The operation concerns the construction of an anaerobic digestion unit carried out by CAP VERT BIOENERGIE EXPLOITATION 18 (CVBEE18), a subsidiary of the CVE group, on TRIFYL's renewable energy cluster located in the municipalities of Labessiere-Candeil and Montdragon (81). This methanisation unit will produce biogas which, once purified into biomethane, will be injected into the TEREGA transmission network, via a pipeline and an injection station shared with the methanisation unit operated by TRIFYL. The provisional period of execution of the operation runs from 01/12/2021 to 31/12/2025.
