Tata Power said on Friday that fire broke out at a 250-MW unit of its thermal plant at Trombay. It also said that the reasons for "the event" as well as the damages would be ascertained in "due course".
Power generation from rest of the units remain unaffected by the incident. The project has an operational capacity of 1,580 MW.
The company said its Trombay thermal power plant had a localised incident of fire late on Thursday night.
"At 11.11 pm, a loud thud notice was observed in Low Pressure Turbine accompanied by fire on the turbine and generator deck of the 250 MW Unit 8 at Trombay," Tata Power said in a statement.
"The plant was safely shutdown including safe purging of hydrogen from the generator and safe shutdown of boiler, as the unit was running with about 185 MW capacity," the statement said.
Alternate supply is being maintained to meet the electricity demands of Mumbai consumers.
"No casualty has occurred nor is any human involved in the event associated with the key plant and equipment," it added.
In November, the company's 4,000-MW Mundra ultra mega power project in Gujarat had witnessed a fire incident.
Tata Power has generation capacity of more than 8,500 MW.
As of 3:16 p.m., shares in Tata Power were trading at Rs 80.90 apiece on the BSE, down 0.31 per cent from the previous close. (Track Stock)
