Ethiopia, the second most populous country on the continent, has the second biggest electricity deficit in Africa according to the World Bank, with about two thirds of the population of around 110 million lacking a connection to the grid.
The project will ultimately cost $5 billion when it is completed and become the biggest hydropower plant in Africa by generating 5,150 MW of electricity, some of which will be exported to neighbouring nations, the government says.
The government has so far invested more than 100 billion Ethiopian birr ($1.98 billion) in the project, state-affiliated FANA broadcaster reported. It is located at a place called Guba in the western Benishangul-Gumuz region.
