Tamil Nadu is set to augment its power generation capacity by 2,640 megawatts (MW) through a combination of thermal and green energy projects.
This ambitious plan aims to strengthen the state’s energy infrastructure, ensuring a stable and sustainable power supply for residential, industrial, and commercial sectors. Currently, Tamil Nadu’s total installed power capacity stands at 41,126.68 MW as of September 30, 2024, with renewable energy contributing significantly to this figure. The state’s energy roadmap focuses on enhancing both conventional thermal power plants and expanding its green energy portfolio, aligning with India’s broader goals for a low-carbon, sustainable future.
Key projects expected to commence commercial operations this year include the third stage of the North Chennai Thermal Power Station, adding 800 MW to the grid. Additionally, the first stage of the Udangudi Thermal Power Plant, with a capacity of 1,320 MW spread across two units, is scheduled to begin operations. In the renewable sector, the Kundah Pumped Storage Hydro Electric Power Project (500 MW) and the Kollimalai Hydro Electric Power Project (20 MW) are poised to play pivotal roles in diversifying the state’s energy mix. Officials from Tamil Nadu Power Generation Corporation (TNPGCL) and Tamil Nadu Green Energy Corporation (TNGECL) briefed the Tamil Nadu Electricity Regulatory Commission (TNERC) on the status of these projects. According to the officials, TNPGCL is exploring the use of washed coal to enhance the plant load factor (PLF) of its existing units, potentially increasing the efficiency of power generation from current levels of 500-600 MW. A trial run of this initiative is expected by the end of April, timed to meet the peak summer power demand.
Furthermore, the corporation has plans to install a flue gas desulfurisation system by June 2026. This technology aims to significantly reduce sulfur emissions from power plant smoke, contributing to improved air quality and environmental sustainability. TNERC has recommended the use of 400 kVA transmission lines to facilitate efficient power evacuation from these plants. The Udangudi Thermal Power Plant is also progressing steadily, with two of its units set to begin commercial operations in May and August. Infrastructure development at the site is advancing, with the completion of power evacuation networks, coal transportation logistics from the port, and critical installations such as pump houses, crusher houses, and cable-laying works.
In the renewable energy sector, TNGECL reported that the four units of the Kundah Pumped Storage Project are expected to be commissioned between July and November. The project, however, awaits forest clearance for the erection of transmission lines spanning 14 km. Efforts are underway to secure the necessary approvals to ensure timely completion. The Kollimalai Hydro Electric Power Project, which faced delays due to the COVID-19 pandemic and land acquisition disputes, is now projected to commence operations in October. The final phase of land acquisition is in progress, with the Namakkal district revenue department overseeing the process. To support the smooth transition of these projects from construction to operational phases, TNERC has recommended adequate manpower allocation for the operation and maintenance of the new plants. The regulatory body has also requested a detailed report on the status of all projects, including the steps taken to address any pending issues, by the end of this month.
This expansion aligns with Tamil Nadu’s vision of enhancing its energy security while promoting sustainable development. The integration of green energy projects reflects a growing commitment to reducing the carbon footprint, supporting India’s national climate goals, and fostering environmental stewardship. The state’s robust energy infrastructure not only supports its burgeoning population and industrial growth but also plays a crucial role in shaping a greener, more resilient future.
As Tamil Nadu continues to invest in both thermal and renewable energy, the state is poised to become a model for sustainable energy development in India.
