Tamil Nadu State
Critical minerals, policy, and the energy transition
The Energy Transition in Tamil Nadu, India
Tamil Nadu, industrial powerhouse on India’s south-eastern coast, hosts the nation’s largest renewable fleet. Installed capacity tops 38 GW, with about 11.3 GW wind and 7.3 GW solar already meeting roughly 30% of annual demand and climbing fast. Recent auctions added 3 GW of wind–solar hybrids, and the state has awarded a 1,000 MWh battery-storage tender to firm evening peaks and tame monsoon variability. Flagship assets include the 2,245 MW Kamuthi and 1,500 MW Tirunelveli solar clusters, plus the 400 MW Kadamparai pumped-storage plant with a planned 2.5 GW Sillahalla upgrade. Green-hydrogen pilots are advancing: NLC is installing a 4 MW electrolyser at the Neyveli lignite mines, and Ennore Port is finalising an ammonia bunkering study. Beneath its lateritic uplands and coastal plains, Tamil Nadu holds a diverse mineral slate. Sivaganga hosts one of India’s richest graphite belts, Salem carries magnesite and bauxite for battery and aluminium value chains, and heavy-mineral sands in the Gulf of Mannar yield ilmenite, rutile and zircon—key inputs for titanium alloys, solar glass and rare-earth magnets. By coupling gigawatt-scale renewables, large-volume storage and this strategic resource base, Tamil Nadu is consolidating its role as India’s flagship hub for low-carbon power, green hydrogen and advanced materials.

A state-by-state analysis of India’s critical minerals and energy transition policies
SFA explores the state-level frontlines of India’s strategy to secure its position in the global energy transition. As demand surges for critical minerals used in electric vehicles, grid storage, solar, and hydrogen technologies, India is intensifying efforts to diversify supply, localise processing, and reduce strategic dependencies. This analysis examines how mineral endowments, state-level industrial policy, and renewable energy deployment intersect across the Indian landscape. From lithium-bearing pegmatites in Karnataka and Jammu & Kashmir to rare-earth-rich coastal sands in Tamil Nadu and Odisha, this state-by-state review highlights the opportunities and constraints shaping India’s clean-energy future and its role in global mineral security.
