The final applications for 59.4MW Benbrack and 83.2MW Loch Urr windfarms are significantly smaller than originally planned.
The number of planned turbines at Loch Urr has been cut from 63 to 26, with 18 now planned at Benbrack rather than the original 27.
Eon said it made changes to the plans to reflect feedback it had received from local residents on the likely community and environmental impact of the scheme.
Eon project developer, Nick Taylor, said: “Since we introduced our proposals for both sites we’ve undertaken extensive consultation and held a number of events to share our plans giving local people the chance to provide their views and concerns.
“Having also taken guidance from Scottish Natural Heritage, we removed the northern section of our Loch Urr Wind Farm plans to significantly reduce the impact on neighbouring communities. Through local and environmental consultation the size of our Benbrack site has also been reduced.”
