The hydropower exploitation of the Inga river is a complex power generation scheme, which comprises the Inga I and Inga II hydroelectric facilities (already been built), the Inga III, and finally the Grand Inga. The first two schemes were constructed respectively in 1972 and 1982 and provide today the largest amount of grid electricity, despite their poor maintenance conditions. The third one is still at exploration stage, as the first phase in the construction of the 5 dam complex Grand Inga hydropower scheme, located 225 km from Kinshasa, and 150 km upstream of the mouth of the Congo into the Atlantic Ocean. The dam complex has an expected generating capacity of 42,000 MW, with 52 turbines each with a capacity of 750 MW, which will make it the world’s largest dam in terms of hydro-electric production. This is more than Congo can use today and much of the energy will be exported. It would be developed in seven phases beginning with Inga 3, which itself would have two phases. According to International Rivers, its two components would displace about 35,000 people (10,000 for Inga 3 “Basse Chute” and 25,000 for Inga 3 “Haute Chute”) . In addition to building the dam wall and Inga 3 hydropower plant by 2022, the project proposes a power line that would stretch more than 5,000km from the project to South Africa, through Zambia and Namibia. The costs are estimated around $14 billion only for Inga 3 and between $100 and $150 billion for the entire Grand Inga complex. Plans for the Inga dams date back to the '50s, when investors from France, Belgium, China, Brazil and also some African countries expressed interests. In 1972 and 1982, the Mobutu government of the Democratic Republic of Congo, then called Zaire finalized the construction of the first two schemes, Inga 1 and 2, with a total potential generation capacity of 2,132MW. Up to now, these two schemes have never operated to full capacity; according to International Rivers, in 2013 the dams were reported to have produced only 40% of their capacity.
