ESB is developing proposals for Millmoor Rig Wind Farm

Project Summary

The site is located in the Scottish Borders, within a large area of commercial forestry in the Wauchope Forest. View the Location Plan for a detailed map of the site location.

After taking into consideration responses to our Section 36 application stage proposals from statutory consultees and the local community, as well as information collected from environmental surveys, we have undertaken a series of design iterations and refined the layout of the proposed development.

The Millmoor Rig Wind Farm proposal comprises:

Up to 13 turbines, with a maximum height ranging from 180m to 230m, and a generating capacity in excess of 50MW. View proposed Additional Information layout here. Changes to the layout include the movement of T9, T11 and T13 in response to consultee comments.
Updated track alignment to include a new watercourse crossing of the Carter Burn in response to Historic Environment Scotland.
Plans to co-locate approximately 20MW battery storage wind farm to maximise the use of the grid connection
On-site access tracks linking the turbines and connecting to the A6088 road via a mixture of new and existing roads, using the route of an existing forestry track
On-site grid substation
Site office and staff welfare facilities
An offer of a Community Benefits Package and Shared Community Ownership

Early Stage Development

In May 2022, ESB received an Environmental Impact Assessment (EIA) Scoping Opinion from the Scottish Government, which sets out the range of environmental studies that need to be undertaken in order to both shape the design and assess the impact of the project.

ESB submitted an application for planning consent to the Scottish Government’s Energy Consents Unit in November 2022, and subsequently submitted Additional Information to address consultee comments on 24th September 2025. The formal consultation period for the Additional Information submission is now open, and will close on Monday 27th October 2025. All planning application documents can be accessed via the ECU’s website, or can be viewed and downloaded here.

Project Background

The location of the proposed Millmoor Rig Wind Farm, within an area of extensive commercial forestry, is broadly similar to that proposed for another wind farm development known as Highlee Hill Wind Farm. However, Millmoor Rig Wind Farm is an entirely new proposal and ESB has no connection with either the former Highlee Hill Wind Farm proposal, which was withdrawn from planning in May 2017, or its developer.

In deciding whether to progress with its proposals for the Millmoor Rig Wind Farm, ESB carefully considered each of the consultee responses and representations to the Highlee Hill Wind Farm planning application.

Landscape and Visual Assessment

A digital Zone of Theoretical Visibility (ZTV) model (attachment 5) was created to illustrate the geographical area within which views of development are theoretically possible. This is based on a 'bare-earth' scenario, whereby the screening effect of areas of existing vegetation or built features in the landscape are not taken into account.

The ZTV shows the 21 viewpoint locations included LVIA. The viewpoint locations are located at a range of distances and directions from the Proposed Development, are at varying elevations and cover a variety of different character areas and types. Some of the viewpoints are intended to be representative of the visual experience in a general location whereas other viewpoints illustrate the view from a specific or important vantage point.

Environmental Impact Assessment

As part of the development process we must undertake an Environmental Impact Assessment (EIA) to assess the effects of the development on the natural, physical and human environment.

The number, size and layout of the turbines has been determined by environmental, technical and commercial constraints identified during the EIA and iterative design processes. Depending on final turbine selection, a potential generating capacity of approximately 78 MW with 20 MW co-located battery energy storage is proposed.

The EIA, which is published in an EIA Report, will cover topics including landscape and visual amenity; traffic and highways; noise; ornithology and ecology; archaeology and cultural heritage; geology, hydrogeology and hydrology; forestry; and socio economics. Consultation with statutory and non-statutory authorities and with the public is a key part of the EIA process.

ESB has appointed RSK Environment Ltd (RSK), an experienced environmental consultancy, as lead consultant to carry out the EIA and related assessments to accompany a Section 36 application to Scottish Ministers.

Public Consultation

ESB are hosting a public information event on Wednesday 11th June 2025 at Southdean Village Hall, Southdean, TD9 8TH from 1pm – 7pm. This is to present updated plans and proposals, and answer any questions on the upcoming Additional Information submission.
ESB Held two public consultation events in Southdean and Bonchester Bridge, on 16^th June and 17^th June 2022. The public consultation was held in order for the public to comment on the proposal as it moves through the design process.
Public Information Days took place in Southdean Village Hall on Wednesday 18^th January 2023 and Bonchester Bridge William Laidlaw Memorial Hall on Thursday 19^th January 2023.

The Benefits of Millmoor Rig Wind Farm

The development of Millmoor Rig Wind Farm would bring several important benefits at both the local and national levels spanning the environment, economy and community.

Major positive impacts on the environment, providing clean, renewable energy, and helping the Scottish Government reach its target for net-zero carbon by 2045 and interim 2030 targets
Supporting the local economy via contracts for tender and local construction spending
Community benefit funding of £5,000 per megawatt installed generating capacity, shaped to local needs, over the lifetime of the project if consented and constructed.
