Sevan–Hrazdan Cascade
Sevan–Hrazdan Cascade () is a complex of hydroelectric power plants on the Hrazdan River and its tributaries between the Lake Sevan and Yerevan in Armenia. They use irrigation water flow from the Lake Sevan and streams waters of Hrazdan River. The cascade is owned by the International Energy Corporation (IEC), a subsidiary of Tashir Group owned by Samvel Karapetyan. History The first small-scale Yerevan Hydroelectric Power Plant (HPP) was built in 1923. In 1932, it was replaced by Yerevan-2 HPS. The construction of the current cascade started in 1936, when the Kanaker HPS was opened. That time it was planned to built the whole cascade by 1947. In 1940, construction of the Sevan HPS started but due to World War II, construction was suspended and the HPS became operational only in 1949. The largest HPS, Argel HPS, was opened in 1953, followed by Arzni HPS in 1953, Yerevan-3 HPS in 1955, Hrazdan HPS in 1959 and Yerevan-1 HPS in 1962. The original plan included also constructi ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Dams In Armenia
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 Armenia
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.

Energy In Armenia
Energy in Armenia is mostly from natural gas. Armenia has no proven reserves of oil or natural gas and currently imports most of its gas from Russia. The Iran-Armenia Natural Gas Pipeline has the capacity to equal imports from Russia. Despite a lack of fossil fuel, Armenia has significant domestic electricity generation resources. The Armenian electrical energy sector has had a surplus capacity ever since emerging from a severe post-Soviet crisis in the mid-1990s thanks to the reopening of the nuclear power station at Metsamor."New Armenian Power Plant Set For Launch" Armenia Liberty (), December 21, 2010.

USAID
The United States Agency for International Development (USAID) is an independent agency of the U.S. federal government that is primarily responsible for administering civilian foreign aid and development assistance. With a budget of over $27 billion, USAID is one of the largest official aid agencies in the world and accounts for more than half of all U.S. foreign assistance—the highest in the world in absolute dollar terms. Congress passed the Foreign Assistance Act on September 4, 1961, which reorganized U.S. foreign assistance programs and mandated the creation of an agency to administer economic aid. USAID was subsequently established by the executive order of President John F. Kennedy, who sought to unite several existing foreign assistance organizations and programs under one agency. USAID became the first U.S. foreign assistance organization whose primary focus was long-term socioeconomic development. USAID's programs are authorized by Congress in the Foreign Assistanc ...

Metsamor Nuclear Power Plant
The Armenian Nuclear Power Plant (ANPP) (), also known as the Metsamor Nuclear Power Plant, (Armenian: Մեծամորի ատոմային էլեկտրակայան) is the only nuclear power plant in the South Caucasus, located 36 kilometers west of Yerevan in Armenia. The ANPP complex consists of two VVER-440 Model V270 nuclear reactors, each capable of generating 407.5 megawatts (MW) of power, for a total of 815 MW. The plant supplied approximately 40 percent of Armenia's electricity in 2015. As with other early VVER-440 plants, and unlike Western pressurized water reactors (PWR), the ANPP lacks a secondary containment building. History The ANPP complex consists of two units. The first unit was activated on 22 December 1976, and the second on 5 January 1980. Following public pressure after the Spitak Earthquake in 1988, the Council of Ministers of the Soviet Union decided to shut down the existing two units. After the fall of the USSR, Armenia had a period of energy scarci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
