A brief power outage Tuesday affected an estimated 45,000 customers between Grants Pass and Del Norte County.

The lights went out about 9:10 a.m., according to Pacific Power spokeswoman Laura Hastings-Brooks. The cause was a relay issue at the Grants Pass substation, she said. Power was restored at about 9:26 a.m.

According to Hastings-Brooks, although Tuesday’s power outage occurred in the same substation as a power outage on Aug. 31 and an earlier outage on June 19, their causes were different.

The power outage on Aug. 31 was caused by smoke from a wildfire near Grants Pass. Pacific Power spokesman Tom Gaunt told the Triplicate the transmission line had turned itself off. Utility personnel inspected the line, determined there was no damage and when the smoke cleared, turned the system back on.

A forklift accident at the Grants Pass substation caused the blackout on June 19, Hastings-Brooks said.
