Butterfly / Glöyn Byw Solar Farm



Project Introduction

Butterfly / Glöyn Byw Solar Farm will be located to the south of Wrexham, adjacent to the A483, and between Johnstown to the west and Bangor on Dee in the East.

This proposal will be able to generate enough affordable, clean electricity to meet the needs of over 34,775 Welsh homes. It would also save over 2.3 million tonnes of CO2 compared to fossil fuel generation – that’s equivalent to taking more than 554,000 cars off the road for a year or planting over 39 million trees.

The integration of battery storage will also play a crucial role in ensuring that energy is available for when it’s most needed. This balances the grid to eliminate the issue of intermittency that can come with renewable energy generation, ensuring we can live in a future powered entirely by clean energy.

We place immense value on local input. Your feedback is integral to our process, and will help shape the final proposals.

The need for Solar

The UK is committed to achieving a fully decarbonised power system by 2030, a goal that hinges on embracing and expanding reliable, affordable, and clean energy solutions like solar power. In alignment with this, Wrexham Council, having declared a climate and ecological emergency in 2019, has set an ambitious Decarbonisation Plan, alongside a Local Plan that prioritises renewable energy generation. Projects like Butterfly/Glöyn Byw Solar Farm will contribute significantly to both local, and national climate commitments.

Public consultation

As part of our public consultation, we are holding five in-person events on:

  • Monday 29th September from 12-5.30pm at Johnstown Community Centre, LL14 2BE
  • Tuesday 30th September from 12-6pm at Rhostyllen Parish Hall, LL14 4AR 
  • Thursday 9th October from 5-7.30pm at Eyton Primary School, LL13 0YD
  • Friday 10th October from 1-6pm at Ruabon Village Hall, LL14 6AD 
  • Saturday 11th October from 10am-2pm at Piercy Hall, Marchwiel, LL13 0RH

The formal consultation will run for 6 weeks from the 15th September until the 27th October 2025, after which time we will carefully review the feedback received, make changes where appropriate and then look to submit a planning application to the Welsh Government later on in the year.

Project Manager

My name’s Robin, and I’m the project manager for the Butterfly / Glöyn Byw solar farm. I come from a wildlife conservation background, and am passionate about the natural world, having trained as an ecologist. Solar farms offer a unique opportunity to create vast, undisturbed habitats, free from intensive agricultural practices and pesticide/fertiliser use. I look forward to discussing the project in further detail with you.
