Off-Grid Power for RJV
A 233 kWh battery and 30.6 kW of solar, installed and commissioned by our electricians, power RJV’s four northern workshop domes, wash pad and fuel tank, off the grid.
Innovation
Better Buildings, Smarter Energy, Healthier People
Remote camps run on diesel around the clock, in buildings that fight the heat. We’re building the alternative, and we’re proving it on our own sites first.

Proof First
Two Off-Grid Offices for RJV
Two 12 × 3 m transportable offices we made, delivered and connected, running on 12.2 kW of rooftop solar and a 24 kWh battery.
Our Own Off-Grid Site Set
An office, crib room and ablutions we built and run on a Pilbara mine site, on our own solar, battery and EV charging.
Our Buildings in Use Today
TCD buildings are working at Brockman 4, Brockman 2 and Esperance, and sixteen studios we made are in place at Harvey Caravan Park.
What We’ve Done So Far
Proven on Our Own Sites First
- We designed our own building: twice as thermally efficient as a standard transportable, made with our open box building method at our WA facility.
- We made two off-grid offices for RJV, running on 12.2 kW of rooftop solar and a 24 kWh battery.
- We installed and commissioned a 233 kWh battery and 30.6 kW of solar for RJV, powering four workshop domes, a wash pad and a fuel tank off the grid.
- We run a Pilbara dewatering set fully off-grid on our own solar and battery.
- We put the first mine-spec Tesla to work on one of our Pilbara sites.
- We built a camp power system that scales from a single building to a full camp.
- Our buildings are in use at Brockman 4, Brockman 2 and Esperance, and sixteen of our studios are in place at Harvey.
8 dBA
quieter, measured at Holcim, Aug 2025
10 dB is heard as about half as loud, so 8 dB is roughly 40% quieter to the ear: a busy office versus a quiet library. Better sleep for crews.

Where It Leads
This Is Where We’re Taking It
Most camp energy studies fix the supply. We fix the demand and the supply, so the rooftops do the work and there is no solar farm to clear.

The Full Numbers
More of the Model
Our own camp power system scales from a single building to a full camp, on any mix of grid, generator, battery and solar. Start with better buildings on existing power, add batteries, then solar, without rework.
