What happened

Storm Darragh caused significant visible damage to the Porth Wen Solar Farm on the Isle of Anglesey, Wales, which was commissioned in 2024. EDF Renewables, which owns the 49.99MW site, confirmed the solar farm had sustained damage during the storm and said it was assessing the extent while conducting a controlled clean up. The company stated that repair work and the replacement of damaged panels was expected to carry on into early 2025, meaning electricity generation at the site was halted until at least then.

A full investigation was planned once initial recovery efforts were complete and the damage fully assessed. The storm also damaged a nearby wind turbine at a neighbouring green energy scheme in Llanbadrig, Anglesey.

Contributing factors

Storm Darragh, for which the Met Office issued a red warning covering parts of Wales and south-west England, struck a solar farm that had been commissioned only that year. The specific failure mechanism had not been reported at the time of publication and EDF Renewables said a full investigation would follow.

Lessons learned

  1. A solar farm commissioned in 2024 sustained visible damage from Storm Darragh, so operators should verify panel mounting strength against red warning winds before full output.
  2. Repair work and panel replacement after storm damage will continue into early 2025, so insurers should plan for extended loss of generation on new solar sites.
