All equipments in power plants are insured and cost of damaged equipment is claimed from insurance. In this case since there was no damage no claim needs to be put up,'' Tata Power said in an email response to query.
The company said the snag in unit occurred in auxiliary system connected with the furnace which eventually caused the furance to trip. The furnace which is operational for over three decades has been procured from Bharat Heavy Electricals Ltd under technical know how from Combustion Engineering, USA.
"TPC has proactive maintenance schedule for all equipments under preventive maintenance schedule. The same is strictly adhered too in coordination with system operator,'' the company said.
Maharashtra government has ordered an inquiry into the massive power outages faced in several parts of south and central Mumbai. Inquiry will be conducted by the state energy secretary within a week to fix responsibility and suggest short and long term measures to avoid such incidents in future.
Chief Minister Prithviraj Chavan informed that the decision to hold an in-depth probe was taken at the state cabinet meeting. "The state Cabinet has taken a serious cognisance of the power failure in Mumbai yesterday," Chavan tweeted on Wednesday.
Tata Power's Trombay plant has a generation capacity of 1,580 Mw. However, about 700 Mw of its capacity was not immediately available partly because of repairs and the request from BrihanMumbai Electric Supply & Transport (BEST) not to supply from unit 6 which runs on oil and gas.
