Earlier quoted context omitted.
We have it in South Africa too. The official, political term for it is "load shedding".
Nepal calls it load shedding too. In practice it's fairly counterproductive there. People buy banks of car batteries and inverters to store power when it's available and use it later. So they use as much power as before, with the added benefit of tons of hazardous waste from all the equipment at each building. Which of course they just throw into piles of broken stuff. Does the same happen in South Africa?
The pattern is simular, unstable supply leads to private infrastructure. Demand increases when supply is available, leading to more instablilty. Quality goes down because private infrastructure is usually second rate.
In egypt water quality is way down because of private storage in water tanks.
