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 full SCVS report is available here.

You can read our full proposals, plus highlights from the 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 late 2018).  

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.

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.


The completion of the construction of the access tracks and foundations has signalled the start of the next phase for the construction team at Mynydd y Gwair.

The splitter islands at Penllegear roundabout have been removed and the route was successfully trialled on 21st August 2018.  Over the course of a month or so three vessels shipped all of the turbine components into Swansea port where they have been stored until their onward movement to site.

South Wales Police will escort up to two convoys per day, the morning convoy will be made up of up to three over-size components and the afternoon delivery will contain up to two.  It is anticipated that the first convoy will depart Swansea Port each morning at approximately 0930hrs with the second convoy departing Swansea port between 1200hrs - 1330hrs. The delivery of components will be subject to the availability of South Wales Police escorts and prevailing traffic conditions.

The abnormal load deliveries commenced on 23rd September 2018.   Since then we have delivered for 39 components successfully with more arriving each day.

The substation has progressed too, most of the external equipment has been installed within the palisade fence.  Work continues to install the internal equipment and the associated cabling.  Western Power Distribution are also undertaking their works to complete the grid connection ahead of energisaqtion.

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:
