Background

The plant was established under the mega power project policy.[1] The erstwhile Tamil Nadu Electricity Board (TNEB) and the NTPC, in a joint venture, formed the NTPC Tamil Nadu Energy Company Limited. The foundation stone for the Vallur thermal plant was laid on 5 September 2007.[2] [3][4] The projected was constructed in two phases: phase I with two 500 and phase II with one 500 MW unit. Initially expected to be operational by 2010, the project was delayed due to the late implementation of the coal-handling facility established by the BHEL.[2] Erection of the boiler column began on 5 January 2009.[3]

In September 2009, the contract to supply units for Vallur was given to BHEL, which supplied and installed steam generator and steam turbine packages. BHEL was responsible for the design, engineering manufacture, supply, erection and commissioning of the steam generators, turbine generators, electrostatic precipitators and associated auxiliaries, and controls and instrumentation systems in the plant.[1]

The 216-tonne boiler drum of Unit I was erected in June 2010. Unit I was commissioned in March 2012 but operating at full capacity was delayed further due to problems with coal-handling facilities. Independent works on phase II began in 2010.[1]

The first, second and third units were synchronised with the grid on 9 March 2012, 26 February 2013 and 28 February 2014, respectively.[5] The total cost of the project without IDC was 91,930 million rupees.[5] The plant commenced its commercial operation on 29 November 2012, with the operation of its first unit. The second unit commenced its commercial operations on 25 August 2013,[5] while that of the third unit was commenced on 28 February 2014.[6]

Cost and finance

The cost of phase I was 54 billion rupees (US$1.15 billion) and that of phase II was 30 billion rupees (US$639 million). The debt equity ratio of the project is 7:3. The Rural Electrification Corporation (REC) sanctioned 38 billion ruppes ($809 million) to meet the entire debt portion of the project. REC advanced a loan of 21 billion rupees ($447 million) for the second phase in April 2010.[1]

The project comprises units, with status as follows:[7][8]

  • Unit 1 - 500 MW - was commissioned on March 28, 2012.[9]
  • Unit 2 - 500 MW - was commissioned in February 2013.[7]
  • Unit 3 - 500 MW - commissioned in February 2014.[7]
