Biogas and biomethane tenders
Biogas and biomethane tenders come mostly from waste and water authorities and from municipalities that own them. They tender anaerobic digestion plants for food waste and sewage sludge, upgrading units that turn biogas into biomethane for the gas grid or for vehicles, combined heat and power engines, and long-term operation and maintenance. Agriculture programmes and development banks add feasibility studies and farm-scale digester schemes.
Works and equipment notices set performance requirements: feedstock volumes and composition, gas yield, methane slip limits, digestate quality and uptime guarantees. Operation contracts often run for many years and transfer performance risk to the operator. Feasibility studies ask for feedstock assessment, technology options, offtake routes and the financial case, including any support schemes for renewable gas.

Frequently asked
What is the difference between biogas and biomethane?
Biogas is the mixed gas from anaerobic digestion. Biomethane is biogas upgraded to almost pure methane, so it can be injected into the gas grid or used as vehicle fuel.
Who tenders biogas plants?
Mainly waste authorities, water utilities and municipalities, plus agricultural and development programmes for farm-scale digesters.
Why does methane leakage matter in these tenders?
Methane escaping from digesters and upgrading units undoes much of the climate benefit, so buyers increasingly set limits on methane slip and require monitoring.
