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 7 weeks from the 15th September until the 3rd November 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. 

Frequently Asked Questions

  • Do RWE engage with the local community?

    Thorough and meaningful community engagement is at the heart of our approach to development. We seek to meet with local residents, organise consultation days, and present plans at an early stage to local stakeholders and groups as part of our consultations. We also regularly partner with local wildlife, school and community groups.

    Will there be a benefit to the local community?

    Yes, in addition to a £1.5 million community benefit fund to support community projects/initiatives, we incorporate new accessible/permissive footpaths, outdoor educational spaces, picnic benches, and new public green spaces like wildflower meadows and community orchards into our sites. We also seek to support local people/businesses when it comes to the construction and operation of our sites.

    Do solar farms create jobs, and do you hire locally?

    Yes. There are considerable opportunities for local suppliers throughout both the construction and operation phases of the site. Construction staff are also likely to use local accommodation and shops / restaurants, supporting the local economy. RWE also run an industry leading apprenticeship programme, helping future generations gain the key skills they need to participate in the transition to net zero/renewables. 

  • Is solar popular?

    Definitely. According to Government polling, solar is the most popular energy source, with over 80% of respondents stating they support it. When asked about a solar farm being built in their local area, a poll in 2022 found that a considerable 88% of respondents in said they weren’t opposed.

    Does solar PV work well in Wales? Is it sunny enough?

    Absolutely. Solar works well everywhere in Wales. Solar panels don’t need direct sunlight to operate and produce power during day light hours all year round.

    Is solar expensive?

    Not at all. Large scale solar is one of the cheapest forms of electricity generation, with costs expecting to drop even lower in the future given it does not need expensive inputs to operate.

    How does a solar PV installation work?

    PV panels are installed in rows on the land, usually separated by between 4-10m. This ensures grass can successfully grow underneath the panels and can be grazed by sheep. The panels convert light into electricity which is then distributed to our houses/businesses via the grid network.

    How long do PV modules last?

    The lifespan of PV panels is 40 years which is why we seek planning permission for 40 years on our sites. After this time the site is restored back to its former state, never losing its greenfield status in the process.

    What is the construction time?

    This depends on the size of the installation. A typical build time is around nine to twelve months for a typical project.

  • Are solar farms built with the landscape in mind?

    Absolutely, we work closely with communities to ensure that our solar farms blend in and restore traditional meadows and hedgerows to the countryside. The maximum height of our solar panels is three metres, which is the same as a well-maintained hedgerow. Extensive new hedgerow/tree and wildflower planting also helps local wildlife, in addition to screening views of the solar farm.

    Do solar panels create glint and glare?

    Solar panels are designed to absorb light not reflect it. The more light a panel absorbs, the more power it will generate. Modern panels are installed with an anti-reflective matte coating, to maximise efficiency, and reduce glint and glare that can be seen on older solar farms.

    Why are most solar farms built on agricultural land?

    Ground mounted solar is one of the cheapest forms of energy generation, with a fivefold increase in solar capacity is anticipated by 2030 in the Government’s Energy Security Strategy 2022. This cannot be achieved through rooftop and brownfield solar installations alone, as many domestic and industrial buildings either do not have roofs made of suitable material to support a solar system, do not have the infrastructure to export electricity to the grid, or simply present as an unaffordable solution, with initial costs of installation too high for some. As a result, agricultural land is used, without impacting on food security given the ability to still graze sheep/chickens on the farm. If we were to hit our renewable energy targets, we’d use just 0.3% of the UK’s land for solar farms, less than the land mass currently used for golf courses.

    Does land used for solar farms reduce food security?

    No. The UK Food Security Report states that climate change is one of the largest threats to domestic food production (with a 73% loss of ‘good’ quality farmland predicted by 2050 due to climate change), solar farms provide an opportunity to significantly reduce carbon emissions and tackle this threat. Solar farms provide valuable income for farmers and can still be used for grazing (sheep or chicken) due to the spacing between the rows of panels allowing a high-quality grassland to grow around/underneath the panels. There are many excellent examples of successful sheep and chicken farms across the country that run pastoral farms within an existing solar farm.

    How much space will solar farms take up?

    Very little. Even under 2050 Net Zero targets, Solar farms would occupy around 0.3% of the UK’s land – less that what is currently used by golf courses.

    Once built, will the development be noisy?

    Panels are generally static, so do not produce any noise. We undertake a full background noise assessment to ensure any noise that is generated is within acceptable levels. Any items which may generate noise are placed in the centre of the site, away from houses.

    Will there be much disturbance during construction?

    We aim to access sites and manage all traffic in such a way that it will have a minimum impact on surrounding communities We compose a construction traffic management plan which is prepared with the input from the local Highway Authority.

    Will there be fencing around the site?

    As is commonplace across farms on the countryside and in allotments, we install a deer fence (wooden posts and wire) around the site in order to keep it secure. The fencing includes mammal gates that will allow small animals to pass through, and our designs include green corridors to ensure free movement of wildlife through the site.
