Public safety is at the foundation of all we do. The Thornton Substation Project will comply with federal, state and company safety standards. It's our mission to ensure your family, neighbors, and every one of our employees stay safe each day.

Before and during construction, Xcel Energy will take safety measures including:

  • Update local schools with information on the latest construction activities and reminders about staying safe around work areas.
  • Set up barriers and fencing around construction sites.
  • Maintain traffic control to allow for a safe work area while providing drivers, cyclists and people on foot with the safest possible routes around the construction area.
  • Coordinate with the Fire Department during construction.

After hours, equipment will be stored behind barriers and/or fencing.

Please respect the work areas, follow all directions on signs and obey traffic flaggers.

Once in service, the Thornton Substation will be remotely monitored 24 hours a day, 7 days a week to ensure safe operations and to notify Xcel Energy of substation equipment emergencies. Xcel Energy has also offered to provide first responder training to the Thornton Fire Department, and provide online first responder training as needed.

Around our electrical system, please follow these tips to stay safe:

Overhead Power Lines

Before working outside, please look up and around to assess your surroundings. Contact with overhead power lines may result in serious injury or even death. Please keep all tools, equipment and vehicles more than 10 feet away from overhead power lines.

Call 811 Before You Dig

Are you planning to build a fence, install a mailbox or plant a tree this growing season? Before you start any outdoor digging project, no matter how large or small, “Know What’s Below.” Call or click Colorado 811 to locate and mark buried utility lines.

Hitting an underground utility line while digging can cause serious injuries, disrupt service to entire neighborhoods and potentially result in fines and repair costs.

One easy call to 811 starts the process. Visit to find out more.

Stay Away from Downed Power Lines

If you come across a downed power line, leave the area and report it immediately by calling 800-895-1999 and 911. Never approach a downed power line. Always assume that power lines and electrical equipment are energized and extremely dangerous. Touching a live line or anything near it, such as a fence, puddle, car, can cause electrocution resulting in serious injury and even death.
