The feed of hydroelectric power, from Inga II to Kamoa Kakula, is expected to increase to 100 MW in 1Q26 and then increase to 150 MW as grid improvements are completed. Installation of replacement mechanical and electrical equipment at Turbine #5 at the Inga II hydroelectric facility was completed in 3Q25, followed by synchronisation and energisation of Turbine #5 in early 4Q25. The newly refurbished Turbine #5 has since ramped up to full capacity, delivering approximately 180 MW of clean, hydroelectric power into the DRC grid. Of the 180 MW being delivered into the grid, Kamoa-Kakula is currently receiving an initial 50 MW, bringing its total domestically sourced power to approximately 110 MW.
Hydroelectric power delivery to Kamoa-Kakula, from Turbine #5, is expected to increase to 100 MW in Q126 and to 150 MW thereafter as grid upgrades are completed. The grid improvement initiatives primarily focus on upgrades to substations at Inga (SCI) and Kolwezi (SCK). The first upgrade, consisting of resistor banks at the Inga substation, was completed in May 2025. Corresponding resistor upgrades at the Kolwezi substation are expected to be completed imminently, improving voltage stability to Kamoa-Kakula. In addition, the static compensator at the Kolwezi substation is scheduled to be completed in early 1Q26, increasing the power delivery from Inga II to the Kamoa-Kakula up to 100 MW. The remaining workstreams to upgrade the filter banks at SCI and SCK will occur in phases over the next 18 months, ultimately increasing the total power received from Turbine #5 to 150 MW during 1H27. By the end of 2027, total domestically-sourced, renewable grid-supplied power is expected to be approximately 210 MW.
