The new dam is located on the Nile river in north western Ethiopia and is scheduled to be completed in 2017.
The dam will have a capacity to hold up to 66 billion cubic metres of water and generate about 15,100GWh of electricity per year.
The project will feature two powerhouses at the foot of the dam, one either side of the river, housing ten and five turbine units each.
