Ivanhoe Mines is preparing for a significant increase in power requirements at the Kamoa-Kakula mine complex as it readies to commission the facility’s smelter in May 2025. By 2026, when all phases and the smelter are fully operational, electricity demand is expected to rise to approximately 240 MW, up from 130 to 140 MW in March 2025.

In a press release dated April 7, Ivanhoe has outlined its plans to meet this growing demand and transition the complex to green energy by 2026. 

Last month, 100 MW came from hydroelectric sources. Half of the input came from Zambia or Mozambique,  and the other half was produced on-site, by diesel generators. Following a recent agreement, hydroelectric imports have increased from 50 MW to 70 MW, with further expansion to 100 MW expected soon.

The commissioning of Inga II turbine 5 in the third quarter of 2025 will add another 50 MW of hydroelectric power, potentially bringing the total hydropower supply to 200 MW if imports are maintained at 100 MW. Additionally, Ivanhoe plans to launch a solar project in August 2025, which will provide a constant 30 MW of power through a 222 MWp photovoltaic solar power plant coupled with a battery storage system. The project falls under a recent agreement between Kamoa Copper, which owns the Kamoa-Kakula complex, and CrossBoundary Energy, a clean energy developer.

“This enhanced power capacity has bolstered confidence in finalizing the commissioning of the smelting furnace,” reads the April 7 release. According to this source, the smelter should produce its first 99.7% purity copper anodes by July 2025. Ivanhoe projects reaching around 80% of the smelter's capacity by year-end, with power consumption rising from 45 MW at start-up to 70 MW at full capacity.

By 2026, Ivanhoe aims to exceed annual copper production of 600,000 tonnes with the completion of Project 95, which seeks to optimize copper concentrate recovery to 95%. This initiative could add 30,000 to 40,000 tonnes of concentrate annually, following projected production of between 520,000 and 580,000 tonnes in 2025. After reaching 437,061 tonnes in 2024, Ivanhoe’s strategic investments in renewable energy and operational efficiency are set to drive significant growth in copper output.
