Mynydd y Gwair Wind Farm

Wind energy from south Wales


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.

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:
