Shadow flicker is a well documented feature of windfarms that is caused by the sun setting or rising behind the spinning blades of a turbine. The phenomenon creates a pulsating light effect in rooms that would ordinarily be basked in sunshine and that can last for 15 minutes of more as the sun moves across the sky.
The affect of shadow flicker is easy to predict at the design time of a windfarm (the ancient Britons managed quite well with their stone circles - even without the aid of computers) and so you would think that a well designed windfarm would not cause the problem at all.
Unfortunately for us many properties are affected by shadow flicker from the PowerGen Renewables windfarm here in Cumbria, some at sunrise and some at sunset; some by just one turbine and some by as much as four turbines. The effect lasts for different lengths of time but is typically, for about 15 to 30 minutes per turbine. As the sun rises and sets in a different place according to the time of year, the timing of the nuisance also varies.
It really is uncomfortable sitting in an affected room and makes watching the TV difficult if not impossible, the pulsating effect is disturbing to say the least and we believe that it may be dangerous to epilepsy suffers.
Unfortunately when local residents complained about the nuisance (and despite the assurances given at the planning stage) PowerGen Renewables' Matt Britton has publicly declared that his company is not prepared to take any action to alleviate the problem.
