China wants to further expand its hydropower with the two largest Pelton turbines in the world. Each of these giants from the manufacturer Harbin Electric Has an outer diameter of 6.20 meters, weighs 88 tons and has an output of 500 megawatts. Previously built turbines of this type come to a maximum of 300 megawatts. So that the huge forces that act on the 21 shovels do not destroy them, they consist of so -called martensitic steel. This is rust -free and is particularly resistant due to its special crystal structure.
Water from great height
The turbines are intended for the Datang Zala power plant in Tibet. The yuques, a smaller tributary of the nu in the east of Tibet, which leads relatively little water, but still has great strength. The Chinese engineers have blown up a pressure line in the rock, through which the water of the river, which is dammed, falls 671 meters into the depths and captivated by the blades. The shape of the shovels has been optimized in four years, so that the mighty wheel implements the kinetic energy of the water to 92.6 percent in rotation. So far, an efficiency of 91 percent has been common.
The power plant is said to deliver four billion kilowatt hours of electricity each year. In a coal -fired power plant, 1.4 million tons of fuel would be necessary, which would emit 3.7 million tons of CO2. The power plant builds the China came Corporationoperates the systems with a total of 200 gigawatts. According to their own statement, 49.66 percent of them are water, wind and solar power plants as well as a storage power plant based on compressed air.
Commissioning 2028
The construction of Datang Zala began in 2023. The power plant is scheduled to generate the first electricity in 2028. It is part of the comprehensive efforts of China to expand the proportion of renewable energies. Since 2020, Beijing has promoted the construction of dams, as a contribution to the goal of reaching CO2 neutrality by 2060. The performance of all Chinese hydropower plants is around 436 gigawatts. For comparison: In the USA it is a good 100 gigawatts, 16 gigawatts in Germany. This includes systems that constantly generate electricity such as running hydropower plants and pumped storage power plants that only step in when there is a lack of electricity.
