Proposed Amendment to the Variation Application - November 2020 


In its consultation response of 18th August 2020 to the Energy Consents Unit (ECU), East Ayrshire Council (EAC) confirmed it has no objection to the Pencloe Wind Farm s36C Variation Application (June 2019) subject to an appropriate relocation of Turbine 1 (T1) and Turbine 2 (T2). The relocation is to mitigate for the adverse effects of overlapping/stacking when the wind farm is seen from viewpoints in and around New Cumnock to the north of the proposed wind farm site.

The Pencloe Wind Farm turbine layout has been reviewed from a landscape and visual perspective to determine whether relocating T 1 and 2 would beneficially alter the compositional appearance of the proposed development when seen from key viewpoints.

The proposed amendment is for the relocation of T1 and T2 and associated track and hardstanding infrastructure; T1 moving approximately 71 m west and T2 approximately 96 m to the north east.

PWEL are now (November 2020) submitting an amendment to the Variation Application, covering the proposed relocation of turbines.  An Environmental Information report, including a review of viewpoints, has been prepared to support the relocation of the two turbines.

The review of viewpoints has concluded that by relocating turbines T1 and T2, there will be a reduction in overlapping/stacking and an improvement to the composition of the wind farm turbine array as seen in local views. In particular, there will be beneficial effects to those viewpoints which will be seen by a greater number of receptors from in and around New Cumnock.

A further review has demonstrated that there is no material change to previously reported environmental effects, for example in terms of effects on ecology or noise, as result of relocating T1 and T2.

The amendment documents are available for inspection on this website, and the Scottish Government Energy Consents Website at         

Further Environmental Information Submission – March 2020

Consultation Responses to the Proposed Development

Pencloe Wind Energy Limited (PWEL) made a Further Environmental Information (FEI) submission to the Energy Consents Unit (ECU) of the Scottish Government on Wednesday 18th March.

Following receipt of the Variation Application the ECU consulted with technical and non-technical consultees to gather opinion from stakeholders regarding the merits of the proposed development.  Some matters have been raised by consultees that requires FEI to address and this submission provides the Applicant’s response to those.

The FEI Submission

The submission contains the following information:

  • An updated Planning Statement which reviews the latest Scottish Government climate change commitments, the climate emergency and summarises the consultation responses received and what has been done to address the points raised by consultees;

  • An updated Landscape and Visual Impact Assessment LVIA chapter addressing comments made by East Ayrshire Council and their landscape advisor, including replacement wirelines and new wirelines illustrating a microsited layout to minimise turbine stacking;

  • An updated Peat Slide Risk Assessment that meets the requirements of the latest Scottish Government guidance (2017). The assessment shows a low risk of peat slide over the site; and

  • Replacement tables setting out noise limits for noise sensitive receptors as it was identified that some tables in the noise assessment within the EIA Report contained errors.

The complete FEI submission is available under the documents tab of this website.


Following submission of the FEI, the ECU will again consult with statutory consultees and other interested parties and will look to receive responses by Monday the 20th April.

Consenting History

Pencloe Wind Energy Limited (PWEL) lodged an application for s.36 consent with the Scottish Government on 26 February 2015 for 21 turbines with a maximum height of 125 m to blade tip, with an installed capacity of around 69.3 MW. This application was the culmination of over two years survey and environmental assessment work over and around the Pencloe site.

On 21 September 2015, PWEL revised the application by deleting two wind turbines; micrositing another turbine; increasing the size of four on-site borrow pits; proposed an additional borrow pit and realigned the tracks and substation on site to avoid areas of deeper peat. This revised application was for 19 turbines with a capacity of around 62.7MW

East Ayrshire Council objected to the application in October 2016, and because of this a Public Inquiry was held in 2017 with the inquiry sessions taking place within the New Cumnock Community Centre/Town Hall between 25 and 27 September and the final session held on 31 October 2017.

In December 2018 the Ministers issued their decision to grant s.36 consent for 19 turbines of up to 125 m to tip with a total capacity of 62.7 MW.

The Variation Application


PWEL now wish to vary the Pencloe Wind Farm project to benefit from advances in turbine size and technology and hence increase the capacity and yield from that which could be achieved from the consented development.

The main design changes proposed are:

  • The tip height of the proposed turbines would increase from 125 m to up to 149.9 m;

  • The blade length will increase from around 50 m to up to 67 m; and

  • Turbines 6 and 15 have been relocated (to previous locations T1 and T2 in the Original 21 Turbine Design).


Amendments have also been made to the proposed track layout within the Application site, to accommodate the turbine changes as listed above.

The changes made to the consented development are summarised in the table below. For a layout of the proposed variation and the consented variation, see the 'Maps' page. 

The Application Process

PWEL is making the variation application under Section 36c of the Electricity Act 1989 to seek the consent of the Scottish Ministers to construct and operate a wind-powered electricity generating station and also gain their direction under section 57 (2) of the Town and Country Planning (Scotland) Act 1997.

In terms of the proposed variation development, EIA has been undertaken and an EIA Report is submitted in support of the proposed development. The likely significant effects of the proposed development, as set out in the EIA Report, are largely the same as the consented development.

The variation application was submitted to the Energy Consents Unit of the Scottish Government on Friday 21st June, and a copy of the Application letter and the Advertisement template are provided on this website along with the complete set of supporting documents. 

Following submission the Energy Consents Unit will consult with statutory consultees and other interested parties and will look to receive responses by the 14th August. 

Benefits Proposed v Consented

The benefits of the proposed development when compared with the consented development are important considerations that should inform the decision of Scottish Ministers. As noted above, and within the EIA Report, no additional significant effects are identified for the proposed development as were predicted for the consented development. The main benefits of the proposed development are summarised below:

  • The increase in energy yield would be in the order of 48 % when compared to the predicted energy yield of the consented development;

  • The increase in generation capacity would be in the order of 22.8 MW, which is around 36 %, when compared to the capacity of the consented development;

  • The proposed development with a capacity of 85.5 MW would more fully utilise the grid capacity that is available ( a total of 96 MW is available) compared to the 62.7 MW capacity of the consented development;

  • The proposed development will require around 20 % less aggregate for construction compared to the consented development;

  • The area required to be excavated for proposed development infrastructure is around 18 % lower than that which would be required to implement the consented development; and

  • The carbon payback period of the proposed development will reduce by 0.5 years to 1.5 years when the proposed development is compared to the consented development.
