Planning Application
RES has submitted a planning application for the 13 turbine Mynydd Maen Wind Farm to Planning and Environment Decisions Wales (PEDW) and the formal 5-week consultation period will commence on 14 April 2025.
You can view the planning application below. From 14 April 2025, the application can also be viewed on the PEDW website at https://planningcasework.service.gov.wales/ using the reference DNS/3276725.
A statutory consultation period will be advertised by PEDW, on 14 April 2025, to enable the public, as well as statutory consultees, to submit their comments on the proposal. These comments will then be assessed against the proposal and a determination made in due course.

RES has an Environmental Management System which actively encourages the reduction of paper consumption and promotes recycling where possible. To further reduce paper use, RES would prefer that the Environmental Statement (ES) is viewed on the project website or that copies of the ES are requested in USB format.
Hard copies of the full ES are available to purchase from RES at a cost of £250. Copies of the full ES are available on USB free of charge. Hard copies of the non-technical summary are available free of charge. Requests for documents should be made in writing, including payment if purchase of the full ES is required, to RES, Beaufort Court, Egg Farm Lane, Kings Langley, WD4 8LR or by email to graeme.kerr@res-group.com.
