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.
