In today’s resource-conscious world, the push for greener operations extends beyond cities and into some of the most remote and rugged locations—like mine sites. Mining companies face a dual challenge: powering heavy operations in off-grid environments while simultaneously reducing their environmental footprint.
The solution? Deployable, hybrid power systems that combine renewable energy with traditional backup sources. And leading the charge is the Makinex Renewables Hybrid Power System (HPS).
Why Off-Grid Power Matters in Mining
Mining projects often operate far from existing power infrastructure, where grid access is unreliable—or nonexistent. Diesel generators have long been the default solution, but they come at a high cost, both financially and environmentally. As the industry moves toward more sustainable operations, off-grid hybrid systems like Makinex HPS offer a smarter alternative.
The Makinex HPS is a fully integrated, modular system that combines solar power, battery storage, an inverter, and a diesel generator to deliver uninterrupted, grid-like power—anywhere, anytime. It's easy to deploy, and engineered to slash diesel consumption without sacrificing performance.
Case Study: Meandu Mine Transmission Line Relocation
A prime example of the HPS in action is its deployment at the Meandu Mine Transmission Line Relocation Project in Queensland, Australia. Operated by Stanwell Corporation Limited, Meandu Mine required a new 4.6km section of a 275kV transmission line to support future mining operations, particularly the proposed King 2 East (K2E) project. Downer was contracted to complete the relocation works, while Kennards Hire provided the Makinex HPS to support power needs on-site.
The Project Scope
-
Construction of 15 new 275kV transmission towers along a 4.6km route
-
Removal of a decommissioned 3.8km line section
-
All works located in a remote area with limited power infrastructure.
Why Makinex HPS Was the Right Fit
Deploying the Makinex Renewables HPS was a game-changer for the project. Here's why:
✅ Rapid Deployment & Portability
The HPS can be quickly transported and set up even in challenging terrain. It integrates seamlessly with temporary worksite infrastructure, reducing downtime and eliminating the need for extensive site prep.
✅ Diesel Reduction = Emission Reduction
Over a 12-month period, the HPS helped the project save 10,208 liters of diesel, slashing consumption by 77.9% compared to traditional generators. This resulted in a 27.5-ton reduction in CO₂ emissions.
✅ Cost and Risk Efficiency
Beyond environmental impact, these savings deliver meaningful cost reductions. The system’s built-in redundancy (solar, battery, diesel) also minimises downtime caused by weather or grid failure—critical for keeping mining operations on schedule.
Leading the Shift to Sustainable Mining
The success at Meandu Mine underscores how Makinex Renewables HPS is more than just a backup solution—it’s a cornerstone of next-generation mining. As more sites seek to balance performance with sustainability, off-grid hybrid systems like the HPS will be essential to powering the future of the industry.
