Summary

An extensive consultation process has taken place
involving both statutory and non-statutory consultees
and the public to ensure any concerns were addressed
as part of the EIA for the proposed development. The
EIA concluded that although there would be some
significant landscape and visual impacts in close
proximity to the site, the effects on the wider landscape
have been assessed as being not significant. The
project has been designed to maximise environmental
acceptability and reflects Cornwall Council’s policies
of encouraging appropriate renewable development
to maximise installed capacity. The EIA process
shows that overall the proposed wind farm has
been demonstrated to have generally minor adverse
environmental effects. The wind farm is designed to
operate for 25 years, at the end of which it would be
dismantled and the site restored thus all impacts are
expected to be completely reversible.
There is a clear and pressing need for more renewable
energy generation in order to decrease CO2 emissions
and reduce the UK’s reliance on imported fossil fuels,
with that need being stated in increasingly forceful
Government policy and ministerial statements.
National, regional and local planning policy provides
overwhelming support for renewable energy
development and projects that are in accordance with
policy and are sustainable should proceed. The Big Field
Wind Farm will make a significant contribution to both
regional and national renewable electricity targets,
and is compliant with policy from an international level
through to national, regional and local policy.
