Peel Energy is considering submitting an application for a wind farm with 21 generators on marshes in Frodsham.
Parent group Peel Holdings owns extensive land in the area as part of its Manchester Ship Canal estate.
It already has consent for a massive waste-fuelled power station and business park, branded Ince Park: Resource Recovery, between the Shell Stanlow plant and Runcorn. The Ince Park incinerator plans were passed after public inquiry despite local objections on air pollution grounds.
The Frodsham wind turbines would be 410ft tall. The plans were announced at the planning committee meeting of Cheshire West and Chester Council on Tuesday.
Richard Dibley, senior development manager from Peel Energy, told the meeting the company would start its community consultation process soon. A planning application is expected to be submitted in November.
