BARD Offshore 1 is a 400 megawatt (MW) North Sea offshore wind farm with 80 BARD 5.0 turbines. Construction was finished in July 2013 and the wind farm was officially inaugurated in August 2013. The wind farm is located 100 kilometres (62 mi) northwest of the isle Borkum in 40 metres (130 ft) deep water.
Laying of cables to connect the wind farm started on 23 July 2009. The 200 km connection is the longest of its kind in the world. It is also the first connection of an offshore wind park realized as HVDC-transmission. Construction of the wind turbines began in March 2010. The first turbine became operational at the beginning of December 2010. Construction was assisted by the purpose-built Wind Lift 1 barge / platform, which placed the 470 ton, 21 meter foundations on the sea bed.
The project has run into serious and unclear problems, including being three years behind schedule and, at a cost of €3 billion, run significantly over budget. A diver and a worker died during construction. The farm was supposed to go online in August 2013, but a series of setbacks, including a fire at a transmission station in March 2014, have delayed its activation. BARD went bankrupt in November 2013. Problems include overvoltage and harmonics between BARD and the BorWin 1 grid link and BorWin Alpha HVDC converter platform.
BARD's original owner had decided to make all components within the company, and troubles from the custom transformer are unrelated to standard equipment used elsewhere.
As of January 2015, most of the turbines are not supplying power to shore, costing ratepayers €2million per day.
In September 2015, StatKraft and Ocean Breeze extended their contract for two years.
By May 2016, the company website stated that the wind farm had produced 3 TWh, and was running stable at full capacity.
