Clash Gour Airspace Change Proposal

Force 9 Energy and EDF Renewables, through its subsidiary Clash Gour Holdings Ltd has today launched a consultation relating to changes to the airspace around the consented Clash Gour Wind Farm. The consultation will close on Wednesday 31st May 2023.


Clash Gour Wind Farm was consented by Scottish Ministers in October 2022.  The consent includes a set of conditions which control how the project should be developed and built. 


The conditions require that agreement should be reached with both Inverness Airport and Royal Air Force Lossiemouth on a solution to ensure that Air Traffic Control services are not adversely affected by the wind farm (a radar mitigation solution).


We are exploring several ideas for a radar mitigation solution, including an ‘Airspace Change Proposal’ (ACP), which is the subject of this consultation.


The proposed ACP is seeking to introduce a ‘Transponder Mandatory Zone’ (TMZ) in the airspace above and around Clash Gour. It means that to fly above the wind farm, an aircraft will need to carry a ‘transponder’, a piece of equipment typically carried by most aircraft, which provides air traffic control with an accurate location and height of the aircraft. This will not result in any changes to the regular flight patterns of the majority of aircraft in the area.


All ACPs must be managed by the Civil Aviation Authority (CAA) and follow CAA procedures. Guidance on the regulatory process for changing the notified airspace design is available in the CAA Civil Aviation Publication (CAP) 1616. Full details of what ‘Airspace Change’ means can be seen on the CAAs website:


Agreement on the proposed TMZ is one of the mechanisms which will therefore allow Clash Gour wind farm to be built and the expected benefits of the project to be fulfilled.
