Description
This dataset represents electricity generation from pumped storage hydropower plants in Liaoning, China. The average technology is characterized based on four operating pumped storage units, with a total installed capacity of 1200 MW and an annual electricity generation of 1.644 billion kWh, accounting for more than 99% of pumped storage electricity generation in the region. The 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 of ≥35 kV.

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. This study considers various combinations of installed capacities for pumped-storage hydropower plants. 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.
