07 Jan 2020: Update 7th January 2020: Approval was granted for lifetime extension. On 11 April 2019, Vattenfall submitted an application to the Scottish Ministers for the variation of the existing consent to extend it from 22 to 25 years (excluding decommissioning), in order to align with the design life of the wind farm assets. Specifically, the MHI Vestas V164-8.0 MW turbines have a structural design life of 25 years, indicating that they do not require additional maintenance in excess of manufacturers’ recommendations over this time period. Final Commissioning took place on the 25th July 2018; therefore according to the original consents the wind farm will be operational until 25th July 2040. The current Marine Licence 04309/18/3 remains in force until 31st December 2041 therefore is valid for approximately 23 years after Final Commissioning. Vattenfall requested a screening opinion from Marine Scotland for a potential extension in September 2018. A screening opinion was given by Marine Scotland in December 2018 confirming that an EIA is not required for the variation.
