The proposed Aikengall-2a wind farm – about eight miles south of Dunbar – would have 19 turbines after the developer agreed to cut its original proposals by 30%.
But this second plan has been rejected by a vote of 5-2 on the Borders planning committee on landscaping and amenity impact grounds.
Community Windpower said the development would generation more than 200,000 MW of electricity, equivalent to the needs of 55,000 homes.
The Cheshire-based company – which already operates the nearby 16-turbine Aikengall wind farm – also has wind farms in South Lanarkshire and Ayrshire and an operating base at the ‘Three Heids’ business park, near Bellshill on the M8.
It has agreed a deal with Campbeltown-based Wind Towers to buy 50 turbine towers for future developments as part of a £1 billion investment in renewable energy in Scotland.
The company did not reply to inquiries from Scottish Energy News as to whether it planned to appeal the Borders council refusal.
