Scottish wind farm impact 'underestimated'
Developers sometimes under-assess the impact of wind farm noise and appearance on residents living nearby, according to new research.
Climate change body ClimateXChange looked at 10 wind farms in Scotland.
It concluded that in some cases what was set out in planning applications did not match the actual impact.
The test sites included wind farms at Dalswinton in Dumfries and Galloway, Achany in the Highlands, Drone Hill in the Borders, Hadyard Hill in South Ayrshire, Little Raith in Fife and West Knock Farm in Aberdeenshire.
It also found that efforts to engage with the public had not always adequately prepared residents for the visual, shadow flicker and noise impacts of a development.
The information was gathered through a combination of residents' surveys and assessments by professional consultants.
Project manager Ragne Low said: "As the study has focused on issues relating to the planning process, we are confident that the findings will feed into improved practice in measuring the predicted impacts of proposed wind farms and in communicating this to decision-makers and those likely to be affected.
"The findings point to several possible improvements in planning guidance and good practice.
"Some have been implemented in the time between the case study wind farms being planned and built, and the present. The study will contribute to building on these improvements."
Linda Holt, spokeswoman for the campaign group Scotland Against Spin, welcomed the findings.
She said: "For too long, people who have complained about wind farms have been dismissed as nimbies and we applaud the energy minister Fergus Ewing for commissioning this work.
"The recommendations show that the planning system is ill-equipped to address potentially adverse impacts on wind farm neighbours and we urge the Scottish government to lose no time in implementing them.
"For too long, decision-makers on wind farms have been asked to determine applications while blind-folded about the true impacts of placing enormous industrial machines near people's homes."
A spokesman for Scottish Renewables said: "This study highlights the high standards of guidance available for those planning an onshore wind farm in Scotland, and we were pleased to see the sector has been putting these into practice.
"The industry has long worked with government and its agencies to put these high standards in place and this report demonstrates how much we have continuously improved, while identifying areas for further improvements for future schemes."
A Scottish government spokeswoman said: "We welcome the publication of the wind farm impacts study report which is the first of its kind in the world and presents the findings of a two-year study involving a wide-range of interest groups.
"The report shows improvements have already been made in our planning system, which is rigorous and ensures appropriate siting of wind farms, and studies like this will make sure this improvement continues, and we look forward to considering the recommendations carefully.
"Our policy on wind farm applications strikes a careful balance between maximising Scotland's huge green energy potential and protecting environmental interests and residential amenity."
