of an average-sized power station is set at 50 years.
