Tekezé Dam
Tekezé Dam is a double-curvature arch dam located between Amhara and Tigray region 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 * Water politics in the Nile Basin A ...

Arch Dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The developme ...

Energy In Ethiopia
Energy in Ethiopia is energy and electricity production, consumption, transport, exportation, and importation in Ethiopia. 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 secondary energy sector, with the construction of mainly hydropower plants and power transmission lines being most visible. * PE: Ethiopia did not export PE in the years shown. * PE: all PE imports were ''bituminous materials'' (natural asphalt used as engineering material for the ...

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] |
Water Politics In The Nile Basin
As a body of water that crosses numerous international political borders, the Nile river is subject to multiple political interactions. Traditionally it is seen as the world's longest river flowing 6,700 kilometers through ten countries in northeastern Africa – Rwanda, Burundi, Democratic Republic of the Congo (DRC), Tanzania, Kenya, Uganda, Ethiopia, South Sudan, Sudan and Egypt with varying climates. Considering the basin area of the Nile, Sudan has the largest size (1.9 million km²) whereas, of the four major tributaries to the Nile, three originate from Ethiopia – the Blue Nile, Sobat and Atbara. The modern history of hydropolitics in the Nile basin is very complex and has had wide ramifications both for regional and global developments.

Dams Completed In 2009
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 earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
