Operator: Deendayal Port Authority (DPA)
Location: Kandla, Gulf of Kutch, Gujarat
Port type: Major Port Authority
Concept status: Primary concept case

01Strategic context

Why this port,
and why now.

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.

Kandla sits at the vital intersection of three structural shifts in India’s maritime logistics: heavy road-freight volumes concentrating around a small number of toll gates, Indian commercial vehicle OEMs (Tata Motors, Ashok Leyland, Olectra) deploying heavy battery-electric trucks, and land-rich coastal estates exceptionally well suited for high-insolation solar generation.

Solostar’s integrated blueprint solves the utility interconnect bottleneck. Uncoordinated multi-megawatt truck charging risks triggering immense DISCOM peak demand penalties and localized transformer saturation. By pairing high-power dispensers directly with on-site solar, containerized BESS, and algorithmic load dispatch, Solostar delivers guaranteed fleet turnaround while reducing net levelized energy costs.

Aligned with the Ministry of Ports, Shipping and Waterways (MoPSW) Harit Sagar Guidelines and Maritime Amrit Kaal Vision 2047, this blueprint is structured for immediate execution under EPC, PPP Concession, or Charging-as-a-Service (CaaS) frameworks.

Staff & Administration EV Hub

Long-dwell Type 2 AC & DC charging under solar canopy

Port administration, operational staff, and visitor parking converted into a covered clean charging court. Long dwell times make this ideal for solar time-shifting: charging sessions modulate automatically across working shifts to absorb on-site solar generation and avoid DISCOM peak demand charges.

Workforce parking: 7.4 kWType 2 AC
Workforce parking: 22 kWType 2 AC
Executive / Visitor: 24 kWCCS-2 DC

Port Operational & Security Fleet Depot

Mission-critical DC fast charging for port operations

The operational core of the marine terminal. CISF security vehicles, harbor police, maintenance utilities, and pilot vessels operate under strict dispatch windows. Charging is scheduled deterministically against duty rosters—emergency response and pilot vehicles receive highest feeder priority.

Utility fleet: 60 kWCCS-2
Security & Patrol: 120 kWCCS-2

Commercial Fast Charging Plaza

Transactional fast DC charging for commercial logistics

A high-throughput revenue court positioned along the port gate approach road for third-party logistics support vehicles, delivery vans, staff shuttles, and contractor trucks. Multi-standard commercial payment gateways and fleet accounts generate strong revenue to support infrastructure capital costs.

Commercial DC: 60 kWCCS-2
High-Power DC: 120 kWCCS-2
Ultra-Fast DC: 180–240 kWCCS-2

Heavy Freight & Drayage Yard

High-power multi-axle freight charging on pull-through lanes

The heavy-tonnage logistics engine. Multi-axle electric commercial trucks, POL tankers, and container haulers require high energy transfer without blocking port gates or staging yards. Wide pull-through lanes allow full tractor-trailer combinations to charge without uncoupling, backed by virtual queuing to eliminate truck idling.

Multi-Axle Heavy Duty: 240 kWCCS-2
Heavy Drayage Fast: 400 kWCCS-2
Megawatt Charging (MCS): 1.2 – 3.75 MWMCS Ready
Yard Hostlers: 120 kWCCS-2

Microgrid Substation, BESS & SCADA Hub
