Plans are advancing for what could become the largest solar farm in Wales—situated in the Gwent Levels—with enough projected energy to power 100,000 homes.
400 MW of Green Solar Energy To be Produced

Future Energy Llanwern Ltd is leading an initiative near Redwick village, south of the Llanwern steelworks, that aims to produce enough sustainable energy to power more than 100,000 households.
According to Wales Online, this initiative has secured financial support from NextEnergy Capital, a major global solar investor managing $3.9 billion in assets. A formal consultation with the local community is slated for later this year. The project is expected to generate up to 400 MW of green solar energy, sufficient to power 108,000 households.
Linking to the National Grid
Extending across both Monmouthshire and Newport local authority jurisdictions, the proposed solar farm would link to the National Grid through a substation in Whitson. Future Energy Llanwern plans to release more details about the project—including its dimensions, expenses, and battery storage capacity—in the coming months.
Given its scale, the UK Government would classify the Llanwern solar farm as a nationally significant infrastructure project, with input from the Welsh Government. Over its anticipated 40-year operational life, the project also aims to allocate £10 million (£250,000 annually) from electricity sales toward local initiatives and provide complimentary electric vehicle charging stations for nearby residents.
Future Energy Llanwern stated that the project’s progress does not depend on future government energy price guarantees, though final funding decisions will be made closer to construction. The company also emphasized its awareness of the site’s environmental sensitivities and its experience implementing solar energy projects in the area.
Fully financed and owned by NextEnergy, the solar farm underscores the company’s dedication to environmental conservation, particularly given its location in the ecologically delicate Gwent Levels region.
Selecting the Solar Panels
Regarding the number of solar panels, the company noted that a specific model has not yet been chosen. Due to rapidly advancing technology, this decision will be deferred until the construction stage, making it impossible to determine the exact number of panels at this time.
Paul Griffiths, Monmouthshire County Council’s deputy leader, confirmed that the council will thoroughly review any planning application once submitted.
The council aims to position Monmouthshire as a leader in the green industrial revolution and will carefully weigh the development’s potential renewable energy contribution against its impact on the unique local ecology.
Other Solar Projects
NextEnergy also funded an operational solar farm in Llanwern, which is operated by a company that shares directors with Future Energy Llanwern: Elizabeth and Peter Vyvyan-Robinson. These directors are also attempting to revive another solar farm project in the Gwent Levels through Wentlooge Farmers’ Solar Scheme Ltd.
That project, involving 250,000 solar panels on a 129-hectare site, was previously rejected by the Welsh Government in 2021, despite an independent planning inspector’s recommendation for consent. The rejection was due to concerns from the then-Minister for Rural Affairs, Lesley Griffiths, about its impact on a landscape of significant historical interest.
However, a spokesperson for Future Energy Llanwern said that Welsh ministers have since acknowledged a legal challenge, admitting the previous application was unlawfully refused. This led to that decision being quashed, and the Wentlooge application is now set for reconsideration.
The development of Wales’ largest solar farm—supported by local and global investors — marks a significant milestone for sustainable energy production. If approved, it promises to power over 100,000 homes and benefit the region both economically and environmentally.
