NTPC programmes are in collaboration with iim ahmedabad faculty.
and 24 month programme is exclusively meant for energy sector.with electives- for in house and pvt sector requirements.
energy sector- would consist of renewable sources-like wind, tidal waves, hydro, thermal power and nuclear power.
it is a premier programme and my opinion is the passouts will not have problems in placements with eminent faculty and great sponsor .
So, it's upto youu which school you want to go.
