Arkona , officially Arkona Basin Southeast , is the name of an offshore wind farm in the German exclusive economic zone in the Baltic Sea . The area is 35 kilometers northeast of the island of Rügen and directly southeast of the Wikinger offshore wind farm located there .

60 wind turbines on an area of ​​37 km² have an installed capacity of 385 MW. This means that the wind farm can theoretically supply 400,000 households with electricity.

history

At the request of AWE Arkona-Windpark-Entwicklungs-GmbH on May 12, 2000, the responsible Federal Maritime and Hydrographic Agency (BSH) in Hamburg ordered the construction and operation of 80 wind turbines, including the ancillary systems such as internal cabling and the transformer platform, on March 15 Approved in 2006. On April 5, 2017, the BSH amended ancillary provision no.23 so that the permit would have expired if the construction work to install the systems had not started by July 31, 2017.

At the end of April 2016, E.ON made the investment decision to build the wind farm by 2019. According to its own information, the group held half of the shares; the other project partner is Equinor (formerly: Statoil). E.ON acted as client and operator. The investment volume was given as more than 1.2 billion euros.

The opening ceremony took place on April 16, 2019 by Chancellor Angela Merkel .

As part of the swap between RWE and E.ON, all of the two companies' generating facilities were transferred to RWE. RWE is now the owner of the 50 percent stake in the Arkona wind farm and also acts as the operator.

In October 2019 it was announced that Equinor is selling 25% of its stake to a fund advised by Credit Suisse Energy Infrastructure Partners AG .

construction

A symbolic laying of the foundation stone for the entire project took place in mid-August 2016 on the construction site of the company building in Sassnitz-Mukran on the island of Rügen .

On July 14, 2017, a 500-meter safety zone was set up around the planned locations of the external wind turbines of the wind farm so that construction work on the construction site can begin. This safety zone, the entry of which is prohibited for unauthorized vehicles, was connected to the safety zone of the neighboring wind farm Wikinger. In August 2017, the offshore construction work began with the setting of the monopiles . By November 2017, the installation of the monopile foundations was carried out with the installation vessel Sea Challenger of the A2SEA and the special vessel Svanen of the company Van Oord .

In April 2018, the 4,000-tonne transformer station was lifted onto the foundation of the transformer platform with the help of the heavy-duty crane ship Oleg Strashnov .

The installation of the turbines was carried out from June to October 2018 with the installation vessel Sea Challenger from A2SEA. The first turbine fed electricity into the grid at the end of September 2018.

technology

The 60 enhanced wind turbines of the Siemens Gamesa SWT-6.0-154 type have an installed capacity of 6.4 MW each and a rotor diameter of 154 meters. They are anchored with monopiles in the seabed, which is between 23 and 37 meters below the sea surface. The monopiles are up to 81 meters long and have a diameter of up to 7.75 meters. They were produced by the EEW Group in Rostock. A thermally sprayed aluminum coating was used instead of conventional aluminum anodes to protect against corrosion . For this, E.ON Climate & Renewables received the German Renewables Award 2017 in the category “Product Innovation of the Year”.

Mains connection

The wind turbines are connected by medium voltage cables to the “Arkona” transformer platform in the wind farm, which transforms the electricity to a maximum voltage of 220  kV . From there, the electricity is transferred to the substation in Lubmin on the mainland via submarine cables on the "Ostwind 1" route . Ostwind 1 consists of a three-phase line system with three cables, each of which is 90 kilometers long at sea and three kilometers on land. There is also an electrical connection to the “Andalucía” transformer platform in the neighboring Wikinger offshore wind farm . The 50Hertz Offshore company is responsible for the grid connection .

Service port

The Mukran Port in Sassnitz serves as the basis for the service operations.
