Renewables & battery energy storage.
Solar PV, battery storage and microgrids — designed with the rest of the electrical system, so connection, protection and metering work from day one.
Aurum designs renewable generation and battery energy storage systems (BESS) for buildings, developments and remote sites. Systems are sized from real load data and designed alongside the main electrical installation, rather than bolted on at the end.
From rooftop PV on apartment towers to solar, battery and generator microgrids at remote Pilbara homesteads, Aurum’s engineers handle feasibility, design, authority connection and commissioning support.

Frequently asked questions
What is a BESS?
A battery energy storage system stores electricity — usually from solar PV or the grid — and releases it when needed, to reduce peak demand, provide backup power or increase the use of on-site solar.
Do you design off-grid and microgrid systems?
Yes. Aurum designs solar, battery and generator microgrids for remote sites, including maximum demand analysis, feasibility and detailed design.
Can you handle the network connection?
Yes. Aurum prepares embedded generation applications and designs the protection and export arrangements the network operator requires, including Western Power in WA.
