Udangudi Super Critical Thermal Power Project is a proposed 1,320-megawatt (MW) coal-fired power station in Tamil Nadu, India.

The project is proposed by Tamil Nadu Generation and Distribution Corporation (TANGEDCO). Phase I would be 2 x 800 MW, and phases II and III would be 4 x 660 MW.

It is proposed that a project-specific jetty be built at Udangudi with coal transported to the power station via a conveyor system.[2]

In 2012, Udangudi Power Corporation stated on its website that "the required clearances from the concerned agencies are being obtained and the final clearance from MoEF will be obtained shortly. The proposed date of commencement of the project activities at site is Apr 2012 and the proposed date of commissioning of the plant will be 2016 - 2017."[3]

In 2012, chief minister J. Jayalalithaa cancelled the deal with BHEL. The government said Tamil Nadu Electricity Board would implement the project on its own, and fresh tenders were floated in 2013.[4]

In March 2015, the Tamil Nadu Electricity Board scrapped the bids for the power station, now 1320 MW, saying the bids were defective. The board said it would float fresh tenders soon, but it may take more than a year to finalize a new contractor to execute the project.[4]

In January 2018, a foundation stone was laid at the proposed project location. A construction contract for the plant was awarded to BHEL. Plans include establishing a captive coal jetty to import coal for the plant. Construction began on the jetty in mid-2018, and completion is planned for 2021. In September 2018, it was reported that fishermen were protesting construction of the jetty, saying it affected fish migration and restricted their movement.[5]

Construction on the coal plant began in 2019. The plant was reported to be 2 x 660 MW.[6]

Following severe flooding at the construction site caused by monsoon rains in December 2019, local residents alleged that check dams had been broken to allow the removal of stagnant water. The flooding suspended construction work.[7]

Phase II and III

In September 2015, TANGEDCO applied for a terms of reference for a phase II and III, each also 2 x 660 MW, which was approved in November 2015.[8]

There have been no developments on phases II and III since 2015, and they appear to be cancelled.


Before TANGEDCO, the project was sponsored in 2008 by Udangudi Power Corporation - a joint venture company under the auspices of state-run Bharat Heavy Electricals Ltd (BHEL) and the TamilNadu Electricity Board.[9][2][10]

In 2013, BHEL said it has exited Udangudi Power Corp. by selling its entire stake to joint venture partner Tamil Nadu Generation and Distribution Corp. (Tangedco). Following its restructuring in 2010, Tamil Nadu Electricity Board’s stake in the joint venture was transferred to Tangedco.[11]

Coal supply

Udangudi Power Corporation proposed that it will need 6.74 million tonnes per annum of coal which it states will be sourced from "Talcher Coal fields of Mahanadi Coalfields Limited in Orissa state and 30% Imported Coal from Indonesia, South Africa, Australia, China, etc.)"[12]


In January 2018, the Rural Electrification Corporation signed a loan agreement of US$1.64 billion with TANGEDCO for the Udangudi Thermal Power Project.[13][14]
