Navitus Wind Farm, Swanage

Christopher Chope Excerpts

Wednesday 4th July 2012 Commons Chamber

[Richard Drax (South Dorset) (Con)]

I am grateful to have this debate on an issue of great concern to people in my constituency and others along the coast. I welcome this opportunity to talk about a proposal that could change the character of our coastline for decades. The Navitus Bay offshore wind farm will cover 76 square miles of seabed owned by the Crown Estate. It is to be located to the south and west of The Needles on the Isle of Wight and will be clearly visible from Swanage, one of the seaside resorts in my constituency.

The project is a 50:50 joint venture between two foreign firms—the Dutch energy company Eneco and the French utility giant EDF. It forms part of round 3 of the Department of Energy and Climate Change’s programme of offshore development, which is designed to generate 33 GW of energy by 2020. Working at full capacity, the wind farm will generate enough electricity for about 800,000 homes. It will create jobs and foster engineering and marine-based skills, and it forms part of a regeneration agenda for some of the most run-down areas on the south coast. Put like that, and in the context of the Government’s enthusiasm for renewable energy, it seems almost irresistible.

However, Dorset and East Devon’s stunning Jurassic coast is the only natural UNESCO world heritage site in England. The Great Barrier reef has the same status, and if we were to suggest building 300 wind turbines off that, the Australians would tell us in typically blunt fashion exactly where to go. World heritage status was granted to the Jurassic coast 10 years ago in recognition of our glorious coastline, which UNESCO describes as being of “outstanding universal value”. It is a prized designation, and a magnet for 16 million visitors every year. Tourists spend nearly £700 million a year there and support more than 45,000 jobs. And yes, the unspoilt view is key to this success, so why are we considering jeopardising this jewel by siting a giant wind farm just offshore?

The precise details have yet to be confirmed when the three phases of public consultation are closed in autumn next year, but we know enough to be concerned. The aim is to generate between 900 MW and 1,200 MW of wind energy a year. That translates into a need for between 100 and 333 turbines. Each, depending upon capacity, will be somewhere between 150 and 210 metres tall. To put that in perspective, one of the larger turbines would dwarf the Gherkin in the City. Just one of these giant turbines would be significant; 100 of them, or more if smaller turbines are used, would blight the coastline for years to come.

Importantly, the proximity of this wind farm to our shoreline totally contradicts the Government’s own guidelines. The Department of Energy and Climate Change suggests that such developments should be more than 23 km from the coast. Unfortunately, the majority of this project is inside that limit. Indeed, the closest point is a mere 13 km away. Interestingly, there was, and presumably still is, the possibility of locating the turbines further out to sea. Originally, the Crown Estate earmarked a far larger area for the wind farm. Inevitably, the site chosen by Eneco and its partners is the closest to shore in depths of between 20 and 50 metres, which is clearly intended to reduce the cost. That would indicate, rather worryingly, that whatever the result of the public consultations there is little room for manoeuvre. The truth is that Navitus Bay will be too big and too close.

This is not just nimbyism. Those who think that a simple view should not impede our future energy requirements should think on this: UNESCO considered withdrawing the world heritage designation given to the beautiful and secluded site of Mont Saint Michel in France when it was threatened by just three wind turbines 20 km away. The French electricity firm involved quickly backed down and Mont Saint Michel remains undisturbed, surrounded by a permanent 40 by 80 km exclusion zone.

I have written to the UNESCO world heritage centre to warn that our own natural world heritage site is in jeopardy. It has written to the ambassador to the United Kingdom’s permanent delegation to UNESCO and to the advisory body of the World Heritage Committee. It has also demanded a visual analysis of the potential negative impact on the coastline. In the visual analysis I have seen, viewed from Durlston, a viewpoint in Swanage, a full third of the horizon is taken up by wind turbines. To be clear, that is the same Durlston that, following a £5 million restoration, is called the “Gateway to the Jurassic coast”. There would be a stretch of water between the land and the wind farm, but the undisturbed and peaceful skyline would be broken by man’s folly.

The Department of Energy and Climate Change has confirmed that Britain is still dedicated to producing 15% of the country’s energy from renewables by 2020, yet we know that wind energy generation has proved intermittent and unreliable. At peak output, wind farms average only a third of their proposed capacity, so wind energy has to be supplemented by conventional power stations or nuclear energy—not the stuff of green dreams—which are expensive to build and neither is renewable, but they will keep the lights on. Connecting Navitus Bay to the grid would be far costlier than anyone anticipated. The electricity networks’ strategy group reported this year on what it rather coyly describes as “regional connection issues”. Put simply, our networks cannot cope with carrying the extra capacity. The ENSG estimates that £450 million will need to be spent on “system reinforcement” in the south-west, which includes the proposed Navitus Bay development, before any electricity flows.

Then there is the vexed question of subsidies, to which my hon. Friend the Member for Daventry (Chris Heaton-Harris) has drawn our attention to so successfully. To make wind farms attractive, investors were lured with promises of excessive financial incentives, and 105 Members of this House have already protested against those subsidies.

[Mr Christopher Chope (Christchurch) (Con)]

I commend my hon. Friend for securing this debate and support him absolutely. The 105 signatures actually related to subsidies for onshore wind farms, but we know that the subsidies going into offshore wind are even greater and even less affordable for the taxpayer.

[Richard Drax]

My hon. Friend is absolutely right. I shall come to that point and ask the Minister to reassure me that the subsidy withdrawal will also apply to offshore wind farms. With households already struggling to pay their energy bills, the financial incentives for investors are almost obscene. The news yesterday that such subsidies will eventually be reduced to zero should deter companies hoping to exploit our energy crisis.
