UPDATE (1:39 p.m.) -- By 1:39 p.m., PG&E's outage map showed that power had been restored to the area.
UPDATE (8:28 a.m.) -- A PG&E representative confirmed the outage is affecting an area east of Santa Margarita, south from Hwy 58 and east to Pozo.
Crews from the power company are investigating the cause of the outage. Because the area is at high risk for fires, PG&E will have to inspect the entire line for equipment issues before power can be restored.
"This additional safety step could extend the length of the outage, but it is an important step to keep PG&E's customers and communities safe," Mark Mesesan, a PG&E representative, told KSBY in a statement.
A power outage reported Thursday morning has left 223 PG&E customers without electricity.
The outage affected homes in and around Santa Margarita, in northern San Luis Obispo county.
Power is estimated to be restored around 1:30 p.m.
PG&E is investigating the cause of the outage.
This outage in North San Luis Obispo County is the fifth PG&E power outage to affect the area since Sept. 7. The largest outage, recorded Sept. 12, affected over 3,000 customers in Atascadero.
