Adani Green Energy (ADNA.NS), opens new tab, the renewable energy arm of the group, will spend 340 billion rupees to add 6 gigawatts of capacity, Singh told reporters at a media briefing in Ahmedabad in Gujarat state.
The comments came a day after billionaire owner Gautam Adani told investors the group is "well positioned" to capitalize on opportunities in the country's booming infrastructure sector.
The group, which has businesses across ports, power utilities, transmission and coal trading, is betting on infrastructure spending, which is expected to grow at a compounded annual growth rate of 20%-25%, Adani said on Monday.
On Tuesday, Singh denied reports the group is planning to take a stake in payments firm Paytm (PAYT.NS), opens new tab, but said it will "evaluate any opportunities" in the fintech space.
