The Government’s Planning Inspector has approved a planning application for eight 115m wind turbines and a substation at Carlton Grange, Thacker Bank, near Louth.
The application is known as the Gayton Wind Farm.
The District Council’s Planning Committee refused the application in June 2012 but it was approved by the inspector following an inquiry in January.
Portfolio Holder for Economic Regeneration at the District Council, Coun Craig Leyland, said: “We strongly feel that the inspector has made the wrong decision. Along with the community, the Council put forward what we felt was a robust argument for this not to be approved.
“The basis of the argument was the impact these 115m turbines are likely to have on the local area, affecting the quality of life for local people and landscape.
“We are already looking closely at the appeal outcome and considering what options are available to us.”
