That is a good choice. In power sector, I am sure NHPC will do great in long term as it is based on natural reversible source unlike NTPC which is mostly coal based.
I have NHPC in my portfolio but I am planing to dispose it once Nifty crosses All time high(hope in profit). Because I feel N power would be more suitable for India due to merit of Npower Plant and demerit of Hydro Power Plant.
I think India will go on France Line and majority electricity would be generated with N Energy.
I will also Include a Distillery in my portfolio as it is going to be a BIG market.
Why do you want SBI and PNB both ? Sorry it is your portfolio but I thought I am missing some thing.
