Xiangjiaba–Shanghai HVDC System
The Xiangjiaba–Shanghai HVDC system is a ±800 kV, 6400 MW high-voltage direct current transmission system in China. The system was built to export Hydroelectricity, hydro power from Xiangjiaba Dam in Sichuan province, to the major city of Shanghai. Built and owned by State Grid Corporation of China (SGCC), the system became the world’s largest-capacity HVDC system when it was completed in July 2010, although it has already been overtaken by the 7200 MW Jinping–Sunan HVDC scheme which was put into operation in December 2012. It also narrowly missed becoming the world’s first 800 kV HVDC line, with the first pole of the Yunnan–Guangdong HVDC, Yunnan–Guangdong project having been put into service 6 months earlier. It was also the world’s longest HVDC line when completed, although that record is also expected to be overtaken early in 2013 with the completion of the first bipole of the Rio Madeira HVDC system, Rio Madeira project in Brazil.

Inga–Shaba HVDC
The Inga–Shaba EHVDC Intertie (officially: The Inga–Shaba Extra High Voltage D.C. Intertie; nickname: Inga–Shaba and also referred to as Inga–Kolwezi) is a -long high-voltage direct current overhead electric power transmission line in the Democratic Republic of Congo, linking the Inga Dam, Inga hydroelectric complex at the mouth of the Congo River to mineral fields in Katanga (province), Shaba (Katanga).Compendium of HVDC schemes, International Council on Large Electric Systems, CIGRÉ]Technical Brochure No. 003 1987, pp136-141. It was primarily constructed by Washington Group International, Morrison-Knudsen International, an American engineering company, with the converter equipment supplied by Allmänna Svenska Elektriska Aktiebolaget, ASEA. Construction was completed in 1982 and it cost United States dollar, US$900 million. The scheme was, for many years, the longest HVDC line in the world.
