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 33.6MW. 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 application 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.

In the next couple of weeks the first 300 metres of track will be surfaced, a cattle grid and gate fitted  and the sides of the cutting will be hydro-seeded to establish some vegetation. 

In other areas the works to widen the public highway have been completed between A1K9 and ‘Five-Ways’ and this section has been reopened to the public.  Significant progress has also been made widening the final section of Heol y Barna between ‘Five-Ways’ and the junction with Heol Glyn Dyfal.  Most of this section has been widened and the base laid with a few small areas to be addressed over the coming weeks.  Once complete, the entire length of this section will be resurfaced and reopened.

Dawnus are working with the local community to minimise the disruption whilst these works are concluded.  All businesses within or adjacent to the closures are open as usual and can be accessed in accordance with the posted signs.

Dawnus and ourselves continue to liaise closely with the City and County of Swansea Council Highways Department regarding these works.

We would like to thank everyone for the patience and understanding during this period.

I have included details of the closures and their associated signed diversion routes below

Heol y Barna (from Five-roads to Heol Glyn Dyfal) – from approximately 17th July 2017 for 12 weeks

Recently I have hosted visits for both Tonia Antoniazzi MP and the Somerset Trust, it is a good opportunity to show what has been achieved to date and outline the steps that we are taking to minimise the impact of the works.  The visits have been well received and we have received positive comments from both.

Main Site

We are working closely with our civil and electrical contractors for the main wind farm site to develop and finalise the detailed design for all of the elements for the wind farm.

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:

Values are measured as Gross Value Added - a measure of the value of goods and services that an economy produces. During construction, the project could also potentially generate 104 Full Time Equivalent (FTE) jobs each year in Wales.
