The BARD Offshore 1 wind farm is a real pioneer. It has continually increased its output, and in 2017 it produced the most energy of all German offshore wind farms – 1.5 TWh – thanks in no small part to two Bremen-based companies.
90 kilometres off the coast of Borkum, an island on Germany’s North Sea coast, 80 wind turbines rise from the rough seas on yellow tri-piles. Covering an area of almost 60 square kilometres, the BARD Offshore 1 (BO1) wind farm is one of Germany’s largest. It generates 400 megawatts, providing electricity for 400,000 households. It was also the first commercial offshore wind farm in Germany when it went online in 2010. The wind turbines were manufactured by BARD, a wind power plant manufacturer founded in Emden, East Frisia, in 2003. The company went bankrupt in 2013.
Although plant production was halted, the wind turbines were still producing electricity and needed to be serviced and maintained. To manage this, a new service company called OWS Off-Shore Wind Solutions GmbH (OWS) was founded in 2013. Located on the former premises of BARD, OWS made use of the remaining capacity and machinery.
“In addition to establishing OWS, it was necessary to develop an innovative and sustainable concept for operating the wind farm. We put together an experienced engineering team and started looking for strong and experienced industry partners for OWS,” says Jean Huby, managing director of Ocean Breeze Energy GmbH & Co. KG (OBE), the Bremen-based operator that took over the running of the BARD Offshore 1 wind farm in 2013 following BARD’s bankruptcy.
They found the industry partner they needed in REETEC, a provider of services to the sector. In addition to having decades of experience, REETEC was also familiar with the technology – the company had erected the first BARD prototype.
“The farm was and still is an exciting project for us. Normally, there are a whole host of companies working on a wind farm, such as turbine manufacturers, blade manufacturers and electronics specialists. With BO1, we were able to handle the operation and maintenance ourselves,” says Detlef Lindenau, managing director of REETEC. This presented plenty of opportunities to demonstrate the level of expertise on offer at REETEC, which is based in Bremen’s Überseestadt (New Harbour District).
OWS, working with OBE’s engineering team, and REETEC, working with its partner Wind Multiplikator GmbH, were able to increase the reliability and the efficiency of the farm. “The engineering team at OBE took on a lead role, and our areas of expertise complimented each other perfectly,” says Lindenau. As the engineers could no longer call on the support of BARD, they had to find new solutions.
OBE, OWS and REETEC have been working together on the wind farm since 2015. The partnership has been a success, as the figures show. In 2017, BO1 generated more electricity than any other German wind farm on the North Sea and Baltic coasts. “We’re very proud of that,” Huby says. OBE signed a 10-year service and maintenance agreement with REETEC/OWS in 2017 to ensure that BO1 continues to operate with maximum efficiency and performance.
The work also led to further strategic expansion at REETEC, which took over OWS and its 180 employees in Bremen in 2017. Doubling its workforce in one go was a challenge for REETEC.
The Bremen-based SME was able to take this step thanks to the support of its parent company, EDF Energies Nouvelles (EDF EN). REETEC has been part of the EDF EN Group since 2007. In May 2018, the company rebranded to become REETEC EDF Renewables, a subsidiary of the French conglomerate. Lindenau, REETEC’s managing director, has ambitious plans to make good use of the increased capacity following the acquisition of OWS and the BARD premises in Emden: “We want to establish the first independent offshore service centre on the North Sea coast.”

Will we all be driving hydrogen-powered cars in the future? The course for the future of this resource is currently being set in Bremerhaven.
The whispering of strong winds: The Bremerhaven-based company Deutsche WindGuard GmbH is using a large wind tunnel to research the optimal shape and surface of wind turbine blades. It works for all well-known manufacturers in the industry.
Bremen-based researchers are developing a drone that can autonomously inspect wind turbines. Its USP is its ability to get ‘hands on’.
The state of Bremen covers 420 square kilometres and is home to around 670,000 people. Almost 22,000 companies provide more than 325,000 jobs. Below, we introduce some of the strong sectors that that make Bremen such an excellent business location.
A Bremen-based company has launched the first independent service centre for offshore wind farms. It aims to facilitate servicing procedures for manufacturers and reduce maintenance costs for operators. Workers travel out into the North Sea from the home port in Emden, East Frisia.
Bremen is a key hub for onshore and offshore wind energy. Here we highlight what the region has to offer – from skilled workers and facilities to sites and infrastructure.
Rotor blades withstand both wind and weather for decades. But it does create a problem when it comes to their disposal, as they don't decay and are nearly impossible to incinerate. Bremen's neocomp GmbH has developed a process – unique in Germany – which allows plastics that are reinforced with glass fibres to be recycled in an environmentally friendly way.
Irina Lucke has been at the helm of WAB since December 2016. We talked about her role in the german-wide trade association and the challenges that an ever-changing business and regulatory environment poses for the international wind energy industry.
GeoSea, a subsidiary of the Belgian DEME group, is helping to construct of some of the largest offshore wind farms in the German North Sea – and in Bremen, the company has found the ideal location to carry out its work.
