Case Study


A small remote Aboriginal Community in the far North-West of Western Australia is currently spending $1,000 per week on diesel for their power generation.


Install a C Class Power Box on a Financed Lease.


This can result in weekly diesel fuel savings of $460 ($24,000 per annum).


The introduction of a C Class Power Box into this remote community could aid in the provision of a reliable power source that is not impacted by weather; allows remote access to much needed services such as medical attention, education and judicial and with the diesel fuel savings carry out much needed maintenance, infrastructure or community improvement.
