SOLOSTAR PORT ENERGY™ is one
architecture, not six procurements.

Six modules across a physical, an energy and a digital layer. Each is deliverable on its own; together they behave as a single system, which is what makes the port’s energy estate controllable rather than merely installed.

02Heavy freight electrification

Beyond cars. Electrifying
port logistics.

Passenger charging is a convenience. Freight charging is a competitive question: ports that can guarantee high-power charging will retain electric freight, and ports that cannot will watch it route elsewhere.

Deployment roadmap

Port

Gate, terminal and berth-side movements. High-power charging at the point of dwell.

The infrastructure this requires

01
High-power charging
180–400 kW charging positioned where heavy vehicles already stop, not where they must divert.
02
Megawatt Charging System
Civil works, cable routes and substation headroom provisioned in phase one for MCS equipment later.
03
Overnight depot charging
Lower-power charging across long dwell periods — the cheapest energy in a freight operation.
04
Opportunity charging
Charging during mandated driver rest periods and scheduled gate waiting.
05
Charging reservations
Committed arrival windows so fleets can plan routes around guaranteed availability.
06
Truck queue management
Digital allocation of lanes and bays, with driver notification and re-sequencing.
07
Fleet APIs
Programmatic access to availability, reservations, sessions and settlement for logistics operators.

03Safety & infrastructure engineering

High power, coastal conditions,
an operating port estate.

Charging at 400 kW inside a working port is an electrical and civil engineering problem before it is a technology one. Each domain below has a defined scope and a defined approvals pathway.

Sub-cycle fault clearing across 13.8kV/34.5kV and 480V networks

Medium-Voltage & Protection

ELE-01Selective coordination study per IEEE 242 (Buff Book)
ELE-02Arc flash risk assessment and labeling per NFPA 70E / IEEE 1584
ELE-03Ground Fault Protection of Equipment (GFPE) on all charging feeders
ELE-04Emergency power off (EPO) loops with lockable, visible disconnect switches

Final infrastructure design shall be subject to detailed engineering, Central Electricity Authority (CEA) safety regulations, and applicable Indian/IEC standards.

04Interoperability

Infrastructure without
vendor lock-in.

An Authority that procures charging infrastructure should not thereby procure a permanent supplier. The architecture is specified so that hardware, software and operator can each be replaced independently.

01
Open Charge Point Protocol (OCPP)
Charging dispensers are procured against open management interfaces so the terminal operator is never vendor-locked to a single hardware manufacturer.
OCPP 1.6-J / 2.0.1 Open Alliance Certified
02
Automated Demand Response
Bi-directional automated load shedding and demand-response signaling with regional transmission operators (CAISO, PJM, ERCOT, NYISO).
OpenADR 2.0b Profile Certified
03
Terminal Operating System (TOS) Dispatch
Drayage arrival schedules, vessel discharge manifests, and container gate appointments are ingested directly from terminal systems (Navis N4, Tideworks).
Real-time Webhook / RESTful JSON / gRPC
04
SCADA & Substation Protocol Gateway
Feeder set-points, transformer temperatures, and breaker telemetry exchange directly with port industrial SCADA networks.
Modbus TCP / DNP3 / IEEE 1547-2018
05
Commercial Fleet Fueling & Toll Settlement
Commercial drayage lanes support credit cards, contactless NFC, and major US commercial fleet fueling cards with automated monthly settlement.
WEX / Comdata / PCI-DSS Level 1 Gateway
06
Enterprise ERP & Accounting
Substation kilowatt-hours, demand savings, utility bills, and concession revenues are pushed automatically to enterprise ERP systems (SAP, Oracle).
Enterprise API & SEC / GAAP Accounting Feeds
07
Automated Vehicle Identification & Plug & Charge
Instantaneous cryptographic handshake and automated billing upon cable connection, with RFID and J1939 telematics as fallbacks.
ISO 15118-2 / ISO 15118-20 Plug & Charge

05Cybersecurity

Six layers between the connector
and the control surface.

Charging infrastructure is operational technology attached to a port network. It is treated accordingly: segmented, authenticated, monitored, and able to fail safely when the link is lost.

Layer 1 controls · Dispenser / Asset Edge

Hardware Root of Trust & TPM 2.0 cryptoprocessors
Digitally signed firmware updates with rollback prevention
Local autonomous fail-safe limits on communication loss

Role-based access

Permissions scoped by function and by site, reviewed on a defined cycle.

Multi-factor authentication

Required for every privileged and control-capable role.

Audit trails

Control actions recorded immutably with actor, time and prior state.

Backup and recovery

Documented recovery objectives, with restores tested rather than assumed.

Controls describe the architecture proposed for this concept. No certification, accreditation or third-party assurance is claimed or implied at this stage; formal assurance would follow the Authority’s own information-security requirements.

06Sustainability

Make decarbonisation
measurable.

A sustainability claim is only as good as the data behind it. Every indicator the platform reports is derived from metered data with a published calculation basis, so it can survive an audit rather than a press release.
