The proposed Silicon Valley Hub in Kolkata, the flagship information technology (IT) project of the West Bengal government, has attracted four major players — Reliance Jio, Tata Consultancy Services, Capgemini and Firstsource. The four companies are the major ones among others to have submitted proposals under the expression of interest (EOI) floated by the West Bengal government for setting up units in the proposed hub, said Amit Mitra. While Jio had sought 40 acres of land, TCS had sought 20 acres, Capgemini 10 acres and Firstsource 4 acres. The proposals of the four companies account for 75 per cent of 100 acre land in the hub. In view of the positive response, Chief Minister Mamata Banerjee has sanctioned another parcel of 100 acres of land under the project, said Mitra. Mitra said that TCS is planning to invest close to Rs 12 billion in Kolkata, and adding about 2.5 million square feet of space. It will add close to 17,000 new heads in its Kolkata campus, which would add to its existing workforce of 38,000 in the city, he said. The setting up of the Silicon Valley hub was formally announced in August, and the CM had also announced that Infosys was planning to set up a software development centre at the hub, with an investment of Rs 1 billion, which would generate 1,000 jobs in the first phase.
