About the Project

RES has started the process of developing a redesigned proposal for its consented Llanbrynmair Wind Farm, in Powys, mid-Wales, which will enable us to take advantage of modern turbine technology, and optimise the clean, low-cost electricity the wind farm will be capable of generating.

The new proposal is for up to 15 turbines at the same site location as the previous 30-turbine scheme which was approved by the then Department for Business, Energy and Industrial Strategy (BEIS) in 2021. Click here for more information on the site history and previous application. 

We currently expect to submit a new planning application in Winter 2025.

Based on our initial studies, the wind farm would comprise of up to 15 turbines with a tip height of up to 230m, resulting in an overall site generating capacity of 108MW. This is enough to power approximately 110,0001 homes with clean, low-cost electricity every year.

At this early stage, we have submitted a Scoping Report to Planning and Environment Decisions Wales (PEDW), whilst our site-specific surveys continue to inform the layout of the redesigned wind farm.

The Scoping Report and supporting information are also available on the Planning and Decisions Wales (PEDW) website here using the reference number: DNS CAS-03719-R0C2Z0.

1The homes figure has been calculated by taking the predicted annual electricity generation of the site (based on RES assessments Llanbrynmair has a predicted capacity factor of 37.7%) and dividing this by the annual average electricity figures from DESNZ (Department for Energy Security and Net Zero, formerly BEIS) showing that the annual UK average domestic household consumption is 3,239 kWh (Jan 2024).
