The blaze was contained by firefighters after two hours of battling the blaze.
Mohammad Hafezi, the power plant’s health and safety manager, told IRNA the cause of the fire was under investigation.
The two incidents in Iran’s oil-rich Khuzestan come after a fire and explosion at a centrifuge production plant above Iran’s underground Natanz nuclear enrichment facility early Thursday.
Officials said the cause of the fire at Natanz is known to officials, but won’t be immediately released for “security reasons.”
On Tuesday, an explosion from a gas leak in a medical clinic in northern Tehran killed 19 people.
