Britain’s largest biomass plant, to be built in Wales, has been given the green light by the UK’s Environment Agency.

The Prenergy plant, which will burn wood chips to generate enough power for 500,000 houses in Wales, is to be located in Port Talbot, South Wales.

It is hoped the plant will generate power with 50 to 80% fewer carbon dioxide emissions than coal or gas-fired plants.

To ensure the necessary level of carbon dioxide reduction, the Environment Agency has insisted that all wood used at the plant is from sustainable sources.

Other legally binding conditions include ensuring that plant operation does not impact local air quality and the environment.
