- Kamoa Copper S.A. and CrossBoundary Energy have signed a power purchase agreement (PPA) to provide baseload renewable energy to the Kamoa-Kakula Copper mining complex, one of the largest copper mines in the world, situated near Kolwezi in the Democratic Republic of the Congo.
Kamoa Copper S.A. is a joint venture between Ivanhoe Mines, Zijin Mining Group, and the Government of the Democratic Republic of Congo, which owns a 20% stake in the company. The mining complex is the largest of its kind in Africa, with copper production capacity of approximately 600,000 tonnes per annum. The ramp-up of the new on-site direct-to-blister copper smelter is expected to commence in the second quarter of 2025.
This solar project is the first of its kind in Africa and will include a 222 MWp solar PV system and a 123 MVA/526 MWh battery energy storage system (BESS). The plant will provide a 30MW dispatchable renewable baseload energy supply to the mine, offsetting fuel generators and reducing carbon emissions by around 78,750 tonnes per year. CrossBoundary Energy will own and operate the plant, and Kamoa Copper will pay for the energy it consumes. The plant is expected to produce ~300,000 MWh of clean energy per year.
Whilst many mines have incorporated solar PV and BESS systems into their operations, the supply of baseload energy—a guaranteed power output at all times—is rare for solar PV and BESS, as the sector has typically been cautious of intermittency. However, due to the increasing efficiency of solar PV and the declining cost of BESS components, a renewable baseload system is now viable and cheaper than the diesel generators currently providing power to the mine.
Franck Alloghe, Business Development Director for CrossBoundary Energy, said, “This agreement represents a change in energy supply for mining operations, indicating that diesel or HFO generators are no longer the only viable option for guaranteed baseload power generation. We look forward to executing this project with the Kamoa Copper team. Baseload from the sun is here.”
Construction of the renewable energy facility is due to start in August 2025.
The Kamoa Copper mining complex is one of the largest and fastest-growing copper complexes globally, with significant energy needs. The company’s commitment to incorporating renewable energy components underscores its ambition to lead the sustainable mining industry and energy transition.
