Introduction
Setting a green benchmark in maritime infrastructure and sustainability, the V.O. Chidambaranar (VOC) Port in Thoothukudi, Tamil Nadu, became India's first major port to achieve certified Scope-2 Emission-Free status on 14 August 2026. The port also created history by becoming the first Indian major port to be awarded the prestigious ISO 50001:2018 Energy Management System certification.
Clean Energy Transition at VOC Port
The port accomplished this green operational transition through aggressive renewable energy deployment and energy efficiency overhauls during 2025–26:
- Renewable Energy Dominance: Met an astonishing 93.89% of its total electrical energy requirements through dedicated captive solar photovoltaic and wind energy installations.
- Green Tug & Shore Power: Operationalised 100% shore-to-ship electricity power supply at berths, eliminating auxiliary diesel engine emissions from berthed cargo vessels.
- Harbour Electrification: Transitioned container handling cranes, rubber-tyred gantry (RTG) cranes, and port utility vehicles to electric drives.
- Harit Nauka & Green Hydrogen Hub: VOC Port is emerging as a flagship green hydrogen and green ammonia bunkering hub under the Ministry of Ports, Shipping and Waterways' Maritime Amrit Kaal Vision 2047.
