A fire erupted at an Oncor Electric Delivery substation located in North Fort Worth early on Thursday, resulting in a significant explosion that could be heard from miles away. Investigators have confirmed the fire began at approximately 11:30 PM and quickly spread across the facility. Eyewitness reports indicate that flames were towering above the building, and several loud booms could be heard throughout the area. Fire department officials, including Fire Station No. 22, responded swiftly, but the intensity of the fire hampered initial extinguishing efforts due to hazardous conditions presented by the ongoing electrical hazards. According to Batallion Chief Thomas W. Weller, no injuries were reported, but the blaze caused widespread power outages, affecting over 20,000 customers at the peak of the incident. The cause of the fire is currently under investigation, with preliminary assessments focusing on potential equipment failure as a leading cause. A video recorded by witnesses highlighted the scale of the explosion, emphasizing the urgent need for nearby residents to evacuate temporarily. Meanwhile, Oncor released a statement reassuring customers that they are working diligently to restore power and assess the damages sustained by the facility. They expect to provide updates throughout the day as repairs and investigations progress.
