UPDATE: (6:13 a.m.) - PG&E was able to restore power to the impacted customers by about 8:20 p.m. Wednesday night, a PG&E spokesperson confirmed.
The outage was caused by equipment issues, and it was not a Public Safety Power Shutoff event.
UPDATE (1:18 p.m.) - Officials say Wednesday's power outage came when crews were working on a planned outage in Rocky Canyon, east of Atascadero. An equipment issue triggered the larger unplanned outage.
The areas affected by the outage include Atascadero, north to Creston and the area east of Santa Margarita Lake.
A PG&E spokesperson said that there is no estimate for when power will be restored.
Because outage area affects high fire threat areas, PG&E is using a helicopter to patrol the area.
The additional safety step could extend the power outage, but PG&E says that it is important to ensure community safety and reduce wildfire risk.
The power outage is not related to the Los Osos power outage that occured on Wednesday morning.
A power outage in north San Luis Obispo County has left 3,115 PG&E customers without power.
The outage was reported at about 11:25 a.m.
PG&E's outage map showed the outage affected Atascadero east of Hwy 101 down to areas near Santa Margarita Lake. Customers on both sides of Highway 58 were affected.
Power is expected be restored by 2:45 p.m.
We have reached out to PG&E to determine the outage's cause.
PG&E reported another power outage the same day in Los Osos. A PG&E spokesperson said the Los Osos outage was caused by equipment failure.
