Planning councillors have voted to oppose proposals for a 23-turbine wind farm near New Galloway.
The council has decided to object to the Blackcraig scheme
Officers had recommended backing the Blackcraig plans put forward by Scottish and Southern Energy.
However, the planning committee voted to oppose the proposals and seek national guidance on the development of wind farms in the region.
A final decision will now be made by the Scottish Executive taking into account the council's objections.
Planning committee councillors voted 12 to five in favour of making an objection to the plans.
That backed a similar vote by the Stewartry area committee last month.
They argued that the scheme would have an adverse impact on the "landscape, character and amenity" of the area.
Members of the planning and environment committee endorsed that view.
The scheme has prompted significant levels of objection and support.
More than 500 letters protesting against the plans have been lodged as well as a 500-signature petition backing the scheme.
