Pacific Gas and Electric Company (PG&E) submitted their timeline of events on Monday after a U.S. District Court Judge ordered the utility company to explain its role in the Zogg Fire. The order came after CAL FIRE took possession of PG&E equipment as a part of its Zogg Fire investigation.

The following is PG&E's timeline of events on September 27, 2020 -- the day the Zogg Fire broke out.

Around 2:40 p.m., PG&E said that a Smart Meter for a home at Zogg Mine Rd and Jenny Bird Ln saw a drop in voltage and lost power.

At 2:41, there was a spike in the electrical current going through a power line serving the area. For an automatic shutoff to happen, a surge like this has to be a certain size and last for a certain length of time. In this case, the surge was strong enough but didn't last the 20 to 25 seconds needed to trigger an automatic shutdown.

At the same time, a circuit breaker at the substation serving Zogg Mine Rd experienced a surge. It did not last long enough to cause a shutdown.

At 2:42 p.m., another surge was detected, but once again, it did not last long enough to trigger a shutdown.

At this point, smoke that could have been from the Zogg Fire was seen three miles east of Zogg Mine Road on a Firewatch camera.

At 2:43, Three Smart Meters saw a drop in power on Zogg Mine Rd. One shut down.

A weather satellite detected a heat signature in the Igo-Ono area at this point.

Between 2:44 and 2:47, there was another surge in the power line. Once again, it did not last long enough to cause a shutdown.

At 3:00 p.m., PG&E said one of its employees saw the Zogg Fire from Knighton Road in Redding and reported it to their Distribution Control Center.

At 3:06 p.m., another power surge hit the power line. This surge did last long enough to cause an automatic shutdown.

The court order PG&E was responding to also asked it to "describe the extent of trimmed and untrimmed vegetation" near Zogg Mine road.

PG&E said that it was not aware of any trees that needed to be trimmed or removed in the area, but were not at the time of the Zogg Fire.
