Sangtuda 1 Hydroelectric Power Plant
Sangtuda 1 Hydroelectric Power Plant (russian: Сангтудинская ГЭС-1; tg, Нерӯгоҳи барқи обии Сангтӯда-1) is a hydroelectric power plant, located on the Vakhsh River in Tajikistan. Construction commenced during the Soviet period in the 1980s, but halted in the beginning of the 1990s due to lack of financing when the station was about 20% complete. An agreement with Russia allowed to restart the construction, with four units entering service in 2008–2009. The plant was officially commissioned on 31 July 2009. Once working at full capacity, the plant will provide around 12% of Tajikistan's electricity output. History Plans to build the power plant were made during the 1970s, with the actual construction commencing in 1989. Dissolution of the Soviet Union, the resulting halt of financing, as well as the Civil War in Tajikistan interrupted the construction for over a decade. In 1996, the government set up a company for the constructi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khatlon Region
Khatlon Region ( tg, Вилояти Хатлон, ''Viloyati Xatlon''), one of the four provinces of Tajikistan ( tg, вилоят, ''Viloyat''), is the most populous of the four first level administrative regions. It is situated in the southwest of the country, between the Hisor (Gissar) Range in the north and the river Panj in the south and borders on Afghanistan in the southeast and on Uzbekistan in the west. During Soviet times, Khatlon was divided into Kurgan-Tyube (Qurghonteppa) Oblast (Western Khatlon) – with the Kofarnihon and Vakhsh river valleys – and Kulob Oblast (Eastern Khatlon) – with the Kyzylsu and Yakhsu river valleys. Both regions were merged in November 1992 into today's Khatlon Region (or ''viloyat''/''oblast''). The capital city is Bokhtar, formerly known as ''Qurghonteppa'' and ''Kurgan-Tyube''. Khatlon has an area of 24,700 square kilometres and consists of 21 districts and 4 district-level cities. The total population of Khatlon in ...

Energy Infrastructure Completed In 2011
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Dams On The Vakhsh River
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 used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectric Power Stations In Tajikistan
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Run-of-river
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture. Concept Run-of-the-river, or ROR, hydroelectricity is considered ideal for streams or rivers that can sustain a minimum flow or those regulated by a lake or reservoir upstream. A small dam is usually built to create a headpond ensuring that there is enough water entering the penstock pipes that lead to the turbines, which are at a lower elevation. Projects with pondage, as opposed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Fill Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
