Against the backdrop of the deepening implementation of the dual-carbon strategy and the accelerated development of green mines, the electrification of open-pit mining is rapidly gaining momentum. Electric mining trucks, with their notable advantages of low energy consumption, zero emissions, and reduced noise, have become the mainstay of material transport in mining operations. However, the industry as a whole faces a pressing challenge: while electrifying mining trucks is relatively straightforward, the supporting power‑supply infrastructure often fails to keep pace.
Traditional grid‑connected power expansion is difficult, diesel generators are costly and heavily polluting, and fixed power stations cannot adapt to dynamic operating conditions—these supply‑chain shortcomings have become key bottlenecks hindering cost reduction, efficiency gains, and compliant operations in the mining sector. Ruisu Intelligent Technology’s mobile photovoltaic–mobile energy storage solution, with its core strengths of portability, round‑the‑clock reliability, stable output, and robust adaptability, precisely addresses the challenge of recharging electric mining trucks, offering a new, optimal pathway for advancing electrification in mining.
Five major pain points are holding back the electrification of open-pit mines.
Open-pit mining operations are characterized by unique conditions, and traditional power‑supply approaches are inherently ill‑suited to the specific demands of such mining activities. This mismatch is reflected in five fundamental contradictions:
1. Under extreme operating conditions, both battery performance and lifespan degrade significantly.
2. The mine area’s power grid has insufficient capacity, resulting in poor power supply stability.
3. Energy‑replenishment efficiency is out of sync with the production rhythm, directly impacting capacity.
4. Fixed facilities exhibit poor compatibility, resulting in high construction and operation‑maintenance complexity.
5. Insufficient coordination among energy systems results in substantial full‑cycle cost pressures.
Mobile solar-plus-storage systems: the optimal solution for mine energy replenishment.
Tailored to the unique operational characteristics of open-pit mines, Ruisu Intelligent Technology’s photovoltaic container‑plus‑mobile energy storage solution departs from conventional fixed‑site power‑supply approaches. Centered on modularity, mobility, and intelligent design, it offers four key advantages that precisely address the core needs of mining operations:
1. The entire machine is mobile and can be synchronized with the mining face for iterative operations.
The entire system employs a standardized container‑integrated design. The mobile photovoltaic unit is housed in a shipping container, featuring foldable storage and rapid deployment for power generation, and supports full‑container lifting and trailer transport. With no need for complex civil‑engineering construction, it enables efficient and convenient relocation and deployment, perfectly aligning with the continuous site‑moving requirements of mining operations. Moreover, the equipment is reusable, effectively addressing the issues of idle fixed‑site plants and wasteful reconstruction.
2. Intelligent coordination of solar and energy storage enables 24-hour stable energy supplementation.
Leveraging an intelligent microgrid dispatch system, the entire setup achieves autonomous, smart power management: during periods of ample daylight, the photovoltaic container generates and consumes its own electricity, directly charging the electric mining trucks, while any surplus power is simultaneously stored in a mobile energy storage system. On overcast days, at night, or during peak demand, the energy storage system automatically discharges to provide supplemental power, smoothing out fluctuations in high‑power charging loads and completely eliminating issues of unstable power supply and charging interruptions, thereby ensuring round‑the‑clock, uninterrupted operation of the mining trucks.
3. Green electricity replaces traditional energy sources, reducing costs while remaining compliant.
By replacing costly diesel‑generated power and industrial grid electricity with green photovoltaic solar energy, energy consumption costs at the mine are significantly reduced. This zero‑emission, low‑carbon energy supply model aligns perfectly with green‑mine construction standards, helping mining operations successfully pass environmental inspections and industry compliance reviews while breaking away from traditional high‑energy‑consumption, high‑pollution operating practices.
4. Industrial-grade protection, designed to withstand harsh mine‑site conditions.
The entire solar‑storage system features a mining‑specific protective design, offering dustproof, waterproof, high‑ and low‑temperature resistant, and vibration‑proof performance. It can withstand harsh operating conditions such as mine‑site dust, extreme temperature fluctuations, and exposure to outdoor sun and rain, ensuring stable operation with a low failure rate and significantly reducing subsequent O&M labor and material costs.
Three customized solutions, covering mining operations of all scales.
Based on the scale of different mining areas, grid conditions, and operational intensity, Ruishu Intelligent Technology has developed three foundational deployment solutions that support modular, flexible scalability, thereby meeting the diverse transformation needs of various mines:
1. Small-scale off-grid solution
Compatible scenarios: In small-scale mining areas, the number of haul trucks is limited, operations are conducted on a small scale, there is no reliable grid power supply, and solar irradiation conditions are favorable.
The solution centers on mobile, foldable photovoltaic panels as the primary power‑generation unit, paired with compact mobile energy‑storage modules and fast‑charging equipment tailored for mining trucks. The system operates independently of grid power and diesel generators throughout its entire lifecycle. During daylight hours, solar power directly charges the mining trucks, with excess energy stored in the batteries; on overcast or rainy days, the stored energy provides backup power, fully meeting the daily charging needs of small‑scale mining operations while enabling an electrification pilot project with minimal upfront investment.
2. Medium-sized solar–storage–diesel backup solution:
Compatible scenarios: In medium-sized mining areas, the haul truck fleet is of moderate size, and frequent cloudy or rainy weather combined with unstable lighting places high demands on power supply stability.
The plan expands the photovoltaic and energy storage modules, establishing an intelligent microgrid system that relies primarily on solar power and battery storage, with diesel generators serving only as a backup for extreme weather or emergency operating conditions. Daily operations are fully powered by green electricity, significantly reducing diesel consumption while balancing grid reliability with operational cost-effectiveness.
3. Large-scale grid‑connected photovoltaic–storage complementary solution
Compatible scenarios: Large open-pit mines, with a high number of haul trucks operating continuously around the clock, can be connected to the local grid and aim for long-term cost reduction and efficiency gains.
A large-scale, modular solar‑storage cluster has been deployed, operating in a dual‑mode configuration: “self‑consumption of photovoltaic‑generated power combined with grid‑supplied low‑tariff charging.” During the day, green electricity meets the bulk of the charging demand, while at night, grid‑supplied low‑tariff power is used to replenish the storage system. Intelligent dispatching ensures optimal energy allocation, significantly reducing the overall electricity costs for large‑scale mining operations and meeting the continuous, high‑intensity operational requirements of major mines.
Fully compatible across all scenarios, meeting diverse power requirements for various engineering applications.
Ruisu’s mobile energy storage solutions can meet the electricity needs of construction projects across the entire project lifecycle and in all operational scenarios.
