State Grid to Contribute to Germany's Offshore Flexible DC Wind Power Project

A consortium of two subsidiaries of State Grid Corporation of China (State Grid) and US-based McDermott on March 10 signed an agreement with the European power transmission operator TenneT on the convertor station element of Germany's BorWin6 offshore flexible direct current (DC) wind power transmission project.

Located in German North Sea waters, the BorWin6 offshore flexible DC wind farm has the largest installed capacity of its kind in the region. With a rated voltage of ±320 kV and a rated capacity of 980,000 kilowatts, the wind farm is scheduled to be put into operation by the end of 2027.

State Grid's subsidiaries, Global Energy Interconnection Research Institute Co. Ltd., and C-EPRI Electric Power Engineering Co., Ltd will be responsible for the project's electrical design and analysis, electrical equipment supply and on-site DC system adjustment. McDermott will shoulder design and construction of the offshore platform and land convertor station.

State Grid's participation in the project is of great significance in promoting high-quality and co-construction of the Belt and Road and deepening China-Europe green energy cooperation.

The flexible DC power transmission technology is currently the most flexible and adaptable new generation of power transmission technology in the world, and is a key technical method to support energy transmission and new-type power system construction.

Since 2013, State Grid has been devoted to development and research of offshore wind power flexible DC technology and has accumulated profound technological experience in system access, customized DC equipment development and engineering design. The company launched cooperation with European power enterprises since 2017, and has been responsible for technical demonstration and preliminary design of several flexible DC projects in the region.
