Mumbai, February 6, 2025: Tata Power has successfully restored Unit 5 (500 MW) at its Trombay Thermal Power Station in record time ensuring power supply to the grid after a fire in the cable vault on September 23, 2024. The restoration was done within record time of four months from order placement.
The fire had temporarily disrupted operations, but Tata Power’s Trombay team, in coordination with fire safety authorities, quickly contained the incident, assessed the damage, and executed a rapid restoration plan, ensuring minimal disruption to power supply.
Since 1956, Trombay Plant has been the cornerstone of Mumbai’s power infrastructure, marking a pivotal milestone with the commissioning of the city’s first thermal power station (62.5 MW). Over the following decades (1960–1997), the facility strategically expanded with the addition of eight more units, reinforcing Mumbai’s energy security and has proved extremely useful in the past during power related exigencies.
The Unit remains India’s first 500 MW multi-fuel generating unit—an engineering feat that necessitated the construction of a then-record 150m high chimney.
Today, Trombay remains a critical component of Mumbai’s power ecosystem, boasting a total installed capacity of 930 MW and ensuring reliable power supply to a diverse consumer base, spanning bulk and retail segments.
In addition to Unit 5, the other units at Trombay, along with company's three legacy hydroelectric power plants ( total 447 MW installed capacity) in the region, collectively contribute to the stability and sustainability of Mumbai's power supply. These hydro plants play a vital role in balancing peak demand and supporting renewable energy integration, further strengthening Tata Power's diversified energy portfolio
Tata Power is committed to continuously improving integrating advanced technologies to deliver a reliable and uninterrupted power supply to consumers. With Unit 5 now fully operational, the company remains focused on enhancing system reliability to meet the growing energy needs ahead of impending summer season.
