Is TN's Udangudi Thermal Plant Ready for Commissioning by March?
Synopsis
The Udangudi Supercritical Thermal Power Plant in Tamil Nadu is on track for commissioning, bolstering the state’s energy generation. With trial operations underway, key milestones are being achieved, promising a significant boost to Tamil Nadu's power supply. Stay tuned for updates on this vital energy project!
Key Takeaways
Trial operations of the first unit at Udangudi are underway.
The plant will add 1,320 MW to Tamil Nadu's energy capacity.
Investment in the project totals approximately Rs 13,077 crore .
TANGEDCO has built an offshore coal jetty to ensure coal supply.
Power generation during trials has reached a peak of 200 MW .
Chennai, Feb 8 (NationPress) The first trial phase has officially begun at the initial 660 MW unit of the Udangudi Supercritical Thermal Power Plant located in Thoothukudi district, representing a crucial milestone in enhancing Tamil Nadu’s power generation capabilities.
Officials have confirmed that the unit is making steady progress and is anticipated to be operational by March.
The Udangudi initiative, undertaken by Bharat Heavy Electricals Limited (BHEL) for the Tamil Nadu Power Generation and Distribution Corporation (TANGEDCO), comprises two supercritical units, each generating 660 MW.
Launched in 2019 with a projected budget of Rs 13,077 crore, the project aims to enhance efficiency and guarantee a stable power supply throughout the state.
To ensure a consistent coal supply, TANGEDCO has constructed an offshore coal jetty about eight kilometers from the shore of Kallamozhi. This dedicated jetty will facilitate the direct transportation of imported coal to the plant via a conveyor system once it becomes fully operational.
Currently, the jetty is pending necessary operational certifications.
The first unit is approaching completion, with the majority of critical components now installed.
During this trial phase, engineers have executed operational tests to assess collaboration among various departments involved in power generation.
In preparation, the plant has requested over 20,000 tonnes of coal from the Thoothukudi Thermal Power Station.
Over 10,000 tonnes have been delivered by road to the coal crushing unit at Udangudi to facilitate the initial operation. Following regulatory approvals, the boiler of Unit 1 was ignited, and the unit was successfully synchronized with the Southern Region power grid.
Power output during the trial averaged around 120 MW, peaking briefly at 200 MW.
The unit was subsequently shut down temporarily following testing and is scheduled for further operations to optimize performance and resolve minor technical issues identified during the trial.
Work on the second unit is also advancing, although turbine installations are still pending.
The construction of major infrastructure, including boilers and cooling towers, has been largely finished.
With the first unit's commissioning expected by March and the second by May, the Udangudi facility is set to contribute an additional 1,320 MW of capacity, greatly enhancing Tamil Nadu’s energy security and addressing rising industrial and domestic energy demands.
Point of View
It is essential to recognize the strategic importance of the Udangudi Thermal Power Plant. This project not only signifies a leap in Tamil Nadu's energy capabilities but also reflects the state's commitment to sustainable and efficient power generation. The successful commissioning of this plant will have significant implications for energy security and economic growth in the region.
