The World Bank and other financial institutions are expected to offer finance and South Africa has agreed to buy half of the power generated.
French, Belgian, Chinese, Brazilian and African engineers have, over 60 years, all hoped to dam the Congo. But decades of civil war, corruption, and the Democratic Republic of Congo's (DRC) reputation as a failed state have limited the hydropower developments at Inga Falls to two relatively small dams, built in 1972 and 1982.
These, dubbed Inga 1 and 2, have a theoretical capacity of 1 400MW but produce only about half that.
A new $20-billion development to generate a further 4 800MW was announced over the weekend in Paris with work planned to start in October 2015.
This would make the complete Grand Inga development the largest hydro project in the world, generating twice as much as the Three Gorges dam in China. In theory, say its backers, it could provide 40% of Africa's electricity needs.
The attraction of developing hydropower on the Congo, says the government, is that unlike most of the world's great dam projects it would not require tens of thousands of people to be relocated, nor would it block the river and result in significant environmental consequences. Because the Congo River around Inga is so vast and falls nearly 100 metres over a short distance, water can be diverted to create a massive new lake without disturbing its main flow.
"The impact on land use is very limited. The development can be progressive and carried out in a series of further phases, eventually providing 40 000MW of power," says the technical data for the proposed development.
The African Development Bank, World Bank, French Development Agency, European Investment Bank and Development Bank of South Africa have all shown interest in financing the next stage of the project. No developer has been chosen but Chinese, Korean and Spanish companies are said to be in the forefront.
Key to the project is South Africa's commitment this week to buy 2 500MW of capacity. "We have affirmed our commitment to the project by already provisioning for this purchase in our budgetary plan," said South Africa Ministry of Energy official, Garrith Bezuidenhoudt.
But the prospect of the local population getting power from Inga in the next 20 years is remote. Less than 10% of the population currently has electricity, with nearly all Inga 1 and 2 power going directly to multinational mining companies in the Katanga "copper belt". It is expected most Inga 3 power would travel 1 500 miles to power-hungry South Africa or large mines in Congo.
Bad track record
Giant hydropower schemes in Africa have a bad track record. "Projects such as Inga 1 and 2 have not unleashed economic development, but have been major contributors to African countries' unsustainable debt burden," said US-based International Rivers network which has led opposition to major dams around the world for 20 years.
In a letter last week to the World Bank president, Jim Yong Kim, International Rivers and 18 other civil society organisations and networks from Africa, Europe and the United States said the reality of large-scale dams seldom matched their expectations, mostly adding to debt problems and allowing powerful companies to cheaply exploit and export Africa's vast natural resources.
According to the groups, the International Energy Agency (IEA) has found that because of the continent's low population density, grid-based electrification, including through large hydropower projects, is not cost-effective for much of rural sub-Saharan Africa.
"Distributed renewable energy solutions such as wind, solar and micro hydropower projects are much more effective at reaching the rural poor. According to the IEA report, 70% of the world's unelectrified rural areas are best served through mini-grids or off-grid solutions," said the letter.
"In the DRC, the World Bank and other financiers have invested billions of dollars in the construction and rehabilitation of the Inga 1 and 2 hydropower projects and associated transmission lines over the past 40 years. After all this investment, 85% of the electricity in the DRC is consumed by high-voltage users, while only 6% to 9% of the population has access to electricity. We are concerned that the bank's proposed focus on large hydropower projects will write off electricity access for the majority of Africa's poor." – Guardian News and Media 2013
