The permit gives Drax licence to operate its proposed Abergelli Power gas project, subject to complying with the relevant national and European directives that set the requirements for environmental protection.
The decision was reached following consultation with the public and relevant stakeholders and is another step forward in the development of the project.
A separate decision to grant planning permission to the project is expected later this year.
Further details on the Environmental Permit granted to the project can be found on NRW’s website.
