Tata Power introduces new 400 KV transmission corridor for Mumbai

30 Mar 2023 CW Team

This new 400 KV transmission link will help fulfill the city's expanding electricity demand and will eventually boost electricity distribution to 15,000 MW.

If approved, this project might take four to five years to complete and cost roughly Rs 10 billion. The transmission line will be shaped like a ring with two hemispheres of 30 km each. When one hemisphere fails, the other acts as a failsafe.

Presently, 110 KV and 220 KV lines supply Mumbai's 3,500 Megawatt demand.

According to Tata Power, there will be no power shortages in Mumbai this summer, and load growth would be lower than national load growth.

Tata Power is responsible for around 70% of Mumbai's electricity transmission. Mumbai experienced a power outage that lasted up to 12 hours in certain locations on October 12, 2020. There were two further outages after that, both of lesser severity. Mumbai's peak power consumption is expected to hit 4,000 MW this summer, up from 3,300 MW in recent days as temperatures climb. Over the previous five years, the company has invested Rs 23 billion in upgrading its transmission infrastructure, including the replacement of over 90% of obsolete systems. The corporation plans to invest an extra Rs 7 billion in the coming fiscal year to improve its transmission capacity.
