Centrica Energy, in collaboration with its Irish supply business Bord Gáis Energy, has signed a long-term offtake and route-to-market agreement with Stream BioEnergy for Ireland's largest biomethane facility processing municipal food and garden waste, currently under development near Cork. Under the agreement, Centrica Energy will offtake 100 per cent of the biomethane produced at the facility and manage the associated green certificates, ensuring the renewable gas reaches the market efficiently.

Centrica reported that when operational in 2027, the Little Island plant will process 90,000 tonnes per year of domestic and commercial food and garden waste to generate 80 GWh of unsubsidised biomethane annually for injection into the Irish gas grid. The project is backed by investors Goldman Sachs Asset Management and Pioneer Infrastructure Partners.

Cassim Mangerah, managing director of Centrica Energy, said the firm is proud to partner with Stream BioEnergy on a project that turns waste into clean, renewable energy, and that its role in managing the full offtake and certificates ensures biomethane can be brought to market efficiently, delivering real value to Irish consumers and contributing to a lower-carbon future.

Kevin Fitzduff, co-founder of Stream BioEnergy, said the company is proud to have started construction on one of Ireland's largest biomethane facilities, a key part of Ireland's decarbonisation journey, and that working with Centrica Energy ensures the output is professionally managed and brought to market efficiently, helping to establish biomethane as a reliable part of the country's energy mix.

The deal arrives at a critical juncture for Ireland's biomethane sector. The European Commission has blocked a key support mechanism within Ireland's Renewable Heat Obligation scheme, prompting industry calls for focused government action to sustain investment momentum across the nascent sector.
