Germany, Berlin: This is the largest offshore grid connection order in the history of Siemens Energy.
Two new power links set the course for more wind energy in the German power grid: DolWin4 and BorWin4 will transport up to 1.8 GW of green wind power from several wind farms in the German North Sea to land with low losses. As a result, they will be able to meet the demand of a major city like Hamburg with 1.8 million inhabitants. Amprion Offshore GmbH has now commissioned Siemens Energy to supply the necessary technology for the converter stations of their first grid connection projects. The order value is in the high three-digit million-euro range, making it the largest offshore grid connection order the company has received to date.
“The share of renewable energies in Germany’s power supply is set to rise to 80 percent by 2030. Therefore, building new wind power plants is important but ultimately pointless if the energy does not reach consumers. We also need to invest in our power grid to supply the country with sustainable energy reliably,” says Tim Holt, member of the Managing Board at Siemens Energy.
Since the transmission grid in the coastal region of Lower Saxony is already heavily utilized by numerous wind farms, the connection points for the links are located far inland. The land converter stations will be built near Amprion’s Hanekenfähr substation in Lingen in southern Emsland. The grid hub currently connects the Emsland nuclear power plant to the transmission grid, which is scheduled to be shut down at the end of 2022. DolWin4 and BorWin4 will replace the generation capacity, thus eliminated with 1.8 GW of offshore wind energy.
In addition to supplying the technology, Siemens Energy will also take over the complete maintenance of the converter solutions for an initial period of 10 years. All high-voltage equipment for the two connection systems, such as converter technology, transformers, and switchgear, will be manufactured by Siemens Energy in Europe. The Spanish consortium partner Dragados Offshore S.A. (a subsidiary of the VINCI Group) is responsible for the design, construction, and offshore installation of the associated platforms. Construction will take place at the company’s yard in Cádiz, Spain.
Nine of the current 15 HVDC grid connection projects in the German North Sea use Siemens Energy technology. Meanwhile, the United Kingdom wants to generate enough green energy through offshore wind by 2030 to supply every household in the country with electricity. The United Kingdom recently gave the go-ahead for five more offshore wind farm projects in the largest ever round of contracts for difference. According to the operators’ current plans, four of these projects will be equipped with grid connection systems from Siemens Energy. Most recently, Siemens Energy booked the order for the grid connection of the East Anglia Three offshore wind farm in July. After commissioning, the 1.4 GW wind farm is expected to supply around one million households with green electricity.
