Plans for an £8m wind farm at Barrel Law, north west of Roberton, have been rejected by councillors.
The proposals would have seen seven turbines up to 132m in height erected on land next to the existing Langhope Rig wind farm.
The development site, where a scheme for seven turbines is being proposed, is located approximately 7km south west of Ashkirk, 3.5km north-west of Roberton, 9km west of Hawick and lies 2km south of the operational Langhope Rig Wind Farm.
The company behind the plans, ABO Wind UK, has faced opposition from residents, community councils and Scottish Borders councillors ever since it first announced its intention to develop the site in 2012.
The council’s initial rejection of those plans in 2013 was prompted by concerns voiced by the Ministry of Defence over possible interference with its radar systems at the Spadeadam Royal Air Force base, near Brampton in Cumbria.
The firm’s plans were subsequently revised and reduced from eight turbines to seven, prompting the MoD to withdraw its objections and officers in Scottish Borders Council’s planning department to recommend approval.
The council’s planning and building standards committee took a different view at its meeting today, however.
Speaking in favour of rejecting the plans again, Kelso councillor Simon Mountford said: “I think what it really boils down to is whether the impacts are adverse, significant and unacceptable.
“Scottish Natural Heritage talks about the impacts at the nearby reservoir as being significant and adverse.
