21 April 2008 - Seven African governments and the world's largest banks and construction firms meet in London today to plan the most powerful dam ever conceived - an $80bn, 40 GW hydropower project on the Congo river, which could double Africa's power capacity.
According to the UK newspaper The Guardian, G8 and some African governments hope that the Grand Inga dam in the Democratic Republic of Congo will generate twice as much electricity as the world's current largest dam, the Three Gorges in China, and expect the dam to export electricity as far away as South Africa, Nigeria and Egypt, and even Europe and Israel.
Two hydroelectric plants, known as Inga 1 and Inga 2, were constructed near there in the 1970s and a third is planned, but Grand Inga is intended to dwarf them all. One feasibility study suggests the 40 GW dam will be 150m high, and will harness 26 000 cubic metres of water a second, with more than 50 turbines each producing nearly as much power as a British nuclear reactor.
Grand Inga was proposed in the 1980s but never got beyond feasibility studies because of political turmoil in central Africa. But now it stands a chance, according to Gerald Doucet, secretary general of the World Energy Council thinktank, which is convening the London meeting.
"It is the greatest sustainable development project, offering Africa a unique chance for interdependence and prosperity," said Doucet. "It's much more feasible now than ever. There is a peace settlement in Congo, and economic and technical studies have all shown it is possible."
Grand Inga's prospects of being completed by 2022 are said to have risen significantly in the last year as countries, banks and private companies have found they can earn high returns from the emerging global carbon offset market and UN climate change credits.
In return for investments in clean power, rich countries such as Britain hope to be able to offset their own greenhouse gas emissions against the renewable energy that dams such as Grand Inga would produce, and constructors are making windfall profits out of renewable energy projects in developing countries.
