"NTPC's follow-on public offer and NHPC's initial public offer will come when the market conditions are conducive," Power Secretary Anil Razdan said.
NHPC had earlier scheduled the launch of the offer between October 13 and 17 to raise nearly Rs 1,670 crore (Rs 16.70 billion) worth fresh equity, besides premium.
Last year, the company had to shelve its initial plans as the requisite number of independent directors were not on the Board and now due to the choppy market conditions.
