State power utility Eskom will miss a target to boost output from struggling coal-fired plants by the end of March, highlighting the poor state of equipment whose viability is being reviewed by German energy consultants. Eskom Holdings, which is subjecting South Africa to its worst-ever electricity outages, told lawmakers in January it planned to increase production from six struggling facilities by 1,862 megawatts by the end of March. That would be enough to meet the needs of South Africa’s second-biggest city of Cape Town, where peak demand in winter is 1,800 megawatts.
