APPLICATION
Mining Microgrid
Reliable off-grid power for mining operations. Solar-diesel hybrid systems reduce fuel costs by 50%+ while ensuring 24/7 operations.
Mining Microgrid
Powering Mines Smarter
Mining operations in remote locations face extreme power costs and logistics challenges. Diesel fuel alone can represent 20-30% of operational expenses. Our hybrid microgrid solutions integrate solar PV and battery storage with your existing generators to slash fuel consumption while maintaining 100% operational reliability.
Designed for harsh environments — dust, vibration, altitude up to 5000m, and temperatures from -30°C to +50°C. Every system is engineered to your specific mine profile and load characteristics.
Mine Power Solutions
Load Following
Intelligent controller matches generation to variable mining loads — crushers, conveyors, ventilation, and processing plants — without generator oversizing.
Fuel Savings
Diesel reduction is project-dependent and is assessed from the load profile, solar resource and operating strategy. Battery storage handles peak loads so generators run at optimal efficiency or shut off completely.
Remote Operation
Satellite-connected SCADA with automated alerts. Monitor and control your power system from anywhere — reduce site visits and response time.
Scalable Design
Start with core loads and expand as the mine grows. Containerized modules allow fast deployment and easy relocation between sites.
Harsh Environment
Heavy-duty enclosures rated IP65, dust filters, vibration dampening, and wide-temperature components for mining conditions.
Compliance
IEC 62271, ISO 8528, and local mining safety regulations. Full documentation package for regulatory approval.

Why Hybrid Microgrids Are the New Standard for Mining
Mining operations have one defining constraint: isolation from the grid. Whether you’re 2 km or 2,000 km from the nearest power line, you need reliable, cost-effective electricity. For decades, that meant diesel generators — and all the costs and risks that come with them. Today, hybrid solar-battery-diesel microgrids cut diesel consumption by 60-80% while improving uptime and reducing HSE exposure.

Mining Site Power Challenges
🚚 Fuel Logistics Cost
Diesel transport to remote sites costs $0.50-$2.00/L above the base price. A 1MW mine consumes 250,000L/month — that’s $125K-$500K in logistics alone.
⚠ HSE & Spill Risk
On-site diesel storage is the #1 cause of mining environmental incidents. Reducing diesel on-site cuts both regulatory exposure and insurance premiums.
🔌 Generator Maintenance
24/7 generator runtime means service every 250 hours. Hybrid systems run generators 4-6 hours/day, extending service intervals to 1,000+ hours.
🌡 Extreme Climate
Mines operate from -40°C (Arctic) to +55°C (Sahel). Our equipment is rated for the full range with derating and climate-controlled enclosures.
📡 Dust & Vibration
Conveyor dust and blasting vibration damage sensitive electronics. Our systems use IP65 enclosures, conformal coating, and shock-mounted equipment.
📊 Demand Variability
Crusher ramps, ventilation surges, and shift changes cause 3-5× demand spikes. Battery storage smooths these spikes, allowing smaller generators.

A typical mid-tier gold mine operating 24/7 at high altitude replaces its diesel plant with a hybrid microgrid. Diesel consumption and delivered fuel cost vary by site, but reductions of 60% or more are typical.
Typical results: diesel consumption falls by more than 60%, payback is usually between 2 and 4 years, and nighttime noise drops noticeably, improving camp conditions.
Annual CO₂ reductions can be substantial, and projects may qualify for carbon credit programs.
