[The Conversation Africa] Since late last year South Africans have, once again, been subjected to power cuts by the power utility, Eskom. The need for what's called loadshedding - planned power outages - led to the recent resignation of Eskom's chairperson and a flurry of concern about the current and future reliability of electricity supply. It has also raised questions about the lack of progress in resolving Eskom's financial and operational crises since Cyril Ramaphosa became the country's president in early 2018.
