Those places generally have the luxury of 24/7 electricity, normally via diesel gensets, for key parts of their infrastructure, such as fuel transfer, hospital, food supply.

The places that don't have the fallback ready access to fallback diesel genset, like rural South Sudan or Burundi, are pretty close to an end of the world scenario.

Don't romanticise disaster. If a developed country indefinitely lost power, a huge swathe of the population would die, starting with the infants, elderly, and chronically ill. Then hunger and disease would come for the rest. Nonsense ideas that we'd MacGyver or bushcraft our way out of trouble are infantile.
