Landsvirkjun Power
Landsvirkjun, () the National Power Company of Iceland, is Iceland's largest electricity generator. Landsvirkjun operates 18 power plants in Iceland concentrated on five main areas of operation. History Landsvirkjun was founded on 1 July 1965 by the state of Iceland and the city of Reykjavík. The city of Reykjavík contributed to the company three power stations on the Sog (river), Sog River. Shortly after its founding construction on the Búrfell hydropower station began. From 1965 until 2005 the purpose of Landsvirkjun was to produce and distribute high voltage electricity. The Akureyri, municipality of Akureyri acquired a 5% share in Landsvirkjun in 1983 and became the third owner. Three hydropower stations on the Laxá River previously owned by the municipality of Akureyri were merged into Landsvirkjun. The hydropower stations Búrfell, Sigalda, Hrauneyjafoss, Blanda, Sultartangi, Vatnsfell Power Station, Vatnsfell, and Fljótsdalsstöð were all built by Landsvirkjun. The K ...

Búrfell Hydroelectric Power Station
The Búrfell hydroelectric power plant (Búrfellsstöð or Búrfellsvirkjun in Icelandic) is a run-of-river hydroelectric power plant located in the Þjórsá valley in southwest Iceland. It is operated by Landsvirkjun. It was, since its construction in 1969, until the construction of the Kárahnjúka power plant in 2008, the largest power plant in Iceland with a capacity of 270 MW (increased to 370 MW in 2018). It was mainly built to supply electricity to an aluminum factory located in Straumsvík, 3 km west of Hafnarfjörður. History The idea of harnessing the energy of the Þjórsá River at Búrfell Mountain was proposed in 1917. For two years, the Norwegian engineer Gotfred Sætersmoen conducted a study on the development of hydroelectricity in the Þjórsá region. He proposed five stations, Búrfell being by far the most important. In 1960, the project was seriously considered. A project of this magnitude could be economically very interesting if the electricity c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captive Insurance
Captive insurance is an alternative to self-insurance in which a parent group or groups create a licensed insurance company to provide coverage for itself. The main purpose of doing so is to avoid using traditional commercial insurance companies, which have volatile pricing and may not meet the specific needs of the company. By creating their own insurance company, the parent company can reduce their costs, insure difficult risks, have direct access to reinsurance markets, and increase cash flow. When a company creates a captive they are indirectly able to evaluate the risks of subsidiaries, write policies, set premiums and ultimately either return unused funds in the form of profits, or invest them for future claim payouts. Captive insurance companies sometimes insure the risks of the group's customers. This is an alternative form of risk management that is becoming a more practical and popular means through which companies can protect themselves financially while having more co ...

Kárahnjúkar Hydropower Plant
Kárahnjúkar Hydropower Plant ( is, Kárahnjúkavirkjun ), officially called Fljótsdalur Power Station ( is, Fljótsdalsstöð ) is a hydroelectric power plant in Fljótsdalshérað municipality in eastern Iceland, designed to produce annually for Alcoa's Fjarðaál aluminum smelter to the east in Reyðarfjörður. With the installed capacity of , the plant is the largest power plant in Iceland. The project, named after the nearby Kárahnjúkar mountains, involves damming the rivers Jökulsá á Dal and Jökulsá í Fljótsdal with five dams, creating three reservoirs. Water from the reservoirs is diverted through of underground water tunnels and down a vertical penstock towards a single underground power station. The smelter became fully operational in 2008 and the hydropower project was completed in 2009. The Kárahnjúkar Dam ( is, Kárahnjúkastífla ) is the centrepiece of the five dams and the largest of its type in Europe, standing tall with a length of and com ...

Capacity Factor
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production. The actual energy output during that period and the capacity factor vary greatly depending on a range of factors. The capacity factor can never exceed the availability factor, or uptime during the period. Uptime can be reduced due to, for example, reliability issues and maintenance, scheduled or unscheduled.

Wind Power In Iceland
Iceland is a world leader in renewable energy. 100% of Iceland's electricity grid is produced from renewable resources. In terms of total energy supply, 85% of the total primary energy supply in Iceland is derived from domestically produced renewable energy sources. Geothermal energy provided about 65% of primary energy in 2016, the share of hydropower was 20%, and the share of fossil fuels (mainly oil products for the transport sector) was 15%. The Icelandic government aspires that the nation will be carbon neutral by 2040. The largest obstacles to this are road transport and the fishing industry. In 2015, the total electricity consumption in Iceland was 18,798 GWh. Renewable energy provided almost 100% of production, with 75% coming from hydropower and 24% from geothermal power. Only two islands, Grimsey and Flatey, are not connected to the national grid and so rely primarily on diesel generators for electricity.

Geothermal Power In Iceland
Geothermal power in Iceland refers to the use of geothermal energy in Iceland for electricity generation. Iceland’s uniquely active geology has led to natural conditions especially suitable for harnessing geothermal energy. Icelanders have long used geothermal energy for direct applications, such as heating homes and baths. The more recent, widespread adoption of geothermal energy as an energy source in Iceland was spawned by a need to stabilize energy prices and increase energy independence, allowing Iceland to increase reliance on geothermal energy for direct applications alongside electricity generation and contributing significantly to diminishing Iceland’s carbon footprint. The growth of geothermal power in Iceland is due to its continued support from the Icelandic government. As of 2020, Iceland’s installed geothermal power production capacity is 799 megawatts (MW). Geothermal energy produces over a quarter of Iceland’s total electricity. Geology Iceland’s terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Krafla Geothermal Station
The Krafla geothermal power plant ( is, Kröflustöð ) is a geothermal power generating facility located in Iceland, close to the Krafla Volcano and the lake Mývatn. With 33 boreholes, it is considered to be Iceland's largest power station and it is able to produce 500 GWh of electricity annually, with an installed capacity of 60 megawatts. The construction work started in 1974, but due to volcanic activities in the area, building was slowed. The Krafla power station was officially launched in the early 1977, but was only able to produce at its full 60-megawatt capacity after a second steam turbine was installed in 1996. Originally the power plant was owned by the government, but was purchased in 1985 and has since been operated by Landsvirkjun (National Power Company). About 15 employees work there full-time.
