Streetlights along public streets in the city are owned and maintained by either Xcel Energy, United Power, or the city of Thornton. To streamline the repair of a streetlight, it is recommended that streetlight malfunctions, outages, or downed streetlights be reported directly to the appropriate organization.

A few tips to determine which company to contact to report the outage:

• A yellow and black tag is owned by either Xcel Energy or United Power. (Write down the tag number from the street light pole to expedite the report).
• United Power streetlights are generally located in the northeast area of the city, east of Holly Street and north of 104th Avenue.
• A blue and white tag is owned and maintained by the city and the city should be contacted for repair.
