Mining Industry
Reliable, flexible, and low-carbon power generation for remote and industrial mining operations.
About the Mining Industry
The mining sector operates some of the most energy-intensive and remote facilities in the world, often located far from stable grid infrastructure. Mines require constant, high-capacity power to support crushing, processing, ventilation, water pumping, and camp operations — all while maintaining strict safety and environmental standards.
Traditional diesel generation has been widely used for decades, but it is costly, carbon-intensive, and subject to volatile fuel logistics. Modern gas engine power plants and flexible generation technologies now provide a cleaner, more efficient alternative. These systems can operate on pipeline natural gas, liquefied natural gas (LNG), or associated gas produced locally as a by-product of extraction.
By integrating microgrid control, gas engine power stations can coordinate multiple generation sources — including renewables and battery storage — to deliver secure, flexible, and low-carbon power. This hybrid approach enhances reliability, reduces operating costs, and supports the industry’s transition toward sustainable mining operations.
Benefits of Flexible Power Solutions for Mining Operations
• Reliable Power Supply: Delivers continuous, high-quality energy to support critical mining processes in remote areas.
• Flexible Operation: Rapidly adjusts output to match varying site loads and process requirements.
• Reduced Emissions: Gas and hybrid systems significantly lower CO₂ and particulate emissions compared with diesel.
• Lower Operating Costs: Improved fuel efficiency and reduced logistics costs from local or LNG-based fuel supply.
• Integration with Renewables: Enables seamless incorporation of solar or wind power for hybrid operation.
• Scalable and Modular: Systems can be expanded or redeployed as mining operations evolve.
• Enhanced Energy Security: Onsite microgrid control maintains stability even during external grid or equipment disturbances.
Energy Resilience in Mining
Power reliability is essential for mine safety and productivity. Interruptions can halt production, disrupt water management systems, and compromise ventilation. Gas engine-based power generation offers dependable onsite supply with fast response and high efficiency, ideal for both continuous and standby operation.
When integrated within a microgrid, these systems can balance multiple energy inputs — including renewables and battery storage — to ensure uninterrupted power in all conditions. The result is a robust, flexible power network capable of supporting 24/7 mining operations while reducing environmental impact and operational risk.

Gas Engine Power Generation
Gas engine power plants provide reliable and efficient onsite electricity generation for mining operations. Designed for remote and high-demand environments, they can operate continuously or as dispatchable units to support grid stability and manage peak loads. Modular gas power stations offer quick installation and scalability, with electrical efficiencies up to 45% and total efficiencies exceeding 80% when heat recovery is utilised. Using natural gas, LNG, or associated gas, these systems deliver cost-effective, lower-emission energy for both processing and auxiliary loads.
Flexible Generation
Flexible generation allows mining sites to adapt power production to dynamic operating conditions and demand fluctuations. Gas engine plants can start and reach full output within minutes, making them ideal for supporting variable mining loads or hybrid operation with renewables. They can operate in base-load, peaking, or standby mode, ensuring power is always available when needed. This flexibility improves efficiency, reduces fuel consumption, and enables participation in energy markets where grid export or load management schemes exist.
Microgrids and Hybrid Energy Systems
Microgrid systems combine gas engine power with renewable generation and energy storage, creating a resilient and efficient power network. Advanced control systems manage the balance between generation sources, maintaining stability even during grid outages or rapid demand changes. For mining operations, microgrids reduce reliance on fossil fuels, optimise energy use, and enable isolated or semi-grid-connected operation. This hybrid configuration supports long-term sustainability goals while ensuring consistent power for critical equipment and processes.
