Trident Park clears commissioning stage

Viridor’s new energy-from-waste plant in Cardiff is now fully operational having completed the construction and commissioning phases.

Trident Park plant is currently going through final testing and validating for its R1 status from the Environment Agency, meaning that it can be classified as an energy recovery facility as opposed to one for disposal. 

Viridor says the plant was awarded R1 based on the technical specification, and operational data now shows it to be operating 35% above the required threshold. This data is now awaiting ratification.

Dai Stephens, general manager at Trident Park, said the process from a construction project to an operational facility had gone smoothly.

“We are very pleased with operational performance, particularly the energy efficiency of the plant. Trident Park is exporting 30MW of base load electricity to the grid, enough energy to power around 50,000 households.”

Alan Cumming, capital projects and engineering director, said: “The project has been delivered with a world-class safety record, on time and on budget, which is a tremendous achievement. This is a state-of-the-art facility delivered with sophisticated engineering and smart technology.

“The project has provided employment, training and wider economic and community benefits, and will now provide an essential service and jobs for those working on the plant and supporting it during its 25-year life.”

The facility will be handling 350,000 tonnes of residual waste, or post-recycling waste, per year. 172,000 tonnes of that waste will be coming from five councils that make up the Prosiect Gwyrdd partnership: Caerphilly, Cardiff, Monmouthshire, Newport and Vale of Glamorgan. 

Contractor CNIM/Lagan handed over the £223m construction project in January, and reliability tests are underway in preparation for performance testing in April.

Construction began in May 2012 with up to 600 workers at the site. Working hours on the project totalled over 1.6 million and with one lost-time accident during the project.
