In 2016, the Scottish Government granted consent for an eight-turbine wind farm at Mochrum Fell, having found ‘no material considerations’ for refusal.
After further assessments and extensive pre- application consultation with the local community and stakeholders, Falck Renewables submitted a new application in October last year.
This aimed to remove the most prominent turbine in the previously approved scheme and "modestly” increase the heights of the remaining seven turbines.
Dumfries and Galloway Council has been unable to reach a decision on the application, and the company believes there is not sufficient clarity on when a decision will be reached.
Falck Renewables has therefore lodged the appeal in order to secure greater certainty on the timetable for a decision.
The application will now be determined by the Scottish Government’s Directorate for Planning and Environmental Appeals (DPEA).
A spokesperson for Falck Renewables said: “The modest amendments to the already-consented Mochrum Fell Wind Farm would not have a significant effect on the visual impact of the consented scheme.
"The development would create local jobs during the construction and operation phases and would contribute approximately £4.4m to the local economy over the 30-year operating life of the project, if approved.”
