BorWin3

160 kilometers long and 900 megawatt DC connection

Facts

Connection

  • 160 km long and 900 MW capacity
  • 30 km onshore cable
  • 130 km offshore cable

Grid connection point

  • converter station Emden/Ost

Status of project

  • initial operation planned for 2019

About the project

BorWin3 is the third project to be realized by TenneT in DC technology off the coast of Borkum, alongside the BorWin1 and BorWin2 grid connection projects. At its Emden/East site, TenneT is building a converter station with a substation to convert the energy generated at sea from direct current into three-phase current and feed it into the power grid from there. In total, a distance of 160 kilometres must be bridged, whereby the wind power is first transported over a 130 kilometre long submarine cable to the west of Borkum to Hamswehrum and from there over a 30 kilometre long underground cable to Emden/East.

The foundation stone for the onshore converter station was laid in May 2016 and work has been underway ever since. At the same time, the BorWin gamma offshore platform is currently being built and equipped in Dubai before making its way to the North Sea. According to current planning, the 900 megawatt (MW) direct current connection is scheduled to go into operation in 2019.
