We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).
Clean wind energy from the eastern North Sea
About the project
HelWin2 is a high-voltage direct current (HVDC) transmission system with a capacity of 690 MW. This project is the third connection of TenneT in the eastern North Sea. The line runs from the HelWin beta converter station 85 kilometres as submarine cable to the landing point in Büsum and from there 45 kilometres as underground cable to the converter station in Büttel in Schleswig-Holstein.
The offshore converter platform HelWin beta is a subsidiary platform of HelWin alpha, the heart of the grid Connection HelWin1.
There are only about 20 metres between the two platforms. Both platforms are directly connected by a bridge. This means that the helicopter deck and the crew accommodation can be shared for the employees at sea. This is an innovative and cost-saving concept because it makes use of technical and logistical synergies.
