Uskmouth conversion on track, pellet plant begins commissioning

SIMEC Atlantis Energy Ltd. has announced the biomass conversion of the previously coal-fired Uskmouth power station in Newport, South Wales, U.K., is on track to begin operations by 2021. Once complete, the 220 MW facility will be fueled with waste pellets.

Atlantis said front end engineering design (FEED) tests have been successfully completed and a stable flame has been achieved in medium-scale testing, proving the stable combustion of 100 percent waste derived fuel pellets. The company said these results correlate to the computational fluid dynamics model and confirm a stable self-sustaining flame with combustion performance within expected parameters.

In an updated released in mid-July, Atlantis said a contract tender has been issued for the design, supply, installation and commissioning of the full combustion system, including large-scale combustion testing. The contract for the combustion system is scheduled to be awarded during the second half of this year. The company also noted that environmental planning and permitting for the plant is progressing. A full contract tender for the remaining conversion work is expected to be issued during the first quarter of 2020.

The company said N+P Group started commissioning a new pellet facility in Teesport, England in June. That facility will supply fuel to Uskmouth power station. According to Atlantis, three other U.K. facilities are planned to supply fuel to the project. The waste pellets used to fuel the plant will contain a high proportion of plastic waste. Once fully operational, the Uskmouth power station is expected to consume approximately 900,000 metric tons of waste-derived pellets annually. An industrial-scale fuel production run and milling test is scheduled to take place during the second half of this year.
