I worked for a time on the Falklands, job wise power 24/7 so as UK, but on the camp (countryside) farms only had power so many hours a day, two slots, a morning one to bring freezers down to temperature and allow use of vacuum cleaner etc. Evening slot again to bring freezer down to temperature and get rid of need for candles which it seems had caused many a house fire.
Smaller farms had auto start generators, that would start when anything switched on, but there was a problem going to toilet at night, so battery banks, and DC lighting was used.
This was 1985 to 1990 no mobile phones, even wired phones were single wire and did not work in wind, or where wires had broken inside the mine field, all coms was really 2 meter ham radio, and these also needed batteries to work.
I am sure now they have phones and even internet, but it was a different world where there was no 24/7 230 volt power.
