Stake sale in power producer NTPC Ltd. on Thursday is expected to raise around Rs 12,000 crore ($2.25bn), which will make it the government's largest share sale this financial year, according to disinvestment secretary Ravi Mathur.

An empowered group of ministers (EGoM) led by union finance minister P Chidambaram on Tuesday finalized the timeline and pricing of the issue.

After the EGoM meeting, the disinvestment secretary said, "The NTPC disinvestment is scheduled for February 7 and is expected to raise Rs 12,000 crore."

The minimum offer price, or the floor price, for the NTPC issue will be notified to the stock exchanges today, February 6.

According to people familiar with the matter said that the issue is likely to be priced at around Rs 147 to Rs150 a share, at a discount of around 5 per cent on Tuesday's closing price. The stock gained 0.16 per cent to close at Rs 155.60 on the Bombay Stock exchange (BSE) on Tuesday, but it lost 0.19 per cent on the National Stock Exchange (NSE) to close at Rs 155.25 apiece.

The government has plans to offload 9.5 per cent stake or sell 78.32 crore shares in the public sector power producer via the offer for sale route. Following the planned disinvestment, the government's holding in NTPC would come down from 84.50 per cent to 75 per cent.
