Loading Solostar Port Energy
Global benchmarks
01
Electric truck charging
Dedicated charging for battery-electric heavy vehicles at and around the port estate.
02
High-power charging
Charging above 350 kW, including preparation for megawatt-class equipment.
03
Zero-emission cargo handling
Electrification of terminal tractors, cranes and yard equipment.
04
Shore power
Vessel-side electrical connection replacing auxiliary engine running at berth.
05
Renewable integration
On-site generation and contracted renewable supply feeding port operations.
06
Charging interoperability
Open access and roaming across operators rather than closed networks.
07
Port energy management
Coordinated management of generation, storage and load across the estate.
08
Public–private infrastructure models
Concession and co-investment structures for charging and grid assets.
01Global benchmarks
Port of RotterdamNetherlands
Europe’s largest port, with an explicitly stated energy-transition agenda spanning shore power, hinterland freight electrification and large-scale renewable and hydrogen infrastructure within the port estate.
Relevance to the Kandla concept — Demonstrates that the port authority itself can act as an energy infrastructure developer rather than only as a landlord — the structural question at the centre of the Kandla concept.

Benchmark references and public case studies are presented for comparative technical analysis only.
What the benchmark programmes have in common
01
Grid capacity is the schedule
In every benchmark programme, the pacing item is not charger procurement but electrical capacity — connection studies, transformation and, increasingly, storage to avoid new connection applications altogether.
02
Freight follows guaranteed availability
Logistics operators commit vehicles to routes where charging is contractually available, not merely present. Reservation and uptime guarantees do more to attract electric freight than raw charger count.
03
Energy management precedes expansion
Ports that installed chargers before a management layer generally rebuilt the control architecture within a few years. The intelligence layer is cheaper to build first.
04
Structure determines pace
Where the port authority took an infrastructure-developer role — directly or through a concession — deployment moved substantially faster than where charging was left entirely to third parties.
02National Opportunity · Indian Maritime Sector
Kandla, Gulf of Kutch, Gujarat · Major Port Authority
One of India’s highest-throughput Major Ports handling over 135 MMT of diverse cargo including dry bulk, liquid chemicals, POL, and containerized freight. Its strategic position at the head of the Gulf of Kutch, vast land availability, and direct link to the Western Dedicated Freight Corridor (WDFC) and DMIC make it India’s premier case for turnkey port electrification under the Harit Sagar Green Port Guidelines 2023.
Possible use cases
Heavy Freight Corridor
High-power 240–400 kW charging lanes along the Kandla-Gandhidham-NH41 heavy haulage corridor.
Port Authority Fleet
Dedicated Level 2 & fast DC charging court for harbor police, pilot boats, and administration duty vehicles.
Canopy Solar & BESS
Multi-megawatt solar canopies with containerized BESS peak shaving to mitigate DGVCL demand charges.
Green Tug & Shore Power
HT distribution integration for vessel cold-ironing berths and harbor craft battery swapping.
Single Command Center
Unified SCADA command center orchestrating energy dispatch, gate appointments, and ESG carbon accounting.

All ports
Prospective Indian port electrification landscape. Ports identified through public maritime data; none are currently contracted Solostar counterparties.
03Multi-Port Authority & APSEZ Framework
01
Mundra pilot
A single bounded deployment establishes the reference design: charging estate, energy architecture, management layer and measurement framework.
02
Multi-port digital platform
The same platform instance is extended to additional ports as separate tenancies, sharing infrastructure but segregating operational and commercial data.
03
Shared technology standard
One specification for chargers, protection, metering and communications across the network, so that spares, skills and procurement consolidate.
04
Fleet charging data layer
Logistics operators see one interface across every port in the network — availability, reservations, sessions and settlement.
05
National port-energy network
A coordinated charging and energy layer spanning the operator’s port portfolio, reported as a single ESG and utilisation picture.
