Coffey, working with Kanadevia Inova, is delivering Stream BioEnergy's flagship €80 million biomethane facility at Little Island, Co Cork, in a major boost to Ireland's renewable gas infrastructure.

Scheduled to come online in 2027, the plant will treat 90,000 tonnes of domestic and commercial food and garden waste each year and supply more than 80GWh of renewable biomethane to the Irish National Grid. It will be the country's largest biomethane facility for municipal food and garden waste, supporting the Government's 2030 goals under the National Biomethane Strategy.

The development is expected to reduce greenhouse gas emissions by roughly 40,000 tCO₂e per year. It will also produce sustainable biofertilisers by recycling nutrients from food waste, helping to promote more sustainable farming and lessen dependence on fossil fuels in difficult-to-decarbonise sectors such as heating and transport.

Coffey's civil, mechanical and electrical expertise is being combined under an EPC contract with Kanadevia Inova to deliver the integrated infrastructure required for large-scale biomethane production and grid injection. The project underscores the growing importance of renewable gas in Ireland's long-term decarbonisation plans.

Joe Lavan said: "As main contractor, we're proud to apply Coffey's engineering expertise and our growing strategic focus on the energy sector to a project of this scale. Delivering the Little Island facility aligns closely with our commitment to supporting Ireland's transition to cleaner, more resilient energy infrastructure. This development showcases how strong collaboration can drive real progress while creating long-term value for local communities and industry."

The Little Island scheme adds to Coffey's expanding energy portfolio, which includes fast‑track emergency generation facilities, sustainable biofuel projects and synchronous condenser installations across Ireland and the UK. By converting organic waste into renewable gas, the project advances the circular economy, strengthens energy security and lowers emissions.

Beyond environmental benefits, the investment is set to deliver significant economic value. A substantial share of the €80 million budget will support local civil, mechanical and electrical contractors. Construction is expected to create more than 100 jobs, with over 20 permanent roles once the facility is operational, and around €4 million in annual local expenditure thereafter.

As Ireland accelerates its shift to renewable energy and greater resilience, projects like Little Island will be central to achieving national climate objectives and building sustainable infrastructure. For Coffey, the development reflects an ongoing commitment to engineering excellence, innovation and collaboration across the energy sector.
