The share sale through an offer for sale (OFS) will happen over two days beginning tomorrow, an official said here.
NTPC shares closed 2.5 per cent higher on the BSE at Rs 173.55 apiece today.
The official said the government will sell 5 per cent through OFS, with an option to retain another 5 per cent in case of over-subscription.
The floor price of Rs 168 is at a discount of 3 per cent over today's closing stock price.
This is against Rs 72,500 crore targeted to be raised in 2017-18 through stake sale in PSUs.
This includes Rs 46,500 crore from minority stake sale, Rs 15,000 crore from strategic disinvestment and Rs 11,000 crore from the listing of PSU insurance companies.
