Vessel-schedule aware
Kaasai ingests berthing schedules from port management systems via API. Dispatch plans are built around vessel arrivals — not generic time-of-use slots. When a vessel is delayed, the platform recalculates automatically.
Shore power, vessel batteries, port grid — one operating system.
Port electrification creates the same energy orchestration problem as a large fleet depot — but with tighter grid constraints, variable vessel arrival schedules, and harder regulatory targets. Kaasai FlexCharge manages it all from a single platform, across every berth and vessel class.

The challenge
Shore power is the fastest-growing energy load at ports — and the hardest to predict.
Vessel arrival times shift. Shore power demand spikes. Grid capacity is finite and expensive to upgrade. BESS is being deployed at ports and ferry terminals to smooth the load — but without an orchestration layer, it's manually operated, mis-timed, and leaving arbitrage revenue on the table. Meanwhile FuelEU Maritime, ETS and CII are tightening the obligation to report and reduce. Kaasai connects shore power, port BESS, vessel telemetry where available, and grid data into a single orchestrated system.

Balance vessel load against BESS and grid limits
A live power-flow diagram across the port: grid → BESS → shore power → berth loads. ISA envelope headroom is always visible, so operators know exactly how much spare capacity exists before the next vessel arrival — and the system pre-positions BESS accordingly.

- ISA envelope with vessel-arrival-aware headroom
- BESS pre-positioning ahead of scheduled arrivals
- Solar integration for ports with generation

Dispatch
AI schedules BESS around arrivals and grid pricing
Kaasai ingests the vessel schedule and dispatches BESS charge/discharge cycles to minimise grid cost, hold headroom for arrivals, and participate in DSR or ancillary markets during quiet berth periods. The AI briefing shows operators exactly what's planned and why — daily.
- Vessel-schedule-aware BESS dispatch
- ToU and wholesale price arbitrage off-peak
- DSR / ancillary participation during low-demand
- AI daily briefing of planned cycles and forecasts

Proven at Southampton: V2X eFerry charging with Artemis and Red Funnel
Kaasai led the Clean Maritime Demonstration Competition Round 6 'Smart Shipping — Multi Asset Port Power Optimisation: V2X' project, demonstrating the technical and commercial feasibility of scalable V2G in a constrained UK port. The system orchestrates a 490 kVA bidirectional charger, a 1.5 MWh BESS and an EF-24 high-speed passenger eFerry — within local grid limits and while unlocking flexibility revenue.
- Digital twin connecting to live port asset APIs and protocols within 7 days of deployment
- Linear-programming optimiser scheduling multi-asset bidirectional charging for lowest TCO
- OCPP 2.0.1 V2G charging profiles created and dispatched by Kaasai's CPMS
- Planned-vs-actual tracking, SoC deviation detection and adaptive rescheduling over a 7-day horizon
- KPI reporting: departure risk, fulfilment, grid compliance, CO₂ reduction, revenue earned
- Validated against DSO, NESO, FFR, BM and wholesale flexibility markets
