Larsen & Toubro (L&T) has committed to invest Rs 186 billion (bn) in Tamil Nadu across data centres, electronics manufacturing and shipbuilding infrastructure, marking the first major industrial investment pact since the government led by Chief Minister C. Joseph Vijay took office. The memorandum of understanding was signed at the Secretariat by L&T chairman S. N. Subrahmanyan and the chief minister, with the industries minister, the chief secretary, the industries secretary, and guidance executive director among officials present. The package is described by officials as a strategic engagement to bolster industrial capacity and attract technology and maritime investment.

The investments are expected to generate 8,200 jobs in the state and are structured across three projects. The largest element is a Rs 150 billion (bn) expansion of L&T's data centre business in Kancheepuram district, designed to support growing demand for cloud services, artificial intelligence and data storage infrastructure. Officials framed the project as a response to rising demand for digital infrastructure from domestic and global clients.

L&T will invest Rs 25 bn in an electronics and electronic systems manufacturing facility in Coimbatore, which is projected to create 2,000 jobs and to strengthen the state's manufacturing base in high-technology components. A further Rs 11 bn will be directed to the expansion of the shipbuilding complex at Kattupalli in Tiruvallur district, with the additional capacity expected to generate 5,700 jobs. The Kattupalli expansion is intended to reinforce Tamil Nadu's role in the offshore wind supply chain through enhanced fabrication and maritime infrastructure.

State authorities indicated that the investments align with broader plans to expand the economy to $1.5 trillion (tn) by 2036 through industrial growth, infrastructure development and employment generation. The projects are presented as complementary contributions to the state industrial ecosystem, linking digital, electronics and maritime capabilities. Officials said the MoU sets the stage for detailed project agreements and implementation schedules to follow.
