Mary Smith of New South Law, which acted on the landowners’ behalf, said her clients had been “vindicated”.
She added the case would have implications for other communities affected by infrastructure projects from energy schemes to road-building in future.
“Your home is your sanctuary. That sanctuary has been disrupted over and over again by an energy company that has shown minimal regard for our clients’ welfare, the impact on their businesses and family life, and the safety of their livestock,” she said.
“It should not have taken a high court case brought by a community group and charity on behalf of hundreds of landowners and occupiers to make sure developers comply with the law. Adequate regulation should be in place to govern energy company behaviour and to protect the public.”
A Green Gen Cymru spokesperson said they acknowledged the court’s judgement, which provided a “clear basis for future conduct and engagement”.
They said: “As we have consistently said, our preference remains to work collaboratively with landowners and stakeholders, and we will continue to prioritise dialogue, cooperation and voluntary agreements wherever possible.
“We are committed to carrying out our work responsibly, maintaining high standards of engagement, biosecurity and environmental care as we support the development of the infrastructure needed to deliver a secure and resilient energy network for Wales.”
