Included activities starts

This activity starts with the pumping of water from the lower reservoir to the upper reservoir in a constructed hydropower station, in preparation for power generation

Included activities ends

The boundary of production activities ends with the production of 1 kWh of net electricity delivered to the point of interconnection for grid connection.

Description

This dataset represents the power generation of an average pumped storage hydropower plant in in 2021. pumped storage hydropower plant units with a total installed capacity of MW were considered. The annual power generation was billion kWh. Data are mainly from official statistics.

Activity Description

The process covers the entire stage of operation and maintenance of pumped storage power station, including activities of pumping water from the lower reservoir to the upper reservoir, releasing water from the upper reservoir to drive the turbines for power generation, daily maintenance of equipment, etc.

Process Description

The product is electricity measured in kWh, covering voltage levels of ≥35 kV.

Technology comment

A pumped-storage hydropower station uses electrical power from the grid during off-peak hours to pump water from a lower reservoir to an upper reservoir for storage, and then releases the water back to the lower reservoir to generate electricity during peak hours. The main difference between this type of station and a conventional dam-type hydropower station lies in the number of reservoirs. This description of pumped-storage hydropower stations takes into account combinations with different installed capacity scales. Hydropower station parameters are set according to design standards, meaning the technical service life of a small hydropower station project is 30 years, a medium hydropower station project is 50 years, and a large hydropower station project is 100 years.
