10 Largest Dams In Africa.
The continent of Africa in the last decade has seen a
resurgence in construction of massive dams,
in order to supply more regulated water and
to generate hydroelectricity
Africa is home to some of the world's largest dams
as the world transitions to cleaner forms of power, Africa seems to lead this movement
with construction of dams taking place in several countries and many more switching to clean energy
Dams have been a reliable source of hydroelectric energy for decades,
generating substantial amounts of electricity globally
In this video, we are going to look at the 10 Largest Dams In Africa.

10} Meroe Dam, Sudan.
Downstream on the Nile less than a decade ago,
Sudan completed the Meroe dam
The dam has a length of about 9 kilometers(5 miles), and a crest height of up to 67 meters
it consists of concrete-faced rock-filled dams on each river bank.
The dam has the capacity
to generate 1250 megawatts from 10 Francis turbines each having a capacity of 125 megawatts
The total project cost is reported to be 2.945 billion US$, and was inaugurated on march 2009.
9} Inga Dams, DRC.
Comprised of two single dams; the Inga I producing
351 megawatts, and inga II producing 1424 megawatts
in the Democratic Republic of Congo
which currently operates at a combined capacity of 1775 megawatts.
Built on the Inga falls, "one of the largest waterfalls in the world",
the hydroelectric dams currently work at nearly half of their potential capacity
Expansion of the dam has generated interest from nations, and power companies all over africa
that have expressed interest in the pursuit of a Grand Inga project estimated to cost 80 billion US$,
which would become the largest hydropower station in the world
with a capacity of up to 70 gigawatts
8} Kariba Dam.
Located along the border of Zimbabwe and Zambia
Kariba Dam is one of the largest dams in Southern Africa
Plans to rehabilitate the dam started in 2014
after experts advised that it should be repaired as cracks emerged on its walls.
Kariba Dam is 128 meters
(420 feet high), and 579 meters (1,900 feet) wide.
The Kariba Dam rehabilitation project, will
ensure the dam is able to operate at its full capacity, and to international standards.
The dam has the capacity to produce 1830 megawatts of electricity
7} Koysha Hydroelectric Dam, Ethiopia.
The Koysha Hydropower Project is a 2.16 gigawatts hydroelectric facility under
construction on the Omo river in the Oromia region of Ethiopia
located on the Omo river in the Oromia regional state of Ethiopia
approximately 370 kilometers (220 miles), southwest of the capital city Addis Ababa.
The project involves the construction of hydroelectric facilities built on the Omo river
comprising of; Gebe I producing 200 megawatts, the Gebe II producing 420 megawatts, and Gebe III 1870 Mega Watts power stations
The construction of the dam will involve building of a 180 meters high
roller compacted concrete (RCC gravity dam), and a 250 meters long-41 meters wide and 60 meters high
surface powerhouse: equipped with eight Francis turbine units of 270 megawatts rated capacity each.
The RCC gravity dam with a crest length of 990 meters will create a reservoir capacity of
9 billion cubic meters (PCM)
The project also features a 330 meters long-and 42 meters high cofferdam
state-owned public utility enterprise Ethiopian Electric Power (EEP)
is developing the project with an estimated investment of approximately 2.8 billion US$.
In 2016, an Italian credit agency gave the Ethiopian government 1.6 billion US$ to
help financing of the project and the civil construction works began in the same year
6} Laúca Hydroelectric Power Station, Angola.
The Laúca Hydroelectric Power Station is
a 2 gigawatts run-of-the-river hydroelectric project located on the Kwanza River in Angola,
in Dombo-Ya-Pepe district.
The main construction works on the Hydroelectric Plant were started in
July 2013
while the first unit was commissioned in July 2017,
the sixth main unit was put
into operation bringing the total installed capacity to 2004 megawatts in December 2020
An environmental flow power plant of 65.5 megawatts capacity is also currently under
construction at the site, and upon its completion the Laúca hydroelectric plant's total capacity
will reach approximately 2070 megawatts.
5}Cahora Basa dam, Mozambique.
