Navitus Bay wind farm boundaries moved further from English coast

Navitus Bay Development Ltd, as a direct result of discussions with statutory consultees and local communities, announced in December 2012 a reduction to its proposed wind park in Poole Bay to cover an area of approximately 67 square miles.

The changes, which include moving the development further out to sea and making it smaller in scale, will reduce the potential visual impact of the project from key areas including Durlston Head, The Needles and Bournemouth.

The key changes include:

1) Moving the development boundary further away from the shore. The new project boundary is now approximately three kilometres further away from Bournemouth, Christchurch and Poole. As well as reducing potential visual impact, this will also protect navigational safety for vessels entering the Solent.

2) A 35% reduction in the maximum number of turbines that could be built from 333 to 218. Navitus Bay has narrowed the size of turbine options being considered, meaning that fewer would be built. This also means that the largest turbines will now be smaller than previously proposed, with a maximum height of 200 metres rather than 210.

3) An 8% reduction in the maximum overall capacity of the project from 1200 MW to approximately 1100 MW. In a typical year, the scheme could generate enough electricity for the domestic needs of the equivalent of around 775,000 average UK households (based on DECC figure of 4,370 kWh per household) and could avoid the emission of up to 1,150,000 tonnes of carbon dioxide each year (based on 339 grams C02 per kWh).

4) A 12% reduction in the total area of seabed that will be developed from 198 square km to 175 square km. This will mean less disturbance to the seabed.

Mike Unsworth, Project Director for Navitus Bay Development Limited, said “we have moved the site significantly further from the coast, reducing the potential visual impact and protecting navigational safety. In addition, we have reduced the maximum number of turbines in the proposal and reduced the height of the tallest turbine option.

“We feel that these significant adjustments to the plans strike a good balance between responses that we have had from consultees and the technical viability from an environmental, engineering and commercial perspective. The changes demonstrate that Navitus Bay is fully engaged in the debate and willing to listen.”

Keith Moss, Deputy Project Director at Navitus Bay Development Ltd, said “listening and acting on the feedback that we receive has always been important in informing our plans for the Wind Park. The changes announced today underline our commitment to genuine consultation. We are now looking forward to discussing the updated project with the community at our next round of consultation events in February.”

Huub den Rooijen, Head of Offshore Wind at The Crown Estate, said “The Crown Estate awarded Navitus Bay Development Limited the rights to develop the potential offshore wind resources to the west of the Isle of Wight.”

“As a core part of this they are engaging with local and national stakeholders to understand the impacts of the project. This is a key part of the Government’s statutory planning permission which must be granted before construction starts. Feedback gained to date has clearly fed into their plans for the project, demonstrating their sensitivity to the local area,” he said.

A series of public consultation events take place across Dorset, Hampshire and the Isle of Wight in February 2013.

The exhibitions will display new visualisations as well as an interactive 3D model of the site and onshore cable route.

The Navitus (navitas is ‘energy’ in Latin) Bay wind farm is expected to bring in excess of £100 million in contracts to the local economy. The project will create up to 1,000 local jobs during the four year construction phase, which subject to planning and consent, will begin in 2017, and 100 permanent jobs for the 20 year operational life of the project.
