In India electricity is provided by different organisations hence rate is not fixed for whole country , but the rural and undeveloped areas get subsidy mining in such areas is quiet profitable.
Any particular area where you know the electricity rates? Also, do you know if that area has power outage problems? Usually rural areas in india has power outage for 30% of the times n a day.. .Some parts of punjab still has outage of 4 hours every day... That will eat up all the profit and the damage to hardware when turned off directly without shutting down
