South Africa’s Power Crisis: How Eskom’s Load Shedding Affects Millions

The causes and impacts of the state-owned utility’s power cuts

by Motoni Olodun

South Africa’s state-owned power utility, Eskom, has announced that it will reduce the intensity of load shedding from stage 6 to stage 5 on Sunday from noon. This comes after two days of severe power cuts that plunged millions of households and businesses into darkness and disrupted essential services.

Load shedding is a measure that Eskom uses to prevent a total collapse of the power grid by rotating power outages across different areas. The stages of load shedding range from 1 to 8, with higher stages indicating more severe and frequent power cuts.

According to Eskom, stage 5 load shedding entails a significant reduction in electricity supply, with consumers expected to endure prolonged periods without power. However, Eskom assured the public that it actively monitors the power system and provides timely updates regarding any changes to the load-shedding schedule.

The reason for the drastic escalation to stage 6 load shedding on Saturday was the failure of nine generating units due to boiler tube leaks, which resulted in a loss of 4,400 megawatts of generating capacity. Eskom said that its teams were working diligently to restore the units and replenish the pumped storage dams, which are required to meet the morning and evening peak loads.

Eskom’s power crisis has been a long-standing issue that has plagued South Africa for over a decade. The utility faces multiple challenges, such as aging infrastructure, inadequate maintenance, coal shortages, corruption, mismanagement, and debt. Despite receiving several bailouts from the government, Eskom remains financially and operationally unsustainable.

The impact of load shedding on the South African economy and society is immense. According to a report by the Council for Scientific and Industrial Research (CSIR), load shedding cost the country an estimated R75 billion in 2020. The report also found that load shedding reduced the country’s gross domestic product (GDP) by 0.5% and increased unemployment by 0.1%.

Load shedding also affects the quality of life of millions of South Africans, who have to cope with disruptions to their daily activities, such as work, education, health, and entertainment. Many people rely on alternative sources of power, such as generators, solar panels, batteries, and candles, which can be costly and unsafe. Load shedding also poses a threat to the security and safety of communities, as it increases the risk of crime, accidents, and fires.

The South African government has acknowledged the urgency of addressing Eskom’s challenges and has announced several interventions, such as the unbundling of Eskom into three separate entities, the procurement of additional power from independent power producers, and the implementation of the Integrated Resource Plan, which outlines the country’s energy mix for the next decade.

However, these interventions are likely to take time to yield results, and in the meantime, South Africans will have to brace themselves for more load shedding in the foreseeable future. Eskom has warned that the power system remains vulnerable and unpredictable, and that load shedding is a reality that the country will have to live with for at least another five years.
