The 650-foot chimney stack at the former Aberthaw Power Station was demolished on June 12, marking a landmark moment in the site’s transformation from coal-fired industry to a centre for green energy and innovation.
Standing for more than 50 years, the stack was one of the tallest structures in Wales and a familiar feature on the horizon for communities across South Wales and the Bristol Channel.
Paul Matthews, chair of the 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 today 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.”
The controlled demolition was carried out by CCR Energy Ltd’s demolition contractor Erith Contractors Ltd, with support from PDC Explosives Engineering.
It was delivered in line with strict safety and environmental standards.
The chimney, built in the late 1960s and early 1970s, housed three flues and was a central element of the old coal-fired plant, which ceased operations in 2020.
Its removal is a key step in the ongoing redevelopment of the site, which is part of a broader regional strategy to attract investment in clean energy, advanced manufacturing, and industrial innovation.
Andy Dyson, operations director at 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.”
The 650-foot (198-metre) stack was visible from miles around and had long served as a highly recognisable marker of the area’s industrial legacy.
With the stack now gone, focus turns to the next phases of the site’s redevelopment, including continued demolition, land remediation, and infrastructure assessments.
Masterplanning is underway, with engagement ongoing with partners across energy, industry, and innovation sectors.
Plans for the Aberthaw site centre on creating long-term opportunities for investment, sustainability, and regional growth.
The aim is to secure its role as a driver of economic progress for generations to come.
The redevelopment programme remains flexible and evidence-driven, designed to respond to shifting market demands and emerging technologies.
By clearing the site, CCR Energy hopes to unlock a range of future uses linked to clean energy and environmental resilience on this strategically important stretch of the South Wales coast.
The transition signals both the end of an era and the start of a new chapter, as Aberthaw moves from coal to a cleaner, more sustainable future built on innovation and investment.
The success of the demolition is seen as a critical moment in making that vision a reality.
