Bayreuth/Berlin, 17 January 2022 –Transmission system operators 50Hertz and TenneT are planning to collectively transport wind energy from the North Sea into the German energy grid. The 2 firms have signed a cooperation to understand an progressive multi-terminal hub within the space of Heide (Schleswig-Holstein) and an extra-high voltage direct present hyperlink (HVDC) to Mecklenburg-Vorpommern. The challenge is a part of the 2035 grid improvement plan (2021) confirmed by the Fed-eral Bundesnetzagentur (BNetzA).
Stefan Kapferer, 50Hertz CEO: “If Germany is to grow to be climate-neutral by 2045, there should be much more concentrate on cooperation sooner or later. 50Hertz and TenneT are due to this fact working collectively and becoming a member of forces to deal with this difficult challenge so as to transport as a lot electrical energy generated at sea as shortly as doable to the place it will likely be urgently wanted sooner or later.”
Tim Meyerjürgens, COO of TenneT: “With the joint implementation of the onshore hub in Schleswig-Holstein, TenneT and 50Hertz are laying the inspiration for even greater utilisation of onshore DC strains whereas on the similar time rising the extent of safety of provide. As well as, the idea permits to speed up the growth of offshore wind power, as envisaged by the brand new German authorities. With the implementation of the onshore hub and the three grid growth tasks linked to it, it will likely be doable to attach 4 gigawatts of offshore wind power from the North Sea within the space of Heide as early as 2032. Which means that one a part of the challenge will likely be accomplished three years and one other even 5 years sooner than initially deliberate within the grid improvement plan.”
The joint challenge of the 2 firms consists of a number of elements: Within the space of Heide, 50Hertz and TenneT need to construct the onshore multi-terminal hub for a number of direct present connections. It consists of an progressive direct present switchgear. This development permits the direct and space-saving connection of two offshore direct present connection techniques, every with a capability of two gigawatts, with an onshore direct present hyperlink. As well as, a converter is related to this plant, which converts direct present (DC) into alternating present (AC), which is then accessible within the area for deliberate offshore hydrogen electrolysers to decarbonize the business positioned there, amongst different issues. The converter will also be used to allow the transport of electrical energy generated by onshore wind generators.
Between this multi-terminal hub and a converter within the space of Klein Rogahn close to Schwerin, 50Hertz and TenneT plan to put a direct-current underground cable round 200 kilometres lengthy that may transmit electrical energy on the 525 kilovolt (kV) voltage degree. 50Hertz will likely be answerable for the japanese part and TenneT for the western one.
The 2 offshore grid connection techniques for the world of Heide confirmed within the simply revealed grid improvement plan (Netzentwicklungsplan 2035 / 2021) will likely be applied individually: the NOR-12-2 system will likely be related to the multi-terminal-hub by 50Hertz and the NOR-X-3 sys-tem by TenneT.
Technically, the multi-terminal hub resolution is an innovation as to this point, direct present connec-tions at sea and on land have been realised as pure point-to-point connections. Within the multi-terminal hub, nonetheless, a number of direct present connections converge. The electrical energy is fed into the transmission grid by way of DC or AC strains in keeping with the corresponding transmission capacities and demand conditions. Subsequently, not three however just one AC/DC converter station must be constructed within the Heide space. This reduces prices and land consumption on web site – and moreover helps to make load flows extra versatile.
