SOUTH JORDAN — A circuit breaker issue at a Rocky Mountain Power substation led to a widespread power outage throughout the Salt Lake Valley Monday afternoon, officials said.
The outages were reported throughout the Salt Lake Valley, but most centered around South Jordan, West Jordan and Herriman shortly after 12:15 p.m.
In all, more than 57,000 customers lost power for nearly two hours until the issue was fixed before 2 p.m., Rocky Mountain Power spokesman Spencer Hall said in a statement.
Hall said a circuit breaker that "did not operate correctly" at Rocky Mountain Power's Oquirrh substation, located at 6000 West Old Bingham Highway, caused the outage. He added that led to problems at seven substations in the southwest part of the valley.
The cause of the malfunction remained under investigation late Monday afternoon, but Hall said there was no evidence of sabotage or tampering.
The power outage not only affected homeowners in the area, but also disrupted TRAX trains at the southwestern end of the red line route. A bus bridge was set up between the Jordan Valley and Daybreak stops because the trains, which run on overhead electric lines, didn't have any power in the area, a spokesperson for the Utah Transit Authority said.
The trains were back up in running between those stops shortly before 2 p.m.
The outage also affected multiple traffic signals across the valley and impacted "a number of schools" in the Jordan School District, according to district officials. However, classes were not affected by the outage.
