DALLAS, August 25, 2020 – As of today, Oncor has completed its investigation of last week’s 3-alarm industrial fire. All Oncor lines were fully intact, above ground and in normal operation at the time the fire started. Moreover, investigating authorities, including the Grand Prairie Fire Department, have ruled out Oncor power lines, equipment or facilities as the cause of the blaze.

“We appreciate the diligent and thorough investigation by the Grand Prairie Fire Department and are grateful for the quick response and hard work of all first responders who helped extinguish the fire,” said Connie Piloto, Director of Communications at Oncor. “Safety is at the core of everything we do, and our engineering, construction and operations teams worked directly with local and federal officials throughout the investigative process. We are fully confident in the stability of our equipment.”

While the intense size and heat of the fire did impact the immediate surrounding transmission towers and distribution facilities, power was fully restored for all impacted customers by late Wednesday night and construction efforts are underway to restore or replace damaged equipment. This work is similar to the restoration process following natural disasters such as tornadoes, which Oncor personnel and resources are well prepared for. No further outages or grid impacts are expected.

Oncor’s electrical infrastructure is designed to meet or exceed national safety codes and engineering standards. Transmission towers are specifically built to not only support the thousands of pounds of power line weight, but to also withstand hazardous weather conditions, high winds and extreme temperatures.
