In 2008, the IPO of a power company got subscribed in less than a minute of its opening and the size of that issue was Rs 11,563 crore. This just shows the desire to own power sector stocks at that point of time. From those days of frenzy to the nadir in 2014, when power companies were on the top of the list of NPA of the banks. Power companies have seen both the extreme of valuations. It is a sector where after many failures and to some extent a consolidation, some companies have emerged which know how to deal with all kinds of economic and industry cycles. That is probably the reason why a number of companies from the power sector have seen a sharp re-rating in the last one year. Hoping the survivors have learnt their lessons.
