The Major Port Authorities Act, 2021, has been described as a transformative reform for Indian ports. Analyse its provisions and their role in enabling green and digital port infrastructure.

The Act repealed the Major Port Trusts Act, 1963, converting eleven trust-run major ports, including V.O. Chidambaranar (VOC), into corporatised Port Authorities [2]. Its significance lies less in nomenclature than in the autonomy it created — the enabling condition for green and digital investment.

Decomposing the provisions

• Governance: a compact Board of Port Authority with independent members replaces the large, nominee-heavy trust body, shortening decision chains [2].
• Tariff autonomy: the Tariff Authority for Major Ports (TAMP) stands abolished; Boards now fix their own scale of rates on market principles [2].
• Land and asset powers: Boards may lease land for port and non-port use and form PPPs/joint ventures [2].
• Financial autonomy: powers to raise loans, invest surplus and deploy own funds without routine central approval [2].

Role in enabling green infrastructure

• Land-leasing and JV powers let ports host green fuel assets: VOC commissioned India's first port-based Green Hydrogen pilot (₹25 crore, 10 Nm³/hr) and sanctioned a 750 m³ Green Methanol bunkering facility (₹35.34 crore) [3].
• Own-fund investment in renewables underpinned VOC's 45% cut in carbon emissions and Scope-2 emission-free status, disclosed in its first Sustainability Report [1].
• Autonomy allowed VOC, Paradip and Deendayal to be recognised as Green Hydrogen Hubs under the National Green Hydrogen Mission [6].

Role in enabling digital infrastructure

• Retained revenues financed VOC's Digital Twin — the first among major ports — using IoT, LiDAR and drone imaging for predictive maintenance [4].
• Over ₹1,500 crore of green and digital projects were launched at a single port, a scale unattainable under trust-era approval cycles [5].

Reassembling, the Act works as an enabler, not a mandate: it supplies autonomy, while decarbonisation targets come from mission-mode policy. Ports with weaker traffic and revenues cannot self-finance similarly. Extending viability-gap support and replicating VOC's model across all major ports would align port reform with Maritime Amrit Kaal Vision 2047 and India's net-zero commitments.
