Rusumo Falls is an 80 MW hydropower plant being developed with financial support from a number of multi-national lenders, including the EU-Africa Infrastructure Trust Fund, African Development Fund, Nigeria Trust Fund and African Development Bank Group, amongst others. The project is to be located at Rusumo Falls on the border of Rwanda and Tanzania, with transmission lines interconnecting those countries and Burundi.
The 36.4-MW Red Rock hydroelectric plant is being built at an existing dam on the Des Moines River in Iowa, U.S. The powerhouse will be located downstream from the U.S. Army Corps of Engineers’ Red Rock Dam and contain two Kaplan turbine-generator units fed by an intake structure upstream from the dam. This rolled earthfill embankment dam with a gravity concrete control section is 5,200 feet long and 95 feet high above the flood plain and was built in the 1960s to provide flood control.
Tarbela Dam is 485 feet high above the riverbed and forms Tarbela Reservoir with a surface area of about 250 km2. The dam was built for water supply but power generating capacity was added in three “extensions” that were completed in 1992. The 700-MW Tarbela 1 (commissioned in 1977) features four units, 1,050-MW Tarbela 2 six units (four commissioned in 1982 and two in 1985) and 1,728-MW Tarbela 3 four units (commissioned in 1992 and 1993).
The Site C Clean Energy Project will be the third hydropower facility on the Peace River. The hydroelectric complex is expected to cost C$8.353 billion (US$6.3 billion) to develop, with a British Columbia Government Treasury reserve of C$400 million (US$302.8 million). The powerhouse will contain six 183-MW turbine-generator units. When complete, it is expected to generate about 5,100 GWh of electricity annually.
The Grand Inga project is a massive US$80 billion expansion to the existing 351-MW Inga 1 and 1,424-MW Inga 2 plants. The ultimate goal is to construct a complex capable of supplying the entire sub-Saharan region with a cumulative output capacity of 42,000 MW. The Democratic Republic of Congo is currently working to tender and begin construction of the project’s first expansion, the 4,800-MW Inga III.
The Belo Monte hydropower plant features two powerhouses, one with 18 Francis turbine-generator units and a total capacity of 11,000 MW and another (called Pimental) with a total capacity of 233 MW. The hydroelectric complex is expected to cost US$26 billion to develop. When complete, Belo Monte will be the third largest hydro facility in the world in terms of generating capacity.
