Construction of Biomass/Wood Heat Production Installations
The 2026 aid is for local authorities, companies and associations in all regions. ADEME recommends prior contact with the regional office and expects a project consistent with the EnR’Choix approach: sobriety, energy efficiency, pooling and consideration of waste heat before choosing biomass. The amount depends on the project’s characteristics and the applicable scale, not on a single rate for all.
Replacing fossil heat with a biomass boiler can reduce emissions and stabilise part of energy costs, provided the installation is properly sized and the fuel supply secured. ADEME’s Heat Fund (Fonds Chaleur) supports biomass or wood heat projects that meet its technical requirements.

Who can apply
The ADEME page is for local authorities, companies and associations. The project must concern a biomass/wood heat production installation and meet the performance, fuel and sizing requirements. Precise criteria may vary by output, type of applicant and installation characteristics.
Eligibility conditions
ADEME asks applicants to follow the EnR’Choix approach: reduce needs, study pooling or connection to a low-carbon network, and look at available waste heat sources. Sizing must be based on real needs and a technical study. Efficiency, sustainable supply, emissions and monitoring criteria must be checked in the official 2026 conditions.
What the scheme covers
The aid concerns building biomass/wood heat production installations. The application must detail heating needs, output, operation, annual production, fuel supply, emissions and the necessary treatment equipment. Heat networks, pooled needs or industrial processes may involve specific conditions; use the scale suited to the project.
Amount and funding terms
Funding is reviewed under the Heat Fund’s 2026 eligibility and financing conditions. The amount depends notably on heat output, performance and the costs accepted as eligible. No generic cap is given here without checking the scale for the project category. Ask ADEME’s regional office for an estimate based on the study and planned sizing.
How to apply
1. Reduce needs through sobriety and efficiency measures. 2. Study options for pooling, heat networks and waste heat recovery. 3. Commission a feasibility study and define the fuel, output and production. 4. Contact ADEME’s regional office to validate the criteria. 5. Submit the technical documents, quotes, financing plan and timetable before starting work.
Timeline
