Producing biomethane continuously: why every shutdown matters<\/h2>

Monday, 8 a.m. Six Waga Energy technicians and engineers arrive at Veolia's landfill site in Chatuzange-le-Goubet, in southeastern France. Their mission: perform the annual maintenance of the WAGABOX\u00ae unit that upgrades landfill gas into biomethane injected into the gas grid.<\/p>\n

Designed to operate 24 hours a day, 7 days a week, the unit is remotely monitored and controlled from Waga Energy's headquarters in Eybens, near Grenoble. But like any industrial facility, it must be taken offline at regular intervals for inspection, maintenance, and upgrades. This is a sensitive operation because every hour of downtime matters: the less time the equipment is unavailable, the more biomethane it produces, the more value it generates for partners, and the more CO\u2082 emissions it helps avoid.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>\r\n\r\n

The WAGABOX\u00ae maintenance: planned like a critical mission<\/h2>

The maintenance operation was prepared several weeks in advance. Tasks were identified, parts ordered, teams mobilized, and logistics organized down to the smallest detail. The previous week, containers carrying tools, personal protective equipment, and the parts required for the work were delivered to the site, along with several pallets of consumables and spare parts. Once the WAGABOX\u00ae unit is shut down, the clock starts ticking.<\/p>\n

\"Maintenance operations are scheduled every 8,000 operating hours<\/em>,\" explains Matthieu Rouvi\u00e8re, one of Waga Energy's traveling maintenance team leaders. \"We overhaul compressors and other equipment in accordance with manufacturers' recommendations. Our work covers both preventive maintenance and corrective operations that can be planned during the annual shutdown. Depending on the type of maintenance, the number of interventions required can vary significantly.<\/em>\"<\/p>\n<\/div><\/div><\/div><\/div><\/div>\r\n\r\n

Revamping: how Waga Energy improves units already in operation<\/h2>

Beyond preventive maintenance, these planned shutdowns also provide an opportunity to upgrade units already in service. Innovations developed by Waga Energy's Research & Development and Process Engineering teams are progressively rolled out across the existing fleet.<\/p>\n

\"Innovations integrated into the latest generations of WAGABOX\u00ae units are installed on units already in operation whenever it makes sense to do so. That's what we call revamping<\/em>,\" continues Matthieu Rouvi\u00e8re.<\/p>\n

This approach reflects one of the key principles of Waga Energy's business model: the company does not simply design and install its units. It also operates, monitors, maintains, and continuously improves them throughout the duration of each contract. This comprehensive responsibility enables Waga Energy to leverage experience gained from every site, continuously improve fleet performance, and provide customers and partners with a high level of reliability.<\/p>\n

Maintenance shutdowns may also be used to conduct regulatory inspections, particularly on pressure equipment. These inspections are carried out by an independent organization in compliance with applicable regulations. In some cases, tanks must be emptied to allow for inspections and leak-tightness tests before the unit can be returned to service.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\r\n\r\n
