The future of a wind farm project which has divided a community is being decided by councillors on Wednesday.

Plans for a community-owned wind farm in Watchfield, Oxon, were approved five years ago, but developers are now seeking permission for larger blades.
The wind farm would supply electricity to almost 4,000 homes.
Some local people say they are worried about the impact on the landscape and the effect on students at a nearby school for autistic children.
The company behind the proposals, Westmill Wind Farm Co-op, has been nominated for the best business in the South East Renewable Energy Awards 2004, and will find out the results in early November.
Adam Twine, from Westmill Wind Farm, said earlier this month: "Bangladesh suffered some of the worst flooding ever this year, leaving 30 million people homeless.
"This is just the beginnings of the effects of climate change.
"The imperatives to respond creatively and urgently to climate change is beholden on us all as individuals, communities, and decision makers."
Teachers at the nearby Pennyhooks Project education centre say their autistic students suffer from sensory overload, and may find the blades distracting and distressing.
Other anti-wind farm campaigners say the turbines spoil the landscape and are responsible for killing birds.
