Under construction

1. Tekeze Hydropower DAM

Upon completion at the end of February 2009, the Tekeze Concrete Arch Dam in Ethiopia became the highest dam on the African Continent

Tekeze project description

Tekeze hydro power project is comprised of a double curvature (logarithmic spiral) concrete arch dam and appurtenant works, two river diversion tunnels, a 75m high power intake structure, power waterways (headrace tunnels, vertical pressure shaft, manifold, and four steel lined penstocks and four tailrace tunnels), an underground powerhouse containing four 75MW Francis turbines, outlet works, a 230kV substation and a 105km long double circuit transmission line, connecting to the Ethiopian national grid at Mekele.

At 188m high, the Tekeze Arch Dam ranks as the highest dam in Africa, eclipsing the previous record height for an African dam of 185m held by the Katse Arch Dam in Lesotho.

construction stage: trial Generation (100%)












2. Gilgel-Gibe II Hydroelectric Project



Gilgel Gibe II is a continuation of Gilgel Gibe I project which involved the building of a conventional dam with 917 million m3 lake and is able to generate 184 Mega Watts of electric power. The new plant, to be built under Gilgel Gibe II project, does not need a dam to be constructed. Instead, it will use the water discharged by the Gilgel Gibe I plant, channeled through a 26km tunnel under Fofa mountain, to Omo River Valley where it will harness 500 meter drop to generate 420 Mega Watts.

contractor: SALINI costruttori SpA

construction stage: trial Generation (100%)


3. Tana Beles hydropower project



construction stage: under construction (80%)

contractor: SALINI costruttori SpA


4. GIBE III HYDROELECTRIC PROJECT



The objective of the project is to enhance the hydropower generation capacity of the country through developing a plant with a capacity of 1870 MW and with an annual energy production of 6,500 GWh, This in turn is expected to raise the present 800 MW installed capacity of the country by 234 percent.

Moreover, the project has the aim of ensuring exportation of power to the neighboring countries through regional Interconnection Transmission System so that Ethiopia will be in a place of gaining hard currency through sells of electricity.

Turnkey Contract Agreement adopted for the Gibe III Hydroelectric Project was issued by the Federation International Des Ingenieurs Conseils (FIDIC). The Agreement was signed between the Ethiopian Electric Power Corporation (EEPCo) and Salini Costruttori S.p.A of Italy (Contractor) on 19 th July 2006. Amendment was also made on the Contract Agreement on April 22, 2008 since changes happened to the scope of the work.

As far as the quality inspection is concerned, the quality control of the design and construction is carried out by a Joint Venture Consultant- ELC Electrocosult (Italy)& Coyne et Bellier(France) is hired by EEPCo as Employer representative.

Regarding the structure, the basic design of May 2006 foresaw a Rockfill Dam with a large spillway structure on the right bank and the power intakes, headrace tunnels, penstocks/manifolds, surge shafts, powerhouse, and switchyard on the left bank. However, due to difficulties with obtaining proper and sufficient insurance coverage for the Rockfill Dam, the dam has been changed to Roller Compacted Concrete (RCC).

The Gibe III hydroelectric Project which is anticipated to be completed on July 2013 has a construction cost of 1,470 Million Euro (20.7 Billion Ethiopian Birr).

construction stage: Under construction (36% completed)

contractor: SALINI costruttori SpA

5. Fincha Amerti Neshe



6. Gilgel Gibe IV hydropower plant

Gibe IV will have an installed capacity of 1479 MW and the investment cost is estimated at 1.4 billion euros.

contractor: Sinohydro Corporation Limitted

construction stage: Under MoU

7. Genale Dawa III Hydro Power Project


located in the border between Oromia and Somalia regional states, the project, worth 408 million dollars, involves constructing a 110 metre high dam on the Genale River. This plant will be developed to have a capacity of 254MW.

contractor: China Gezhouba Group International Engineering Co. Ltd (CGGC)

construction stage: Under contract signing

8. Chemoga Yeda hydropower project


The Chemoga Yeda project, on the outskirts of Debre Markos, 299Km north of Addis Abeba in the Amhara Regional State, is expected to cost 555 million dollars. It will be carried out in two stages. This project will be completed in four years and nine months, according to the plan, and will involve the construction of five dams at Chemoga, Yeda, Sens, Getla and Bogena rivers. The reservoirs of these dams will be interconnected and the project is expected to generate 250MW.

contractor: China Gezhouba Group International Engineering Co. Ltd (CGGC)

construction stage: Under contract signing

Unfortunately, Egypt is trying hard to block any funding going to these projects.
Very Very SAD

Who is consulting Egypt before funding the projects? Any way the best way is to fund such projects by ourselves. I believe the time we do so is coming.

