This summer, the Tamil Nadu Power Distribution Corporation Ltd (TNPDCL) has secured a significant new power source to address the anticipated surge in electricity demand across the state. The 800-megawatt Stage III North Chennai Thermal Power Station (NCTPS) has officially been declared fit for commercial operations, marking a crucial development for the region's energy infrastructure.
Meeting Chennai's Growing Power Needs
During the peak summer months, Chennai's power demand is projected to cross the 4,000MW threshold. With the new plant now operational, the city can rely on an assured generation capacity of up to 800MW from this facility alone. Previously, Chennai's electricity requirements were primarily met by NCTPS Stage I (630MW) and Stage II (1,200MW), with the remaining needs fulfilled through more expensive power purchases and central allocations.
Statewide Power Demand Projections
The entire state of Tamil Nadu is bracing for substantial electricity consumption this summer, with overall demand expected to exceed 22,000MW. The addition of the 800MW plant comes at a critical time to help manage this increased load.
Expanding Thermal Power Capacity
With the commissioning of NCTPS Stage III, Tamil Nadu's thermal power capacity has now increased to 5,120MW. This supercritical coal power plant, constructed on 190 acres of land in Athipattu within Tiruvallur district, represents a substantial investment of approximately 10,158 crore rupees.
Overcoming Operational Challenges
The path to commercial operations was not without obstacles. The plant faced multiple setbacks that delayed its full functionality for nearly two years following its initial inauguration. According to TNPDCL officials, the facility encountered complications after running for approximately 40 hours during testing phases, struggling to produce power beyond 650MW capacity.
"The plant must operate continuously for 72 hours to be declared fit for commercial operations," explained a TNPDCL representative. "There were technical issues after about 40 hours of operation, and we also experienced delays in obtaining necessary clearances from central authorities."
Successful Testing and Commissioning
At one point, officials considered certifying the plant at a reduced capacity of 650MW. However, Bharat Heavy Electricals Limited (BHEL), responsible for the balance of plant work, requested another opportunity to demonstrate the facility's full capabilities.
This persistence paid off when the plant successfully operated continuously from 4:30 AM on January 21 to 4:30 AM on January 24, generating electricity at its complete 800MW capacity throughout the 72-hour testing period.
Leadership Acknowledgment
TNPDCL Chairman J Radhakrishnan credited the systematic resolution of technical issues for enabling the plant to achieve full generation capacity. He specifically acknowledged the efforts of utility officials and BHEL engineers in reaching this significant milestone.
Future Power Projects
Looking ahead, TNPDCL officials have shifted their focus to the upcoming Udangudi thermal plant in Tuticorin, which boasts a planned capacity of 1,320MW. According to the official statement, coal-firing operations at this facility are scheduled to commence in the coming weeks, with initial production expected by March.
The successful commissioning of NCTPS Stage III represents a strategic enhancement to Tamil Nadu's power generation capabilities, particularly as the state prepares for the challenging summer months when electricity consumption typically reaches annual peaks.
