Description
This dataset represents electricity generation from medium-scale (>=50, <300 MW) pumped storage hydropower plants in Jiangsu, China. The average technology is characterized based on two operating medium-scale pumped storage units, with a total installed capacity of 100 MW. The technical service life of hydropower plants is assumed to be 50 years. Key data are primarily derived from official statistics.
Activity Description
The scope of activities for the production of this product covers the entire operational and maintenance phase of a pumped-storage Hydropower plant, including pumping water from the lower reservoir to the upper reservoir, releasing water from the upper reservoir to drive turbines for electricity generation, and routine equipment maintenance.
Process Description
The product is grid-connected electricity measured in kWh, with a voltage level ≥ 35 kV.

Technology comment
The pumped-storage hydropower plant uses electricity during periods of low grid demand to pump water from a lower reservoir to an upper reservoir for energy storage. During peak grid demand, the stored water is released back to the lower reservoir to generate electricity. The main difference between pumped-storage hydropower plants and conventional dam-type Hydropower plants lies in the number of reservoirs. Here, medium-scale pumped-storage Hydropower plants refer to facilities with an installed capacity of >50~<300 MW. Hydropower plant parameters are set according to design standards: small-scale hydropower projects have a technical service life of 30 years, medium-scale projects 50 years, and large-scale projects 100 years.
