Southern California Edison said most power to the 1,635 households affected by the outage should come back by 5 p.m. today.
Southern California Edison blamed the outage on an equipment failure. The owner of a nursery in North Long Beach said power cables fell onto his property.
The power outage spanned from Anaheim Street to Hill Street and from Long Beach Boulevard to Magnolia Avenue.
An underground power vault fire has left some businesses and homes near Downtown without power for nearly an hour late Saturday afternoon.
A representative from SCE said it is not clear when the power will be restored.
A driver crashed into a power pole near Heartwell Park Friday evening, prompting a power outage in the area and a street closure for a few hours.
The cause of the outage is still under investigation, Southern California Edison spokeswoman Susan Cox said.
According to SCE officials, a total of 2,763 customers were without power at one point.
PCH was briefly shut down in both directions between Redondo Avenue and the Traffic Circle while crews worked to repair the equipment.
The outage started just before 11 a.m. with “equipment problems,” according SoCal Edison spokeswoman Mary Ann Milbourn.
