SUPARCO bhai, why don't you install solar power in your house as a permanent solution to your woes? For a little over Rs 1 Lakh you can have uninterrupted electric supply in your house forever without depending on the grid. From a practical standpoint, it makes sense to make the switch over to solar power when the price of the system gives you electricity far cheaper than what you can get it from the grid for. Within 5 years your capital cost would be paid up after which you won't have to pay a dime for electricity, ever! No power cuts, no late payments of bills, no service tax, no yearly deposits!
I save 75% on electric bills! From cooking, to hot water for bathing/washing, lights, TV, etc - it's all solar power! Now why not 100%? that's because I live in a hill station where the weather sometimes throws a spanner in the works!! But still, 75% is a hell of a lot in savings!
Cheers!
