France, Levallois-Perret: On Thursday 15 May 2014, the ground-breaking ceremony for the onshore converter station took place at the Dörpen West site in Heede, Germany, with representatives of Transmission System Operator TenneT, contractor Alstom and the mayors of the joint municipalities of Dörpen and Heede taking part.

The onshore station is a key part of the 900 MW High Voltage Direct Current (HVDC) transmission grid connection; it will link major wind farms in the south west of the German North Sea to the onshore transmission grid. The connection is scheduled to be completed by 2017.

“DolWin3 is pivotal to offshore wind energy, and will contribute significantly to the future of energy supply.” says TenneT’s Offshore Managing Director, Wilfried Breuer. “We are happy that we can once again use combined European expertise for the implementation of clean energy generation offshore”.

“As general contractor, Alstom will build the complete infrastructure to transport offshore wind power via HVDC technology to the onshore grid, with low electric losses. Alstom has over 50 years of experience in HVDC technology and this project showcases our latest innovation in transmission. At the same time we are proud to contribute to Germany’s energy transition.” said Gerhard Seyrling, Alstom Grid’s Vice President for Central & Eastern Europe and Russia.
The DolWin3 project is the third connection in the offshore DolWin wind farm cluster in the German North Sea. It will use Direct Current (DC) technology with voltage source converters (VSC) to deliver the energy generated at sea through an 83 kilometres (km) sea cable to the mainland. From the coast, the wind power will then be transported another 79 km via an underground cable to the Dörpen West converter station.
