South African utility Eskom has named Voith Siemens Hydro Power Generation to equip the 1,368-MW Ingula pumped-storage project on the border of South Africa’s Free State and KwaZulu-Natal.
Eskom is developing Ingula in the Little Drakensberg Mountains near Ladysmith. (HNN 4/4/08) Completion is scheduled for 2013.
Officials of Eskom and Voith Siemens signed the 140 million euro (US$202 million) contract September 1 in Johannesburg.
Voith Siemens is to supply complete electro-mechanical equipment, including four pump-turbines of 342 MW each, four motor-generators, and complete automation and control systems.
The company’s German and Japanese operating units are joint partners in the project to design and manufacture the equipment. Motor-generators are to come from Kawasaki in Japan, with pump-turbines supplied by Voith Siemens’ Heidenheim, Germany, plant.
Ingula is to feature two dams, one forming a reservoir on Bedford Stream atop the Drakensberg escarpment and the other at the bottom at the Braamhoek River. The project includes water tunnels, an underground powerhouse complex, access tunnels, and access roads. Eskom already is carrying out tunnel excavation.
