Friends of the Earth claims the Davistow site is an unsuitable choice
A decision over a £75m wind farm on Bodmin Moor in Cornwall has been deferred by councillors.
The plans for the turbines at Davidstow will now go before the strategic planning committee with a recommendation they are rejected.
Residents have campaigned against the 20 413ft (126m) turbines, claiming they will dominate the landscape.
The plans, submitted by Community Windpower, will now be considered at a meeting on 19 August.
The environmental group Friends of the Earth, which usually supports green energy initiatives, has also opposed the wind farm on the grounds that the proposed site is too visible and too sensitive.
Community Windpower spokesman Rob Fryer said important decisions needed to be made about renewable energy targets in the UK.
Councillors also deferred a decision over an application by Windelectric Management for five turbines at Otterham, with a recommendation for its refusal.
