Cardiff EfW

Cardiff Timelapse

Trident Park Energy Recovery Facility in Cardiff is now only a few months away from completion.

Once fully operational the facility will be handling 350,000 tonnes of residual waste, or post-recycling waste, per year, generating 28MW of electricity - enough to power around 50,000 households.  172 tonnes of that waste will be coming from five Councils that make up the Prosiect Gwyrdd partnership: Cardiff, Newport, Monmouthshire, Vale of Glamorgan and Caerphilly. 

The facility is currently undergoing a process called commissioning.  As part of that process we will be testing the boilers and steam blowing the pipework.   Boiler testing is scheduled for 18 August and will last for approximately one week.  You may notice during this time an occasional plume from the chimney as the boilers are fired up.

Steam blowing is planned for September and is required to clean out the internals of the steam pipes following the construction process.  Steam blowing will produce a visible plume of steam and can be a noisy process consisting of a loud rumbling noise.  Commencement of this steam blowing is scheduled for:

Monday 22 September for 10 days.  This will involve a single blow each day (including the weekend) between 10am and 12pm lasting for approximately 15 minutes. 

Steam blowing is a standard and safe process that is part of the commissioning process only.
