International rivers and river communities rights nongovernmental organisation International Rivers has called on South Africa to withdraw its agreement to offtake electricity from the Inga 3 hydropower project being built in the Democratic Republic of Congo (DRC). South Africa continues to uphold its commitment to procure power from the delayed Inga 3 hydropower dam, but the power imported from Inga is expected to cost R175-million a year more than domestic power generation, the NGO avers.
