Online Public Exhibition

RES believes in meaningful and effective consultation and we aim to engage early with the local community and key stakeholders in order to facilitate constructive consultation. This helps to identify issues and concerns, as well as benefits and opportunities, which we can then consider when developing a project.

As part of our community engagement on the proposed Mynydd Maen Wind Farm we launched an online exhibition on Tuesday 8 March 2022 to inform the local community about the proposal and gather comments on the proposal. The closing date for comments was 1st April 2022. Comments will still be accepted, however, they may not be taken into account in the design development for the proposal. Please contact us for more information.

Over the coming months, along with results of site surveys and assessments, we will take account of the feedback we have received as we refine the design for Mynydd Maen Wind Farm. Later this year, we propose to hold a second series of public exhibtiions to present an updated design for the wind farm, which will be held online and in-person (subject to Covid restrictions).  Further information will be provided on this page in due course.

The video below provides an introduction to the online exhibition and consultation.

Further information is provided below and hard copies of this information (including the comments form) are available upon request – please contact us for more information.

About the Project

Located approximately 1km west of Cwmbran and 2km east of Newbridge

The proposed site lies within a Pre Assessed Area for Wind Energy identified in Future Wales: The National Plan 2040 published by Welsh Government in February 2021

Environmental and technical surveys are underway in addition to consultation with relevant statutory bodies, stakeholders and the local community

Designed to generate reliable, renewable electricity, whilst minimising local impacts and maximising local benefits wherever possible

Capable of generating up to 63 megawatts (MW) of clean, green, low-cost renewable electricity

Equivalent to the electricity usage of around 63,0001 homes each year

Design Layout and Infrastructure

Early studies show an indicative layout of 15 turbines up to 149.9 metres tall, however, this may change as design evolves.

Turbine locations are designed around various constraints, including properties, slopes, watercourses, telecommunication links, sensitive habitats, overhead electricity lines and underground gas mains

In addition to the wind turbines and foundations, the site infrastructure is expected to include:

  • hardstand areas for erection cranes at each turbine location
  • a series of onsite tracks
  • a substation compound containing a control building and communications mast
  • a compound for energy storage
  • temporary construction compounds

Environmental Considerations

An Environmental Impact Assessment (EIA) is being undertaken to investigate any significant potential effects of the development on the environment and, where applicable, identify mitigation measures to eliminate or reduce potential effects. The EIA will include assessment of the following:

  • Ecology and Ornithology
  • Electro Magnetic Interference
  • Hydrology
  • Landscape and Visual
  • Archaeology and Cultural Heritage
  • Traffic and Transport
  • Socio-economics
  • Noise
  • Shadow Flicker

Supply Chain Opportunities

RES has a strong track-record of working closely with the local supply chain around its projects and maximising inward investment opportunities wherever possible

Mynydd Maen Wind Farm has the potential to deliver approximately £4 million to the local area in the form of jobs, employment , and the use of local services

RES is keen to hear from local businesses who are interested in learning more about the opportunities associated with the construction and operation of this project. Please contact us for more information

During the construction of Garreg Lwyd Wind Farm, Powys, RES appointed a local civil engineering company, Jones Bros, resulting in the project generating some £15 million inward investment, all of which was spent within mid and North Wales with £3 million invested in the immediate Powys area.

Over 21 further local companies, suppliers and accommodation providers were utilised, and the project also sustained employment for 95 people all of whom were from within 70 miles of the site.

In addition, Jones Bros were able to add seven apprentices, to their annual training programme, as a direct result of the wind farm contract.

What Would the Wind Farm Look Like?

We have produced indicative wirelines to help give an impression of what the wind farm could look like from a number of different viewpoints in the area. Click on the links to view.

Viewpoint 1 - Twmbarlwn Viewpoint

Viewpoint 2 - Old Pant Road, Newbridge

Viewpoint 3 - Meadowside, Cwmbran

Viewpoint 4 - Presoch Lane, Penyrheol

Viewpoint 7 - Monmouthshire Brecon Canal

Viewpoint 10 - Ridgeway

We have also produced an indicative Zone of Theoretical Visibility (ZTV) Map showing where the turbines could be visible from. Please note that this is based on bare land form without trees or buildings.

Traffic and Transport

Access is one of the key considerations when selecting a potential wind farm site, particularly with regard to the turbine deliveries

The preferred access point and turbine delivery route are shown on the map in the middle

Over the next few months, we will consult with local authorities, the emergency services, the local community and other relevant bodies on our transport plans

                                 Click on image to enlarge

A transport assessment will be undertaken as part of the Environmental Impact Assessment (EIA) process and, if the wind farm is given consent, a detailed Traffic Management Plan will be agreed with the highways authorities and the police

Wherever reasonably practicable we will use materials available on site and source construction materials locally in order to help reduce traffic movements.

Common Land

The proposed wind farm is located solely on Common Land

A secondary application will be submitted to deregister the area of common land on which the turbines, tracks and substation would be situated and to provide replacement land so that the overall area of common land is not reduced.

This application will be submitted at the same time as the wind farm application

Engaging with Mynydd Maen Commoners Association

Development and design of the wind farm will be carried out in consultation with users of the common to ensure the ongoing grazing and management of the common are supported

Why Wind?

Urgent need to accelerate decarbonisation

Tackling Climate Change by supporting Wales Energy Strategy, which has a target of Welsh renewables to generate electricity equal to 70% of Wales' consumption by 2030

Enables us to generate our own electricity reducing reliance on imports

Not subject to sudden price fluctuations or the uncertainty of global markets

Renewable energy at lowest cost to the consumer2

Free and inexhaustible resource which has an important role to play as part of a balanced energy mix

1 The homes figure has been calculated by taking the predicted annual electricity generation of the site (based on RES assessments Mynydd Maen has a predicted capacity factor of 41%) and dividing this by the annual average electricity figures from the Department of Business, Energy and Industrial Strategy (BEIS) showing that the annual UK average domestic household consumption is 3,578 kWh (Dec 2020).
