On Tuesday, May 21, 2024, the following information was communicated to a small group of Southern Power employees regarding action items from Winter Storm Heather:

Scrubber foaming issue at Plant Miller resulted in Unit 4 trip on 1/21. Foaming in the scrubber is believed to have resulted in a false level indication in the JBR. The level was higher than indicated which resulted in an increase in back pressure which tripped both ID Booster fans. The bypass damper stuck at 8% open and caused an overpressurizaiton of the ID fan ductwork and blew out all 4 ID Fan expansion joints. RCA to be conducted and shared with the system on lessons learned.

Scherer 3 “A” FD fan motor trip after fire system deployed, likely result of dry system bulb crack due to cold temperatures, 400 MW derate. And ~40 MWs peak capacity impact. Review and make recommendations if fire system design or winter checklists should be revised.

Brief Description

Walnut Grove - Inverter Overcurrent HW Fault, Control Fault

Full Description

Walnut Grove - We received three alarms: Inverter Overcurrent HW Fault, Control Fault: Controller Program, Inverter Fault Active. Site Control Inverter Status was Inverter Faulted. The Recloser was Closed, the Ground Switch was Tripped, the AC Disconnect was Closed, the AC Contactor was Tripped, and the DC contactor was Tripped. I placed the Site in Shutdown, Operating Mode was placed in Manual. I reset the Inverter Fault, then the Controller Fault. Inverter Status changed to PQ Ready. The Site was placed back into RUN with an Operating Mode of Solar Pluss Bess. The Inverter Status went to Running PQ. All alarms cleared. Consulted with Stan Houston regarding the issue. Based upon the alarms, status of the switches, and equipment it appears to have been a site issue, not an external issue.
