A planning application for an edge-of-town wind turbine, more than four times the height of North Walsham's most prominent landmark, looks set to blow up a storm.

Supporters say the turbine will help North Walsham play its part in the vital global need to produce clean, green energy, bring profits for community shareholders and help fill the coffers of worthy local causes.

But the formal application now lodged with North Norfolk District Council (NNDC) has unleashed a hurricane of opposition from a group which is calling for a public meeting and urgently wants to raise awareness of a structure members say will blight North Walsham and which could be seen from Norwich on a clear day.

The North Walsham structure would be about 10m taller than the Ecotech turbine at Swaffham.

Applicants Unity Wind Ltd want to site a three-bladed turbine with a tip height of up to 120m (nearly 394ft) on Grammar School Farm land east of Cromer Road, with the nearest building being the Norstead Hall Kennels.

The German-made Enercon E82 structure would dwarf North Walsham's ruined St Nicholas' Church tower which measures about 27m (90ft).

Unity Wind, a not-for-profit industrial and provident society, says the turbine, with a 25-year lifespan, would have a generating capacity of 2.3mw; enough to power 1,200 homes.

Secretary Alicia Hull said a raft of legally-required, professional and rigorous surveys had been carried out and while it was accepted that the scheme could have some landscape and visual drawbacks, they would not outweigh the benefits the turbine would produce.

She is appealing for people to register their backing for the scheme with NNDC and said if the plan was approved, she would be urging supporters to invest between �1 and �20,000 in the project, estimated to cost about �3.25m.

But Ian and Janet Harvey, who live off North Walsham's Happisburgh Road, and residents who live close to the turbine site: Bill and Brenda Hammond, of Lyngate Road, and Trevor Reynolds, of Wilds Farm, Antingham, are fiercely opposed to the scheme.

'Most people will assume it's one of those little wind turbines you see on farm roads which have no affect on anyone. I don't think anyone realises the monstrous size and impact of this,' said Mr Harvey.

The group, in turn, is appealing for opponents to register their concerns with NNDC.

They have also asked North Walsham Town Council to call a public meeting about the plan and said they would be putting fliers through letter-boxes throughout the town with a scale drawing of the turbine and its surroundings on one side and a ready-drafted letter of objection to the plan on the other.

? The consultation period is due to end on May 23.
