Plans to build a 970MW wind farm off the south coast of England have been refused development consent by energy secretary Amber Rudd.
She rejected the bid by a joint venture of Eneco Wind UK and EDF Energy to build the 194-turbine Navitus Bay Wind Park between Dorset and the Isle of Wight.
Rudd agreed with the Examining Authority that the scheme should be refused development consent as its impacts outweighed its benefits.
She said in a decision letter that there would be significant adverse impact from the development on coastal views, as well as an effect on the use and enjoyment of the Dorset and East Devon Coast World Heritage Site.
The developers did not rule out a challenge to the decision.
Navitus Bay project director Stuart Grant said: “While we are clearly disappointed by today’s decision, we would like to thank the communities of Dorset, Hampshire and the Isle of Wight and all our stakeholders for the high level of engagement they’ve shown in the project, including their responses to our consultations and during the examination process.
“During the past five years the project team has carried out comprehensive stakeholder and community consultation.
“We will now discuss the options available with our shareholders and update stakeholders in due course.”
