One of India's biggest conglomerates. Tata Motors accounts for over half of India's corporate R&D spending, though most of that comes from its British subsidiary, Jaguar Land Rover (JLR). Building India's first commercial chip fabrication plant ("fab") in an $11bn partnership with Powerchip, a Taiwanese semiconductor manufacturer. The factory is in Dholera, a special investment region in Gujarat, and will produce workhorse semiconductors for use in vehicles, white goods and entry-level smartphones—not the cutting-edge chips made in Taiwan. The Indian government is providing 50% of project costs; state authorities are contributing another 20-25%.
Tata Power runs a joint venture with the state of Odisha to operate the state's electricity distribution companies (discoms). When the joint venture launched six years ago, all four state-run discoms were deep in debt and leaking 25-30% of their power. Since then, power losses have fallen by almost half while prices have been held flat. Odisha's discoms are now considered among the best-run in India. From its headquarters in Bhubaneswar, the state capital, staff monitor the network in real time. Tata Power has rolled out smart meters and nudged customers towards digital payments. Most customers still pay in cash; to reduce graft, bill collectors rotate their routes every six months.
Tata Consultancy Services (TCS) is the group's IT-outsourcing arm. In 2025 TCS was identified as the "means of access" in cyber-attacks on Marks & Spencer, the Co-op and JLR. TCS denied that its own systems or users were compromised.
In 2025 a cyber-attack on JLR, claimed by "Scattered Lapsus$ Hunters", brought its production lines in northern and central England to a halt. The stoppage was thought to have cost JLR £50m ($67m) a week and strangled suppliers. Britain's government underwrote a £1.5bn loan to the firm to help preserve its supply chain, which employs some 100,000 people.
