Sustainable energy for China
An unprecedented wave of industrialization and increased quality of life have multiplied the demand for energy in China in next to no time. This redefines the dimensions of power generation and transmission completely.
Smallest unit gigawatt – sustainable energy for China
Huge reserves of renewable energy exist especially in the provinces in the west of the country. Huge hydropower plants generate power in the gigawatt range here, the Xiaowan and Manwan reservoirs in Yunnan, for instance. They are among the world’s largest reservoirs. But the power that is generated here is needed about 1,500 kilometers away: in the urban centers of the Pearl River delta in the south of the country.
UHV DC transmission technology from Siemens makes possible the low-loss transmission of more than five gigawatts of power at a voltage of ±800 kV. The world’s first UHV DC line is a milestone in power transmission and the result of impressive technological development work. It transmits five gigawatts of power from the mountain region Yunnan to the coastal province Guangdong. The extraordinarily high voltage level demands system components of unprecedented size and completely new technological solutions.
Wind power plays an increasingly important role in the sustainable and resource-saving generation of electric power in China. The installed wind power capacity already amounts to more than 40 gigawatts, making the country the world’s largest wind energy market. And the goals for the foreseeable future are even more impressive: A total installed capacity of 150 GW is meant to be achieved by 2020.
Siemens is one of the world’s leading enterprises in the development and construction of wind energy plants and keeps pushing the envelope. About 30 years of experience in wind energy are the basis for reliable technology that enable the highly profitable utilization of on- and offshore wind resources. Locally, Siemens contributes to the implementation of the ambitious Chinese plans with new production plants for rotor blades and nacelles in Shanghai.
Fossil power generation, in China predominantly coal power, will remain the backbone of reliable energy supply for the foreseeable future. This makes the power plant efficiency even more important. High efficiency rates are the key to increased sustainability and higher profitability.
One of the world’s most efficient power plants, for instance, is the Waigaoqiao III power plant. Together with Shanghai Electric, its Chinese partner, Siemens delivered two 1,000 megawatt turbine and generator sets for this plant, which boasts an efficiency rate of more than 46 percent and uses an annual 900,000 tons less coal as well as emitting 1.9 million tons less CO2 than the world average. Moreover, Siemens provides the technological basis for sustainable improvements to the Chinese energy mix with gas and steam power plants, combined cycle power plants, and solutions for the oil and gas industry. Siemens produces highly efficient gas turbines and gas turbine generators in cooperation with Shanghai Electric.
