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 1,700 kilometres (1,100 mi)-long high-voltage direct current overhead electric power transmission line in the Democratic Republic of Congo, linking the Inga hydroelectric complex at the mouth of the Congo River to mineral fields in Shaba (Katanga). It was primarily constructed by Morrison-Knudsen International, an American engineering company, with the converter equipment supplied by ASEA. Construction was completed in 1982 and it cost US$900 million. The scheme was, for many years, the longest HVDC line in the world.
