Butendiek ( Low German : "außendeichs", on the sea side of the dike) is an offshore wind farm in the German exclusive economic zone of the North Sea , about 35 km off the west coast of northern Schleswig-Holstein . Construction of the wind park with 80  Siemens SWT-3.6-120 wind turbines, each with a nominal output of 3.6  MW, began in spring 2014 west of the island of Sylt . The 80th wind turbine was built on June 11, 2015. At this point in time, more than half of all systems had already been commissioned. The full commissioning took place in August 2015.

history

Location Butendieks with the other wind farms in the German Bight and their power connection

On September 26, 2000, OSB Offshore-Bürger-Windpark Butendiek GmbH & Co. KG , based in Husum, applied for the construction and operation of 80  wind turbines (WEA). With a decision of December 18, 2002, the construction and operation of the wind farm was approved by the Federal Maritime and Hydrographic Agency (BSH) on the basis of the Maritime Facilities Ordinance . Butendiek is the second German offshore wind farm, after Alpha Ventus the year before, which was approved by the BSH.

In 2007, the project company OSB Offshore-Bürger-Windpark Butendiek GmbH & Co. KG entered into what it called a "strategic partnership" with the Irish company Airtricity . In 2008, Scottish and Southern Energy (SSE) took over Airtricity. In April 2009 the British government increased the remuneration for offshore electricity by issuing two instead of one certificate per megawatt hour generated. A certificate is equivalent to around 3 cents per kWh. As this offered a more interesting alternative for the operator SSE for wind farms in Great Britain, SSE withdrew from the project.

As a result of this, the start of construction was delayed considerably. The aim of the project company was originally to complete the offshore community wind farm by 2012.

Due to financing problems which OSB Offshore Citizen Butendiek GmbH & Co. KG decided on the project, which specializes in wind energy project development company WPD from Bremen to sell. WPD planned to start construction on the wind farm in 2013. The total investment was 1.3 billion euros.

In February 2013, the entire financing was completed and shares in the wind farm were sold to new shareholders:

The opening ceremony took place on September 8, 2015 in the presence of Robert Habeck , Martin Günthner , Jürgen Trittin and others in Husum .

Construction progress

Production of the components should start in 2013. Siemens Windenergie was awarded the contract for the delivery of 80 wind turbines of the type SWT-3.6-120 (nominal output 3.6 MW) with remote monitoring. The foundations were supplied by the Dutch company Ballast Nedam .

So that construction could begin on the planned construction site, a safety zone was set up on March 1, 2014 at a distance of 500 m around the planned locations of the external wind turbines. The monopile foundations were installed by late summer 2014. 40 of the intermediate pieces between the foundation and the wind turbine (transition pieces) were assembled in Lubmin (Mecklenburg-Western Pomerania) and, from June 2014, towed from there by water through the Kiel Canal to Esbjerg in Denmark , which serves as an assembly and equipment port. As early as autumn 2014, the wind turbines that had been built up by then were gradually put into operation, and the wind farm was completed in summer 2015.

The transformer platform built in Antwerp was placed on the previously erected jacket foundation by the Rambiz floating crane in summer 2014 . The high-voltage submarine cable manufactured by Prysmian in Italy , which was supposed to connect the transformer platform with the SylWin alpha converter platform , sank in July 2014 when a barge capsized on its way from Naples to the North Sea in the Mediterranean.

At the beginning of February 2015, 24 of the 80 wind turbines were in operation. The 80th wind turbine was installed on June 11, 2015.

Network connection

The 80 wind turbines are connected at 33 kV medium voltage level to the transformer platform in the wind farm, which transforms the electricity to high voltage of 155 kV. From there, the electricity is bundled and transmitted via a three-phase AC submarine cable to the SylWin alpha converter platform . The grid connection to the country is carried out by the transmission system operator Tennet TSO via high-voltage direct current transmission (HVDC). The converter platform is connected by submarine and underground cables (160 and 45 km) to the shore-side converter station Büttel , which again generates three-phase current. The HVDC system called SylWin1 is designed for 864 MW and went into operation in 2015. The DanTysk and Sandbank offshore wind farms are also connected there .

business

Deutsche Windtechnik , a company of the WPD Group, was entrusted with the technical management .

criticism

The wind turbines are located in the bird sanctuary of the Eastern German Bight , in the FFH area Sylt Outer Reef and in the nature reserve Sylt Outer Reef - Eastern German Bight . At the time of approval, an area designation by the Federal Agency for Nature Conservation was proposed but not yet carried out.

The Naturschutzbund Deutschland (NABU) fears negative effects on the marine environment, bird species (especially loons ) and the harbor porpoises , seals and gray seals that live there . NABU filed a lawsuit against the approval of the wind farm. The action was dismissed as inadmissible due to a lack of legal standing . This judgment became final .

The action brought by the municipality of Sylt , which fears negative effects on tourism and pollution, was unsuccessful until the Federal Constitutional Court . The lawsuit brought by deep-sea fisheries who feared negative effects on shipping traffic was also unsuccessful.

In another procedure, the NABU is requesting the BSH to order measures to prevent danger on the basis of the Environmental Damage Act . This lawsuit was also unsuccessful. The appeal against the judgment was dismissed.

In addition, the NABU asks the Federal Agency for Nature Conservation to order remedial measures in accordance with the Environmental Damage Act on the grounds that the wind turbines threaten an irreversible and relevant loss of habitat for the red- throated and black-throated divers . The lawsuit was dismissed as unfounded.

After the national legal remedies have been exhausted as far as possible, NABU will lodge a written complaint with the European Commission in March 2019 .
