Plans to replace 12 wind turbines on Kirkby Moor in South Cumbria with 6 larger ones have met fierce opposition.
RWE Innogy says the 20-year old wind farm needs upgrading.
But conservationists argue they'll be too visible from the Lake District National Park and the Site of Special Scientific Interest isn't right for them.
The existing turbines were installed in 1993 and are capable of translating the howling wind over some of Cumbria's most rugged moorland into 450 KW of electricity.
They're 45 metres and between them can supply up to 2,800 homes with electricity a year.
But technology has moved on a lot in 20 years.
Modern turbines are bigger and more efficient. RWE Innogy wants to replace them with 6 turbines of 115 metres.
South Lakeland District Council is still processing this planning application but we can reveal so far it's had around 600 letters of objection and 20 letters of support.
RWE Innogy says one of those letters of support is actually a consultation where around 800 residents and visitors of South Lakeland have lent their support.
One of the main objectors is Friends of the Lake District, which argues it's too close to the Lake District National Park and is a Site of Special Scientific Interest (SSSI).
The company says it will invest more money into managing the SSSI site and will increase its charitable giving scheme for the local area, if permission is granted.
It's expected to go before the planning committee in October, until then South Lakeland District Council's planning office is wading through the responses.
