SwePol
SwePol is a -long monopolar high-voltage direct current (HVDC) submarine cable between the Stärnö peninsula near Karlshamn, Sweden, and Bruskowo Wielkie, near Słupsk, Poland. The link was inaugurated in 2000 and can transmit up to 600 MW power at a voltage of 450 kV. The cable has a cross section of . It runs for as an underground cable from the Stärno HVDC Station to the shore of the Baltic Sea. The long submarine cable comes ashore in Poland near Ustka at and runs underground for the remaining to Bruskowo Wielkie HVDC Static Inverter Plant. Unlike other monopolar HVDC schemes, Swepol uses a metallic return consisting of 2 cables with sections for the submarine portion of the line, and a single cable with sections for the land portions. Both stations use air-core inductance smoothing rectifiers of 225 mH and a weight of , with filters for the 11th, 13th, 24th, and 36th harmonics. Each filter consists of a coil and a capacitor switched in row. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stärnö Power Station
Karlshamn Power Station (also known as Stärnö Power Station, sv, Karlshamnsverket) is an oil-fired thermal power station on Stärnö peninsula west of Karlshamn. It has had three units, each with a generation capacity of 340 MW, which went in service in 1969, 1971 and 1973. Unit 1 was closed in 2015. Each unit has its own tall flue gas stack A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air.

2022 Nord Stream Pipeline Sabotage
The 2022 Nord Stream pipeline sabotage consisted of a series of clandestine bombings and subsequent underwater gas leaks that occurred on the Nord Stream 1 and Nord Stream 2 natural gas pipelines on 26 September 2022. The sabotage happened as the Baltic Pipe was being opened for natural gas to come in from the North Sea through Denmark to Poland; however, the perpetrators' identities and the motives behind the sabotage remain debated. Both pipeline pairs were built to transport natural gas from Russia to Germany through the Baltic Sea, and are majority owned by the Russian majority state-owned gas company, Gazprom. Prior to the leaks, the pipelines had not been operating due to disputes between Russia and the European Union in the wake of the Russian invasion of Ukraine but were filled with natural gas. On 26 September at 02:03 local time (CEST), an explosion was detected originating from Nord Stream 2; a pressure drop in the pipeline was reported and natural gas began escapin ...

Estlink
Estlink is a set of HVDC submarine power cables between Estonia and Finland. Estlink 1 is the first interconnection between the Baltic and Nordic electricity markets followed by Estlink 2 in 2014. The main purpose of the Estlink connection is to secure power supply in both regions to integrate the Baltic and Nordic energy markets. Estlink 1 History First plans for a submarine power cable between the Baltic and the Nordic regions were proposed in 1990s. Negotiations between Eesti Energia, Pohjolan Voima, Helsingin Energia, Graninge (now E.ON Sverige), Latvenergo, Statkraft and TXE Nordic Energy, a subsidiary of TXU (now Energy Future Holdings Corporation) started In 1999, and on 9 October 2001 a contract was signed in Tallinn. However, only after the harsh winter of 2002–2003 which resulted in an increased demand for power, the project of the submarine cable between Estonia and Finland got a boost. The letter of intention for underwater sea cable was signed between E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LitPol Link
LitPol Link is an electricity link between Poland and Lithuania which connects the Baltic transmission system to the synchronous grid of Continental Europe. It has a capacity of 500 MW and since 2021 it can operate in a synchronous regime. History In 2000, European Commission and the EBRD agreed to finance a feasibility study on the Poland–Lithuania transmission interconnection. The study was completed in September 2002. The connection is expected to increase Poland's electricity interconnection level from 2% to 4%. Parts of LitPol are on the EU "Projects of Common Interest" list in November 2015. On 29 September 2006 Polish President Lech Kaczyński and Lithuanian President Valdas Adamkus signed a joint declaration on the joint power grid project during their meeting in Warsaw. The memorandum of understanding to establish a joint interconnection operator was signed between Lietuvos Energija and Polish PSE-Operator in Vilnius on 8 December 2006.

NordBalt
NordBalt (also formerly known as SwedLit) is a submarine power cable between Klaipėda in Lithuania and Nybro in Sweden. The purpose of the cable is to facilitate the trading of power between the Baltic and Nordic electricity markets, and to increase the supply and energy security in both markets. History The project was originally suggested in 2004. Original project Swindlit was aimed at construction of the wind farm in the Baltic Sea and ensuring the electricity transmission to Sweden and Lithuania. The participants of this project were interested also in Kruonis Pumped Storage Plant as an accumulator of variable wind energy. In August 2006, the Lithuanian and Swedish transmission grid operators Lietuvos Energija and Svenska kraftnät agreed to launch a feasibility study of a possible interconnector. In February 2007, Lietuvos Energija and Svenska Kraftnät signed an agreement with Swedish consulting company SWECO International on preparation of feasibility study. The study ...

Karlshamn
Karlshamn () is a locality and the seat of Karlshamn Municipality in Blekinge County, Sweden. It had 13,576 inhabitants in 2015, out of 31,846 in the municipality. Karlshamn received a Royal Charter and city privileges in 1664, when King Charles X Gustav, in Swedish Karl, realized the strategic location near the Baltic Sea. In 1666 the town was named Karlshamn, meaning ''Karl's Port'' in honour of the Swedish king. History At the outlet of the stream Mieån was found a harbour and fishing village "Bodekull" and a farm "Bodetorp". In the lower parts of "Mörrumsån" was a prosperous salmon fishery. Sweden gained supremacy over the territory through Treaty of Roskilde 1658. The king Charles X Gustav immediately inspected the coast and found here a tremendously beautiful and incomparable harbour. Fortifications designed by Erik Dahlberg were erected on Boön 1659 and on Friesholmen 1675, called "Kastellet". Troops loyal to the Danish king attacked the town twice in 1676–78. T ...

Baltic Cable
The Baltic Cable is a monopolar HVDC power line running beneath the Baltic Sea that interconnects the electric power grids of Germany and Sweden. Its maximum transmission power is 600 megawatts (MW). The Baltic Cable uses a transmission voltage of 450 kV – the highest operating voltage for energy transmission in Germany. The total project cost was 2 billion SEK (US$280 million), and the link was put into operation in December 1994. With a length of , it was the second longest high voltage undersea cable on earth, until Basslink came into service in 2006. Route The Baltic Cable starts in Germany at the converter station at Lübeck-Herrenwyk, which is on the site of a former coal-fired power station, It crosses the river Trave in a channel below the bottom of the river and then follows its course as sea cable laid at the eastern side of the river. After crossing the Priwall Peninsula the cable runs parallel to the coast of Mecklenburg-Vorpommern, befor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Interconnectors To And From The Nordic Grid
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...
