Grand Ethiopian Renaissance Dam, Ethiopia

Name of the Project
Grand Ethiopian Renaissance Dam (GERD).

Location
The GERD is located on the Abay river, in the Beneshangul Gumuz region of Ethiopia.

Project Owner/s
Ethiopian Electric Power Corporation (EEPCo).

Project Description
The project envisages a plant with an installed capacity of 6 000 MW that will supply 15 692 GWh/y.

The major components of the project include:
• a 145-m-high, roller-compacted concrete (RCC) dam with a 1 780-m-long crest;
• a rock-filled saddle dam, 4 800 m long and 45 m high, with 24 upstream bituminous facing;
• two outdoor powerhouses of 3 750 MW and 2 250 MW installed capacity, containing ten and six generating units respectively, each with a capacity of 375 MW; and
• a 500 kV switchyard, which will transmit power from the two powerhouses to the grid.

The main dam and saddle dam will create 74-billion cubic metres of impounding capacity, with a surface area of 1 680 km2 at full capacity.

A gated spillway, equipped with six radial gates and a discharge capacity of 14 700 m3/s at probable maximum flood occurrence, will be located on the left side of the main dam.

A saddle dam on the left side of the RCC dam, with an emergency side spillway, is envisaged to allow for the discharge of flood water directly into the Roseires reservoir.

The construction of 123 km of access roads, as well as camps, workshops and other civil works, form part of the activities for the project.

Potential Job Creation
Not stated.

Capital Expenditure
The project is valued at an estimated $4.8-billion.

Planned Start/End Date
In January, Ethiopia's Water and Energy Minister said that following construction delays, the dam would start production by the end of 2020 and be fully operational by 2022.

Latest Developments
Ethiopia’s Prime Minister Abiy Ahmed Ali has asked South Africa’s President Cyril Ramaphosa to intervene in the Nile dam deadlock between Egypt and his country.

Ethiopia has said that broader talks have reached a deadlock following Egypt’s introduction of new proposals to fill the dam in 12 to 21 years.

“We are willing to play a role in whatever agreement that can be crafted, and we will remain supportive to finding peaceful solutions between countries on our continent,” President Ramaphosa has said.

Tensions have flared over the dam with regard to an agreement on how to fill the reservoir.

Key Contracts and Suppliers
Salini Costruttori, a subsidiary of Salini Impregilo; GE Hydro France, China Gezhouba Group Corp, Voith Hydro Shanghai and China's Sinohydro Corp (construction contract); Alstom (turbine and generators).

On Budget and on Time?
Construction on the dam is five years behind schedule and well over its original €3.4-billion budget.
