Windfarm bosses objected to a rival operation being built – because they were afraid their wind would be “stolen”.
Plans for two windfarms in rural Denbighshire were surprisingly snubbed by the county on Wednesday.
And last night, it emerged one rival windfarm had expressed fears its wind may be “stolen” if new turbines were built nearby.
Council officials who assessed whether one windfarm could take another’s wind admitted it was “inevitable”.
Denbighshire councillors were advised by their own planners to give the green light to two windfarms totalling 29 turbines, up to 125m tall, near Nantglyn.
But the county snubbed both plans – and went against their officers’ advice.
A plan by Brenig Wind Limited, would have seen 16 turbines up to 100m tall being built on land east of Llyn Brenig.
And it has now emerged one of the more bizarre objections to the proposal came from the managers of the 25-turbine windfarm Tir Mostyn, immediately to the north and east of the proposal.
A Denbighshire planning document shows Tir Mostyn bosses feared “Tir Mostyn and Brenig windfarms will interfere with one another’s generation potential.”
It goes on to say: “A specific objection is lodged over potential problems which could arise from the physical location of turbines on the Brenig site, in terms of disturbance to windflow to other turbines reducing the efficiency and potential generation of electricity.
“The issue is the occurrence of ‘windflow wake’, which could affect turbines at Tir Mostyn or Brenig, dependent on wind direction and speed.
“The view is taken here there would inevitably be an impact on wind resource between a turbine development at Brenig and Tir Mostyn, each affecting the other’s dependence on wind direction, but the significance should be of limited bearing to the determination of the application.”
Studies by Brenig Wind Ltd on the layout of Tir Mostyn showed removing trees and installing Brenig turbines further away “will have a net benefit to Tir Mostyn” and not lead to concern about ‘stolen wind’.
No-one from Hg Capitals, who run Tir Mostyn windfarm, was available to comment. The 21.25mw windfarm is capable of annually lighting up 15,500 homes.
Tir Mostyn, which has turbines up to 75m tall, opened in Autumn 2005, despite £100,000 of damage being caused in an arson attack earlier that year.
