India’s First Major Port Runs Fully on Renewable Energy, Earns IGBC Platinum

V.O. Chidambaranar Port Authority has achieved a major sustainability milestone by becoming India’s first major port to receive the IGBC Platinum rating while operating entirely on renewable energy. The recognition highlights the port’s transition towards low-carbon infrastructure and energy-efficient operations, positioning it as a national leader in green port development.

The Platinum certification was awarded by the Indian Green Building Council for multiple administrative and operational buildings that meet advanced standards in energy efficiency, water conservation, waste management, and indoor environmental quality. These facilities are designed to minimise environmental impact while supporting long-term operational resilience.

In addition to IGBC recognition, the port has also secured certifications under the Bureau of Energy Efficiency’s Shunya and Shunya Plus frameworks, reinforcing its status as a near net-zero energy campus. Power requirements are met through a combination of on-site solar installations and renewable energy procurement, enabling the port to run 100% on green power.

This achievement aligns with the Government of India’s broader maritime decarbonisation agenda under initiatives such as the Green Ports and Shipping Policy. VOC Port’s progress demonstrates how legacy port infrastructure can be successfully repurposed to support climate goals, reduce emissions, and set replicable sustainability benchmarks for other major ports across the country.

V.O. Chidambaranar Port's IGBC Platinum plus BEE Shunya and Shunya Plus certification plus 100 percent renewable operation combining on-site solar with renewable procurement reflects the multi-technology delivery architecture that credible port decarbonisation requires. Single-technology approaches typically underperform; integrated portfolios deliver more reliable outcomes.

The legacy-port-repurposing dimension is analytically important. Greenfield sustainable-port design is comparatively straightforward; retrofitting existing operational ports to net-zero-adjacent performance requires substantially harder operational-and-capital planning. VOC Port's demonstration establishes template applicable to other Indian major ports facing similar retrofit challenges.
