Description
This dataset represents the civil engineering construction and electromechanical equipment installation of a medium-scale dam-type hydropower plant with an installed capacity of ~129.2 MW. The technical service life of the Hydropower plants is assumed to be 50 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.
