The article doesn't cover this, but, a huge contrast is Torrent Power (Ahmedabad/Surat), which has consistently (over many decades, the ahmedabad power company is actually over 100 yrs old) maintained world-highest levels of electricity supply and service quality, distribution losses, billing efficient. Beating Tokyo, equaling Singapore.

Zero load shedding, on-site within 10 minutes typically in case of fault reports, ALL supply lines underground. Planned maintenance schedules communicated week+ in advance (rare, once every few years).
