Description
This dataset represents the average power generation situation of reservoir-dam-type hydropower stations in China. The data are obtained by weighted aggregation of the production datasets of multiple provinces (regions, municipalities) such as Hebei, Zhejiang, Anhui, Henan, Shanxi, Jilin and Fujian. A reservoir-dam-type hydropower station has one reservoir to provide a regulating and storage function. For the production dataset of a specific technology, the greenhouse gas (mainly CO2 and CH4) emissions over the reservoir life cycle are estimated based on the Tier 1 method of the National Greenhouse Gas Inventory Guidelines (2019 Refinement), with emission factors adjusted according to the local climate zone and reservoir age. The hydropower station parameters are set according to design specification standards, i.e. 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. The data are mainly derived from official statistics.
Activity Description
The system boundary covers the entire operation and maintenance stage of reservoir-based hydropower plants, including initial reservoir filling, releasing water to drive the turbines and generate electricity, and routine equipment maintenance.
Process Description
The product is grid-connected power in kWh, with a voltage level of ≥35 kV.

Technology comment
A storage dam-type hydropower station has a reservoir to regulate storage. The storage dam-type hydropower station here considers combinations of different installed capacity sizes. Hydropower station parameters are set according to design specifications and standards, that is, the technical service life of small hydropower station projects is 30 years, the technical service life of medium-sized hydropower station projects is 50 years, and the technical service life of large hydropower station projects is 100 years.
