Buksefjord Hydroelectric Power Plant
The Buksefjord hydroelectric power plant is the first and largest hydroelectric power plant in Greenland. It was built by Nuuk-Kraft and it is operated by Nukissiorfiit, Greenland's national energy company. In 1984–85, Greenland's energy authority prepared a Greenland's hydroelectricity development program. At that time all electricity in Greenland was produced by oil based fuels, but there had been a sharp rise in the oil prices the preceding years. Construction of a plant in Buksefjord was proposed by a private consortium in 1988. In 1989, four companies were invited to a public tender. However, later it was decided that construction of the plant will be financed by the Home Rule of Greenland and the plant will be rented to Nuuk-Kraft consortium. Construction of the plant was approved by the Parliament of Greenland in 1990. It was commissioned in 1993. Unconventionally, the power station is situated inside a mountain and it consists of of tunnels. The upper reservoir, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Nukissiorfiit
Nukissiorfiit is a government-owned Greenland energy company. Nukissiorfiit means "where energies are created". The company supplies most of Greenland with electricity, water and heat. Most of the electricity is produced by hydro power such as the Qorlortorsuaq Dam. 70% of Greenland's energy is produced by renewable sources. The rest is produced by oil burned plants. The company employs 400 people, spread on 17 cities and 54 villages. There is a lot of potential yet unbuilt hydro power. However the rugged terrain, the fjords and the usually short distance between the ice sheet and fjords means there are many short small rivers, meaning benefit per power plant is smaller. A port and a road must be built for each one. In the winter rivers are frozen, so dams are needed to create water flow during winter. Sometimes power lines must cross fjords with spans like the Ameralik Span The Ameralik Span is the longest span of an electrical overhead power line in the world. It is situated ne ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Parliament Of Greenland
The Inatsisartut ( kl, Inatsisartut; '' da, Landstinget, lit=''the land's- thing'' of Greenland''), also known as the Parliament of Greenland in English, is the unicameral parliament (legislative branch) of Greenland, an autonomous territory* * * in the Danish realm. Established in 1979, it meets in Inatsisartut, on the islet of Nuuk Center in central Nuuk. There are 31 members, who are elected for four-year periods by proportional representation. History of the parliament The Parliament of Greenland succeeded the provincial council ( da, Grønlands Landsråd) on 1 May 1979. The parliament is led by a presidency comprising four members of the parliament, and the chairman. There are 31 members in the assembly. Speaker The speaker is the presiding officer of the Inatsisartut. The speaker determines which members may speak, and is responsible for maintaining order. On October 3, 2018, Siumut had Vivian Motzfeldt, the outgoing Foreign Minister, elected. On the 16th of April ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sermitsiaq (newspaper)
''Sermitsiaq'' is one of two national newspapers in Greenland. It is named after the mountain Sermitsiaq. The newspaper was published for the first time May 21, 1958, as a Kalaallisut-language alternative to the Danish-language newspaper ''Mikken''. The two magazines were printed separately, with Mikken on Saturdays and Sermitsiaq on Mondays for about six months, until Mikken was published for the last time on 22 November the same year. ''Sermitsiaq'' was first printed in both Danish and Kalaallisut the week before ''Mikken'' closed down. ''Sermitsiaq'' was a local newspaper distributed only in Nuuk city until around 1980 when the newspaper became national. The newspaper became increasingly political in the period around 1980, since Greenland was granted home rule in 1979. The newspaper is published every Friday, while the online version is updated several times daily. In 2010 ''Sermitsiaq'' merged with ''Atuagagdliutit/Grønlandsposten ''Atuagagdliutit/Grønlandsposten'', u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuuk
Nuuk (; da, Nuuk, formerly ) is the capital and largest city of Greenland, a constituent country of the Kingdom of Denmark. Nuuk is the seat of government and the country's largest cultural and economic centre. The major cities from other countries closest to the capital are Iqaluit and St. John's in Canada and Reykjavík in Iceland. Nuuk contains a third of Greenland's population and its tallest building. Nuuk is also the seat of government for the Sermersooq municipality. In January 2021, it had a population of 18,800. The city was founded in 1728 by the Dano-Norwegian missionary Hans Egede when he relocated from the earlier Hope Colony () where he arrived in 1721. The governor Claus Paarss was part of the relocation. The new colony was placed at the Inuit settlement of Nûk and was named ''Godthaab'' ("Good Hope"). "Nuuk" is the Greenlandic word for "cape" ( da, næs) and is commonly found in Greenlandic place names. It is so named because of its position at the end of t ...

Ameralik Span
The Ameralik Span is the longest span of an electrical overhead power line in the world. It is situated near Nuuk on Greenland and crosses Ameralik Fjord with a span width of at . It was built in 1993 by the Norwegian company NTE Entreprise (Nord-Trøndelag Elektrisitetsverk) and is part of a single-circuit 132 kV powerline running from Buksefjord hydroelectric power plant to Nuuk. The span consists of four steel conductors of 40 millimeters diameter whereby one is a spare conductor. The span has a width of 190 metres and a minimum clearance of 128 metres. The pylons on each side of the span carry only one conductor each and are situated on mountains 444 metres high on the north and 1,013 metres at the south shore. It is designed to withstand the cold winters of Greenland, so electricity produced can reach consumers without any disturbance.

List Of Spans
The following is a list of spans, either used for overhead line crossings of rivers, sea straits or valleys, as antenna or for aerial tramways. Powerline spans in flat areas with high pylons At these spans the sag of the conductors is less than the height of the pylons Powerline spans in mountainous areas requiring shorter pylons At these spans, the pylons are situated on the tops of mountains, so the topography determines the height of the lines. Because of this it is possible that the span pylons can be lower than the height of the line at point of largest sag. Antenna spans across valleys Aerial tramways Rope Tyroleans Other See also * Architectural structure Architectural engineers apply and theoretical knowledge to the engineering design of buildings and building systems. The goal is to engineer high performance buildings that are sustainable, economically viable and ensure the safety health. Archi ... * Timeline of three longest spans Referenc ...

Hydroelectric Power Stations In Greenland
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.
