Melkefoss Hydroelectric Station
Melkefoss power station is a hydro electric dam on the Paatsjoki river in the Sør-Varanger municipality in Finnmark, Norway. The power station, which is owned by Pasvik Kraft, makes use of a fall of 10 meters in the river. Although the power station is located on a river, Lake Inari is regulated as storage for all of the power stations in the drainage basin A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, t .... The dam has one installed Kaplan turbine, yielding 26 Megawatts. Mean yearly production at the dam is 129 Gigawatt hours.

Paatsjoki
The Paatsjoki River ( fi, Paatsjoki, sms, Paaččjokk, sme, Báhčaveaijohka, no, Pasvikelva, sv, Pasvik älv, russian: Паз or Патсойоки, ''Paz or Patsoyoki'') is a river that flows through Finland, Norway, and Russia. Since 1826, the river has marked parts of the Norway–Russia border, except from 1920 to 1944 when it was along the Finland–Norway border. The river is the outlet from the large Lake Inari in Finland and flows through Norway and Russia to discharge into the Bøkfjorden (which later flows into the Varangerfjorden and then the Barents Sea), not far from the town of Kirkenes. The river has a watershed of , and is long. A series of hydroelectric stations, known as the Paatsjoki River Hydroelectric Plants, are along the river. The river provides good fishing opportunities for Atlantic salmon The Atlantic salmon (''Salmo salar'') is a species of ray-finned fish in the family Salmonidae. It is the third largest of the Salmonidae, behind Siber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Finnmark
Finnmark (; se, Finnmárku ; fkv, Finmarku; fi, Ruija ; russian: Финнмарк) was a county in the northern part of Norway, and it is scheduled to become a county again in 2024. On 1 January 2020, Finnmark was merged with the neighbouring county of Troms to form the new Troms og Finnmark county. On 1 January 2024, the county will be demerged back to the counties Finnmark and Troms, after a decision made by parliament on 15 June 2022. By land, it bordered Troms county to the west, Finland ( Lapland region) to the south, and Russia (Murmansk Oblast) to the east, and by water, the Norwegian Sea (Atlantic Ocean) to the northwest, and the Barents Sea (Arctic Ocean) to the north and northeast. The county was formerly known as ''Finmarkens amt'' or ''Vardøhus amt''. Starting in 2002, it had two official names: Finnmark (Norwegian) and Finnmárku (Northern Sami). It was part of the Sápmi region, which spans four countries, as well as the Barents Region, and is the largest and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norway
Norway, officially the Kingdom of Norway, is a Nordic country in Northern Europe, the mainland territory of which comprises the western and northernmost portion of the Scandinavian Peninsula. The remote Arctic island of Jan Mayen and the archipelago of Svalbard also form part of Norway.

It is bordered by Finland and Russia to the northeast and the Skagerrak strait to the south, on the other side of which are Denmark and the United Kingdom. Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. The maritime influence dominates Norway's climate, with mild lowland temperatures on the se ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

Lake Inari
Lake Inari ( fi, Inarijärvi/Inarinjärvi, se, Anárjávri, smn, Aanaarjävri, sms, Aanarjäuʹrr, sv, Enare träsk, no, Enaresjøen) is the largest lake in Sápmi and the third-largest lake in Finland. It is located in the northern part of Lapland, north of the Arctic Circle. The lake is above sea level, and is regulated at the Kaitakoski power plant in Russia. The freezing period normally extends from November to early June. The best-known islands of the lake are Hautuumaasaari ("Graveyard Island"), which served as a cemetery for ancient Sami people, and Ukonkivi ("Ukko's Stone"), a sacrificial place of the ancient inhabitants of the area. There are over 3,000 islands in total. Trout, lake salmon, Arctic char, white fish, grayling, perch and pike are found in Lake Inari. The lake covers . It empties northwards through the Paatsjoki at the mouth of the Varangerfjord, which is a bay of the Barents Sea. The lake depression is a graben bounded by faults active in the Cen ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. But t ...

Megawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own 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, the rate at which 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 potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \mathr ...
