Teesside Gas Processing Plant

Our Teesside Gas Processing Plant (TGPP) at Seal Sands is at the heart of the Teesside integrated energy network, connecting hydrocarbon-based transition fuels with new energy provision, powering the UK today and into a sustainable future.

Highly flexible in its operation, it has one of the highest liquid extraction rate capabilities in Europe. The plant uses two trains to process gas from the Central and Southern North Seas.

Capable of meeting up to 10% of the UK’s gas demand, this highly efficient and flexible two-train operation boasts a combined capacity of 675 million cubic feet of gas per day. Run by a proficient operations team with an exceptional safety record, our award-winning facility boasts an availability track record of >99%.

TGPP

Process

Gas from the Central North Sea is brought onshore to TGPP via the 400 km-long CATS pipeline. Gas from the Southern North Sea arrives via the 110km Breagh pipeline. The Breagh unmanned offshore facilities are operated remotely from the TGPP control room.

Benefits

Independence

Our primary business is processing third-party gas, providing high-quality, flexible service to all users.


Advanced technology

Our advanced processing can be tuned to suit the economic environment, allowing for liquid extraction rates of 11-14% (measured on an energy basis) as required.


Simplicity and flexibility

We optimise our processing services for the dynamic needs of our customers. We provide gas processing services and a route to market for fractionated natural gas liquids via integrated transportation and sales arrangements, simplifying offtake arrangements for our customers.


Performance record

Multiple industry awards reflect a commitment to achieving best-in-class standards for performance and plant availability, while maintaining excellence in quality, health, safety and environmental management.


Strategic location

The North Tees region boasts a dynamic and active Energy Transition environment, allowing us to connect upstream users to multiple customers building new sustainable energy provision options within one the UK’s industrial heartlands.
