Could massive solar farms damage the Gwent Levels?
The call comes as the Welsh Government considers a new application to build a solar farm on the ecologically sensitive Gwent Levels.
Planning and Environment Decisions Wales (PEDW) is currently reviewing the controversial Wentlooge Solar development. The proposed 318-acre site has sparked fierce debate, following damning evidence of environmental destruction caused by a similar solar project at Llanwern.
Geoff Devlin of Stop Craig y Perthi—a campaign opposing another proposed solar farm near Bishton—said: "To influence debate in the Senedd, people need to be aware of and discussing the key issues. There is now clear evidence of serious environmental damage caused by the Llanwern solar site, and people must pressure politicians. It's the only way to influence those in the Senedd."
PEDW is ruling on the Wentlooge site after operators RWE appealed a previous rejection under Development of National Significance (DNS) rules. The Welsh Government's 2019 declaration of a climate emergency may bolster RWE's case, as the site could be seen as contributing to climate policy goals.
The legal battle coincides with a Welsh Government-commissioned study into the Llanwern solar plant—built entirely within two Sites of Special Scientific Interest (SSSIs)—which revealed catastrophic impacts on wildlife and water quality.
Lapwing breeding pairs dropped from eight to two, with no successful nesting recorded in 2023. Shrill carder bee and brown-banded carder bee populations plummeted, likely due to herbicide use and failed wildflower planting. Bat activity declined sharply. The rare Eurasian crane, once seen as a hopeful returnee to the Levels, has vanished.
The report also highlights dangerous pollutants—including cadmium and lead—leaking into the reens and ditches, vital waterways that support otters, water voles, and rare aquatic flora. These findings were presented at PEDW hearings, raising urgent questions about whether mitigation measures can ever succeed in such a fragile ecosystem.
Gwent Wildlife Trust CEO Natalie Buttriss stated: "Mitigation has failed catastrophically. The proposed Wentlooge site is even larger than Llanwern and poses an even greater threat to this irreplaceable landscape."
Campaigners emphasize they are not opposed to solar energy, but argue that developments must avoid nationally protected areas. Only 12% of Wales is designated as SSSI, and these fragments, they say, should be sacrosanct. With vast areas of non-designated land available, they urge the Welsh Government to redirect solar projects away from sensitive habitats.
The Gwent Levels—often dubbed Wales's Amazon—are home to a rich mosaic of wildlife. Magor Marsh, a flagship reserve of Gwent Wildlife Trust, preserves one of the last remaining pieces of natural fenland in Britain. From cuckoos and warblers to kingfishers and wintering teal, the area supports biodiversity year-round. The reens, unique to the Levels, remain a haven for water voles—one of the UK's fastest declining mammals.
Public support for protecting the Levels is growing, with backing from naturalists Iolo Williams, Gillian Burke, and Lizzie Daly, and authors Julian Hoffman and Horatio Clare.
As PEDW prepares its decision, campaigners warn that approval could set a precedent for industrial-scale development on protected land.
Meanwhile, green energy giant RWE still operates lignite power stations in Central Europe. Lignite is a highly invasive and inefficient source of carbon energy. RWE has committed to phasing out all lignite sites by 2030.
