Main projects

Since 1957 Salini Impregilo has completed 20 major projects in Ethiopia, worth a total of €9 billion. Each project has had a significant impact on the economy of the country: generating electricity, supplying drinking water in urban and rural areas, developing road infrastructure and building hospitals and other constructions for the community.

From proving water to the capital Addis Ababa to the construction of the largest dam on the continent (GERD) – which will raise the country’s energy production capacity by 270% – Salini Impregilo has completed complex and ambitious projects in Ethiopia that fit perfectly into the country’s overall growth plan.

01

Koysha Hydroelectric Project

2016 -  ongoing

The Koysha hydroelectric plant is located in the south-west of the country and is the fourth plant in a cascading system on the Omo River, while upstream the Gibe I and II plants have already been completed and Gibe III is 98% complete. Koysha will have an installed capacity of 2,160 MW and generate 6,460 GWh of energy per year.

02

Grand Ethiopian Renaissance Dam

2010 -  ongoing

Built on the Blue Nile, the Grand Ethiopian Renaissance Dam is the most ambitious hydroelectric project in the country. Once completed, the dam will be the largest in Africa, enabling it to increase energy generation by 270%.

The project is one of the most ambitious infrastructure challenges in the world, requiring the diversion of the Blue Nile and employing over 9,000 workers.

03

Gibe III Hydroelectric Project

2006 -  2016

The Gibe III hydroelectric plant is the third project in the Gibe-Omo cascading system and it is now the largest hydroelectric station in the country. Thanks to Gibe III, Ethiopia's power generation capacity will jump by 85%.

In fact, its 10 Francis turbines will generate an estimated 6,500 GWh per year. An average of 5,000 people have worked on Gibe III.

04

Beles Multipurpose Project

2005 -  2010

The Beles hydroelectric plant is located on the shores of Lake Tana, about 50 km north-west of Bahir Dar in the Amhara region. The project involved around 4,000 workers from 34 different countries.

Built almost entirely underground, the plant is characterised by a 11.8 km long pressure tunnel that carries the water from Tana Lake to the underground power station, where there are four Francis turbines, each of which are located capable of generating 115 MW of power.

05

Gilgel Gibe II Hydroelectric Power Plant

2004 -  2009

The Gilgel Gibe II power station is the second of the three plants in the Gibe-Omo hydroelectric cascade. Located about 250 km south-west of Addis Ababa, the plant was commissioned by Ethiopian Electric Power as an extension of the Gilgel Gibe I project, in turn part of the larger project to transform the country into a major producer of energy.

The power plant uses the same reservoir formed by the existing dam and can achieve annual output of 1,650 GWh. Inaugurated in 2009, the project consists of a 26 km hydraulic tunnel, to date the longest in Africa, with a 50 m gravity dam and a surface power station which houses four Pelton turbines with an installed capacity of 420 MW.

06

Gilgel Gibe I Hydroelectric Plant

1999 -  2004

The first of the three major projects on the Gilgel Gibe River marks a turning point in the country’s energy development. When it began operations, the hydroelectric plant was able to produce 30% of Ethiopia’s energy. Located 270 km from Addis Ababa, the reservoir created by the dam is capable of holding 839 million m³ of water.

07

Dire Dam

1996 -  1998

The Dire dam was built to ensure the supply of water to the Ethiopian capital, Addis Ababa. The dam, which is located in the Oromia region, is 1,997 m long and 48.5 m high, with adduction and water transfer systems extending over 10 km.

08

Chida Sodo Feeder Road Project

1994 -  1998

The road runs for 160 km and is divided into two sections. The first (Chida-Waka) is 73 km long, while the second (Waka-Sodo) extends 87 km. The work also included the construction of 5 bridges with 40 m spans and an iron bridge with a 90 m span on the Omo River.

09

Tana Beles Project

1986 -  1992

Tana Beles is a one-of-a-kind integrated project that was begun in Ethiopia after the years 1984-1985, which as in other regions of Africa had seen a terrible drought in Ethiopia. In Ethiopia, the drought affected about 70,000 people, who were left malnourished and suffering from tuberculosis and malaria.

In addition to emergency management, Salini Impregilo committed to the construction of two dams (Beles 1025 and Little Beles), both of which are close to the eponymous river, a tributary of the Blue Nile. Once operational, the dams helped to restore water management in the region, covering an area of 1,600 km2 and responding to the water needs of 80,000 people.

10

Legadadi Dam

1964 -  1970

Commissioned by the city of Addis Ababa, the Legadadi Dam is part of a wider program for the urban water supply. The main concrete hollow-gravity dam measures 46 m high and 450 m long, ensuring 40Mm3 of water for the city.

11

Lekempti-Gimbi Road

1964 -  1968

Nicknamed "The Coffee Road”, the Lekempti-Gimbi Road is 110 km long and mainly covers a mountain route. It has facilitated the transport of goods – including coffee of course – and people. More than 1,200 were involved in its construction between 1964 and 1968.

12

Cableway and reinforced concrete works at Addis Ababa

1962 -  1964

Works include the erection of a cableway and the construction of road 23 km long for the transport of mineral ore from the quarry in the Mugher Valley, previously inaccessible by road.

13

Koka Hydroelectric Project on the Awash River

1958 -  1960

The project involved the construction of a mixed buttress/gravity concrete dam with in-built spillway.

This implied: preliminary works for the diversion of the river; civil works related to the dam, intake, penstocks and power plant; the supply and installation of all the electromechanical equipment for the plant, intake and the substation, as well electrical connections to the cities of Addis Ababa and Dire Dawa.
