Exploring Technologies for the Clean Energy Transition of Tamil Nadu

The paper evaluates various renewable and clean energy technologies for Tamil Nadu, analyzing their Technology Readiness Levels (TRLs), current installation capacities, and barriers to adoption. It identifies significant potential for wind repowering, offshore wind development, solar PV expansion, and the deployment of battery energy storage systems (BESS). Additionally, it examines the role of green hydrogen and bioenergy in the state's energy mix, emphasizing the need for supportive policies and infrastructure to facilitate the transition.

• Tamil Nadu has a significant immediate market potential for wind repowering of 834 megawatts (MW), with an additional 3,979 MW potential by 2027, as turbines from the 1990s reach the end of their lifecycles.
• Offshore wind is identified as a high-potential sector with high-TRL technologies, supported by India's first upcoming tender for a 4 gigawatt (GW) project off the coast of Tamil Nadu, though port infrastructure and supply chains still require development.
• Solar PV market potential is high, with capacity addition plans of 20 GW; while monocrystalline shares are increasing, higher-efficiency technologies remain costly and require policy promotion.
• Battery Energy Storage Systems (BESS) are seeing expanding market potential due to variable renewable energy, with a planned capacity of approximately 10 gigawatt-hour (GWh) in Tamil Nadu over 10 years.
• Green hydrogen production via alkaline and polymer electrolyte membrane electrolyzers has a TRL of 7–9, offering immediate benefits for replacing fossil-fuel-based hydrogen in refineries and fertilizers; Tamil Nadu has been selected for the establishment of green hydrogen valleys.
• Bioenergy technologies with high TRLs are available, and cogeneration power plants with an installed capacity of 90 MW are currently under way in Tamil Nadu.
