STL Energy, from CHP to biomethane

GCS have supported STL Energy to convert their plant from CHP only to a combined CHP and Biomethane plant.

The plant now produces around 40GWh of green gas per year, recovers CO2 as a value stream and feeds electricity into the gas grid at 70Bar. Heat generated is also used for intensive farming operations. The gas to grid expansion first injected biomethane in in 2016.

GCS supported:

- Technical integration strategy to maximize plant performance and operability while utilizing existing hardware
- Technical specification of key vendor work-packages with support for vendor selection and management
- Site layout and systems integration design
- Deployment site management including construction oversight and problem-solving
- Gas to grid connection management including GNO liaison, grid entry agreements, injection system specifications, and commissioning oversight

After 9 years of successful operation. GCS are supporting STL energy with a further expansion of this plant.
