load shedding happens in Maryland, USA every year during peak summertime. it's usually just for a couple hours each day.
slightly different situation and more in line with Eskom's wonderful "wet coals" claim
Power utilities around the world have the challenge of managing different demands of customers with respect to reliability, quantity and price and the disconnects that occur between capacity (which is supplied) and consumption form (which is demanded) is always a problem. In proper systems you can trade reliability for price and "spare capacity" is sold on to customers who need to shut down usage when there isn't spare capacity for a lower price (which should be reinvested) but you cannot have a situation where heavy industrial users are receiving a public subsidy as is the case in SA. Now the subsidy of course is because of the crony socialism of the ANC (and the ANCs particular flavour of cronyism, psuedo-socialism, peri-communism, inept totalitarianism and liberal human rights is a special discussion)

And then remember that Eskom buys coal from the large energy users and these contracts are also problematic - if the coal mine can't get you the needed quantity of sufficient grade coke you need to cut them off rather than give them cheaper electricity than everybody else.
but Eskom is like an addict - they will do anything for their coke dealers, even sign stupid contracts
Maryland has an energy sector that requires loadshedding during the summer to preserve the pricing that is prevalent, General Motors has had furlough mechanism that kicks in when there is an electricity strain causing the discounted pricing to be unavailable, many rail networks
We have a situation in South Africa where some energy users who are very low down the list for blackouts consume an inordinate amount of electricity relative to everybody else at a lower price than what the majority of users are paying. Our electricity price at consumption point is incredibly high due to a deadweight in the economy that is municipal taxation (the monopoly resale point) when compared to the tariff allowed for generation
Basically electricity is sold against a user pay principle with electricity funding those lovely potholes in local roads. To accommodate some of these users base load requirements Eskom have invested in energy generating capabilities that are more expensive than the tariff they get - fueling the financial crisis: while it isn't the farmers fault the Western Cape agricultural requirements are not helping the situation by virtue of getting electricity at an uneconomic (from Eskom's perspective) price.
What needs to happen to resolve our electricity crisis includes:
[1] The discrepancy between the price at point of consumption (what households pay) and the point of plant (what the power producer receives) needs to narrow significantly (NERSA can give Eskom what they want at the expense of the municipalities but watch other cards fall)
[2] Transmission needs to be separated from plant, the horse**** we have in Jbay where transmission capacity is lacking as against generation coming on stream. [REDS is a political crisis]
[3] The feed in tariffs and independent power producers political nonsense needs to end.
[4] New large power facilities (nuclear in particular) need to be outside of Eskom's control
[5] Eskom needs to SPV and sell off individual plants who sell into transmission - with Eskom's separated transmission becoming Eskom: the Electricity Supply Commission (electricity generation in this country started as a private sector venture which was eventually poorly nationalized)
[6] Eventually an energy exchange and so forth need to come on stream
the TL;DR version:
Its not loadshedding we should be bitching about but rather Eskom's coke addiction and the fact that they will pay their coke dealers above everybody else
