Iberdrola has officially cut the ribbon for the Wikinger offshore wind farm having invested over €1.4 billion in its realisation. Over 2,000 employees from 20 different countries participated in this milestone project in the Baltic Sea.

Wikinger is fully operational with a capacity of 350-MW and connected to the German grid, supplying renewable energy for up to 350,000 homes. Iberdrolas stated that the array displaces the emission of nearly 600,000 tons of CO2 per year.

The Chairman of Iberdrola, Ignacio Galán, commented: “Wikinger represents a new step in our commitment to supplying clean, efficient and reliable electricity. We will continue to champion offshore wind technology since it enables us to drive the energy transition to a sustainable, low carbon economy.”

Galán added: “this wind farm is a clear example of cutting-edge technology and it showcases the enormous potential of Europe's energy industry to lead the Continent's reindustrialization through innovation.”

To build the project, 280 piles were installed. Measuring 40m in length by 2.5m in diameter, and a unit weight of 150 tonnes, they were all built by Spanish company Windar. A total of 70 foundations were laid on them, each weighing 620 tonnes, manufactured by Bladt Industries in Lindo (Denmark) and Navantia, at its shipyard in Fene (Spain).

A total of 70 Siemens Gamesa (Adwen) AD 5-135 turbines were installed at the site after being manufactured at the company's plants in Bremerhaven and Stade (Germany). With a total height of 165m, they consist of a 75m high tower, a 222-tonne nacelle and a 135m diameter rotor, with each blade measuring 67m long. Each unit has a 5MW capacity.

Finally, one of Wikinger's key pieces of infrastructure is the Andalucía offshore substation, which will be used jointly by Iberdrola and 50Hertz, an electricity system operator in Germany. Weighing around 8,500 tonnes, the energy heart of the wind farm was also built by Navantia in Puerto Real in southern Spain.

Iberdrola recently confirmed that it has a goal to operate a total of 3GW of offshore wind capacity both in Europe and in the U.S. by 2023. The company stated that the necessary investment to achieve this goal is close to €9bn.

Located off the north-east coast of the German island of Rügen, the Wikinger project marks Iberdrola's entry into the German electricity market, where it has just been awarded the construction of two other offshore wind farms: Baltic Eagle (476 MW) and Wikinger Süd (10 MW). Together with Wikinger, these three wind farms, located off the island of Rügen, will have a total installed capacity of 836MW and represent a combined investment of €2.5 billion.
