More than 150 insurance companies and two survivors of the catastrophic Marshall fire are suing Xcel Energy for the utility company’s role in Colorado’s costliest and most destructive fire.

The lawsuits come a month after the Boulder County District Attorney’s Office and sheriff’s office announced the findings of their 18-month probe into the cause of the 2021 fire. The report found the fire had two ignition points, including an Xcel Energy power line that arced after it disconnected amid high winds and sent hot particles into dry grass.
