On the evening of Aug. 3, downtown Sparks—which is heavily residential—went dark at the very instant that the first note of music from an outdoor concert in the downtown was heard across the area. Residents who gathered on the sidewalks of the darkened neighborhood speculated on whether the concert caused the outage, particularly given the fact that it still had power and no one else did.

A statement from NV Energy said, “The cause of the power outage in Sparks on Saturday night was equipment failure in a vault.”
