Recently, Beifang International’s Lamika source-grid-load-storage integrated project in the Democratic Republic of the Congo (DRC) has officially passed the owner’s inspection and was successfully handed over, marking a complete end to the project’s construction. It also injects strong momentum into the local mining area’s green, smart power supply, showcasing Beifang International’s contracting strength and technical advantages in the international new energy sector.

Throughout the entire construction process, the project vividly demonstrated “Beifang speed” and “Beifang quality.” With a total construction timeline of only 8 months, facing multiple challenges such as rain-season construction disruptions in the DRC, long logistics and transportation cycles, and complex equipment commissioning, the project team pre-arranged the construction organization design in advance and formulated precise, dedicated breakthrough plans. With professional project management capabilities and efficient execution, it successfully achieved grid-connected power generation and efficiently completed project implementation—proving the undertaking with solid work.

The project’s construction scale includes a 50MW photovoltaic power generation system and a 100MWh energy storage facility. It innovatively integrates grid-forming energy storage technology to enable coordinated dispatch among photovoltaic, energy storage, utility grid, and diesel power generation. It has successfully built a truly integrated smart power supply system for the mining area. The system has millisecond-level fault response and isolation capabilities, enabling precise coordinated control of source, grid, load, and storage. It smoothly meets the core design goal of “no production downtime during power outages, and limited power can still ensure supply” in a weak-grid environment, providing a solid guarantee for stable power supply for mine production.

As a benchmark project in the DRC’s energy sector, this project carries the significance of two-fold breakthroughs: it is both the country’s first photovoltaic power station to use a single-axis flat-tracking system, where intelligent solar tracking technology improves power generation efficiency by more than 15% compared with traditional modes; and it is also the largest-scale grid-forming photovoltaic-storage integrated system already put into operation in that country. It can safely and efficiently accomplish seamless switching among the utility grid, photovoltaic-storage, and diesel generation—providing a reliable, replicable, and scalable reference for remote mining areas to integrate green energy and achieve smart power supply.

The project’s ecological and economic benefits are also significant: its average annual delivery of clean electricity is approximately 85 million kWh, which can greatly reduce electricity costs for mines. Each year, it can save about 34k tons of standard coal and reduce carbon dioxide emissions by about 80.7k tons, helping the local area achieve green and low-carbon development. At the same time, the smart power supply system effectively avoids damage to mine equipment caused by frequent on/off cycling of the utility grid, further reducing mine operation and maintenance costs, and achieving an organic unity of ecological, economic, and social benefits.

The successful construction, inspection, and handover of this project are another important outcome of Beifang International’s in-depth implementation of the “five-in-one” coordinated development strategy of Beifang Company, leveraging system-level coordination advantages. It is also a positive contribution made by the company’s power business sector to ensure power supply for mines within the organization.

Looking ahead, Beifang International will rely on specialized operation and maintenance capabilities and the multi-energy coordinated dispatch system built through the projects, to do a good job in operating and maintaining the projects. Under the premise of ensuring stable power supply, it will promote both improved energy utilization efficiency and increased economic returns.
