BorWin2

With a capacity of 800 megawatts (MW), BorWin2, together with HelWin1 (576 MW), is the first large-scale offshore connection that TenneT has realised, enabling more than one offshore wind farm to be connected to the power grid for the first time.

About the project

200 kilometres long and 800 megawatts strong direct current connection

BorWin2

Since January 2015, the wind turbines of the offshore wind farms have been feeding large amounts of clean wind energy into the German electricity grid via BorWin2.

The electricity is transported from the North Sea to the mainland via a 125-kilometre-long submarine cable. The 75-kilometre long land route runs from the Hilgenriedersiel landing point to the Diele grid connection point. The onshore route for BorWin2 was constructed parallel to the route for the BorWin1 project. This bundling has limited the impact on nature and the environment.

Connecting concept:

The electricity generated at sea is collected in the wind farm's own transformer station. From there the energy is transported to TenneT’s offshore converter platform via a 155 kilovolts three-phase alternating current (AC) cables. The conversion of AC to direct current (DC) takes place in the offshore converter station. The electricity is then transported by submarine and underground cable to the corresponding land station. Here, the electricity is converted back into AC and fed into the TenneT extra-high voltage grid.
