Facts and figures about GERD
Where is GERD located?
GERD is located in Ethiopia close to the border with Sudan within the Regional State of Benshangul Gumuz.

What did the Construction of GERD start?
The construction of the GERD was inaugurated in April 2011 by late Prime Minister Meles Zenawi. The project was made public first as Millennium Dam and finally Grand Ethiopian Renaissance Dam and sometimes shortly referred as Renaissance Dam. The Dam was announced on March 12, 2011; a contract was signed with Salini and cornerstone placed on April 2, 2011.
What is financing the construction of the GERD?
The GERD is financed by the Ethiopian people through a sale of bond and cash contributions. The government employees, business owners, and citizens of Ethiopian origin in the diaspora participated in the purchase of the bond. For years financing from outside sources was blocked by Egypt and her allies, under the Leadership of the then Prime Minister Meles Zenawi the Ethiopian people realised self-financing is the only option.
What is the dam type?
The GERD is a roller compacted concrete dam. GERD’s water retaining structures include: the Main Dam, a roller compacted concrete (RCC) structure1,800 m long and 175 m high, and a Saddle Dam, a concrete faced rockfill (CFRD) structure, 5,000 m long and 60 m high, with embankment volume of 17 million m3.
What is the installed capacity of GERD and the expected annual generation capacity?
What is the type and number of turbines used in GERD?
It was planned to have an installed capacity of 6,450MW but recently the installed capacity was revised to 5,150 MW. The expected average annual energy production is 15,700 GWh.
What was the earlier planning effort started?
Initially, the Dam was planned to have 16 turbine units, but recent revisions reduced it to 13 turbines with similar energy output with the initial plan.
What is the latest planning and design of GERD conducted?
The site for the GERD was part of sites identified by the United States Bureau of Reclamation (USBR) in the Blue Nile survey, which was conducted during the administration of Aklilu Habtewold in the reign of King Haile Selassie I.
