A foundation stone for the land-based converter station, which is part of the BorWin3 grid connection project, was laid yesterday.
At the converter station’s Emden / East site, a time capsule with coins, national newspaper and building plans was taken into the ground and thus marked the groundbreaking ceremony.
With the BorWin3 project a high voltage direct current (HVDC) transmission of 900MW will be realized from offshore wind farms to the high voltage grid in Emden.
This 160km long grid connection will link several wind farms to the mainland. The 155kV alternating current supplied by the wind farms will be transformed into 320kV direct current on the BorWin3 offshore platform.
The BorWin3 link will transport power via cable over 130km at sea and a further 30km on land to the grid feed-in point in Emden. The direct current will then be converted back into alternating current for further transmission and distribution.
