DHYBRID BESS at Kamoa-Kakula: hybrid solar baseload lessons for mine power engineers

30 Second Briefing
Kamoa-Kakula, Africa’s largest copper mine, has been running on solar baseload since 12 August, with the new plant displacing about 4 million litres of diesel in its first month, equivalent to roughly US$11 million in fuel savings. DHYBRID Power Systems GmbH engineered the battery energy storage system (BESS) and supplies its Universal control platform to stabilise the hybrid power system and manage dispatch. For mine operators, the project shows large-scale solar plus BESS can reliably offset high-cost diesel generation in remote, grid-constrained operations.
Technical Brief
- Control logic prioritises solar utilisation while coordinating BESS charge–discharge to maintain baseload continuity.
- BESS integration reduces start–stop cycling of diesel gensets, lowering mechanical wear and maintenance interventions.
Our Take
Kamoa-Kakula’s move to a solar-baseload configuration with DHYBRID’s system comes as Ivanhoe Mines has twice cut 2027 copper output guidance and raised C1 cost guidance, suggesting that displacing about $11 million of diesel in a month is now material to keeping the operation competitive on unit costs.
Our database shows multiple recent Kamoa-Kakula items focused on throughput growth and novel comminution (e.g. the I-ROX pulsed-power work), so integrating large-scale BESS and controls into the power system also de-risks future high-energy process upgrades that would otherwise lean heavily on diesel or grid power in Africa.
