What Is Causing South Africa’s Ongoing Electricity Crisis?

For many South Africans, load shedding is the defining feature of the country’s electricity problems. But the country’s electricity crisis didn’t begin with load shedding. Instead, it is simply the visible symptom of a power system that has been operated beyond its limits for years.
The deeper story is structural. Historically, South Africa built an electricity system that leaned heavily on large coal-fired power stations. Over time, the country has struggled to maintain them, replace them, and modernise the grid at the pace required to keep the system reliable. Political instability and other crises have compounded these challenges.

The result has been a cycle of breakdowns, deferred maintenance, procurement delays, and constrained transmission, all reinforcing one another. Recent analysis by FTI Consulting highlights that unplanned outages and tight operating margins have largely driven the frequency and severity of load shedding. Sudden surges in electricity demand did not cause it.
>Data released by the country’s Government-controlled Electricity Supply Commission (ESCOM, known as ESKOM) shows that load shedding can ease when plant performance and overall system conditions improve. However, these gains are fragile. As long as the system remains dependent on a small number of ageing assets, with limited reserve capacity, underlying vulnerabilities persist.
