Status: Completed

A planning application has been successful at Cefn Fforest Farm, Treharris for:

  • A single 500kW wind turbine with a tip height of 102 metres
  • An associated substation (6 metres x 3 metres)
  • A crane hard-standing, this will measure 20 metres by 35 metres and will be located adjacent to the wind turbine
  • A new access track of 293 metres will be created from the southern boundary of the land to the edge of the crane pad

  • Why is the development needed?

    • Help with the fight against global warming by displacing 500 tons of CO2 emissions every year
    • This site will produce approximately 1,713,000 kWh of electricity every year. This is enough to power over 500 average homes
    • The UK is currently dependant on the import of oil, coal, gas and electricity. This turbine will help with the UK security of supply

  • Why here?

    Identifying an appropriate site for a wind turbine is a complex and lengthy process. We strive to ensure our projects have the least possible impact on the local area and consider numerous factors before we decide to progress a project.

    • Good wind speed (6.5 metres per second)
    • Good site access
    • Minimal effect on locally and or nationally designated environments
    • A viable connection to the electricity grid
    • No impact on civil or military aviation
    • The ability to site a turbine an appropriate distance from homes


  • The Location

    The site is located in a rural area 1.1 km to the North West of Treharris and 2.09 km South East of Merthyr Tydfil.

  • Technical Considerations

    The location and proposal are informed by a wide variety of detailed technical investigations. The application has been submitted with a suite of documents including the following:

    • Heritage Assessment
    • Aviation and Communication Statement
    • Ecological Statement
    • Bat Report
    • Landscape and Visual Impact Assessment
    • Preliminary Risk Assessment
    • Noise Assessment
    • Planning, Design and Access Statement
    • Shadow Flicker Assessment
    • Transport and Access Statement

    These documents have been submitted with the planning application to Merthyr Tydfil County Borough Council, where internal and external consultees will be invited to comment on and review the information. We set out below a summary of the findings for key issues:

    A full noise assessment has been carried out and approved by Merthyr Tydfil County Borough Council. No dwellings will be subject to noise levels above nationally stated environmental health standards set out in ETSU-R-97.

    Shadow Flicker:
    A shadow flicker assessment has been carried out and was approved as part of the planning application. This shows that no dwellings in the proximity of the development will suffer from the effects of shadow flicker.

    A full Ecological Study was undertaken as part of the planning application. It concluded that the effects on local ecology were minimal and acceptable. Merthyr Tydfil County Borough Council agreed.

    Aviation and Ministry of Defence:
    No objections were received from either civil or MoD aviation in relation to the safety of aircraft.

    Archaeology and Cultural Heritage:
    An Archaeology and Cultural Heritage study was submitted as part of the planning application and approved. This concluded that there would be no unacceptable impact from the development.

  • Landscape & Visual Impact

    It is inevitable that the wind turbine will be seen in the surrounding area. A formal assessment of landscape and visual impact was undertaken in line with strict guidelines and it was concluded that the impacts were minimal and acceptable.
