What we've done
Case studies
CASE STUDIES – STEG has proudly partnered with some of Australia’s largest brands in delivering cost and carbon savings in off grid applications. We have over 150 live sites across Australia.
Cube MAX in action — Melbourne: 2 year deployment.
This Purple CUBE Max is coupled with an Aston Electric XL400 fuel-optimised diesel generator powering a major site compound on one of Victoria's largest infrastructure projects. The CUBE is also taking in solar energy from the site's pre-existing 96kW rooftop solar, further reducing operating costs.
Purple POD in action — Queensland 12 month deployment.
This Purple POD Core unit was recently deployed for a 12 month period powering portable buildings on a tier one construction site in Queensland. The unit was used in place of a 20 kVA diesel generator and delivered typical outstanding cost and carbon savings to the site.
Purple Skidibee in action — Pilbara: permanent deployment.
The above Skidibee array is one of 2 such installations in the North West of WA. The Skidibees feed 2 x Purple POD MAX compact hybrid systems, providing diesel-free operation of sensitive electronic monitoring equipment to a tier 1 miner. The Skidibee-Purple POD combo has reduced diesel operation at the remote sites to zero, whilst ensuring redundancy in the case of a prolonged weather event.

Scope-1 emissions, calculated from real consumption. Audit-grade, reporting-ready.
Remote dispatch, set-point control, fault alerts. The platform operates the asset, not just observes it.
