Shanghai Temple Project

The Shanghai Temple–Shandong Linyi ±800 kV Ultra-High Voltage Direct Current (UHVDC) transmission project is one of the major "Four Horizontal and Four Vertical" corridors under China's 13th Five-Year Plan for energy conservation, emission reduction, and West-to-East Power Transmission. It is also a key project of the Air Pollution Prevention and Control Action Plan, constructed by the State Grid Corporation of China. The project was approved on December 1, 2015, and construction began on December 15, 2015. It starts from the Yikezhao Converter Station in Ordos, Inner Mongolia, and ends at the Yinan Converter Station in Linyi, Shandong, passing through six provinces and regions. The total line length is 1,230 kilometers, with a rated transmission capacity of 10,000 megawatts. It is the DC transmission project with the highest transmission power in China, and among the first to adopt layered access technology and be equipped with synchronous condensers.
