The issue is that electricity in Mumbai isn't reliable, whereas electricity in Ganzhou is...
What's unreliable is the currency of your opinion.
There hasn't been load-shedding in Mumbai for years.
lol? Still can't own up to the fact that your "financial center" has blackouts every other week?
The last "blackout", my self-serving comrade, was due to a BEST transformer bust for a total of two hours in a total of 2 sq.km. of South Mumbai in Nov 2012.
There has been no "blackout" other than that in recent memory. Just as load-shedding, which is the real gauge of reliability and efficacy of power distribution, has been consigned to the past.
