A remote copper mining camp in northern Chile is located in a desert area with no public power grid coverage, relying entirely on diesel generators for power supply. High fuel transportation costs, frequent generator failures, and severe noise and air pollution not only increase mining operation costs but also affect the living environment of on-site workers. The mining company urgently needs a stable, clean, and cost-effective off-grid microgrid solution to support the operation of mining equipment, living quarters, and safety monitoring systems.
Location/Time: Northern Chile, March 2025
Configuration: PCS: 550kW, BAT: 1300kWh, PV: 600kW, Backup Diesel Generator: 350kW
Load: Mining crushers, ventilation systems, water pumps, worker dormitory lighting/air conditioning, security monitoring, communication equipment
Operating environment: Remote desert mining area, extreme high temperature, strong sunlight, large dust, large power demand fluctuation
Operating modes: Off-grid operation, solar energy priority, energy storage system for peak load regulation, voltage stabilization and emergency power supply, diesel generator starts automatically during continuous cloudy days or peak mining load to ensure uninterrupted production.
The system adopts dust-proof, high-temperature resistant and anti-shock integrated design, which can adapt to the harsh desert mining environment and reduce equipment maintenance frequency. The intelligent energy management platform realizes real-time monitoring of power generation, energy storage and load operation, and optimizes power distribution according to mining production schedules. Solar panels are installed on the roof of the dormitory and auxiliary buildings, making full use of idle space.
Since the system was put into operation, the mining camp has achieved 24-hour stable power supply without production interruption. The annual fuel cost has been reduced by 65%, and the frequency of equipment maintenance has been reduced by 70%. The clean energy supply has eliminated noise and air pollution, improving the living and working environment of workers. This solution has become a model for green and efficient energy supply in remote mining areas.
