A massive fire broke out at NTPC's North Karanpura superthermal power plant in Jharkhand's Chatra district on Friday, officials said.
The fire was first spotted around 2 pm, they said.
"The fire broke out at the BHEL material yard of unit 3 in the power plant. So far no casualty has been reported," a senior BHEL official told PTI.
Efforts are underway to douse the blaze, he said.
The installation is a 660X3 mw coal-based power plant.
NTPC is the country's largest power generation company.
