Zambian copper mines desperate for power find an unlikely saviour

Zambia’s biggest mines are turning to a surprising power source as the copper-producing nation battles an unprecedented energy crisis: South African electricity company Eskom Holdings, which until March faced its own severe deficit. An historic drought has stifled hydropower turbines that Zambia relies on for about 85% of supplies. Households have power for just three hours a day. And firms like First Quantum Minerals have had to look beyond the nation’s borders for electricity to keep their mines and smelters running.
