Africa's first 24/7 solar-plus-battery plant begins operation

The Kamoa-Kakula Copper Complex, Africa's largest copper mining operation, has successfully activated a groundbreaking solar-plus-battery baseload power plant. Developed by CrossBoundary Energy, this facility combines a 233-megawatt-peak solar farm with a substantial 526 megawatt-hours of battery storage. It began commercial operations on August 12, 2026, marking a significant milestone in renewable energy for the region. The plant is designed to provide a continuous supply of at least 30 megawatts of dispatchable renewable energy, ensuring reliable power for mining operations even during periods without sunlight.

This project stands out not only for its capacity but also for its rapid development timeline. From the signing of its power-purchase agreement in April 2025 to operational status in just 16 months, this facility exemplifies a shift toward faster implementation of renewable energy solutions in Africa. Industry studies suggest that similar utility-scale solar and battery projects typically require around 29 months to complete, highlighting the efficiency of this initiative. The Kamoa-Kakula complex is owned by a consortium that includes Ivanhoe Mines, Zijin Mining, the Congolese government, and Crystal River Global.

The on-the-ground implementation involved collaboration among various stakeholders, including mining companies and energy developers. Historically, the Kamoa-Kakula complex produced approximately 388,800 tonnes of copper in 2025 and has relied on hydropower. However, instability in the DRC's electricity supply has occasionally necessitated the use of diesel generators and power imports. The new battery system addresses these issues by storing solar power generated during the day for use at night or during cloudy periods, thus stabilizing the energy supply for the mine.

The broader implications of this renewable energy initiative extend beyond mining. By reducing reliance on diesel fuel, the facility aims to lower operational costs and minimize exposure to fuel price fluctuations. This project is part of a larger effort to enhance energy infrastructure in the DRC, a country rich in copper and cobalt resources but challenged by inadequate electricity and transport systems. The establishment of renewable energy sources at mining sites reflects a growing trend of companies investing in their own energy solutions to meet production demands amid global shifts toward sustainable practices.

Looking ahead, the Kamoa-Kakula complex plans to significantly expand its solar energy capacity. By the end of 2027, the facility aims to double its solar baseload supply to 120 megawatts. This expansion is crucial as copper becomes increasingly essential for various sectors, including electric vehicles and renewable energy systems. The developments at Kamoa-Kakula not only highlight the potential for renewable energy in mining but also signal a broader commitment to sustainable practices in the region, paving the way for future innovations in energy and resource management.
