Fire at GWP Grayson Power Plant

More than two dozen firefighters battled a blaze inside a cooling tower at the Grayson Power Plant, officials said, containing a fire that sparked in record heat.

The tower has been isolated and the power grid should remain unaffected as temperatures neared the triple digits, city spokesman Ritch Wells said.

No injuries were reported.

Firefighters responded to the plant at 6:33 p.m. after witnesses reported heavy black smoke billowing from one of the cooling towers, Glendale fire Capt. Vince Rifino said.

Foam was sprayed onto the tower, and firefighters brought the blaze under control by 7:50 p.m., he added.

The cause of the fire is still under investigation, but utility officials said they suspect it was an electrical fire caused by a faulty fan inside the tower.

Investigators wouldn’t know for sure until the fire was completely knocked down and it was safe to go inside, Rifino said.
