Electricity Minister Kgosientsho Ramokgopa was outspoken before the cold weather hit the southern African country: “I’ll be brutally honest, the winter will be incredibly tough. » That was counting without the El Nino weather phenomenon. According to energy experts, electricity demand since the start of the southern winter in June has been less than feared due to abnormally high temperatures for the period.
An increase in tariffs has also pushed companies to consume reasonably, according to specialist Tshepo Kgadima. “Even at the height of winter, demand at peak consumption is around 30,000 megawatts, instead of the planned 37,000 megawatts” by the government, he told AFP. Experts even predict a drop to 25,000 MW in the near future, while the energy crisis had only worsened since last year. The public electricity company, Eskom, unable to produce enough, had in recent months imposed record cuts.
Production up
The secretary general of the African National Congress (ANC, the ruling party), Fikile Mbalula, on Wednesday hailed a “turnaround”ensuring that the “recovery” of Eskom will save the country “devastating socio-economic effects linked to the shortage of energy”. A crucial issue less than a year from general elections where the ANC risks, for the first time in its history, losing its majority.
At the same time, the country produced more electricity. Eskom said at the end of June it had achieved an average productivity of 60% at its plants, which are mainly coal-fired. “Production is starting to follow demand. That’s why we’re starting to see that for certain times of the day, regarding two-thirds, we don’t have load shedding, we’re starting to balance it out”welcomed last weekend Mr. Ramokgopa.

This additional available energy is however partly produced by independent groups from which Eskom buys the production. “at exorbitant prices”, more than five times higher than the cost in its power plants, underlines Mr. Kgadima. Eskom’s production is also dependent on diesel, the price of which is constantly rising: to fill the supply gap, the company relies on emergency gas turbines that burn 14 liters of diesel per second, or 50 400 liters per hour. The company has planned an annual budget of nearly 1.5 billion euros just for the purchase of diesel.
A colossal debt
Production also benefited from a mechanical effect: traditionally during the winter, anticipating a strong surge in demand, Eskom slows down maintenance operations on the country’s fourteen power stations. This year, the company kept a maximum number of units in service, reducing maintenance to 7% of the total fleet capacity, compared to an average of 13% in summer. “There is a very significant risk in not maintaining maintenance” power plants,” says energy expert Lungile Mashele. Eskom also announced, on Tuesday July 4, the resumption of load shedding during the day due to a “increased production unit failures”.
The looting of public coffers during the presidency of Jacob Zuma (2009-2018) and the lack of maintenance of power plants, whose average age today is 35, are among the main causes cited for the crisis. electricity in South Africa. According to former Eskom CEO Andre de Ruyter, corruption costs the company $55 million a month.

After his appointment at the end of 2019, the 55-year-old businessman suspended several senior officials for “misconduct” or “lack of results” and managed to partially reduce the colossal debt of the company, equivalent today to 23 billion. dollars that the government is trying to mop up. But “as long as there is no additional production capacity, there will be an inherent risk of load shedding”has repeatedly preached the CEO, who resigned in December.
