Equipment failure caused a major power outage in Seattle on Wednesday.

The city's electric utility, Seattle City Light, confirmed a "large" outage in a tweet around 11:40 a.m. local time. It later said power was mostly restored at about 12:30 p.m., but that some "small outages" remained.

The disruption was attributed to an equipment failure at a substation on Massachusetts Street.

Twitter users shared pictures of dark buildings and cars lined up at intersections where traffic lights had gone out. The Seattle Police Department said in a tweet to handle intersections without lights as a four-way stop.

Video from the city showed slow movement of cars and pedestrians at intersections during the outage.
