Camilty Wind Farm • Relationship of turbines with backdrop and horizon; • Relationship with turbine size, scale and layout of other existing wind farms. 3.4.10 Other design considerations were taken from Reporters’ findings and statutory responses to other applications for wind farms in the area. In particular, during consultations in relation to proposed wind farm, SNH drew attention to the Harrow’s Law Appeal Decision Notice. The detail of this is considered in Chapter 9: Landscape and Visual, but in summary it stresses the importance of the A70 ‘Lang Whang’ road providing a boundary from the “empty and iconic” Pentland landscape to the south, and of preserving the views from the hill summits in the Pentlands and comparative scale of the landscape. It also refers to the effects of cumulative wind farm development in the area, with the Pentlands massif representing an important separating and contrasting feature within that context. 3.4.11 SNH’s recent objection to Harburnhead Wind Farm referred to the importance of ensuring that the current pattern and scale of wind development in the area is considered in design. In particular, other wind farm developments within approximately 25 km currently reduce in scale and size from west to east, approaching the Pentlands. This pattern is reflected in Black Law (54 operational turbines and 23 turbine consented extension), Tormywheel (15 turbines consented) Pates Hill (7 operational turbines) and Muirhall (6 operational turbines). Any acceptable wind farm in the area would need to be compact to be in keeping with landscape character and visual amenity whilst also fitting with the existing pattern of developments in the area to avoid impacting unacceptably on the views and visual amenity of users of the Pentland Hills. 3.4.12 In addition to turbine layout the location of wind farm infrastructure was also considered in the design process. 3.4.13 The integration of the wind farm in a landscape of commercial forestry and the potential for enhancement of the conifer plantations through diversification of species and structure forms part of the ongoing, long-term management of the forestry by the FCS. 3.5 Design Evolution Introduction 3.5.1 Following selection of the site, and employing the design criteria outlined above, the layout of the proposed wind farm evolved over a period of a year. This included the characteristics of the site and surrounding area, the predicted environmental impacts emerging from the technical assessments being undertaken, and the technical requirements of turbine efficiency and output maximisation. 3.5.2 Although a number of different changes were made to the turbine layout, the layout evolved over three main iterations which have been referred to in the remainder of this chapter as: 1. Initial Design – a 14 turbine layout including the forestry block to the west of the B7008; 2. Intermediate Design– an 8 turbine layout; 3. Final Design – a 6 turbine layout.

Camilty Wind Farm Initial Design 3.5.3 At this stage in the project the proposed site boundary encompassed forest blocks to the south east of the A70 and to the west of the B7008 as well as the main body of Camilty Plantation. 3.5.4 Within this boundary, the bulk site screening work carried out by PfR identified an initial design layout for the site. A feasibility study was then carried out to consider the potential of the site in more detail. The initial design layout and feasibility study identified that the site could accommodate up to 21 turbines of up to 3 MW. However, subsequent to the feasibility study, it was decided that land within the boundary to the south east of the A70 should be excluded from development due to landscape and policy sensitivities. This led to 7 turbines that were located to the south east of the A70 being removed, leaving up to 14 turbines on the remainder of the site. 3.5.5 In order to inform the layout of these potential 14 turbines information was gathered through a combination of desk-based study, including information from FCS records, and consultation. The exercise included: • Collection of wind speed data information from the NOABL UK Wind Speed Database; • Desk Based review of site constraints including ecology, ornithology and cultural heritage and associated consultation with the Forestry Commission Scotland; • Consideration Of likely grid connection options and arrangements; • Preliminary turbine delivery route assessment; • Provision of an indicative track and infrastructure layout; • Consideration of relevant planning policy; • Preliminary consultation with fixed link providers to identify fixed and microwave links; • Initial consultation with the Ministry of Defence (MOD), Civil Aviation Authority (CAA), NATS En-Route Limited (NERL) mapping tool and Edinburgh and Kincardine Airport; • Preliminary noise modelling and an initial ETSU-R-97 assessment; • Preliminary consultation with the following infrastructure operators: Scottish Power, Scotland Gas Networks and the Health and Safety Executive; • Preliminary consultation with SNH to determine proposed methodology for bat and protected species surveying; • A preliminary peat probing survey of the site; and • A preliminary Zone of Theoretical Visibility (ZTV) to 35 km radius and landscape capacity study. 3.5.6 This facilitated the creation of a constraints plan within which a potential developable area could be identified. This is discussed further below. Constraints Plan and Developable Area 3.5.7 A constraints plan was prepared showing the location and extent of known/recorded environmental constraints present on the site and its environs. Appropriate clearance buffers were applied to constraints where necessary in order to mitigate for potential direct impacts during the design process. The constraints were identified and refined throughout the EIA March 2013 3-8 ES Chapter 3 Design Evolution Copyright Partnerships for Renewables Development Co. Ltd 2013 ©
