Developers of the wind farm which would be sited off the Dorset coast have announced further changes to the boundary which remove the northernmost part - the 'top triangle'- altogether.
Previous changes to the northernmost boundary were made in December 2012 following navigational concerns from the RYA.
These latest changes will move the site up to 3.8km further away from the shore and are in response to feedback received from the public and statutory consultees during the final round of consultation last year.
The development will now cover an area of 155 km², compared to 175 km² under the previous boundary and the maximum number of turbines that will be built, assuming the use of the 5MW model, will fall from 218 to 194.
If the wind park is granted development consent, with the new boundary it will have a maximum installed capacity of 970MW, generating enough low carbon energy to power approximately 710,000 homes
Mike Unsworth, Project Director at Navitus Bay, said: "We have always listened to and acted upon the feedback we receive from our public consultations and our statutory consultees.
"We hope that local residents and statutory consultees who have expressed concern about the wind park will welcome today's announcement.
The boundary change is significant, and balances the need to reduce visual impact while ensuring that the project continues to make an important contribution to sustainable energy generation in the UK and to the local economy in the shape of jobs and investment".
