Plans for a windfarm between the villages of Boxworth and Connington have been unanimously rejected by South Cambridgeshire District councillors.
Campaigners say that they are "delighted" at the decision
At a meeting on Wednesday council members rejected the plans.
Local residents from the Stop Cambridge Wind Farm Group have been campaigning against the windfarm since the plans were submitted last August.
The application for 16 330ft tall wind turbines was put forward by Suffolk-based firm Your Energy.
Company can appeal
All 28 members of the council's development committee voted against the plans.
Mike Barnard, spokesman for the Stop Cambridge Wind Farm Group, told the BBC: "Planners had recommended refusal on a number of grounds.
"Those grounds were fairly serious including A14 safety, noise, landscape, the effect on wildlife and Cambridge Airport objected due to problems with radar.
"Each of those is grounds for refusal in their own right."
The company has three months to appeal against the decision.
