Biogas
Organic matter breakdown, such as food waste, is turned into biomethane gas via a process called anaerobic digestion. Biomethane is a green gas that can provide heat and electricity.
Reliable Green Power supply for your business
At ENGIE UK, every green power contract is backed by Renewable Energy Guarantees of Origin (REGO) certificates, giving you complete transparency and assurance that your electricity is sourced exclusively from solar, onshore wind, and offshore wind projects.

Renewable technology
Where does our renewable power come from?
Biomass
Locally sourced waste wood and straw is burned in plants to generate power, supporting the circular economy and reducing transport emissions.
Energy from Waste (EfW)
Non-recyclable landfill waste is converted into reliable baseload renewable power.
Combined Heat and Power (CHP)
Electricity and thermal energy is efficiently generated using biomethane as a net-zero carbon power source.
Hydro
This is power generated from the flow of water, offering a reliable but intermittent energy source dependent on local water availability.
