Two 100-metre-high wind turbines could be built on farmland in Undy.
Renewable Energy Systems (RES) has lodged the planning application to build the turbines near the M4 .
It says it will be the first wind energy project in the county.
The proposed 28-hectare site at Great House Farm is on grazing farmland, 520 metres from the nearest homes.
The scheme would produce enough electricity each year to meet the annual demand of at least 800 homes – equivalent to all the homes in Redwick and Rogiet.
The electricity will be fed into the local network at Caldicot pumping station substation where it can be distributed directly into local homes and properties by the local electricity supplier.
It could meet the average electricity needs of up to 1,600 homes, depending on which type of turbine is chosen, for 25 years.
A separate scheme for one turbine four kilometres away at Longlands Lane is being considered by Newport City Council.
Phil Grant, project manager said: “RES is pleased to have submitted proposals to Monmouthshire County Council for what could be the first wind energy project in the county.”
“The location of the turbines near the gateway to Wales would clearly demonstrate the council’s commitment to the Welsh Assembly and UK ambitions to generate 15 per cent of its energy consumption from renewable sources by 2020.”
A series of public exhibitions and consultations were held in September and newsletters sent to 8,000 households. Monmouthshire council is currently consulting further with the community and interested parties.
