Yadlamalka sits in the northern reaches of South Australia, between Hawker and Leigh Creek. The region is known for its wide-open gibber plains, artesian water sources and long-running pastoral history. Yadlamalka’s roots date back to the late 1800s, forming part of the network of remote outback properties that supported Australia’s early pastoral development. Its isolation, dry climate and long distances from major townships have always shaped how these properties access water, manage livestock and secure reliable off grid power.

Remote Bore Water Pumping Sites

On large rural properties, a reliable water supply is essential. Yadlamalka has two bore pumping sites located at different points across the property, each critical to daily livestock operations. Both sites were running ageing infrastructure that had become costly and increasingly unreliable. Over time, these systems could no longer keep up. MyEnergy was brought in to assess both pumping locations and design a tailored off grid power solution for each site.

Custom Off Grid Power for Harsh Outback Conditions

After a detailed site visit, MyEnergy designed complete off grid power systems for both pumping locations. Each system was built into a custom steel cabinet, fully insulated, vermin-proof and air-conditioned to ensure stable operation in extreme heat and dusty outback conditions. Every component was fitted out, configured and tested at MyEnergy’s headquarters before transport to site.

With no suitable roof structures available, ground-mounted solar arrays were installed using heavy-duty S-Rack mounting. This approach makes the most of open land, delivering strong solar production while standing up to wind, heat and long-term exposure.

These off grid power systems were positioned and connected at each pumping site alongside new generators, allowing reliable solar-battery operation with generator support only when required.

Keeping Yadlamalka Powered for Tomorrow

Both pumping stations now operate with dependable off grid power, combining substantial battery storage with generator backup if ever required. By drawing on ground-mounted solar arrays, advanced monitoring and fully protected system cabinets, each site now benefits from reliable pumping capability in one of Australia’s toughest environments.

For remote outback properties across Australia, off grid power isn’t optional, it’s essential. MyEnergy designs off grid power systems that stand up to heat, dust, distance and years of hard use. Projects like Yadlamalka highlight the value of well-planned off grid power: systems built to work today, built to adapt and built to keep remote operations moving forward.
