Gardner City staff report engine failures during recent power-plant run; vibration and false fire-sensing cited
Summary
Staff told the Utility Advisory Commission that during a recent run both engines failed and false readings from vibration and a fire-sensing module triggered the CO2 suppression system; vendors are engaged to troubleshoot.
Staff told commissioners that a requested run of the power plant about a week earlier resulted in both engines failing: one unit tripped due to vibration and the plant received false readings from vibration monitoring and a fire-sensing module that triggered the CO2 fire‑suppression system. “And during the run, both engines failed,” the staff member said, and staff have engaged a vibration-analysis contractor and the fire-suppression company to investigate.
Staff said vendors will coordinate troubleshooting between the vibration system and the fire-suppression system to ensure accurate sensing and to clear spurious trips, and that operations have been resilient despite the recent problems. Commissioners asked for updates as diagnostics are completed.
