Our role relating to solar and wind energy
Renewable energy projects are being constructed throughout the UK, ranging from single structures to developments encompassing over one hundred wind turbines. The physical characteristics of such projects coupled with the size and siting of the developments can result in effects which impact on aviation. This can be because the physical structure is close to an air route or aerodrome, or can create interference on air traffic control radar caused by turbines.
Our policy on wind turbine development and related guidance to the UK civil aviation community is set out in CAP 764.
Guidelines to assist those involved in the development of wind farms in ensuring they present no danger to civil and military aviation have been published jointly by the Department of Trade and Industry (DTI), the Civil Aviation Authority (CAA), the Ministry of Defence (MOD) and the British Wind Energy Association (BWEA). Because of their physical size, in particular their height, wind farms can be a hazard to aviation.
Large rotating wind turbine blades may also have an impact on the operation of radar. Many windfarms are already in operation and the number can be expected to increase sharply over the next few years. The Wind Energy and Aviation Interests Interim Guidelines are aimed primarily at all those involved in the consultation process for wind farms, including wind farm developers and local authorities. In particular, it gives guidance to developers on the issues to be taken into account in decisions on the location of wind farms.
