Sustainable energy for China
Virtually endless power resources are available in the mountains of the Yunnan province in Western China: hydropower. The most energy-hungry areas, however, are situated in the Pearl River Delta in the country’s southeast. The growing urban centers there require reliable power supply.
Hydropower lights up megacities – power transmission in China
Siemens helps ensure this supply with a cutting-edge direct current transmission system. The advanced UHV DC system, which operates at a transmission voltage of 800 kV, is over a thousand kilometers long and brings the power to the Pearl River Delta in an economical and eco-friendly way.
The Yunnan-Guangdong DC system takes HVDC transmission to the next level:
Siemens is a global leader in power transmission systems. All over the world, innovative high-voltage direct-current (HVDC) technology ensures the efficient connection of power generation sites with centers of consumption. It connects offshore wind farms to the mainland and transmits power over long distances with minimum losses. Siemens power transmission systems contribute to the grid integration of renewable energy sources as well as to the sustainable expansion and upgrade of grid infrastructures around the globe. Its broad range of innovative products and solutions places Siemens in an outstanding position to help meet increasing worldwide demand for electric power.
Demand for electricity is skyrocketing in China due to an unprecedented wave of industrialization and generally increased quality of life. China is the fastest growing market in the field of power transmission and distribution and will become the world’s largest single market for HVDC transmission technology over the next 20 to 30 years. Siemens is a leading supplier of this technology and provides solutions that help meet the soaring demand in an economically efficient, sustainable, resource-efficient, and reliable manner.
Together with its local partners, Siemens provides the technological basis for sustainable improvements to the Chinese energy mix: Steam, gas, and combined cycle power plants that take efficiency to the next level. It also contributes to integrating an increasing amount of renewables into the energy mix, for instance through manufacturing rotor blades for wind turbines in Shanghai. And finally, UHV DC transmission technology from Siemens makes possible the low-loss transmission of five to eight gigawatts (at +/- 800 kV DC). of power from remote regions to the urban centers where power is needed most.
Many Siemens products help reduce our environmental footprint and combat climate change. These products make up the Siemens Environmental Portfolio and usually offer a threefold advantage: They benefit the customers through low energy costs and higher productivity. They help protect the environment and the climate. They preserve and improve the living and environmental conditions of future generations.
The Siemens Environmental Portfolio largely consists of capital goods with long life cycles. It mainly comprises products and systems, such as combined cycle power plants and intelligent building technologies, that are far more energy-efficient than comparable solutions, renewable energy systems and components, such as wind turbines and steam turbines for solar-thermal power plants, and environmental technologies for cleaner water and air. To qualify for the Siemens Environmental Portfolio, which is annually approved by the Siemens Sustainability Board and reviewed by independent auditors, a product or solution must fall into one of these three categories.
