Offshore Projects in the German Baltic Sea

EnBW Baltic 1 - the first German commercial offshore wind farm in the Baltic Sea

EnBW Baltic IApproximately 16 km north of the Darss/Zingst peninsular on a site of around 7 km² a total of 21 wind energy plants and a substation will be built in 2010. The wind energy plant (hub height 67 metres, rotor blade diameter 93 metres) will be anchored with monopiles in sea depths of 16-19 metres. These 35 metre long and 500 ton heavy steel pipes are sunk 25 m deep into the seabed and connected by a 28 m transition piece to the steel tower of the wind energy converter. Scour protection additionally secures the turbine against currents and tides. All wind energy converters are connected together annularly through the farm’s internal network so that whole farm segments do not malfunction during possible disruption. The electricity generated is stepped up in the substation from 33 kV to the transmission voltage of 150 kV and is linked up to the overland network by 50Hertz Offshore GmbH.

After the installation of the foundations in early 2010, the complete wind farm will be built and connected to the network. With a total output of 48.3 MW, around 176 GWh of energy can be generated annually - and over a period of at least 20 years. This can supply around 50,000 households per year.

Wikinger Offshore

In spring 2016 Iberdrola startet to build their offshore windfarm Wikinger.
This is the 3rd offshore windfarm in the German Baltic Sea. It ist located in
the German Exclusive Economic Zone (EEZ), 75 kilometres off the
German Baltic Sea coast and near Rugen Island. On an area covering
around 34 square kilometres exist 70 wind turbines (each 5 MW, Producer: Adwen)
and a substation.

  • Location: Ostsee, 75 km off the mainland, near Rugen Island
  • Size: approx. 34 km²
  • Wind turbines: 70 Adwen AD5 – 135
  • Foundation: 70 Jackets
  • Water depth: 37 – 43 m
  • Total output: 350 MW
  • Completion: November 2017
