The Adani Group, which is setting up the world´s largest solar park in Ramanathapuram district, has expressed its willingness to invest in mining, ports and thermal power sectors in Tamil Nadu. Gautam Adani, Chairman of Adani Group, and Rajesh Adani, Managing Director of the group, called on Chief Minister J Jayalalithaa at the Secretariat in this connection. Sources said that during the meeting, the top brass of the Adani Group have made known their desire to invest more in the state. However, no specifics were discussed at the meeting because it primarily was a courtesy call. Both Gautam and Rajesh also conveyed their intention to expand the Kattupalli Port into a major port to compete with the Krishnapatnam Port in Andhra Pradesh. As far as Kattupalli Port is concerned, in November last year, the Adani Ports and Special Economic Zone, the biggest port operator in the country, reached an agreement to acquire this minor port complex built by Larsen and Toubro Limited.
