i'm doing some design work for a 3rd world country. power infrastructure in these countries is limited. remember that many of these countries have not even had stable governments, let alone the infrastructure required to keep services in working order. whether the infrastructure is government owned or privately owned doesn't really matter, it's difficult to keep things working in a politically unstable environment. infrastructure also takes money to maintain, and many countries don't have the money to properly maintain what infrastructure they do have...
here in the US it took 30 years or more to get every house on the grid, up until 1968 or so, there were still AC-DC powered appliances being produced, and the Rural Electrification project began in the 1930's.
in the project i'm working on, i have to add solar and battery power options to the equipment that normally runs from a power line. not an easy task, but fortunately there are a lot more devices today that can do the job.
