Grid connection of Horns Rev 2 200 kV offshore wind farm

Connecting the 91 wind turbines of Horns Rev 2 offshore wind farm off the west coast of Jutland required the following installations:

• A transformer platform, which collects the power from the wind turbines and increases the voltage level from 33 kV to 150 kV. The platform is 37 m from the seabed to the helipad.
• A 42 km 150 kV submarine cable from the platform to the shore where it is connected to a cable substation.
• A 150 kV land cable to Endrup substation where the voltage level is increased to 400 kV.

The grid connection, which was budgeted at EUR 110 million, was completed in May 2009.
