Mynydd y Gwair Wind Farm

Wind energy from south Wales

Construction of innogy’s Mynydd y Gwair Wind Farm set to start

Mynydd y Gwair onshore wind farm is now under construction in South Wales, 15 km north of Swansea. Once operational, the 16 turbine project will have an installed capacity of up to 32.8MW. The project is expected to be a significant investment and could create up to 104 equivalent full time jobs on average during each year of its construction and deliver £8.5 million to the local economies of South and West Wales1.

Information about the construction of the project will be exchanged at Community Liaison Group Meetings and also made available on this web page and on our Mynydd y Gwair Wind Farm e-newsletter. We are keen to keep people up to date on our activities. If you would like to sign up to receive project newsletters about Mynydd y Gwair e-newsletter, please email us directly.

Community Investment

Working with communities

Once fully operational, Mynydd y Gwair Wind Farm will bring with it community funding of £240,000 per annum over the operational lifetime of the wind farm, likely to be up to 25 years.
This flexible funding has the potential to significantly benefit communities both very local to the project and more widely across Swansea.

Proposals for the Community Fund

In 2014 innogy consulted on our proposals for the fund with some key local stakeholders. We also commissioned Swansea Council for Voluntary Service (SCVS) to undertake a more detailed consultation exercise with communities within our proposed area of benefit for the local fund. The 2014 SCVS report is available here.

In 2018 a second consultation was commissioned within the Mawr Community Council area only as the two original consultation events in Mawr were postponed. PMDevelopments, was invited to work with Mawr Community Council and carry out this additional consultation. The findings of this second consultation project have been written up into a report which, where possible and appropriate, compares findings to and combines data with the results of the 2014 consultation and is available here.

You can read our full proposals, plus highlights from the 2014 consultation, along with more information about our next steps in developing the fund here:

Community Fund Administration

innogy is pleased to announce that the contract to administer the Mynydd y Gwair Wind Farm Community Fund has been awarded to Swansea Council for Voluntary Service (SCVS). The fund, worth in the region of £6million over the expected 25 year operational lifetime of the project, will be open for applications once the wind farm is fully operational (likely Spring 2019).  

With a membership of over 250 local organisations, SCVS is the umbrella body for the third sector in Swansea. SCVS offers advice, guidance, information, development, training and representation services on all issues linked with voluntary activity.  Throughout 2018, SCVS will work closely with innogy to continue developing the structure of the community fund.  If you would like to be kept informed about the development of the community fund you can register your interest with SCVS by contacting Alyx Baharie, Development Officer, by email:, or call 01792 544005 or write to: SCVS, 7 Walter Road, Swansea, SA1 5NF.

Applications are now open for the grants panel members for Mynydd y Gwair Wind Farm Community Fund. The Fund will become available once the wind farm is fully operational. Ahead of this, Swansea Council for Voluntary Service are looking for volunteers to join the grant giving panel. The deadline for applications is January 22nd 2019.  Details can be found on Swansea website.

Construction Update

Project Manager, Tim James, will post regular updates on the construction of Mynydd y Gwair Wind Farm here.

Construction Project Manager’s Blog

Welcome to my Blog. During the construction of Mynydd y Gwair wind farm I will regularly update my blog to outline what has been happening on site, any upcoming events and share some progress photographs.


Following on from my news in February that we had achieved our first generation from the site I am now pleased to say that all of the components have been transported to site and the final wind turbine was erected today (19th March).  The crane will be dismantled over the next few days and leave site.

I would like to take the opportunity to thank the local communities along the delivery route for their patience during the wind turbine component delivery period. It has been a significant challenge to erect the turbines through the winter but the challenges have demonstrated what a perfect site Mynydd y Gwair is for a wind farm!

12 turbines are now fully commissioned and generating with the next one due any day now!

Our next major milestone will be to get all 16 turbines up and generating renewable energy to the grid. At which point our much awaited Community Benefit Fund, worth in the region of £6M also becomes available. This is being administered independently from innogy by SCVS and we are excited to see the impact it will have locally.

During the next month or so we will reinstate the two splitter islands on the Penllegaer roundabout  and we will undertake final top-soiling and seeding around the turbines.


We have set up a text messaging service to keep you informed of what we are doing. This provides a fast and efficient way of keeping you updated with key construction activities, deliveries and information on our community benefit fund. If you would like to be contacted in this way please rgegister your mobile telephone number by texting your name and the acronym: MyGWF to 88882 or email us with your details.

Community Liaison Group

As part of the development, innogy established a Community Liaison Group which has met regularly since November 2016 and will continue to meet regularly throughout the construction period, until the turbines are operational, probably towards the end of 2018.  

The Community Liaison Group is an information exchange, giving innogy the opportunity to update members on progress, share construction plans, and providing other representatives with a forum in which to raise questions.  

The four community councils most affected by the development have nominated representatives, as have the West Glamorgan Commoners Association, South Wales Police, Dawnus, and the planning and highways departments of Swansea City Council.

The representatives nominated by each community council, and the representative of the West Glamorgan Commoners’ Association, are:
