Windfarm number 12 is in the pipeline for the Glenkens.
Fife-based Burcote Wind has revealed it is aiming to build 36 turbines at Longburn between Carsphairn and Moniaive in a £130 million scheme.
If the proposal and the other 11 developments currently being worked on are given the go ahead it would take the number of Glenkens turbines to well over 300.
The plans have come under fire from local pressure group Turbine Watch 312 (TW312).
The organisation’s Keith Mycock said: “It is a matter of great concern that more and more windfarm developments are being announced almost weekly.
“There are more than 1,000 large turbines already proposed for Dumfries and Galloway, which will make it one of the regions with the highest number of turbines in the UK.
“What is even more worrying is the trend for the largest turbines being proposed closer and closer to the most sensitive areas and communities of the Stewartry.
“The nature of these communities will be changed forever even if only the proposals already in the pipeline go ahead.”
The Longburn plan is the second Stewartry scheme Burcote Wind is working on after announcing plans for a £90 million development at Benshinnie near Parton last year.
The company says it will be at least 12 months before a planning application is lodged for Longburn and, when up and running, the farm could have a capacity of 108 megawatts – enough to generate electricity for more than 60,000 homes.
Burcote is also planning to set up a community benefit scheme worth £540,000 annually – which could total £13.5 million over the development’s 25-year lifespan.
Company chairman Graham Brown said: “We think this is a very appropriate site for a windfarm, with the capability to generate sufficient electricity to power many thousands of homes.
“Of course, there is still a lot of detailed work to be done to assess the site and we are a long way from submitting a planning application.
“At the same time, we’re keen to make sure that we listen carefully to any specific issues or concerns the local community may raise so that, wherever possible, these are reflected in the final planning application.
“We’re also committed to working in partnership with local communities to ensure they benefit substantially if this project goes ahead.
“For both of these reasons, we’re announcing our draft proposals now to give the local community ample opportunity to feed into them before we submit a planning application.”
The plans have also come under attack from Galloway Landscape and Renewable Energy (GLARE).
They recently made a submission to the Energy and Climate Change Committee at Westminster expressing their concerns about the merits of community benefit funds.
There are currently two windfarms – Windy Standard and Wether Hill – up and running in the Glenkens.
Others presently in the works include Blackcraig, Margree, Qauntans Hill and Loch Urr, while Windy Standard could be extended.
If all are developed to their full potential there would be 350 turbines in Glenkens windfarms, with more in stand alone developments.
