Welcome to Parc Solar Traffwll

Welcome to the construction communications project website for Parc Solar Traffwll, a consented solar farm located on the west side of Anglesey, north west Wales.

The proposals, which were granted planning consent from Welsh Ministers in March 2023, will bring renewable energy to over 11,000 homes and businesses, securing a home-grown supply of clean, low carbon electricity in support of Welsh Government’s net zero target to meet 100% of Wales’s electricity needs from renewable sources by 2035.

Parc Solar Traffwll consists of three development areas, two which are south/south-west of Bryngwran, and one to the west of Llanfihangel-yn-Nhywyn. The development areas are linked by below-ground cabling, which connects to the grid at Caergeiliog to the west.

The construction phase of the project will formally commence in February 2024 and run for approximately 14 weeks. The project website will be updated on a regular basis to provide real-time information on the construction works and any potential impact on residents.

Public Drop-In Information Event

We held a drop-in event for members of the public to find out more and ask questions on the construction works process.

The event was held on Thursday 8 February between 2pm – 6pm at Caergeiliog Village Hall.

Latest Update

Construction officially commenced in February 2024, with initial works focusing on the cable route from the 12th February 2024 and lasting for approximately 14 weeks.

We are beginning the construction process by laying the cable connecting the main sites containing the solar farm with the electrical
substation on Cymyran Road, Caergeiliog.

This will require works to lay the cable in the road from the site, along a portion of Holyhead Road (A5) through Caergeiliog, and down a stretch of Cymyran Road. Consequently, Cymyran Road will be closed from Thursday 15/2/2024 to late March 2024.

Whilst every care is being taken to manage this process sensitively, we appreciate this will cause some disruption at times for existing road users and apologise in advance for any inconvenience caused.

This scheme will have an export capacity of circa 35MW – this is equivalent to:
