"Our transmission system is a key inter-link between the generation and distribution of power as it plays a two-fold role by linking the city with Maharashtra state grid as well as the National Grid. We have already spend nearly Rs 1,000 crore on strengthening the network," Executive Director Operations S Padmanabhan said in a statement.
The peak load of Mumbai was around 3500 MW in 2012, as against the embedded generation capacity of 2300 MW.
"The remaining power requirement gap was bridged by importing power to the city through our transmission network", he said.
Padmanabhan said the company is also planning to expand its transmission business further in the city.
Recently, Tata Power commissioned additional transmission lines in Maharashtra between Kalwa and Salsette. This 220 kV line has already relieved the critical loading of the Kalwa- Salsette lines and has enhanced the transmission capacity for bringing power from outside to Mumbai city, the release said.
Further, the company has also started work on installation of 400 Kv station at Vikhroli and 400 Kv Transmission lines from Kharghar/Nagothane to Vikhroli.
