History and Development
Conception and Planning
The idea of creating a technology SEZ in Kolkata emerged in the mid‑2000s when the Government of West Bengal and the Ministry of Commerce & Industry sought to expand the state’s footprint in the IT sector. The DLF Group, with extensive experience in developing IT parks, was approached to spearhead the project.
Initial feasibility studies were conducted to assess land availability, infrastructure requirements, and market demand. The proposed site was identified in the South 24 Parganas district, approximately 20 kilometres south of the city centre, in an area earmarked for industrial development under the West Bengal Industrial Development Act.
Construction Phase
Groundbreaking took place in 2010, followed by a phased construction plan. The first phase focused on core infrastructure, including grid connections, water supply, and road access. Subsequent phases added high‑speed fiber corridors, secure data centres, and administrative buildings.
