The consultation is open from Thursday 13 August 2026 until 23.59 on Friday 2 October 2026.
During this period, we are consulting with specialist consultees, key local stakeholders, residents, community councils and local organisations, to help refine our proposals.
We will be holding three public drop-in events to share our plans and gather feedback about our proposals. Details of the events can be found below:

The proposals currently include up to eight wind turbines with a maximum blade tip height of up to 180 metres.
It is estimated that that the wind farm will generate up to 38MW of renewable electricity, which will be equivalent to the domestic needs of approximately 24,716 households.¹

As the proposed wind farm will generate over 10MW of electricity, it will constitute a Development of National Significance (DNS). This means Pennant Walters is required to make an application to obtain permission from Planning and Environment Decisions Wales (PEDW). More information on this process can be found here.
