Petronas had offered $460 million for a 20% stake in NTPC Green Energy, outbidding local Indian firms with an offer of 27.52 rupees ($0.3362) per share, Reuters reported last month.
The source, who declined to be named as they were not authorised to speak to the media, said NTPC had been seeking an even higher valuation, but Petronas declined.
NTPC and Petronas did not immediately respond to requests for comment.
India's renewables sector is attracting increasing foreign
investment and was among the country's top five industries for
overseas funds last fiscal year, taking a 5% share of all
inflows from April to September 2022, against 3.3% in the same
period a year earlier.
Bloomberg News reported earlier on Thursday that Petronas
withdrew its earlier offer saying a 20% stake was too small and
would not give it a seat on the unit's board.
