Trianel Windpark Borkum (formerly Borkum West II) 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.[2] The project was approved for construction in 2008[3] and will cost over €1 billion to construct once fully operational (€900m for phase I alone). 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 (5 MW turbines) on Tripod foundations.[4] It was connected to the grid in August 2015.[5] In the six months before March 2016 the wind farm produced 452.33 GWh,[6] i.e. a capacity factor of 51.6%.
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 expected in the first half of 2017 after which construction could start in early 2018 for a planned completion in the fall of 2019.[7] Cost is €184/MWh.[8]
