Can we avoid massive power blackouts in India?

Two power blackouts in the North and Eastern parts of the country on 31st July and 1st August 2012 have thrown up many issues to our society. The second blackout impacting three regions (Northern, Eastern and North Eastern regions) and covering 21 states was preceded by another blackout the previous day impacting fewer states in the northern region. The media have reported that about 600 Million people were affected by the larger blackout. Many sections of the media have termed this blackout as the most sever blackout in the history; certainly it can be termed as one of the severest power outage events in independent India.
