Eskom's Failure to Inform the Public on Stage 8 Load Shedding

Eskom, South Africa’s state-owned power utility, has been accused of keeping the public in the dark about the severity of the country’s rolling blackouts. While Eskom has stated that the blackouts have only reached Stage 6, reports indicate that the situation is far worse. According to The Daily Investor, Eskom’s rolling blackouts reached 7,072 MW on April 13, which corresponds to Stage 8 according to Eskom’s definitions. If Koeberg’s Unit 2, the last operational unit at the nuclear power plant, is not brought back online, power outages could last up to six hours.

Despite the gravity of the situation, both Eskom and Electricity Minister Kgosientsho Ramokgopa have been deafeningly quiet about reports that South Africa has been plunged into Stage 8 rolling blackouts. Ramokgopa had previously warned that Eskom would face a shortfall of 8,000 MW to 10,000 MW this winter, resulting in Stage 10 power outages. Since April 12, the country has been in Stage 6, and Eskom has stated that this will continue “until further notice.” There are currently no functioning units at Koeberg.

Daphne Mokwena, an Eskom spokesperson, denied that Stage 8 load shedding was implemented, stating that on the day in question, Eskom load-shed at Stage 6, 5,719 MW, and also called for Stage 4 load curtailment of 1,353 MW from participating customers who responded by reducing their own load. Mokwena did, however, admit that the load that was reduced was in fact greater than 6,000 MW, which is equivalent to Stage 8 power cuts. She explained that Eskom avoids using this terminology because the public becomes confused and believes they are discussing load reduction, which is normally used when load-shedding is not in effect to prevent equipment failure due to overload.

This is not the first time the country has been subjected to blackouts that go beyond Stage 6. Sikhonathi Mantshantsha, then-Eskom spokesperson, stated in February that the power utility was shedding 7,045 MW of electricity without announcing that it had progressed beyond Stage 6. The situation has been exacerbated by the loss of four major units, which have been on extended outages, as well as the unavailability of three units at Kusile and one at Koeberg 1, which have removed 3,080 MW of capacity from the grid.

Dr Zwanani Mathe, CEO of the South African National Energy Development Institute, has expressed concern about Eskom’s recent reporting on load shedding stages. Mathe stated that the situation would worsen if Koeberg Unit 2 did not return to service soon or if another large unit trip occurred. He anticipated that Eskom or the electricity minister would brief the country on the situation.

Eskom’s lack of transparency is concerning because it has a significant impact on South Africans’ daily lives. It makes it difficult for individuals and businesses to plan for and prepare for prolonged blackouts, which can last up to six hours or more. It also emphasises the importance of increasing investment in alternative energy sources in order to reduce reliance on Eskom’s coal-powered plants, which are plagued by maintenance issues and breakdowns. The current situation highlights the critical need for South Africa to develop a more reliable and sustainable energy system.
