The Smokehouse Creek fire, which started on Feb. 26, has burned over 1.2 million acres and destroyed hundreds of buildings and thousands of cattle in the Texas Panhandle area.  

"Based on currently available information, Xcel Energy acknowledges that its facilities appear to have been involved in an ignition of the Smokehouse Creek fire," Xcel wrote in a press release. 

Xcel said it has been cooperating with investigations about the wildfire and has launched its own review of the incident. However, the company denied claims "that it acted negligently in maintaining and operating its infrastructure."