One of the two major dams on the Zambezi River
the Cahora Basa Dam in Mozambique is the largest
hydropower plant in Southern Africa.
Power is generated through five: 415 megawatts turbines,
making the combined capacity of the dam to be 2070 megawatts
Most of the power generated from the
Cahora Basa Dam is exported to South Africa through the Cahora Basa high voltage direct current
HEDC line system
with two conversion stations located in Tsongo-Mozambique,
and Apollo -South Africa.
4} Aswan Dam, Egypt
Located near the city of Aswan in southern Egypt,
the Aswan high dam is
one of the largest dams in Africa.
Built across the Nile, the dam is the largest embankment dam in the world
with a height of 111 meters. and a length of 4000 meters
Powering 12 generators
each at a rate of 175 megawatts
The dam has a total generation capacity of 2100 megawatts.
The dam was built between 1960s and 70s
with the aim at controlling floods, providing increased water storage
for irrigation and generating electricity.
3} Rufiji Hydropower Station, Tanzania.
Rufiji Hydroelectric Power Station also called Julius Nyerere Hydropower Station
is a 2115 megawatts 2,836,000 horsepower hydroelectric dam under construction in Tanzania.
The power station is expected to produce 5920 gigawatt-hours of power annually,
In August 2017, the Tanzanian government
made an official public announcement for plans to construct this dam
And In December 2018, "the Citizen" a Tanzania newspaper reported that the government of Tanzania had
awarded the construction contract for this power project to Arab contractors limited in Egypt
at a budgeted cost of 2.9 billion US$, and in February 2019, the government of Tanzania
handed over the construction site to the consortium comprising of arab contractors and
El Sewedy, both of which are Egyptian companies, had been selected to build the power station.
According to the Tanzania Energy Minister Mr. Medard Kalemani, the country's Energy Ministry
plans to increase the total installed capacity to 5 Gigawatts by 2021, and 10 Gigawatts by 2025.
2} Caculo Cabaca Hydro-Electric Power Station, Angola.
Caculo Cabaca Hydro-Electric Power Project
is a 2172 megawatts run of the river hydroelectric facility under construction in
the Kwanzaa Norte province of Angola
Angola is currently developing several major hydropower projects
Angola, "Africa's second-largest oil producer"
faces big power problems which hinders
the development of the country
Under the National Energy Development Program: The Angolan government
is expected to satisfy its increasing demand for electricity in the country and to foster local
social and economic development
The project is being developed by Angola's Ministry of Energy and
Water (MINEA) .
with a total estimated investment of approximately 4.5 billion US$.
Upon completion,
Caculo Cabaca is expected to be the biggest hydroelectric facility in Angola, surpassing the
2070 megawatts installed capacity of the Lauca hydroelectric power station
At full capacity,
the , Caculo Cabaça hydroelectric power station is estimated to generate up to 8123 gigawatt-hours of
electricity annually.
The Caculo Cabaça Hydropower Project comprises of a ; 103 meters high concrete dam
with a crest length of 553 meters, an underground powerhouse equipped with four 530 megawatts,
turbine generator units
as well as a 52 megawatts ecological power plant located adjacent to the dam,
and it is located 19 kilometers (11 miles) upstream of the Lauca Hydropower Station,
and approximately 270 kilometers (167 miles) east of Angola's capital city Luanda.
1} Grand Ethiopian Renaissance Dam
The Grand Ethiopian Renaissance Dam, it is the largest dam
currently under construction in Ethiopia
Located on the blue Nile about 15 kilometers
(9 miles) east of the border with Sudan
at 6.45 gigawatts the dam will be the largest
hydroelectric power plant in Africa when completed, as well as the seventh largest in the world.
The construction of the dam is over 80% complete, and upon completion, it will generate over 5150 Mega Watts
of electricity
The reservoir will take from four to seven years to fill with water,
on July 2020 first filling of the dam was done, and the second filling of the dam was done in July 2021
during Ethiopia's rainy season.
The primary purpose of the dam is electricity production to
relieve Ethiopia's acute energy shortage, and for electricity export to neighboring countries, and it
is also going to serve as a tourist attraction
This is by far the largest dam in Africa
