Germany-based Pfisterer to Provide Cable Systems for Siemens Energy’s Offshore Grid Connections
Germany-based electrical connection technology supplier Pfisterer has recently been awarded a contract from Siemens Energy to supply turnkey cable systems for the BorWin4 and DolWin4 offshore grid connections. These platforms will play a crucial role in transmitting offshore wind energy to the German mainland, significantly contributing to the country’s renewable energy supply.
Pfisterer’s scope of work includes the implementation of the entire 66 kV AC cable infrastructure between the gas insulated switchgear (GIS), transformer, and submarine cable connection on the DolWin4 and BorWin4 platforms. This involves planning, comprehensive engineering services, as well as installation and project management.
On these platforms, alternating current generated by offshore wind turbines will be converted into direct current to maximize efficiency and minimize losses during the transportation of electrical energy over long distances to the mainland.
Both BorWin4 and DolWin4 are expected to become operational in 2028, located approximately 125 kilometers northwest of the island of Borkum in the North Sea. With a transmission capacity of 900 MW each, these platforms will be able to transport enough electricity to meet the energy needs of a large city like Hamburg, which has a population of 1.8 million inhabitants.
Stefan Kuhn, Project Manager at Siemens Energy, commended Pfisterer as a reliable partner in the successful implementation of the BorWin4 and DolWin4 projects, citing the company’s technical expertise and proven solutions. Meanwhile, André Roth, Senior Project Manager HV Cable Systems at Pfisterer, emphasized that these projects reinforce their position as an innovative and dependable partner for complex offshore endeavors, supporting the development of future-proof energy infrastructure.
By collaborating on these offshore grid connections, Pfisterer and Siemens Energy are driving the growth of renewable energy sources in Germany and advancing the country’s transition to a more sustainable energy future.
