Adani Gates & Special Economic Zone Ltd, part of the Adani Group controlled by Gautam Adani, the second richest man in the world, has been selected to develop the deep-sea port of Tajpur in West Bengal, according to a statement from the state government. The greenfield project will entail a total investment of Rs 250 billion ($3.1 billion), of which Rs 150 billion will go to port development and the rest to build related infrastructure.

The latest project adds strength to India's largest private sector port operator, which already has a domestic market share of 30% and has won global contracts including the Haifa Port project in Israel and a port terminal in Sri Lanka. The Adani conglomerate has been scaling up existing businesses and rapidly entering new ones, such as cement, airports, the media and data centers.

The state government expects to create 25,000 direct jobs and more than 100,000 indirect jobs through this port, which is about 105 miles away from the state capital of Kolkata, according to the statement.

A wholly owned subsidiary of Adani Ports signed a pact last week to modernize a berth at Haldia Port in West Bengal.
