As part of the inquiry to ascertain the reasons behind the massive power outage on October 12, government agencies have questioned Tata Power’s inability to protect the island city, and partly the suburbs, from a blackout by kicking in the islanding system.
The state government-operated State Load Despatch Centre has issued a notice to the firm, seeking an explanation over the delay in upping the generation from its thermal and hydro power plants, which should have been done within three hours.
While a Tata Power spokesperson said the firm rapidly initiated restoration, the Maharashtra State Electricity Transmission Company Limited (MSETCL) claimed it happened several hours after it asked the firm to increase the power generation in Bhira, Khopoli and Unit 5 in Trombay by 500 MW. MSETCL chairman and managing director Dinesh Waghmare said it usually takes 10 minutes for hydro power plants to raise capacity but Tata Power took almost seven hours.
“The firm’s Unit 5, which it claims was operational, connected to the grid only at around midnight. We had been asking them since 10.30 am on Monday, but they kept delaying it.”
