A long journey to transmit power across the country

China plans construct a “Strong and Smart Grid” by 2020 of which Ultra-high voltage (UHV) transmission is a core component. UHV power transmission capacity is expected to reach 450 GW in 2020, accepting 1.7 trillion kW of clean energy per year. ABB has so far participated in a number of national key high-voltage direct current transmission projects.

Eastern China is an engine of the Chinese economy and also a major load center in China. ABB participated in the ±800-kilovolt (kV) Sichuan Xiluodu-Zhexi Ultra-High-Voltage Direct Current (UHVDC) transmission connection in 2013, by supplying converter transformers, DC filter capacitors and key components for converter valves. The link travels over a distance of 1,670 kilometers, and is one of the world’s highest capacity power connections with a transmission capacity of 8,000 megawatt (MW). After the project is completed in 2014, the link will supply approximately 40 billion kilowatt-hours of clean hydropower per year – enough to meet the needs of over 11 million consumers - to the Western Zhejiang area.
