Wind turbines – which could be among the tallest onshore in the world – are proposed to be erected outside New Cumnock.
Banks Renewables wants to erect the 11 renewable energy structures measuring 260 metres in height.
They would form an extension to the approved Lethans Wind Farm, which is already set to have the tallest turbines in Scotland with some measuring 220 metres.
The Lethans extension wind farm would lie about six miles from New Cumnock and about just less than six miles from Sanquhar, Dumfriesshire in forestry area.
The developer said it would “deliver a community benefit fund of over £9 million over its lifespan – while displacing more than 30,000 tonnes of CO2 annually.”
The wind farm extension would have a lifespan of up to 35 years.
Banks Renewables said it could provide enough power to generate "green" electricity for 87,000 people every year.
The huge turbines could be among the biggest sitting on land in the world.
It was claimed a turbine in Germany’s Gaildorf area was the tallest in 2017. That was 246.5 metres high – smaller than those proposed near New Cumnock.
The already approved Lethans wind farm will have 22 turbines. Five of those turbines would have a maximum tip hight of 220 metres.
Robin Winstanley, sustainability and external affairs manager at Banks Renewables, said: “Both Lethans and Lethans Extension will create a positive and long-lasting legacy for East Ayrshire, creating jobs and infrastructure improvements which will benefit the local communities for decades to come.
“We’re keen to hear the views of the local communities so we can establish the best way to work together to benefit East Ayrshire in the long term, while bringing Scotland’s Net Zero ambitions closer to reality.”
Banks Renewables has been carrying out consultation with the community.
It has submitted a scoping report to the Scottish Government’s energy consents unit on the plans.
