Tekezé Dam
Tekezé Dam is a double-curvature arch dam located between Amhara and Tigray regions of Ethiopia. It is situated on the Tekezé River, a tributary of the Nile that flows through one of the deepest canyons in the world. Overview CWGS was contracted to build the Tekezé Dam. The hydroelectric project was completed in February 2009. Its final cost was $360 million, which was $136 million over budget. The dam was Ethiopia's largest public works project. The dam helped to reduce power shortages as Ethiopia's power demand increases. At the time of its completion, the Tekezé Dam was Africa's largest double-curvature arch dam. The resulting reservoir is 105 km2 large and it has a capacity of 9.3 billion m3 of water. Tekeze Power Station The powerhouse contains four turbines, generating of electricity. A transmission line connects it to the national grid at Mekelle. See also * Energy in Ethiopia * List of power stations in Ethiopia This page lists power stations i ...

Ethiopia
Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country located in the Horn of Africa region of East Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia covers a land area of . , it has around 128 million inhabitants, making it the List of countries and dependencies by population, thirteenth-most populous country in the world, the List of African countries by population, second-most populous in Africa after Nigeria, and the most populous landlocked country on Earth. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African Plate, African and Somali Plate, Somali tectonic plates.

Energy In Ethiopia
Energy in Ethiopia includes energy and electricity production, consumption, transport, exportation, and importation in the country of Ethiopia. Ethiopia's energy sector is crucial for its development, with wood being a primary energy source, leading to deforestation challenges. The country aims to address economic development and poverty by transitioning to alternative sources, particularly electricity. Overview The following table provides some of the most relevant energy sector numbers for Ethiopia, a developing country. The ''primary energy sector'' is by far the most important one in Ethiopia, with mainly wood used for cooking. That together with the population growth in Ethiopia results in issues like deforestation. Ethiopia aims at economic development and removal of poverty and to replace the use of wood by alternatives. This makes the ''secondary energy sector'' (with ''electricity'') most relevant for these efforts. Almost all recent developments are taking place in the ...

Reservoirs In Ethiopia
A reservoir (; ) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by creeks, rivers or rainwater that runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In The Nile Basin
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Water Politics In The Nile Basin
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Power Stations In Ethiopia
This page lists power stations in Ethiopia, both integrated with the national power grid but also isolated ones. Due to the quickly developing demand for electricity in Ethiopia, operational power plants are listed as well as those under construction and also proposed ones likely to be built within a number of years. Overview Due to favorable conditions in Ethiopia (water power, wind power, photovoltaics, geothermal energy) for power generation, the country avoids exploiting and importing fossil fuels as much as possible. As Ethiopia is a quickly developing country, the demand for electricity grows by 30% each year. This results in a very dynamic situation with many power plants being planned simultaneously or being under construction. In the year 2014 Ethiopia had – according to an estimation of the CIA – an annual electricity production of 9.5 TWh and was at position 101 worldwide. The total installed capacity was ~2,4 GWe, GWe (position 104). In July 2017, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tekezé River
The Tekezé River (; , originally meaning "river" in Ge’ez; , also spelled Takkaze; ), is a major river in Ethiopia. For part of its course it forms a section of the westernmost border of Ethiopia and Eritrea. The river is also known as the Setit () as it joins the Nile tributary Atbarah River just over the border in Sudan. According to materials published by the Ethiopian Central Statistical Agency (Ethiopia), Central Statistical Agency, the Tekezé River is long. The canyon which it has created is the deepest in Africa and one of the deepest in the world, at some points having a depth of over 2000 meters (6,562 feet).
