Construction of Anaerobic Digestion Installations

The reference figures mention aid that can be calculated as a flat rate per unit of annual production capacity, with a benchmark of €45/MWh (gross calorific value) for certain installations and a recorded maximum of €700,000. These values are not a funding promise: the scale, cap, type of energy use and applicable criteria must be checked in ADEME’s 2026 conditions before drawing up the financing plan.

An anaerobic digestion (biogas) project must secure the supply of feedstock, the installation’s performance, energy outlets and economic viability. ADEME can support the construction of anaerobic digestion installations, with aid calculated according to production characteristics and the scheme’s technical rules.

Who can apply

The scheme targets leaders of professional anaerobic digestion projects, notably companies, local authorities or agricultural and local organisations depending on the arrangement. Eligibility depends on the structure, the installation, the feedstock, how the biogas is used and compliance with technical and environmental conditions. The applicant must demonstrate the project’s viability and production outlets.

Eligibility conditions

The project must meet ADEME’s current conditions and reflect sobriety, appropriate sizing and energy use. The review may examine feedstock, performance, environmental impacts, digestate management, risk control and the project’s economics. The application must be submitted before any irreversible commitment, and the financing conditions confirmed with the regional office.

What the scheme covers

Investment in building anaerobic digestion installations eligible for the scheme, depending on production capacity and energy use. The application must describe the process, annual capacity, material balance, expected output, biogas treatment and use, digestate management and outlets. Preparatory works or ancillary equipment should only be included if accepted by the official rules.

Amount and funding terms

The amount is mainly calculated as a flat rate linked to annual production capacity, given as a benchmark of €45/MWh (gross calorific value) for certain projects. The €700,000 cap is a reference figure to be checked against the current scale, the type of installation and combination rules. The amount actually granted depends on the accepted production, eligible costs, the review and available funds; do not calculate final aid on the indicative rate alone.

How to apply

1. Define the feedstock, capacity and planned energy use. 2. Carry out the necessary technical, economic and environmental studies. 3. Check ADEME’s 2026 scale and conditions, notably the flat rate per MWh and applicable caps. 4. Contact the regional office before finalising the arrangement. 5. Submit a complete application with quotes, timetable, financing plan and performance data before starting work.
