Harestanes South Windfarm Extension


Located in the National Forest Estate of Ae, South west Scotland, within Dumfries and Galloway, the site lies to the south of the operational Harestanes Windfarm.

Current Stage

ScottishPower Renewables (SPR) has submitted a S36 Application to the Scottish Governments Energy Consents Unit for an extension to add around 45MW of generating capacity to the existing operational Harestanes Windfarm.  

The proposed design has been reached following feedback from consultees and communities. A comprehensive suite of environmental surveys has also informed the proposed design including local ecology, archaeology, hydrology, ornithology and access. Turbine positions and associated infrastructure have evolved through an iterative design process to achieve a final layout sympathetic to environmental constraints and the surrounding landscape.

Copies of the submitted documentation can be found below in the 'Documents' section.

Following identification of a previously unknown telecommunications link, SPR are preparing an Addendum to the Section 36 Application for submission to the ECU in summer 2022. The purpose of the Addendum will be to re-locate a turbine by 64m, to outwith the zone of interference of this telecommunication link. The Addendum will also contain updated cumulative landscape and visual assessment.

Project History

This project is a result of SPR’s partnership with Forestry and Land Scotland, where SPR has rights to investigate the feasibility of onshore renewables projects within the National Forest Estate in South West Scotland.

SPR completed construction and began operating Harestanes Windfarm in 2014 and has identified the area to the south of Harestanes Windfarm as having excellent potential to be an extension to this site.

In July 2020 SPR installed a met mast at Brownmoor Hill to gather data on wind conditions at the site.

Planning permission has been granted for a further met mast at Main Rig to provide further information about wind conditions across the site.

Community Consultation

Early consultation is key to the way SPR develops projects, and throughout the process SPR ensure local communities and stakeholders are given the opportunity to provide feedback.  

In May 2020, a local leafleting and newspaper advertising campaign was carried out in the local area to ensure residents were kept informed of project progress.

A second public consultation exercise was undertaken in September 2020 in the form of an online Virtual Public Information Event.  This event was promoted through local leafleting and newspaper advertising.  The event presented how the design of the proposal had evolved to take on board public and consultee feedback as well as the findings of the completed environmental studies and assessments.

Benefits and Enhancements

As a responsible developer of renewable energy, SPR is keen for the communities surrounding this project to benefit. SPR are working with Forestry and Land Scotland to develop innovative community benefit options.

With established sites nearby, SPR has a history of working positively with communities within the region. SPR is keen to ensure employment and the business skills required to maximise economic benefits can be delivered locally to ensure those who live near our sites benefit. The Harestanes South Windfarm Extension has proposed:

  • A Habitat Management Plan which will implement positive land management for the benefit of landscape and nature conservation, focusing on Peatland Restoration and Broadleaf planting
  • Electric vehicle charging points in the Ae Forest carpark*
  • Financial support to facilitate the purchase of E bikes for rental at the Recreational Centre*
  • Promotion of family friendly / beginner biking routes or horse-riding routes around the proposed windfarm using existing and upgraded forest tracks*
  • Provision of a shelter with tools for bike maintenance and a place to shelter / picnic within the windfarm*
  • Provision of information boards regarding the Proposed Development*
  • Financial support for the employment of seasonal ranger to assist with the management of core footpaths in the area.

The Socio-economic assessment for the Harestanes South Windfarm Extension predicts that:

  • During construction the proposed Development could support, in net terms, approximately 52 jobs in Dumfries & Galloway and an estimated 155 jobs nationally (for Scotland as a whole)
  • During the operational phase, the proposed Development is expected to require between 3 and 5 new full-time employees (engineers and technicians) at the local level. Additional benefits would accrue to the local supply chain as a result of services supplied to the operation of the proposed Development.
  • The local economy would be expected to be boosted by a total of £3 million of net Gross Value Added (GVA) during the construction period. The Scottish economy would benefit by some £9.2 million net GVA.
  • During the operational phase (assessed over a nominal 40 year life) the proposed Development would contribute lifetime GVA of just under £19.4 million to the local economy through direct, indirect and multiplier effects, and over £26.8 million to the economy of Scotland as a whole.
  • The annual generation from the proposed wind turbines is estimated at approximately 102(1) gigawatt-hours (GWh).  With potential to supply enough electricity to meet the domestic needs of up to 27,500(2)
