The site layout has undergone several layout iterations of design as a result of ongoing technical studies, environmental surveys and assessments and stakeholder consultation.
Four of these layout iterations are shown in the figure above.
These include:
- 18 turbine layout, with a maximum blade tip height of up to 180 m
- 14 turbine layout, with a maximum blade tip height of up to 149.5 m
- 12 turbine layout, with a maximum blade tip height of up to 149.5 m
- 11 turbine layout, with a maximum blade tip height of up to 149.5 m.
Layout iterations
These revisions to the Proposed Development were made for the following reasons:
- To increase the distance of turbines from more sensitive locations to the north and west of the site
- To reduce the areas from where the turbines could be seen and reduce the number and extent and prominence of turbines visible when seen
- To reduce the extent of the wind farm across views
- To reduce the clustering and overlapping of turbines
- To create a more compact array of turbines
- To reduce the variation between the ground level of turbine bases.
Final proposed layout
The final proposed layout comprises up to 7 turbines with tip heights of up to 149.9 m. The reduction in proposed turbine numbers was due to not being able to find a suitable solution to mitigate the potential loss of ornithology habitat associated with a greater number of turbines.
