Several mining companies in South Africa have had to temporarily shut down domestic operations after receiving requests by Eskom to reduce their load on the national power system. This comes after Eskom instituted stage 6 load-shedding for the first time on Monday evening. Stage 6 was downgraded to stage 4, which the power utility expects to continue until 11pm. The Minerals Council of South Africa, which represents 90% of the companies in South Africa’s industry, confirmed to Fin24 on Tuesday that all of its member mines had been alerted by Eskom to reduce their loads by 20%.
