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 National Grid is the high-voltage electric power transmission network serving Great Britain, connecting power stations and major substations, and ensuring that electricity generated anywhere on the grid can be used to satisfy demand elsewhere. The network serves the majority of Great Britain and some of the surrounding islands. It does not cover Northern Ireland, which is part of the Irish single electricity market.
SwePol is a 254.05-kilometre (157.86 mi)-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.
A submarine power cable is a transmission cable for carrying electric power below the surface of the water. These are called "submarine" because they usually carry electric power beneath salt water but it is also possible to use submarine power cables beneath fresh water. Examples of the latter exist that connect the mainland with large islands in the St. Lawrence River.
National Grid plc is a British multinational electricity and gas utility company headquartered in London, England. Its principal activities are in the United Kingdom, where it owns and operates electricity and natural gas transmission networks, and in the Northeastern United States, where as well as operating transmission networks, the company produces and supplies electricity and gas, providing both to customers in New York and Massachusetts.
EirGrid plc is the state-owned electric power transmission operator in Ireland. It is a public limited company registered under the Companies Acts; its shares are held by the Minister for the Environment, Climate and Communications. It is one of a number of Irish state-sponsored bodies and is regulated by the Commission for Regulation of Utilities.
NordBalt 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.
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.
Ignitis Group is a state-owned energy holding company located in Vilnius, Lithuania. The Group’s core business is focused on operating Lithuania’s electricity distribution network (Networks) and managing and developing its Green Generation Portfolio. The Group also manages strategically important reserve capacities and provides services to its customers, including the supply of electricity and natural gas, solar, e-mobility, energy efficiency and innovative energy solutions for private and business customers.
Rail transport in Lithuania consists of freight shipments and passenger services. The construction of the first railway line in Lithuania began in 1859. As of 2021, the total length of railways in Lithuania was 1,868.8 km (1,161.2 mi). Lietuvos Geležinkeliai, the national state-owned railway company, operates most of the passenger and freight services.
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).
TenneT is a transmission system operator in the Netherlands and in a large part of Germany.
Lithuania is a net energy importer. In 2019 Lithuania used around 11.4 TWh of electricity after producing just 3.6 TWh.
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.
Vilnius – Klaipėda Railway is one of the main local railways in Lithuania. This railway connects the Lithuanian capital Vilnius with the country's biggest seaside city Klaipėda. It is the most actively used train line in Lithuania.
Gas Interconnection Poland–Lithuania (GIPL) is a gas pipeline between Poland and Lithuania. The pipeline was commissioned and started commercial operation on 1 May 2022. The length of the pipeline is 508 km (316 mi) and the natural gas can flow both directions. The pipeline will run from Jauniūnai natural gas compression station (GCS) in eastern Lithuania to the Hołowczyce GCS station in eastern Poland.
Viking Link is a 1,400 MW HVDC submarine power cable between the United Kingdom and Denmark completed in 2023.
Gridlink Interconnector is a proposed submarine power cable between England and France. The 1,400 MW high-voltage direct current connector would link Kingsnorth National Grid substation in north Kent, England, with Réseau de Transport d'Électricité Warande substation in Bourbourg (Nord) near Dunkirk in northern France.
Baltic states synchronization with UCTE is an international electricity transmission infrastructure project to synchronize the three Baltic states with the Synchronous grid of Continental Europe, managed by ENTSO-E, and leave the IPS/UPS transmission system managed by the BRELL agreement. The project is expected to be completed by February 2025.
