Power Shortage in Hyderabad

Even though hyderabad is the capital of Andhra Pradesh, one point i really hate about it is the power shortage.
Now a days almost for about four hours in a day we are not having power. I see that lot of companies are coming to hyderabad like software,hardware and even fab city but why basic issue like power is not been considered is a big question.
we need to learn at least from other countries in this regard. the political leaders should have at least a minimum idea about when to add new power plants etc..
As far as i know i dont see any increase in power plants in AP from quite some time.
God only save AP.
