New radar system at Glasgow Airport mitigates effects of local wind farm
Due to their height and movement patterns, wind turbines can have a range of impacts on navigational systems, mimicking the appearance of real aircraft.
Plans for one of the largest wind farm developments in Scotland have been given the green light following the installation of a state-of-the-art radar system at Glasgow Airport.
Together with air traffic services company, NATS, and Banks Renewables, Glasgow Airport has introduced a new radar that can mitigate the impact of the Kype Muir Wind Farm near Strathaven, South Lanarkshire. The development will generate 88.4MW of renewable energy from its 26 turbines.
NATS will manage the dual Terma SCANTER 4002 radar system which is capable of supporting air traffic control requirements and mitigating the impact of the turbines. The system is now operational and NATS has secured the contract to operate and maintain the service for the 25-year life of the wind farm.
Due to their height and movement patterns, wind turbines can have a range of impacts on navigational systems, including being detected by Primary Surveillance Radar (PSR) and appearing on air traffic control screens. This can have a number of impacts including distracting controllers, masking ‘real’ aircraft and mimicking the appearance of actual aircraft to the extent that they must be avoided by other aircraft. Such impacts can have a detrimental impact on the safety, efficiency and capacity of airspace surrounding the airport.
As a statutory consultee, Glasgow Airport must assess wind farm development proposals up to 50 kilometres away. Importantly, it must ensure any proposed development will not pose a risk to the safety of the 30 airlines who fly over nine million passengers to and from the airport every year.
Glasgow Airport Managing Director, Mark Johnston, said: “We are very pleased to announce that the system is now fully operational. For the last three years, the Airport’s planning team has been working extremely hard with our partners from NATS and Banks Renewables to develop this wind turbine mitigation solution in what is a very complex and safety critical environment. As well as resolving the issue with Kype Muir, the mitigation may also have the potential to resolve issues with other future wind farm proposals, which can only be of benefit to Scotland’s renewable energy sector.”
Cabinet Secretary for Transport, Infrastructure and Connectivity, Michael Matheson, said: “It’s great to see Glasgow Airport hosting the launch of this new radar system, which is a significant development for aviation safety. The new radar is able to distinguish between aircraft and wind turbines situated at Kype Muir Wind Farm, and this technology will be invaluable with the ever-growing sustainable energy sector.”
Andrew Liddell, Technical Director with Banks Renewables, said: “We’re especially thankful to Glasgow Airport for engaging with us to deliver the new radar. This means that not only will our new wind farm stay clear of any radar detection – but other new wind farms may also benefit from this regional solution. We also acknowledge how proactive and instrumental the Scottish Government has been in helping deliver such a positive outcome.”
Paul Beat, NATS General Manager at Glasgow Airport, said: “We’re delighted to have worked with Glasgow Airport, Banks Renewables and TERMA to deliver a mitigation solution that both supports safe and efficient air traffic services, while also allowing this important wind farm development to be built and make a major contribution to the Scottish Government’s renewables strategy.”
Glasgow was one of the first airports in the world to deploy large-scale wind turbine mitigation in the form of infill radar and has continued to innovate by deploying single turbine blanking in response to the increasing number of developments.
As a result, it has approved 90 per cent of the 495 wind turbine applications it received between October 2012 and August 2016. These projects have the potential to generate more than 700MW of energy.
