Value

$4 million

A technically complex installation forming part of the landmark Agnew Hybrid Renewable Project – Australia’s largest hybrid renewable energy microgrid and the first to utilise large-scale wind generation at a mining operation.

PHE Group was engaged to deliver the full electrical installation for the 20MW gas and diesel-fired power station forming part of the Agnew Hybrid Renewable Project – the first remote mining operation in Australia to utilise a hybrid modality, integrating gas, diesel, wind, solar, and battery storage assets. Delivered for Cummins under the broader Agnew Hybrid Renewable scope, the power station provides reliable, low-emission energy to the Gold Fields Agnew Gold Mine.

The works required careful planning and execution in a remote location, integrating with renewable generation systems and accommodating the complex logistics of transporting materials, equipment and personnel to site.

Project Scope

Delivered the full E&I package, including backbone and ancillary cable support systems to integrate all major plant components.
Completed remote radiator installation to ensure optimal generator cooling performance.
Delivered MV, LV, DC, control, and communications cabling to support seamless power distribution and system control.
Installed auxiliary transformers and 11 kV RMU systems to enhance site-wide power reliability.
Carried out Balance of Plant electrical works, including power to air compressors, lube oil systems, operations rooms, storage facilities, and lighting.
Installed hazardous area instrumentation for gas skid and generator, ensuring compliance with relevant safety standards.
Installed and wired UPS and protection systems to safeguard critical operations.
Provided QA commissioning support across both Stages 1 and 2, ensuring quality and performance benchmarks were met.

Outcomes and Benefits

Supported Australia’s energy transition by applying disciplined execution and practical expertise across hybrid power systems, resulting in a reliable, high-performance power station that underpins critical mining operations through more sustainable generation.
Delivered safely, on time, and without incidents, reinforcing PHE’s capability in executing E&I works within highly regulated, technically demanding environments.

Overcame logistical challenges associated with a remote WA location by carefully managing equipment, materials, and personnel, particularly when working in and around high-risk generation infrastructure.
Early planning de-risked interface works, staged electrical systems to align with commissioning, and enabled other contractors to progress safely and efficiently.
Client re-engagement to install an additional generator reflected confidence in PHE’s delivery and the performance of the project team.
