South Africa's problem is the ANC stopped Eskom building what it needed with foreseen growth when they came into power in the 90s. They wanted to introduce competition into the generation market.
They didn't introduce competition, as you might expect from a hyper-incompetent government, and just let the issue languish, and South Africa now just doesn't have enough power plants to serve its population when it takes one offline for scheduled maintenance.
But at least a lot more people got to buy Audis with the freed-up money sloshing around.
