GALLOPER WIND FARM SUBSTATION
16.0 Summary and Conclusion
16.1.1. The assessment process has sought to define the full extent and
nature of the likely landscape and visual effects arising from the
construction of the onshore cable connection and substation
associated with the GWF.
16.1.2. The effects on landscape character and visual amenity result from two
main changes, the removal of a central part of an existing woodland
(Sizewell Wents) which is a feature in the landscape, and the
introduction of the substation and associated works including a
profiled landform and substantial new woodland planting. Removing
part of Sizewell Wents will also open up views of existing pylons and
the existing GGOWF substation until new planting matures and
provides some screening. The proposed development will occur in the
context of the existing substation, pylons and Sizewell Power Station
which will limit effects to some degree.
16.1.3. The proposed development with the ‘additional mitigation area'
discussed in section 8.1.1 would lead to similar effects as those
assessed without the ‘additional mitigation area'. While the landform
with the ‘additional mitigation area’ would be slacker and tie into the
existing landform north of Sizewell Gap road more gradually,
bringing local benefits to landscape character and views, the overall
extent, magnitude and significance of effects on receptors would be
similar with or without the additional landform.
16.1.4. Landscape and visual effects of the onshore cable connection will be
limited to the construction phase which will be relatively short term.
Effects at Years 1 and 15 will be Negligible.
16.1.5. The main effects will be associated with the construction and
operation phases of GWF substation and connection to the National
Grid and these are summarised below and also, for the operational
phase, in Tables 4 and 5.
