Gilgel Gibe I
Location: Ethiopia
Operator: Ethiopian Electric Power Corp
Configuration: 2 X 61.3 MW Francis
Operation: 2004
T/G supplier: Voith
EPC: Enelpower, Electroconsult, Salcost
Quick facts: This plant is near Jimma 260km
southwest of Addis on the Gilgel Gibe River. Development began in the
early 1960s and the site was selected after planning studies in the 1970s and 1980s. Construction by a consortium of
Ethiopian and North Korean firms began in 1988, but work stopped in 1994
before the dam was completed. In 1995, the government signed a new
agreement with an Italian consortium to undertake an environmental
impact assessment and complete design
and construction. Funding from the World Bank was used to complete the plant.

Tekeze
Location: Ethiopia
Operator: Ethiopian Electric Power Corp
Configuration: 4 X 75 MW Francis
Operation: 2009
T/G supplier: China Wanbao Engineering Co
EPC: MWH, Energoproject-Hidroinzenjering, SinoHydro, China Gezhouba
Construction, Sur Construction
Quick facts: In mid-2001, EEPCo issued a bid to build a 300-MW
power plant at the TK5 site on the Tekeze River in Tigray state 80km
west of Mekele. This project had a lengthy history as the engineering
consortium for Tis Abay-II produced feasibility studies, designs and
tender documents for a plant that turned out to be essentially on the
border with Eritrea. This location was abandoned and the project was
reborn at a different site. In Jun 2002, EEPCo awarded the EPC contract
to CWGS Joint Venture. At the time, the $224mn contract was the largest
cooperative project between China and an African country. The main
structure is a 185m, double-curvature concrete dam which is now the
tallest in Africa. Over 3,500 workers were involved in plant
construction, of which 750 were expats from four countries. Power
generation started in Aug 2009 despite the fact that the reservoir was
not completely filled.Photograph courtesy of Ethiopian Electric Power Corp

Tana New
Location: Kenya
Operator: Kenya Electricity Generating Co Ltd
Configuration: 2 X 4.3 MW, 2 X 5.5 MW Francis
Operation: 2010
T/G supplier: Resita, Turboinštitut
EPC: Farab, Hasish Engineering
Quick facts: Construction on the original Tana PS began in 1932. KenGen
decided to redevelop the scheme with a new 25-MW power station to replace
the old 20-MW plant. Two generators are fed by water from the Maragua
River, and two other units by water impounded by the Merila Barrage. On 22
July 2010, the first unit was put in operation and synchronized with the
grid. This power plant was Iran's first completed international hydro EPC
project.
