A major milestone in the transformation of the former Aberthaw Power Station site has been reached with the demolition of the station's chimney stack.
Standing at approximately 650 feet tall, the Aberthaw stack was among the tallest structures in Wales and remained a prominent feature of the South Wales skyline for more than five decades. Constructed during the development of the power station in the late 1960s and early 1970s, the structure encased three flues and became closely associated with Aberthaw's historic role in electricity generation and industrial development across the region.
Visible from communities across South Wales and the Bristol Channel, the structure served as a well-known landmark and a lasting reminder of the site's contribution to the Welsh energy sector.
The controlled demolition was delivered safely by CCR Energy Ltd's demolition contractor, Erith Contractors Ltd, supported by specialist team, PDC Explosives Engineering, and carried out in line with strict safety and environmental controls. The operation forms part of the wider demolition and site-enabling programme currently underway at Aberthaw.
The removal of the stack will help unlock the next phase of redevelopment across the site, which is being prepared to support a range of future opportunities linked to clean energy, advanced manufacturing, industrial innovation and environmental resilience – in an area of strategic coastal importance.
The redevelopment programme continues to follow a phased and evidence-led approach, ensuring flexibility to respond to future investment opportunities, market demand and emerging technologies.
Paul Matthews, Chair of CCR Energy Board, said:
“The Aberthaw stack has been a defining feature of the South Wales skyline for generations and its demolition marks a significant moment in the site's ongoing transformation. While this represents the end of an important chapter in Aberthaw's history, it also reflects the progress being made to prepare the site for future investment and new opportunities. Aberthaw will play an important role in supporting sustainable industry, innovation and long-term economic growth for the region.”
Andy Dyson, Operations Director, Erith Contractors Ltd, said:
“The demolition of a structure as prominent and technically significant as the Aberthaw stack required meticulous planning, extensive engineering expertise and a safety-first approach throughout. We are proud to have delivered the operation safely and successfully as part of the wider transformation of the Aberthaw site.”
Works at Aberthaw will now continue with the next phases of demolition, remediation and site preparation, alongside ongoing masterplanning, infrastructure assessments and engagement with potential partners across the energy, industrial and innovation sectors.
