What Is ICOLD?
International Commission
On Large Dams wasfounded in Paris in 1928.
Initially ICOLD was a
commission of the WEC
Currently comprised of85 countries
and 10,000 individual members
Engineering Companies, Consultants,Builders, Development companies,
Scientists, Researchers, Engineers,University Professors, Governments,Financial Institutions, Associations..

Interests of Grand Inga dam
High Power Capacity around 40 000 MW
Regularity of the flow more than 7 000 h / year
Large production capacity More than 280 TWh / year
Exceptional cost of kWh generated less than 0,01 $ / kWh
Small impacts on Environment
Grand Inga will save more than 100 million Tons of fossil fuel each year

Hydropower potential in Africa
60 % of the African hydropower potential of 1100 TWh is concentrated
on 3 countries :
RDC 400 TWhEthiopia 160 TWhCameroon 100 TWh
3 among the 4 largest dams in the world are African but the largest
African Power plant is only at the 30th rank in the world
Grand Inga will produce 280 TWh / year which is more than the 5 largest
African dams cumulated. But those 5 dams store more than 10% of theworld reservoir storage (500 billion m3)

Now conditions are favorable to
develop Grand Inga for Africa
High Power Ministerial Declaration, J ohannesburg, March 9 2006had a strong message for hydropower
International lenders are favorable to dam and hydropower
Other energies are expansive and polluting
The Grand Inga kWh cost is very cheap
The interconnected high voltage African network is being constructed
The environmental impact of Gd Inga project is small
