Description
This dataset represents the civil engineering construction and electromechanical equipment installation of a large-scale pumped-storage hydropower plant with an installed capacity of ~1400 MW. The technical service life of the Hydropower plants is assumed to be 100 years in accordance with design specifications. During the construction and installation stage, the main material inputs include cement, reinforcing steel, structural steel, fly ash, timber, and explosives, while energy inputs primarily consist of diesel fuel and electricity used for construction and installation activities. Land occupation associated with the hub project and reservoir inundation of the Hydropower plants is also considered. For the decommissioning and demolition stage, it is assumed that metallic materials, including reinforcing steel, steel, iron, aluminum, and copper, as well as wood, are recycled at a rate of 90%, while all remaining materials are disposed of via landfilling. The data are primarily derived from publicly available literature and empirical experience.
Activity Description
The process boundary involves raw material preparation, on-site construction, as well as demolition, recycling, and disposal phases, but does not include the operation and maintenance phase.
Process Description
The product is a pumped-storage Hydropower plant measured in units. A pumped-storage Hydropower plant utilizes electricity from the grid during off-peak load periods to pump water from a lower reservoir to an upper reservoir for energy storage. During peak grid demand periods, the stored water is released back to the lower reservoir to generate electricity. Its main difference from conventional dam-type Hydropower plants lies in the number of reservoirs.

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 dataset represents the civil engineering construction and electromechanical equipment installation of a large-scale (>=300 MW) pumped-storage hydropower plant. The technical service life of the Hydropower plants is assumed to be 100 years in accordance with design specifications. During the construction and installation stage, the main material inputs include cement, reinforcing steel, structural steel, fly ash, timber, and explosives, while energy inputs primarily consist of diesel fuel and electricity used for construction and installation activities. Land occupation associated with the hub project and reservoir inundation of the Hydropower plants is also considered. For the decommissioning and demolition stage, it is assumed that metallic materials, including reinforcing steel, steel, iron, aluminum, and copper, as well as wood, are recycled at a rate of 90%, while all remaining materials are disposed of via landfilling.
