Energy firm Vattenfall is already developing the South Kyle Windfarm near Dalmellington and is now eyeing further opportunities at Quantans Hill near Carsphairn; and Whiteneuk, south of Moniaive.
They want to put 35 turbines at Whiteneuk and 21 at Quantans Hill, each with blade tip heights of up to 250 metres.
Together, the projects could produce electricity to annually power about 300,000 homes.
There would also be battery energy storage facilities at each location.
Vattenfall has submitted a scoping report to the Scottish Government, launching the early stages of the Environmental Impact Assessment process.
And the company now wants to hear the views of the local community too to help shape their proposals.
UK development director for onshore wind Frank Elsworth said: “South West Scotland has the potential to become a green energy hub. South Kyle, Quantans Hill and Whiteneuk can play a major part in helping to power Scotland towards net zero and provide green shoots of recovery from the economic damage of Covid-19.
“Vattenfall wants to work with local communities, suppliers and partners to not only co-ordinate how our investments might benefit specific localities, but also to explore and create significant opportunities for South West Scotland.”
Over the coming months they will be liaising with community groups and representatives in each area to discuss the schemes and get feedback. Online surveys have also been set up and can be found, along with more information, at www.vattenfall.com/uk
