EL DORADO HILLS (CBS13) – The latest on PG&E’s massive Public Safety Power Shutoff:

5:15 p.m. 

PG&E spokesperson Brandi Merlo confirmed the second phase of the Public Safety Power Shutoff began around 3 p.m. Wednesday.

The second phase of shutoffs will impact parts of San Joaquin, Stanislaus and Tuolumne Counties.

12:55 p.m.

PG&E says they’re delaying the second phase of their Public Safety Power Shutoff by several hours.

The second wave of power outages, this time affecting about 234,000 customers, was supposed to start around noon on Wednesday. Due to changes in the weather forecast, PG&E has pushed the power outage back a few hours.

Further, about 21,000 customers in Calaveras County and 800 in Mendocino County who were not part of the first phase will see their power cut during the second phase.

Earlier Wednesday morning, PG&E shut off power to 513,000 customers across Northern California. PG&E is telling residents that, if their county was part of the first phase of shutoffs but they still have power, then the Public Safety Power Shutoff will not affect them.

In total, nearly 800,000 PG&E customers could eventually see their power turned off.

7:07 a.m.

PG&E has started the first part of its Public Safety Power Shutoff.

Just after midnight, about 513,000 customers started to have their power cut.

PG&E says they’re also considering a third phase of power shutoffs that could affect about 42,000 in the utility company’s southernmost service area. Exactly when and which locations could see outages in this phase is still being determined.

In total, if the third phase is implemented, about 789,000 PG&E customers could have their power cut.

Hot, dry and windy weather is prompting the shutoff over wildfire concerns.

PG&E says forecasts show the concerning weather is expected to last through midday Thursday.
