Siemens Energy has won an order for the converter stations for the electrical grid of the Amprion Offshore wind farms in Germany. Includes two connections, DolWin4 y BorWin4, both located in the North Sea. The order has a three-digit value of millions of euros. This is the largest order the company has received to date for the offshore grid connection.
Siemens Energy's scope of supply includes offshore converter station platforms, ground converter stations and high-voltage direct current transmission cables (cables HVDC) for electricity transmission. This will help offshore wind farms transmit green power with low line losses..
Offshore converter platform converts AC power generated by wind turbines into DC power. Next, DC current is transmitted through high voltage direct current transmission cables. Finally, a converter station on land converts electricity into AC. It is known that the DolWin4 project will cover a distance of 215 km and the BorWin4 project a distance of 280 km.
the two connections, DolWin4 y BorWin4, will be installed in parallel and are expected to come into operation in 2028.
From the North Sea wind farms, the cables will initially run between 60 Y 125 kilometers out to sea, passing under the island of Norderney. And they will reach the coast in the Hilgenriedersiel region. From there, others will travel 155 kilometers in the form of underground cables to the Hanekenfähr substation, and Lingen.
From there, Amprion will connect them to your transmission network. The center of the network is currently connected to the nuclear power plant of Emsland nuclear power plant. Its closure is scheduled for the end of 2022. DolWin4 and BorWin4 will replace their generation capacity.
From various wind farms in the German North Sea they will supply up to 1,8 GW of electricity to ground. With this network connection, wind farms will be able to meet the needs of a big city like Hamburg, con 1,8 millions of inhabitants.
In addition to providing the technology, Siemens Energy will also take care of the complete maintenance of the converter station solution for an initial period of 10 years. All high voltage equipment for the two connected systems, such as converter technology, transformers and switchgear, will be manufactured by Siemens Energy in Europe.
“The percentage of renewable energy in the electricity supply of Germany will increase to 80% in 2030. Therefore, it is important to build new wind farms. but the energy, as a last resort, It won't make sense if it doesn't reach consumers. We also need to invest in the grid to reliably supply the country with sustainable energy.”, dice Tim Holt, member of the Siemens Energy Management Board.
