SES Engineering Services was appointed to design, install, and commission the full MEP package for the Margam Green Energy Plant—a UK-critical 40MW biomass power station located near Port Talbot, South Wales.
Constructed by a consortium between Interserve Construction and Danish process supplier Babcock & Wilcox Vølund (BWV), the £160m facility is capable of processing 250,000 tonnes of waste wood annually, including contaminated wood, without pre-treatment. It also has future capability to process solid municipal waste, converting it into fuel—supporting both the Welsh economy and the UK’s renewable energy targets.
Owned by Glennmont Partners, a specialist clean energy investment fund, the plant represents a major step forward in sustainable energy infrastructure.
Comprehensive MEP scope
SES delivered full mechanical, electrical, and plumbing services to support the plant’s complex operations and long-term performance.
3D model integration
MEP services were designed directly into a centrally held 3D model, ensuring seamless coordination with BWV’s process systems and the building’s structural elements.
Strategic renewable infrastructure
The plant contributes significantly to the UK’s clean energy goals and sets a precedent for future biomass and waste-to-energy projects.
Sister project success
Following the successful delivery of Margam, SES was also appointed to deliver the Teesside Energy Centre—demonstrating continuity and trust in high-performance energy infrastructure.
