Power, control and full MEP systems for the UK’s first dry anaerobic digestion plant, serving process equipment, control rooms and site infrastructure.

Scope.
The MET plug Flow Digester is the UK’s first dry anaerobic digestion facility supplying biomethane directly to the national grid. Carbon Synergy was appointed by Thöni GmbH to provide full power and control services for the process plant.
This included the delivery of stainless-steel product pipework, hydraulic and pneumatic delivery and control systems, and process heating and insulation services.
Following further discussions with Melton Energy Tech and Thöni GmbH the scope expanded to cover site-wide electrical system such as fire alarm systems, access control, lighting, and power for control rooms and offices.
Full mechanical HVAC systems were also installed for these spaces. Carbon Synergy was additionally tasked with delivering final power connections from the LV transformer, incorporating automatic emergency switching.
Challenges.
- Coordinating cross-discipline installations within tight plant commissioning timelines.
- Managing scope creep from a process-only package to include site-wide electrical and mechanical infrastructure.
- Delivering in a live environment where phased commissioning was essential.
Key Takeaways.
- Flexibility and depth of in-house capabilities allowed for seamless project scope expansion.
- Strong communication and coordination with both the client and equipment supplier ensured alignment from concept to commissioning.
- Solidified Carbon Synergy’s position as a partner capable of delivering high-integrity solutions in complex, first-of-its-kind facilities.
