Opening of the 6th season of the CHÊNE Fund: a last opportunity before 2026
ACTEE announces the opening of the 6th season of the CHÊNE Fund, a program that has become essential for local authorities wishing to prepare their energy renovation projects. This new season represents the last opportunity to apply for funding before the 2026 municipal elections and before the closure of the ACTEE+ program, scheduled for September 30, 2026.
📦A new budget for a final season before the municipal elections
The opening of this 6th season of the CHÊNE Fund comes at a particularly strategic time for local authorities. Thanks to the rigorous monitoring of the first five seasons, financial resources have been reallocated to allow for this final round of applications.
This is therefore a unique opportunity for local authorities to finalize, strengthen or relaunch their energy renovation initiatives before the 2026 municipal elections.
This new call for proposals will also give a second chance to projects submitted under CHÊNE 5 that were not selected due to insufficient funding. These applications can be resubmitted while retaining their original eligibility dates, thus providing welcome continuity for project leaders already committed to the process.
🌍 A season open to all communities
Season 6 is open to all communities, regardless of:
- Their size
- Their level of progress
- Their territorial organization (municipality, inter-municipal body, union, department…)
All lots are open:
- Lot 1: Flow savers
- Lot 2: Energy monitoring tools
- Lot 3: Energy studies
- Lot 4: Project management
- Lot 5: Project management assistance
Note:
- The specifications remain identical to those of season 5.
- Only the schedule and the priorities are changing.
- Local authorities can apply individually or as a group, which is strongly recommended for small municipalities.

🚀 Why apply now?
Beyond the dates, the main issue is that this is indeed the last opportunity to benefit from the CHÊNE Fund before 2026.
For local authorities, this season represents a real leverage effect: it makes it possible to finance all the studies, diagnoses and tools essential to structuring a solid energy renovation project.
By anticipating these steps, communities maximize their chances of unlocking funding for the works themselves in the years to come.
Furthermore, continuity with the CHÊNE 5 specifications facilitates the reactivation of projects already underway. Project leaders can thus build upon existing work without starting from scratch.
