I've turned the alarms system off, it was producing too much noise.

We are recovering front end models.

Alarms are back on (currently no active alarms). I had to restart the locklossalert.service, it had gotten stuck.

BPA Dispatcher on duty said they had a breaker at the Benton substation open & reclose. At that time, they did not have a known cause for the breaker operation.  Hanford fire called to report a fire off Route 4 by Energy Northwest near the 115KV BPA power lines. After discussions with the BPA dispatcher the bump on the line or breaker operation, may have been caused by a fault on the BPA 115KV line causing the fire. BPA was dispatching a line crew to investigate.
