Voith Hydro of Germany and Voith Hydro Shanghai have been awarded a joint contract to supply electro-mechanical works for Pakistan's 1,410-MW Tarbela 4 hydropower project extension.
Offered by Pakistan's Water and Power Development Authority (WAPDA), the US$312 million contract includes the design, supply, installation, commissioning of equipment.
Per a tender last offered by WAPDA in February 2013, the Voith group is to provide three vertical-shaft Francis turbines and 470-MW generators, main inlet and relief valves, generator transformers, 500-kilvolt SF6 circuit breakers, switchgear, control instrumentation, supervisory control and data acquisition (SCADA) systems, and other associated powerhouse equipment.
The Tarbela 4 extensions will add a fourth powerhouse to the 3,478-MW Tarbela project, which is located on the Indus River.
The World Bank is reportedly providing $840 million of the expansion's $928 million pricetag. Work is expected to take 42 months.
HydroWorld.com reported in March of this past year that repairs to three of Tarbela's existing turbines had been completed with funding from the United States Agency for International Development (USAID), increasing the project's capacity by 128 MW.
