Accor plans to open 45 new hotels in 15 Indian cities over the next three years.
The Paris-based chain, which already has five properties on the sub-continent, said the expansion would include its Sofitel, Ibis, Novotel, Mercure and Pullman brands.
The expansion plans comes a week after the group reported a net loss of €150m for the first half of the year and the decision by its board to order a review of splitting up its hotel and services operations.
The first of the new hotels, an Ibis, is due to open next month in Pune.
The group said it had already committed $130m to its expansion in the Asian country.
Accor said three new hotels, an Ibis, Novotel and Pullman would open in Aerocity, the "hospitality" district at Delhi international Airport.
The expansion will also include the first Sofitel, Accor's five-star brand, in India.
This is due to open in Mumbai next year.
The plan will also see five new Novotels, on top of the existing three, and 15 new Ibises, including the one at Pune.
Accor said it expected to open seven new hotels in India in 2010, 18 in 2011 and 19 in 2012.
When the new hotels are all open, Accor will have 10,000 rooms in the country.
Michael Issenberg, Accor Asia Pacific's chairman and chief operating officer, said: "India is one of the world's most dynamic economies and a country that offers significant prospects for the development of hotels.
"Accor has developed an expansion strategy, created relevant joint ventures and investment commitments to ensure that Accor will be the leading international hotel operator in India by 2012."
Among the new properties, Accor will manage four hotels in India's new hill city at Lavasa: a Pullman with 258 rooms, a Novotel (200), a Mercure (130) and a Grand Mercure with 88 apartments.
The properties will also have meetings space for 1,500 delegates and complement the Lavasa Lakes Convention Centre.
Among other cities where hotels will be opened are Kolkata, Gurgaon and Bangalore.
Uttam Dave, president and ceo of InterGlobe Hotels,Accor's key partner in India, andhead of development for Accor hotels in India, said: "Acquisition of sites for the expansion of the ibis network continues and is ahead of our development forecasts.
"By early 2010 there will be three Ibis hotels operating in the key cities of Gurgaon, Mumbai and Pune, with seven more ibis hotels being completed by the end of 2011, providing the basis of what will become India's foremost international economy hotel brand."
