Galloper Wind Farm Substation
g) and h) have been addressed by locating the proposed transmission
compound next to GGOWF substation, within Sizewell Wents woodland, and
by locating the tallest (up to 14m high) building within the Galloper
compound to the south-east towards Sizewell Wents woodland and the
transmission compound. This 14m high building is necessarily located on the
southern side where the cable corridor exports electricity from the offshore
wind farm.
i) Finish buildings and structures in dull / neutral colour to minimise their
visibility and integrate them into the landscape. Avoid pale, bright and
reflective finishes.
j) Minimise widths of underground cable corridors through existing woodland
to minimise the loss of trees, by revised working arrangements.
k) Align cable corridors to allow for the creation of new woodland in an
arrangement that provides the most effective screening and landscape
mitigation. Trees cannot be planted above underground cable corridors.
l) Minimise lighting to that essential for operational and safety purposes.
Design lighting to minimise light spillage outside the site, glare and skyglow.
Design lighting in accordance with the best practice principles set out in The
Institution of Lighting Engineers Guidance Notes for the Reduction of
Obtrusive Light 2005.
m) Create and restore the hedgerow along Sizewell Gap road to provide
foreground screening to views from the road (to the south) and improve the
road verge for the benefit of wildlife.
n) Thicken scrub / woodland edge planting alongside the bridleway to the north
of the site to provide screening where it is necessary to remove trees due to the
construction of a cable corridor.
o) Provide planting, where achievable, on the east side of the substation to
screen the cable sealing end compounds and gantries, as well as the
substation, from the landscape and visual receptors to the east / north-east.
p) All plants and plant communities should be of locally native species / mixes
or appropriate to the landscape character of the Estate Sandlands landscape
character type and local biodiversity objectives.
All details will be agreed with Suffolk Coastal District Council at the detailed design
stage.