east africa is in the midst of a devastating drought--in Ethiopia, the dry spell has left close to 14 million people dependent on food aid. When assigning blame, aid workers and politicians finger the usual suspects: lack of rain, climate change, and an underdeveloped agricultural sector. But they're forgetting one: Egypt. Thanks to a 1929 agreement between *Britain--*acting on behalf of its East African *colonies--and a newly independent Egypt, Cairo holds the rights to two thirds of the Nile's water, as well as veto power over upstream projects. The disparity is stark: Ethiopia is the source of 60 to 80 percent of the Nile's flow, but uses less than 1 percent of it because Egypt says no to large-scale irrigation projects. And though Ethiopians might be tempted to circumvent the anachronistic arrangement, they can't. Egyptian officials work "behind closed doors" to block funding for upstream projects, according to David Shinn, a former U.S. ambassador to Ethiopia. The Nile states want to re-negotiate the ancient treaty, but Egyptian officials have stalled for years. And there's no sign they'll slake their neighbors' thirst any time soon.
This pisses me off!! This should get more media attention, the international community should all be aware of what they are doing.

This is how they repay Ethiopia for helping them get out off british conolization.

Thanks good thread,
Btw ethiopia will earn cash money by exporting electricity to this neighbors:



Ethiopia: Sudan’s national Electric agency is set to buy power from Ethiopia

July 22nd, 2009 Leave a comment Go to comments


Sudan’s national Electric agency is set to buy power from Ethiopia early next year after grid installation was completed last week.

Mr Saddiq Haroun, manager of the Ethiopia- Sudan power linkage project, told the Nation that a 157km power grid installation was done from Gedarif region of Sudan to Ethiopian west border.

The entire project will cost $35 million and India’s Import export Bank is to provide $25 million as loan to the Sudanese government.

The power grid consists of 400 towers which have a capacity of carrying 220KV.

Ethiopia is set to generate 4000 megawatts of electricity in the coming one year, which is double the national consumption.

Ethiopia has an agreement to export hydroelectric power, 200 Megawatts to Djibouti, 500 megawatts to Kenya and 200 megawatts to Sudan.

Currently, Ethiopia faces a serious power shortage and has been forced to ration power

After every one day there has been no power service all over the country, since last May 2009.

Ethiopia is building more than five big hydro-electric dams including the controversial Gibe 3 which is said to affect the flow of water from Ethiopia’s Omo River to Lake Turkana in Kenya.

About exporting energy: Even though the plan is a bit delayed due to current power shortage and unexpected demand increase in the country the plan is well underway. i think after the completion of the major stations the plan will resume. Here are the current and future interconnection.

existing and under construction power facility and transmission



Planned interconnection with neighboring country



Am surprised Eritrea is missing in this plan but hopefully they will drop the non-sense and come on board for this power integration project which create interdependence between neighboring country and lead to stabilizing the region and economical integration.

While the rest of the world was patting itself on the back for using 5% "green" sources of power, Ethiopia was going all out.

Tekeze hydropower Africa’s first ever biggest power dam inaugurates

Ethiopia opens 300 MW dam, starts producing 80 MW
Sun Nov 15, 2009 10:21am GMT

Print | Single Page
[-] Text [+]

ADDIS ABABA (Reuters) - Ethiopia opened a dam on Saturday that it says will produce 300 MW of hydropower as part of efforts to overcome chronic energy shortages and become one of Africa's only power exporters, state media said.

Power shortages are common in Africa and have hindered investment, even though the continent has abundant potential resources of solar, hydro, oil, gas, coal and geothermal power.

The Tekeze Dam has started producing 80 MW and that will rise to 300 MW, state-run Ethiopian Television said. It did not say when the dam would reach full capacity.

The dam is on the country's Tekeze river and its $356 million cost was financed by the China National Water Resources and Hydropower Engineering Corporation.

At 185 metres, it is the tallest hydroelectric dam on the world's poorest continent.

Outages have been common in Ethiopia for five years. The country rationed power for over five months this year with lights going off every second day, closing factories, hampering exports and fuelling a shortage of hard currency.

Ethiopia has six other hydropower dam projects being built, some funded by the World Bank. Government officials say the Horn of Africa nation will become a net power exporter within 10 years, exporting to Kenya, Sudan and Djibouti.

The country in September agreed deals with another two Chinese firms, China Gezhouba Group Company and Sinohydro Corporation, to build two huge hydropower projects.

EEPCo has also signed a preliminary agreement with the Hydrochina company for the construction of two wind farms to be reserved for emergency power shortages.

China has displaced many western countries as the major investor in Africa, where it has pumped billions of dollars into securing access to Africa's commodities. Ethiopia says it will spend $12 billion over 25 years to improve its power supply.
