Trianel Windpark Borkum
Trianel Windpark Borkum is an offshore wind farm near Borkum. Its first phase of 40 turbines rated at a total capacity of 200 MW is operational, with a planned, additional 200 MW in a second phase. The project was approved for construction in 2008 and will cost over €1 billion to construct once fully operational. Originally known as Borkum West II the name was changed to Trianel Windpark Borkum in early 2013.
Phase 1 of the installation was completed in the 4th quarter of 2014 and consist of 40 Areva M5000-116 turbines on Tripod foundations. It was connected to the grid in August 2015. In the six months before March 2016 the wind farm produced 452.33 GWh, i.e. a capacity factor of 51.6%.
The power is delivered via the offshore converter station HVDC DolWin1 to the German onshore Dörpen West substation near Heede.
In September 2016 Senvion was awarded a conditional contract for the second phase, for 32 upgraded 6.2M152 turbines rated at a total capacity of 203 MW. A final investment decision was made in the first half of 2017 after which construction started in early 2018 for a planned completion in the fall of 2019. The wind farm was fully commissioned in 2020 after delays caused by the bankruptcy of Senvion, at a cost of €184/MWh.
