Ivanhoe Mines has launched a tender for a 10-MW solar power plant with battery storage to supply its Kipushi zinc mine in the Democratic Republic of Congo, the company said in its first-quarter 2026 financial report published May 6.
The facility is intended to provide stable baseload power, supported by storage capacity of up to 200 MWh over 24 hours. The project will be built on a 70-hectare site near the mine and developed, owned and operated by a third-party partner under a take-or-pay agreement. Commissioning is expected in late 2027.
The project comes as Kipushi continues to face unstable electricity supply. In its financial report published Aug. 27, 2025, Ivanhoe said it was strengthening backup capacity by installing an additional 6 MW of generators to support operations during periods of grid instability.
In annual results released Jan. 15, 2026, the company said it had further expanded backup generation capacity at Kipushi during the fourth quarter of 2025 to reduce disruptions linked to instability on the Congolese power grid.
Despite those measures, Ivanhoe acknowledged in its first-quarter 2026 report that grid instability continued to disrupt concentrator operations. The company said it had increased backup generator capacity at the site by 20%, bringing total installed backup capacity to 20 MW.
Separately, upgrades to Kipushi’s 120-kV electricity substation were completed and commissioned at the end of the first quarter of 2026. According to Ivanhoe, the upgrades should improve management of grid fluctuations and help protect strategic infrastructure, including the concentrator.
Production ramp-up
The solar project is intended to reduce reliance on diesel backup generators, which are currently used intermittently.
At the same time, Kipushi is undergoing a rapid production ramp-up. According to operational results published Jan. 15, 2026, the zinc mine — owned 62% by Ivanhoe Mines and 38% by Gécamines — quadrupled output in 2025 to 203,168 tonnes of zinc concentrate, from 50,307 tonnes in 2024.
The increase followed engineering work launched in September 2024 to expand concentrator processing capacity by 20%. The optimization program was completed in early August 2025.
Production growth continued into the first quarter of 2026. Ivanhoe said Kipushi produced 65,044 tonnes of zinc in concentrate during the first three months of the year, compared with 42,736 tonnes a year earlier. Sales reached 54,940 tonnes of zinc, up from 30,108 tonnes in the first quarter of 2025, at an average realized price of $1.47 per pound.
For 2026, the company is targeting production of between 240,000 and 290,000 tonnes of concentrate. With output rising, securing reliable electricity supply has become critical to stabilizing operations and sustaining the mine’s expansion.
The energy strategy forms part of broader investments by Ivanhoe in the DRC. At Kamoa Copper — a joint venture between Ivanhoe Mines, Zijin Mining Group, Crystal River Global Limited and the Congolese state — a 60-MW solar plant is under construction near Kolwezi. The company has also started signing contracts for a second phase of the program, which aims to increase total solar capacity to 120 MW.
