Renewable energy firm RWE Innogy has received the necessary permit from the Federal Maritime and Hydrographic Agency to begin the construction of the €3bn Innogy Nordsee 1 offshore wind farm off the coast of Germany.
The wind farm site is located about 40km north of the island of Juist and covers around 34km².
RWE Innogy chief executive officer Professor Fritz Vahrenholt said, "The first permit for our Innogy Nordsee 1 offshore wind farm is an important milestone for us which we have been pursuing for about three years."
Nordsee 1 will see the installation of 54 wind turbines and, together with Nordsee 2 and Innogy Nordsee 3 wind farms, some 160 wind turbines with a capacity of about 1,000MW capacity are to be installed on a 100km² area in the next few years.
RWE Innogy said the permits for Nordsee 2 and 3 are expected shortly.
The company acquired the rights for the Nordsee 1 project from developer ENOVA at the end of 2008.
The tendering process for the key components of the first development stage such as turbines, foundations, cables and substation began in 2011 and is still ongoing.
