alt Hacker NewsI want to know what Singapore's grid operators have been up to. That seems to be the more interesting story based on the data in this article.

Singapore is also a 730 km^2 island city-state with a population of about 6.2 million people. I have honestly no idea why people and articles keep comparing it to literally the largest countries on the planet both in terms of land area and population. Ask any other wealthy cosmopolitan world city of about the same area and population what their electricity reliability figures are, and the answers will probably be quite similar.
Inb4 (in this case in-after) trope answers (see below) like 'veneer of perfectly clean and orderly society', 'punitive'. It is small; that is why it can get stuff done.
Singapore is a very small city. Distribution losses are linear with distance!
It seems to be an investment in underground distribution structures and advanced monitoring including predictive failure analysis.
However there's kind of a funny part to it that I read on the last page of New Scientist some years ago. According to that story, Singapore has by far the lowest rate of accidental line cuts - it's a step change to almost zero from the next best country. Apparently there's a worldwide organization that meets to discuss these things. At one meeting the Singaporean engineers presentation was eagerly anticipated but as he was going through his points the engineers from other countries were impatient - they know and do all this! Until he got to his final point: accidental line cuts in Singapore result in 10-year prison sentence. Hence the difference.
