The North Germanic languages make up one of the three branches of the Germanic languages—a sub-family of the Indo-European languages—along with the West Germanic languages and the extinct East Germanic languages. The language group is also referred to as the Nordic languages, a direct translation of the most common term used among Danish, Faroese, Icelandic, Norwegian, and Swedish scholars and people.
The electricity sector in Norway relies predominantly on hydroelectricity. A significant share of the total electrical production is consumed by national industry.
Fortum Oyj is a Finnish state-owned energy company located in Espoo, Finland. It mainly focuses on the Nordic region. Fortum operates power plants, including co-generation plants, and generates and sells electricity and heat. The company also sells waste services such as recycling, reutilisation, final disposal solutions and soil remediation and environmental constructions services, and other energy-related services and products e.g. consultancy services for power plants and electric vehicle charging. Fortum is listed on the NASDAQ OMX Helsinki stock exchange.
Railway electrification using alternating current (AC) at 15 kilovolts (kV) and 16.7 hertz (Hz) are used on transport railways in Germany, Austria, Switzerland, Sweden, and Norway. The high voltage enables high power transmission with the lower frequency reducing the losses of the traction motors that were available at the beginning of the 20th century. Railway electrification in late 20th century tends to use 25 kV, 50 Hz AC systems which has become the preferred standard for new railway electrifications but extensions of the existing 15 kV networks are not completely unlikely. In particular, the Gotthard Base Tunnel still uses 15 kV, 16.7 Hz electrification.
Statnett is a Norwegian state owned enterprise responsible for owning, operating and constructing the stem power grid in Norway. The company has its headquarters in Oslo, Norway.
NASDAQ OMX Commodities Europe is a trade name of NASDAQ OMX Oslo ASA, the single financial energy market for Norway, Denmark, Sweden and Finland. Before 1 November 2010, it was known by the name Nord Pool. As of 2008, Nord Pool was the largest power derivatives exchange and the second largest exchange in European Union emission allowances (EUAs) and global certified emission reductions (CERs) trading.
NordLink is a subsea 1,400 megawatt (MW) HVDC power cable between Norway and Germany, opened in May 2021. The over 500 kilometres (310 mi) long cable operates at a voltage of 500 kV DC.
The synchronous grid of Continental Europe is the largest synchronous electrical grid in the world. It is interconnected as a single phase-locked 50 Hz mains frequency electricity grid that supplies over 400 million customers in 24 countries, including most of the European Union. In 2009, 667 GW of production capacity was connected to the grid, providing approximately 80 GW of operating reserve margin. The transmission system operators operating this grid formed the Union for the Coordination of Transmission of Electricity (UCTE), now part of the European Network of Transmission System Operators for Electricity (ENTSO-E).
Nordic electricity market is a common market for electricity in the Nordic countries. It is one of the first free electric-energy markets in Europe and is traded in NASDAQ OMX Commodities Europe and Nord Pool Spot. In 2003, the largest market shares were as follows: Vattenfall 17%, Fortum 14.1%, Statkraft 8.9%, E.on 7.5%, Elsam 5%, Pohjolan Voima 5%. Other producers had 42.5% market share.
Energinet is the Danish national transmission system operator for electricity and natural gas. It is an independent public enterprise owned by the Danish state under the Ministry of Climate and Energy. Energinet has some 1150 employees, and its headquarters are located in Erritsø near Fredericia in Jutland. The gas division is located in Ballerup near Copenhagen.
A wide area synchronous grid is a three-phase electric power grid that has regional scale or greater that operates at a synchronized utility frequency and is electrically tied together during normal system conditions. Also known as synchronous zones, the most powerful is the Northern Chinese State Grid with 1,700 gigawatts (GW) of generation capacity, while the widest region served is that of the IPS/UPS system serving most countries of the former Soviet Union. Synchronous grids with ample capacity facilitate electricity trading across wide areas. In the ENTSO-E in 2008, over 350,000 megawatt hours were sold per day on the European Energy Exchange (EEX).
The IPS/UPS is a wide area synchronous transmission grid of some CIS countries, with a common mode of operation and centralized supervisory control. It has an installed generation capacity of 300 gigawatts, and produces 1,200 terawatt-hours (TWh) per year for its 280 million customers. The system spans eight time zones.
The Great Belt power link, also known as the Great Belt electricity link, is a high-voltage direct-current interconnection across the Great Belt between Funen and Zealand connecting two power transmission systems in Denmark.
The Nordic countries are a geographical and cultural region in Northern Europe and the North Atlantic. It includes the sovereign states of Denmark, Finland, Iceland, Norway and Sweden; the autonomous territories of the Faroe Islands and Greenland; and the autonomous region of Åland.
The North Seas Energy Cooperation (NSEC) officially the Political Declaration on energy cooperation between the North Seas Countries previously the, North Seas Countries Offshore Grid Initiative (NSCOGI), is a collaboration between EU member-states and Norway to create an integrated offshore energy grid which links wind farms and other renewable energy sources across the northern seas of Europe. It is one of several proposed European super grid schemes.
Nord Pool AS is a pan-European power exchange. Nord Pool has a main office in Oslo and further offices in Stockholm, Helsinki, Tallinn, Berlin and London. The company is owned by the European exchange operator Euronext as well as TSO Holding, which represents the continental Nordic and Baltic countries' transmission system operators. Nord Pool has two subsidiaries, Nord Pool AB and Nord Pool Finland Oy.
Majority of electricity production in Sweden relies on hydro power and nuclear power. In 2008 the consumption of electricity in Sweden was 16018 kWh per capita, compared to EU average 7409 kWh per capita. Sweden has a national grid, which is part of the Synchronous grid of Northern Europe. A specialty of the Nordic energy market is the existence of so-called electricity price areas, which complicate the wholesale Nordic energy market.
Denmark's western electrical grid is part of the Synchronous grid of Continental Europe whereas the eastern part is connected to the Synchronous grid of Northern Europe via Sweden.
Litgrid AB is a Lithuanian electricity transmission system operator that operates Lithuania's electricity transmission grid. Litgrid is responsible for the integration of the Lithuanian electricity system into the European electricity infrastructure and the common electricity market.
Harmony Link is a planned submarine power cable between Lithuania and Poland. The purpose of the cable is to finish the transition of the Baltic states from IPS/UPS to the synchronous grid of Continental Europe.
