Rugged connectivity
Kaasai connects over cellular, Wi-Fi, or site ethernet. Edge gateway options for remote locations. Data syncs to Azure when connection is available and buffers locally when it isn't.
Power every site. Cut every fuel bill. One platform.
Construction sites run some of the most dynamic, off-grid and grid-limited energy loads in industry. Kaasai FlexCharge manages temporary power, BESS, EV plant charging, and generator dispatch from a single platform — cutting diesel dependence and keeping projects on schedule.

The challenge
Construction energy is invisible, expensive, and almost always diesel-first.
Temporary power is procured by the week, generators run regardless of load, and EV plant charging is either absent or unmanaged. Fuel bills are the second-largest site cost after labour — and emissions reporting is manual, if it happens at all. Kaasai connects temporary grid connections, site BESS, EV chargers, and generator sets into a single orchestrated system. The result: less diesel, lower cost, and audit-ready carbon data from day one.
Platform
Three modules built for the way construction sites actually run.
Manage
Every power asset on site, in one inventory
Temporary grid connections, generators, site BESS, EV chargers, and solar welfare units in a single searchable registry. Drill into fuel consumption, charge session history, and maintenance schedules without leaving the platform.
- Generator inventory with fuel log and runtime tracking
- Site BESS registry with SoC, SoH and cycle log
- EV plant charger mapping with session history
- Solar welfare unit generation and offset tracking

Orchestrate
Balance site load across grid, BESS, and generator
A live power-flow diagram across the site: grid → BESS → generator → load → EV chargers. Operators see exactly where energy is coming from, how much headroom exists, and when the next EV plant shift will spike demand — so the system pre-positions BESS or throttles non-critical load before a generator starts.
- Site-wide power flow visualisation
- Generator auto-start threshold with BESS pre-positioning
- EV plant charge scheduling around peak loads
- Solar welfare integration for daylight offset

Dispatch
AI schedules BESS and EV charging around site load and fuel cost
Kaasai ingests the construction programme and dispatches BESS charge/discharge and EV plant charging to minimise generator runtime, cut fuel bills, and avoid grid connection breaches. The AI briefing shows operators exactly what's planned and why — daily.
- Programme-aware EV plant charging windows
- BESS dispatch to minimise generator runtime
- Grid import optimisation against connection limits
- AI daily briefing of planned cycles and fuel forecast

Fit
Built for the realities of temporary, dynamic, and hard-hat environments.
Emissions reporting from day one
Diesel offset, grid import emissions, and solar welfare contribution are tracked automatically — exportable for project carbon reporting and client ESG requirements. No manual aggregation.
Works with rented and owned equipment
Generators from any hire firm, BESS from any manufacturer, EV chargers from any provider. Kaasai connects via standard protocols. 13+ data stream types. 140 assets integrated in 7 days at first deployment.
