HVDC BorWin3 is a high voltage direct current (HVDC) link under construction to transmit offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 160 km. The project is the most recent of the German offshore HVDC projects to be awarded (in 2014). [1] It is being built by the Siemens/ Petrofac consortium with the offshore platform contract awarded to Drydocks World in Dubai. [2] The project is expected to be handed over to its owner, TenneT, in 2019. The project started power transmission in August 2019. [3] TenneT took control of operations in February 2020. [4]
A high-voltage, direct current (HVDC) electric power transmission system uses direct current (DC) for the transmission of electrical power, in contrast with the more common alternating current (AC) systems.
NorNed is a 580-kilometre (360 mi) long high-voltage direct current submarine power cable between Feda in Norway and the seaport of Eemshaven in the Netherlands, which interconnects both countries' electrical grids. It was once the longest submarine power cable in the world. Budgeted at €550 million, and completed at a cost of €600m, the NorNed cable is a bipolar HVDC link with a voltage of ±450 kV and a capacity of 700 MW. NorNed is a joint project of the Norwegian transmission system operator Statnett and its Dutch counterpart TenneT. The cable system itself and the two converter stations were produced by ABB.
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.
TenneT is a transmission system operator in the Netherlands and in a large part of Germany.
BARD Offshore 1 is a 400 megawatt (MW) North Sea offshore wind farm with 80 BARD 5.0 turbines. Since the owner could not buy such 5MW offshore wind turbines in sufficient numbers in 2006, Dr. Bekker set up its own production of turbines. This should serve as the legacy for his children. The systems were developed by aerodyn Energiesysteme GmbH. A plant for rotor blades and nacelle assembly was built in Emden and a plant for the offshore foundations in Cuxhaven. Two turbine prototypes were set up at the Rysumer Nacken in 2007, and another prototype in Hooksiel in 2008. Construction was finished in July 2013 and the wind farm was officially inaugurated in August 2013. The wind farm is located 100 kilometres (60 mi) northwest of the isle Borkum in 40-metre (130 ft) deep water.
Gode Wind 1, 2, and 3 are offshore wind farms located north-west of Norderney in the German sector of North Sea. They are owned by Ørsted. Gode Wind 1 and 2 are operational, while Gode Wind 3 is being developed.
HVDC BorWin1 is the first HVDC facility in the world to be built for importing power from an offshore wind park to shore, and the first to use voltage source converters (VSC) in Germany. It connects the offshore wind park BARD Offshore 1 and other offshore wind farms in Germany near Borkum to the European power grid. The facility was built by ABB and has a capacity of 400 MW at a bipolar voltage of ±150 kV. HVDC BorWin1, which leads from BorWin Alpha Offshore Platform to Diele substation, consists of a 75 kilometres (47 mi) of underground and 125 kilometres (78 mi) of submarine cable.

The project was completed and handed over to its owner, TenneT, in February 2015.
The Western HVDC Link is a high-voltage direct current (HVDC) undersea electrical link in the United Kingdom, between Hunterston in Western Scotland and Flintshire Bridge in North Wales, routed to the west of the Isle of Man. It has a transmission capacity of 2,200 MW and was expected to cost £1bn. The link entered operational service on 7 December 2017 at a reduced capacity of 900 MW pending further work at Hunterston. It entered full use on 16 October 2018.
HVDC BorWin2 is a high voltage direct current (HVDC) link built to transmit offshore wind power to the power grid of the German mainland.
