India is in the middle of a maritime expansion, and it is greening the sector as it grows. The policy framework is now explicit, the first onshore power supply berths are live, and the major ports are working through a phased build-out. Before the shore-power detail, it is worth seeing the scale of the trade that framework sits on.
India's maritime moment, in numbers
India runs one of the world's fastest-growing port sectors. Jawaharlal Nehru Port — Nhava Sheva, on the coast near Mumbai — is the country's largest container port, handling a record 7.05 million TEU in 2024, up about 12 per cent on the year and running above 90 per cent of capacity. Mundra, the Adani-run port in Gujarat, is India's largest port by total volume: it moved more than 200 million tonnes of cargo in 2024-25, the first Indian port to pass that mark, alongside roughly 7.4 million TEU. Paradip, Deendayal (Kandla), V.O. Chidambaranar (Thoothukudi) and Visakhapatnam round out a major-port system that the Sagarmala programme has been modernising for a decade.
India builds and crews ships as well as moving them. Cochin Shipyard, the country's largest, delivered the indigenous aircraft carrier INS Vikrant in 2022 and builds vessels up to around 120,000 DWT, and India remains one of the largest suppliers of officers and ratings to the world fleet. This is a maritime economy with the reach to make its port-emissions rules matter internationally.
India's green-port framework, and what it says about shore power
India's green-port direction is set out in three linked documents. The 'Harit Sagar' Green Port Guidelines, issued by the Ministry of Ports, Shipping and Waterways in May 2023, direct ports to develop shore-to-ship power in phases as part of a zero-carbon-emission goal. Above them sit the Maritime India Vision 2030 and the longer-range Maritime Amrit Kaal Vision 2047, which set port-level targets: raising renewables to over 60 per cent of port energy by 2030 and over 90 per cent by 2047, and cutting carbon per tonne of cargo by 30 per cent by 2030 and 70 per cent by 2047.
These are national targets rather than a single dated at-berth mandate of the FuelEU Maritime type, but the direction is unambiguous: shore-to-ship power is written into the plan for every major port, to be delivered in phases. India has also been developing its own national shore-power standard to sit alongside the guidelines.
Which Indian ports actually have shore power today?
Only a few, but the number is rising. V.O. Chidambaranar Port at Thoothukudi was the first Indian major port to offer shore-to-ship power, with a shore installation built around a static frequency converter across two berths. Paradip Port followed as the second major port to commission the capability, supplying full load to a berthed vessel in early 2026. Most other major ports — Nhava Sheva, Mundra, Deendayal, Visakhapatnam — are at the planning or early-build stage for vessel-scale onshore power supply, though many already provide shore power to smaller port craft and, at some ports, to naval and coast-guard vessels.
The honest picture, then, is a framework and targets firmly in place, a short but growing list of live berths, and a build-out running port by port. For an owner that means the mandate is visible well before the infrastructure reaches every berth — which is precisely the position in which forward engineering earns its keep.
Renewable ports and a hot-climate load
Two things make the Indian picture distinct. The first is that shore power here is being built as part of a renewables push: the Vision targets tie onshore power to a rising share of solar and wind at ports and to green-hydrogen hubs designated at V.O. Chidambaranar, Paradip and Deendayal, so the electricity a berthed ship draws is increasingly low-carbon at source rather than merely relocated combustion.
The second is climate. Indian ports work in high ambient temperatures for much of the year, which lifts the two most demanding parts of a container ship's berth load — reefer boxes and accommodation HVAC — above their temperate-port levels. A shore connection sized for a European winter can fall short of an Indian summer peak, so the load survey has to be run against the vessel's actual tropical operating profile, not a generic figure.
Why owners on India rotations should engineer the connection now
Because the build-out and the vessel work run on different clocks. A ship-side shore-power retrofit needs a load survey, a class-approved change to the single-line diagram, and long-lead electrical equipment — transformer, switchboard, cable — ordered against a dock date. That timeline is measured in months and competes for the same yard and equipment capacity as every other owner responding to the same regional shift. Doing the engineering while the Indian network is still filling in means the vessel is ready when its regular berths switch on, rather than waiting on a converter afterwards.
- A shore connection to IEC/IEEE/ISO 80005-1, so it interfaces with the compliant OPS berths India is commissioning
- Capacity surveyed against a hot-climate peak, with tropical reefer and accommodation-cooling demand included
- A clear read on which of your Indian berths are live, building or still planned for vessel-scale OPS
- Whether the berth or the ship carries any frequency conversion the vessel's configuration needs
- Class approval and long-lead procurement scheduled against the next available dock window
Frequently asked questions
- Which was the first Indian port with shore power?
- V.O. Chidambaranar Port at Thoothukudi (Tuticorin) was the first Indian major port to offer shore-to-ship power, using a shore installation built around a static frequency converter across two of its berths. Paradip Port became the second major port to commission the capability, supplying full load to a berthed vessel in early 2026. Other major ports are following in phases.
- Is shore power mandatory in India?
- Not yet as a single dated at-berth mandate. India's approach is set by the Harit Sagar Green Port Guidelines (2023) and the Maritime India Vision 2030 and Amrit Kaal Vision 2047, which require major ports to develop shore-to-ship power in phases and set renewable-energy and emissions targets. The obligation is arriving through this phased framework rather than one fixed deadline.
- What are the Harit Sagar guidelines?
- Harit Sagar — 'Green Sea' — is the set of Green Port Guidelines the Ministry of Ports, Shipping and Waterways issued in May 2023. They point Indian ports toward a zero-carbon-emission goal, including developing shore-to-ship power in phases, increasing renewable energy, handling greener fuels such as green hydrogen and ammonia, and cutting waste and water use.
- Does India's hot climate change how a shore-power retrofit is sized?
- Yes. High ambient temperatures raise a container ship's two heaviest berth loads — refrigerated containers and accommodation cooling — above temperate-port levels. A connection sized for a cooler climate can trip on an Indian summer peak, so the load survey should be run against the vessel's actual tropical operating profile before the transformer, cable and breaker are specified.
