All Four Turbine Units Start Generating Electricity at Yangfanggou Hydropower Station on Yalong River

2021-10-20

The No. 4 unit of hydraulic turbines of the Yangfanggou Hydropower Station on the Yalong River started commercial operation after 72-hour trial run on October 16, 2021. This marks that all four units of the hydraulic turbines of the Yangfanggou Hydropower Station have begun generating electricity commercially.

The Yangfanggou Hydropower Station is the country's first 1-million-kilowatt level mega hydropower project that adopts EPC (engineering-procurement-construction) model. The project has a 155-meter-high, double curvature arch concrete dam and is equipped with four sets of 375,000-kilowatt Francis turbine generator units, with a total installed capacity of 1.5 million kilowatts. After all four units are put into operation, the Yangfanggou Hydropower Station will annually produce clean energy that equals to about 2.3 million tons of standard coal, which will help to reduce carbon dioxide emissions by about 4.75 million tons and cut down sulphur dioxide emissions by about 34,000 tons, making active contributions to the country's "double carbon" target (peaking carbon dioxide emissions before 2030 and achieving carbon neutrality before 2060).

Among all the 1-million-kilowatt level hydropower projects, Yalong Hydro is the first to adopt the EPC model, which is a "bold" innovation of construction mode. The EPC model deeply integrates engineering with scientific research and construction, and optimizes all resources to tap the great potential of all participants and substantially increase project efficiency and returns.

The EPC model adopted by the Yangfanggou Hydropower Station has created "1+1>2" effects and quite a few "firsts" in the country, including: the first smart management system for smart dam construction quality of large-type hydroelectric project with EPC model; the first large-type hydroelectric project to have all-aspect and whole process engineering supervision during construction, and the first large-type hydroelectric project to have complete, highly efficient and reliable engineering supervision management system and process.

Zhang Ye, Director-General of China Society for Hydropower Engineering, said that the exploration and practice of large-type hydroelectric project EPC construction management pioneered by the Yangfanggou Hydropower Station on the Yalong River offers a new development direction for transforming and upgrading the hydroelectric market under the new normal and sets an example for hydroelectric project construction in the country.
