Tata Power has successfully restored Unit 5 (500 MW) at its Trombay Thermal Power Station, ensuring a steady power supply to Mumbai after a fire disrupted operations in September 2024. The restoration, completed in a record four months, reinforces Tata Power’s commitment to providing reliable electricity to the financial capital of India.
A fire in the cable vault on September 23, 2024, had temporarily halted operations at Trombay Unit 5. However, Tata Power’s dedicated team, working in coordination with fire safety authorities, quickly contained the incident, assessed the damage, and executed an efficient restoration plan.
The power plant, which has been a key pillar of Mumbai’s electricity infrastructure since 1956, remains vital for the city’s energy security, especially ahead of the upcoming summer season when electricity demand peaks.
Trombay Thermal Power Station has played a crucial role in Mumbai’s energy landscape for decades. It was home to the city’s first thermal power station (62.5 MW) in 1956 and has since expanded with eight more units between 1960 and 1997.
Unit 5 is India’s first 500 MW multi-fuel generating unit, featuring an engineering marvel—a 150-meter-high chimney, then a record in India. Today, Trombay has a total installed capacity of 930 MW, making it one of Mumbai’s most critical power supply sources.
Beyond Trombay, Tata Power operates three hydroelectric power plants in the region with a total capacity of 447 MW. These hydro plants play a crucial role in balancing peak demand and supporting renewable energy integration, further solidifying Tata Power’s diversified energy portfolio.
With Unit 5 now fully operational, Tata Power is focused on integrating advanced technologies to ensure uninterrupted power supply to consumers. The company remains committed to strengthening system reliability as Mumbai prepares for the summer demand surge.
As one of India’s leading integrated power companies, Tata Power operates a diverse 15.6 GW generation portfolio, with 6.7 GW from clean energy sources, accounting for 43% of its total capacity. The company is actively working toward achieving carbon neutrality before 2045 while serving over 12.5 million customers nationwide.
This swift restoration of Trombay Unit 5 reaffirms Tata Power’s ability to manage energy crises efficiently and reinforces its position as a trusted power provider for Mumbai.
