How Foel Fach Wind Farm could look from Cae’r Garreg
Pre-application consultation held for the proposed Foel Fach Wind Farm
Between 15 December 2025 and 9 February 2026 we undertook a statutory pre-application consultation on our draft plans for the proposed Foel Fach Wind Farm, a new wind farm on land to the north-east of Frongoch, near Bala.
During the consultation we invited feedback on our full draft planning application and held three public consultation events in Cwmtirmynach, Y Bala and Sarnau.
We are currently reviewing all feedback prior to submitting our planning application to Planning and Environment Decisions Wales (PEDW).
About Foel Fach Wind Farm
The 10-turbine wind farm could provide up to 72 MW of renewable electricity, enough to power over 68,700 homes.1
Since our informal consultation in 2024, and in response to technical feedback and surveys, we have made important changes to our project:
- The number of turbines has reduced from 11 to 10.
- One turbine has been moved to reduce the potential visual impact from Bala.
- Four turbines have been reduced in height from 220m to 200m to minimise potential visual impact from Eryri National Park.
72 MW x 0.36 CF x 8,760 Hours in a year/3.301 MWh. [1] Calculated using DESNZ’s load factor for onshore wind https://www.renewableuk.com/energypulse/ukwed/ Accessed 28/10/25
As Foel Fach Wind Farm would deliver over 10 MW of clean, renewable energy, it is defined as a Development of National Significance (DNS) under the Planning (Wales) Act 2015. The planning application will be made to Planning and Environment Decisions Wales (PEDW), which will examine the application and make a recommendation to Welsh Ministers, who then take the final decision.
Tackling climate change is one of the Welsh Government’s top priorities and increasing the supply of renewable energy is key to reducing carbon emissions. If it is consented, Foel Fach Wind Farm would contribute to the Welsh Government’s target to reach net zero by 2050.
