(KSL News) -- The lights are back on for over a thousand Utah Power customers who spent much of the night in the dark in Salt Lake County.
Utah Power says a line connecting two substations blew at 90th South and 40th West just before 10:00 last night.
Residents in the area say they originally thought they heard some sort of explosions when the line went down.
Cindy Chavez, Witness: "Heard three booms and saw like, lightning, and we thought we saw lightning, but on a clear night we thought it was kind of strange."
Utah Power says there weren't any explosions, but surges from the 138,000 volt line may have sounded like a blast.
Fortunately, no one was injured.
