Solutions by site type

Three site types. Three different engineering problems.

Public car parks fight demand charges. Depots fight connection cost and queue times. Mines fight diesel. Each gets its own architecture — not a one-size-fits-all charger catalogue.

Destination charging that survives its own demand charges

On public sites, the tariff — not the hardware — decides profitability. A handful of simultaneous fast-charge sessions can set a rolling 12-month demand charge that erases a year of margin.

  • Mixed AC (7–22 kW) bays for dwell-time parking plus DC fast charging (60–150 kW+) for turnover bays
  • Battery-buffered chargers cap the site's peak draw — fast charging without a new transformer or a multi-year connection upgrade queue
  • Dry-type cast-resin transformers for basement and indoor installations
  • Load management across the whole car park from one EMS, with billing, OCPP roaming and uptime monitoring
Modelled result: battery peak-shaving pays for itself in ~3.3 years on demand-charge savings alone — before a single kWh is sold.

DC fast bays60–150 kW+

Revenue optionsown / share

Depot charging sized by schedule, not by fleet count

The naive design — one fast charger per truck — buys megawatts you'll never use at once. Smart overnight scheduling serves the same fleet from a fraction of the connection.

  • Sequenced DC fast charging (120–400 kW, shared power-pool dispensers) plus a bank of 22 kW AC for long-dwell vehicles
  • Rooftop solar + BESS stack energy savings on top of demand-charge avoidance
  • Worked example: 20 × 300 kWh trucks charged overnight by four 120 kW chargers on a 500 kVA supply — instead of a 2.4 MW connection
  • MCS-ready civil and switchboard design so today's depot accepts tomorrow's megawatt trucks
  • Zero-upfront Charging-as-a-Service available: we finance, you pay per kWh or per vehicle
Fleet modelling across local duty cycles: A$8.2k–22.5k saved per vehicle per year, and 72–203 t CO₂ per year off your Safeguard/Scope-1 ledger.

Solar–storage–charging microgrids that displace diesel

At remote sites, freight alone can be 40%+ of the delivered cost of diesel. An integrated microgrid cuts generator share from 100% to 30–50% while electrifying the light and haul fleet.

  • 3–10 MWp solar with 4–20 MWh LFP storage; existing gensets retained as backup with black-start capability
  • AC 7–22 kW and DC 60–120 kW for light vehicles; multi-gun DC up to 2.5 MW for battery-electric haul trucks — a shift-change top-up, not an overnight wait
  • Three-tier EMS: millisecond grid-forming stability, second-level dispatch and charge queuing, day-ahead economic optimisation
  • One integrator accountable for generation, storage, charging and controls — one throat to choke
  • Directly answers Safeguard Mechanism baselines and board-level ESG commitments
Modelled payback of 3–5 years against delivered diesel, before carbon liabilities are priced in.

Featured applications

Where charging is heading next — built today

Five scenarios we're engineering right now: charging that moves, plants that generate and store their own energy, power electronics that shrink the substation, multi-megawatt charging for the biggest trucks on earth — and fleets that sell energy back.

APP 01 · MOBILE DC

Mobile DC charging stations

A battery and a DC fast charger on wheels — deployed in days, not the 12–24 months a new grid connection can take.

  • Bridge charging while your depot waits in the DNSP connection queue — the fleet energises before the switchboard does
  • Events, construction sites, roadside rescue and seasonal peaks served with zero civil works
  • Recharges off-peak or from site solar, then relocates as your rollout advances
200–1000 kWh onboard60–240 kW DCtrailer / skid mounted
APP 02 · PV + ESS + EV

Integrated solar–storage–charging plants

Generation, storage and charging engineered as one plant behind a single connection point — not three systems bolted together.

  • Solar canopy or rooftop charges the battery through the day; the battery carries the evening charging peak
  • DC-coupled architecture cuts conversion losses and keeps the grid connection small
  • One EMS dispatches the whole plant against your tariff — self-consumption first, demand charges capped
single connection pointDC-coupled optiongrid-tied or off-grid
APP 03 · SOLID-STATE TRANSFORMER

Solid-state transformer charging hubs

The next substation is power electronics: an SST connects at 11–22 kV and converts straight to DC — replacing the line-frequency transformer and rectifier stack.

  • Fewer conversion stages mean higher plant efficiency at megawatt scale
  • A fraction of the footprint and weight of a conventional transformer-plus-rectifier lineup
  • A native MV-to-DC bus feeds chargers, BESS and solar directly — and can sell grid-support services back
MV-direct 11–22 kVnative DC buscompact footprint
APP 04 · 2.5 MW MINING

2.5 MW charging for battery-electric haul trucks

A 220-tonne haul truck carries a megawatt-hour-class battery. Charging it can't take all night — 2.5 MW turns it into a shift-change top-up.

  • Large-capacity static charging up to 2.5 MW per stall, via multi-gun or pantograph connection
  • Charge windows engineered around crib breaks and shift change — the trucks keep hauling
  • Integrated with the site microgrid so multi-megawatt draws don't destabilise an islanded network
up to 2.5 MW per stallpantograph / multi-gunmicrogrid-integrated
APP 05 · VEHICLE-TO-GRID

V2G: the parked fleet is the battery

A depot of electric trucks asleep overnight is a grid-scale battery you've already paid for. Bidirectional charging turns idle hours into revenue and resilience.

  • Bidirectional DC chargers export through the site connection — ISO 15118 signalling, AS/NZS 4777.2-compliant grid interface
  • Earn from NEM energy arbitrage and FCAS markets while the fleet sleeps — the EMS guarantees every vehicle its departure state-of-charge
  • Outage resilience built in: the fleet backs up the depot (V2B) before it ever sells to the grid

Commercial models

Own it, share it, or pay per charge

Charging infrastructure shouldn't force one balance-sheet decision on every customer. Pick the structure that fits — the engineering underneath is the same.

MODEL A

Turnkey ownership

You own the asset behind the meter. We design, supply, install and commission at a fixed price, then hand over with training and warranties.

Fits: owner-operators, mines, councils
MODEL B

Site partnership

You provide the site and power; we invest in and operate the chargers. Revenue is shared, and your car park earns from every session.

Fits: shopping centres, landlords, servos
MODEL C

Charging-as-a-Service

Zero upfront. We finance and operate the full system — chargers, storage, software — and you pay per kWh or per vehicle, with uptime guaranteed.

Fits: logistics fleets electrifying now
MODEL D

Equipment + O&M

Already have an installer or in-house electrical team? Take certified hardware, spare parts and our remote-monitoring O&M contract alone.

Fits: EPCs, IPPs, existing operators
MODEL E

Vendor finance

Hardware carried on the manufacturer's balance sheet: staged or deferred payments matched to deployment milestones or charging revenue — your working capital and bank lines stay free.

Fits: CPOs, dealer groups, multi-site rollouts

Compliance & funding

Built for Australian rules, funded by Australian programs

Federal and state programs are actively co-funding fleet and heavy-vehicle charging — ARENA's Driving the Nation has already committed over A$80M to truck charging alone. We build the funding case alongside the engineering one.
