Tata Power has announced a massive Rs 15,000 crore investment plan to upgrade its distribution network in Mumbai by 2029, aiming to meet the city's surging demand for green energy. Dr Nilesh Kane, Chief of Transmission and Mumbai Distribution, revealed the details during an exclusive interview on the sidelines of a press conference in Mumbai.
Key Highlights of the Upgrade Plan
The comprehensive modernization plan focuses on enhancing transmission capabilities and grid flexibility. Dr Kane emphasized that the company is reducing its dependence on coal by strengthening renewable power availability. As part of the initiative, Tata Power will double its Battery Energy Storage Systems (BESS) capacity from 100 MW to 200 MW by the fiscal year 2027, ensuring round-the-clock green power supply.
Critical Infrastructure Developments
A major component of the plan is the construction of a 400 kV bulk power ring network across Mumbai, connecting key nodes such as Vikhroli, Dharavi, Mahalaxmi, Sewri, and Trombay. This robust ring network will be supported by the commissioning of 18 new sub-stations by 2031. Dr Kane described these upgrades as a milestone for Mumbai, promising the best power reliability.
Renewable Energy Expansion
To power the expanding grid cleanly, Tata Power has secured approvals for 250 MW of hydropower renewable energy and a 150 MW solar plant. The company is pacing toward an ambitious 70% clean energy target by 2031. This capital expenditure comes at a critical time, as Tata Power-Distribution expects its network's peak demand to reach 2,000 MW by FY31.
Current Operations and Future Demand
Tata Power currently serves as a foundational energy provider for Mumbai, maintaining a daily output efficiency of 1,877 MW, which meets 25% of the city's total electricity demand. However, Mumbai's overall daily peak demand touched 4,642 MW this year and is projected to surge by 40% to 6,500 MW by 2031, driven largely by data centers.
Smart Meter Deployment
As part of its customer-centric approach, Tata Power is accelerating its smart meter deployment. Dr Kane revealed that the company aims to install 8 lakh smart meters by next year, adding that every new customer is receiving a smart meter. This initiative ensures the region remains reliably and sustainably powered.
