Work to start on £7.5m Heysham South wind farm

Work is due to start on a £7.5m wind farm in north Lancashire.

Geological investigations will be carried out at the Heysham South wind farm before three 125m high (410ft) turbines are put up in the summer.

Banks Renewables said the wind farm would produce enough renewable energy for about 4,200 homes.

The RSPB has raised concerns about the impact the turbines will have on the pink-footed geese population in Morecambe Bay.

Development director of Banks Renewables Phil Dyke said: "It's a nationally important special protection area, so we did over two years of bird surveying.

"We worked with bird groups and the flight lines for birds were studied from the coast to feeding areas inland."

Lancaster City Council granted planning permission in October for the site which will be situated on agricultural land to the south of the A683.
