TN to Invest ₹15,312 Crore in Power Grid Reforms, Partners With IIT Madras
Following the release of the state government's White Paper on the power sector, the administration has outlined an immediate investment of ₹15,312 crore to strengthen transmission and distribution networks, alongside an ₹8,318 crore programme to modernise legacy assets. Speaking on the reform agenda, J Radhakrishnan, CMD of Tamil Nadu Power Distribution Corporation Limited (TNPDCL) and additional chief secretary to the Tamil Nadu government, highlighted key initiatives, including a recently signed memorandum of understanding with IIT Madras to promote translational research and adopt innovative engineering solutions.
The immediate planned investment of approximately ₹15,312 crore will focus on improving operational performance, financial sustainability, and infrastructure modernization. This funding will cover the completion of 121 ongoing substations, the establishment of 231 new substations, the augmentation of transformers and transmission lines, the reinforcement of the distribution network, and the procurement of critical equipment.
Additionally, the ₹8,318 crore programme dedicated to modernising legacy assets is designed to improve grid resilience and reliability. According to Radhakrishnan, the administration's priorities include optimising power procurement, enhancing asset utilisation, strengthening revenue collection, and reducing technical and commercial losses. The ultimate goal is to ensure that every investment results in measurable improvements in reliability and consumer service.
To optimize costs, TNPDCL is modifying its power procurement strategy. The utility intends to reduce its dependence on short-term, term-ahead, day-ahead, real-time, and power exchange purchases, which currently cost around ₹8.91 per unit. By increasing procurement through long-term and medium-term arrangements, renewable round-the-clock power, firm and dispatchable renewable energy, and storage-backed resources at an average of ₹6.63 per unit, the state expects to generate savings of nearly ₹215 crore per month during the summer.
These developments follow the 2024 restructuring of the power sector, which created dedicated companies for distribution (TNPDCL), generation (TNPGCL), transmission (TANTRANSCO), and green energy (TNGECL). This unbundling aims to improve functional accountability, operational focus, and performance monitoring across the state's power network.
