Tata Power, a vertically integrated power company and part of the Tata Group, India’s largest multinational business conglomerate, has announced a ₹15,000 crore (~US$ 1.5 billion) Mumbai grid upgradation and expansion plan to cater to the digital infrastructure being developed in the region.

In a press release, the company said that as demand from AI, cloud and digital platforms accelerate, the Company is expanding its role beyond power supply to provide a comprehensive suite of solutions, including powered land, transmission and grid connectivity, renewable energy, storage, cooling and utility infrastructure, enabling the development of hyperscalers and advanced data center facilities.

Tata Power says that it has a diversified opportunity pipeline of over 2.8 GW spanning renewable energy, transmission and distribution opportunities. It further explained that it had approximately 430 MW of upcoming load under its distribution network, 1,236 MW of transmission-linked opportunities, and 1,150 MW of green energy capacity under active engagement. It also said that it has 29 active workstreams across 18 leading global and domestic data center operators.

“To meet the rapidly growing power requirements of hyperscale data centres in the Mumbai Metropolitan Region (MMR), Tata Power is significantly enhancing its transmission infrastructure through the upgradation of its 110 kV and 220 kV network,” it said, adding. “In parallel, Tata Power is developing new receiving stations and advancing a 400 kV transmission ring network, creating a resilient, secure and future-ready grid capable of supporting the next wave of data center growth in the region.” This infrastructure enhancement forms part of Tata Power’s ₹15,000 crore Mumbai Grid Upgradation and Expansion Plan.

The Ministry of Power, based on CEA estimates, projects that AI-led data centers could add approximately 26.3 GW of electricity demand by FY2031-32. With the IEA highlighting the growing role of emerging economies such as India in driving data center and electricity demand, Tata Power aims to deliver the integrated energy infrastructure required to support the country’s digital future.
