Pretty sure you mentioned SC/ST somewhere in the discussion above and later deleted the post, but I'm here to enlighten you about how and why you will miserably fail with your attempts at achieving this 'free electricity' gimmick.
Firstly, living in a metropolitan city, I can assure you everyone pays the same electricity bills depending on the units consumed, irrespective of caste. You're probably exploiting a loophole around the system as this is the system is followed throughout the country as far as I know.
What you're probably doing is falsely claiming to be either SC/ST by providing fake documents but even if you manage to pull this off, don't expect your mining farm to last long as sleuths will catch you one way or the other.

I am saying its more than like free here. 2.5$ is not an amount which you can compare. And Its not illegal. I was referring to the companies where they always pays the bills but you can use the electricity as much as you want. There is nothing illegal.
What's the $2.5 nominal cost here? Looks like an attempt to bribe your local power officer to keep to let you continue with your shady activities without being caught. Let me tell you, any attempts of this sort can get you behind bars.
