"TNPGCL is accelerating the development of two thermal power plants to ensure energy security during the peak summer months."

Tamil Nadu Power Generation Corporation Limited (TNPGCL) has stepped up efforts to commission two major thermal power projects as the state prepares for a surge in electricity demand during the summer months.

Coal synchronisation at the 660 MW Udankudi thermal power plant is expected to be completed by the end of January. At the same time, work is being expedited to ensure that the 800 MW North Chennai Super Critical Thermal Power Station (NCTPS) Stage III operates at full capacity from Friday.

TNPGCL Managing Director M. Govindrao said the two projects will play a crucial role in strengthening Tamil Nadu’s power supply during the peak summer season and reducing reliance on electricity purchases from private generators.

On the Udankudi project, Govindrao said the first unit is ready for power generation. “Oil synchronisation with the state grid was completed in September last year, and during trial runs the unit generated around 80 MW. We are now preparing for coal synchronisation,” he said.

He added that key infrastructure, including the coal jetty and pipe conveyor system, has been completed. For the purpose of coal synchronisation, coal is being temporarily transported from the Thoothukudi thermal power plant.

Referring to the long-pending NCTPS Stage III, Govindrao said the state’s first 800 MW supercritical thermal unit has recorded steady progress since its inauguration on March 7, 2024. “Since inauguration, the plant has generated 2,905.4 million units of electricity,” he said.

Although both plants have completed trial runs and generated power, the commercial operation date (COD) has not yet been declared. Govindrao said detailed technical checks are mandatory before COD can be announced to ensure all systems are functioning reliably.
