Load shedding costs the South African economy an estimated R900 million per day during Stage 6, according to the South African Reserve Bank. Over a full year of sustained high-stage load shedding, that's approaching R300 billion in lost economic output.
To put that in context — that's larger than the annual GDP of many African countries.
Large businesses have generators. Small businesses — spaza shops, hair salons, township restaurants — often can't afford them. Every hour of load shedding is an hour of lost revenue with no recourse.
The National Treasury estimates that small and medium enterprises bear 40–60% of the economic damage from load shedding, despite representing a smaller share of overall GDP.
Cold chain failures during extended outages spoil food at every point from farm to table. The Agricultural Business Chamber estimated losses of over R50 billion to the agricultural sector in a single heavy load shedding year.
South African manufacturing has contracted significantly since load shedding intensified. Companies that can relocate production have done so — Zambia and Mozambique have both attracted SA manufacturing investment specifically because of more reliable power.
Foreign direct investment (FDI) into South Africa has been materially affected. In surveys of multinational companies, load shedding is consistently cited as the primary barrier to investment decisions — above crime, regulatory complexity, and labour issues.
Several large investments have been delayed or cancelled specifically due to energy risk.
One unexpected shift: South Africans have become extraordinarily creative about working through outages. Inverter and solar adoption has skyrocketed. Load shedding has — ironically — accelerated South Africa's adoption of renewable energy at the household and small business level faster than almost anywhere else in the world.
South Africans working remotely for global employers are also somewhat insulated — a laptop and mobile data means they can work from a coffee shop, library, or anywhere with power during their scheduled outage window.
Eskom's generation capacity has shown genuine improvement through 2025, with load shedding frequency and intensity both declining from the 2023 peaks. The addition of independent power producers (IPPs) and the massive household solar adoption is structurally changing SA's power landscape.
The question is whether improvement is fast enough to recover the investment and growth lost during the crisis years.
