Adani Ports and Special Economic Zone (APSEZ) will invest INR300 billion (US$3.2 billion ) in developing Vizhinjam port, expanding its capacity from one million TEU to 5.7 million TEU by 2029, reports Chennai's Hindu daily.

APSEZ managing director Karan Adani said the investment includes INR16,000 under phase two. He described the project as the largest private investment in Kerala, positioning Vizhinjam as the biggest transshipment port in the Indian subcontinent.

Mr Adani told the inauguration ceremony that Vizhinjam will also be India's most technologically advanced port. He said it would serve as a model for how future Indian ports should operate.

He credited late Kerala Chief Minister Oommen Chandy for initiating the project and praised current Chief Minister Pinarayi Vijayan for sustaining momentum. Mr Adani said political clarity and long-term commitment were vital for large infrastructure projects.

He added that Mr Vijayan's consistent support had been central to turning Vizhinjam into a nationally and globally significant maritime hub. He called the Chief Minister the company's biggest asset in implementing such a large greenfield project.
