If you face towards Baumber, near Horncastle, you could be among thousands of people who will have sight of all eight turbines proposed in a controversial wind farm scheme, if it gets the go-ahead.

A new survey shows almost everyone living in a 30km radius to the north, west and south of the site – including Boston, Sleaford, and Lincoln – would see the turbines unless another building or trees near their homes happened to impede the view.

But many people living just a few miles to the east of the site, for example in Belchford and Greetham, or in the Bain valley around Horncastle, would not see the turbines because of the way the land lies.

"This is why we have been banging on about the need for Lincolnshire to wake up," said Melvin Grosvenor, chairman of Baumber Wind Farm Action Group (BWAG).

"The turbines are massive and will have a colossal impact.

"BWAG is not surprised by these findings. We have been doing our own research and knew what to expect.

"The turbines are huge. The diameter of the blades is wider than a Jumbo's wings and they are nearly as high as the pillars of the Humber Bridge."

There are also smaller areas of the county where some but not all of the turbines could be visible.

Enertrag, the Norfolk-based company behind the Baumber scheme, said calculations for the new visual impact survey were based on a 'bare earth' model. It took account of landform but not of any screening from buildings or vegetation.

There are also smaller areas of the county where some but not all of the turbines could be visible.

Enertrag is inviting comments from parish councils on the visual impact study by July 7.
