Thousands of Nevada County Residents were left re-setting their clocks and wondering what happened to the power last night. PG and E spokesperson Brandi Ehlers says they have traced the problem to a power substation in Grass Valley.*
Ehlers says a momentary outage by PG and E description can be anything up to 15 minutes.
Power came back on at 11pm but PG and E trouble shooters are still looking for what caused the momentary outage.
