Included activities starts

The boundary of production activities starts from the time when the reservoir of the completed Hydropower plant begins to impound water and prepare for power generation.

Included activities ends

The boundary of production activities ends when electricity reaches the grid connection point of power generation.

Description

This dataset represents electricity generation from medium-scale (>=50, <300 MW) dam-type hydropower plants in a specific region, with a technical service life of 50 years based on design specifications. The data are primarily derived from official statistics.

Activity Description

The operational boundary of the product's production covers the entire operation and maintenance phase of a reservoir-type Hydropower plant, including initial reservoir filling, releasing water to drive turbines for power generation, and routine equipment maintenance.

Process Description

The product is grid-connected electricity measured in kWh, with a voltage level of ≥35 kV.

Technology comment

The dam-type hydropower plant have one reservoir for regulation and storage. Here, medium-scale dam-type hydropower plants refer to those 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.
