Located 85km from the island of Borkum, the 980MW project was awarded to Vattenfall by RWE Renewables, a subsidiary of German energy company RWE.
Vattenfall said it had informed the German authority of its decision to exercise its right of entry to the N-7.2 project, which allows it to develop and build the wind farm.
Vattenfall offshore wind head Catrin Jung said: “This is an important milestone for us in Germany as the government aims to increase the generation of electricity from offshore wind to 30GW by 2030.
“Vattenfall strives to contribute to this goal through this and other potential projects.
“Rapid expansion of renewable energy is key to permanently reducing Germany’s dependence on fossil fuels.”
The N-7.2 project could be linked to the German electricity grid in 2027 once Vattenfall has reached a final investment decision.
The wind farm was initially developed by a consortium led by Strabag under the name ‘Global Tech II’, before Vattenfall acquired it in 2016.
It was later re-auctioned under a new offshore wind tendering system, with Vattenfall having the right of entry.
Vattenfall currently has a total of 4.2GW of onshore and offshore wind capacity, generating 11.2TWh of energy a year.
The company operates the DanTysk and Sandbank wind farms in Germany.
In June this year, Vattenfall decided to acquire an 85% stake in two offshore wind farms, Vidar and Poseidon, from wind power company Zephyr.
With a combined capacity of 2.8GW, the offshore projects will be developed between 25km and 27km from the Swedish west coast, north of Gothenburg.
Vattenfall and Zephyr plan to develop the early-stage projects and apply for all necessary permits for establishment together.
