After that, in November 2021, NTPC reissued the tender. In the latest tender, the bidders’ average annual turnover requirement was increased.


The average annual turnover of bidders for the first block was raised to ₹900 million (~$12 million) and ₹1.8 billion (~$24 million) for the second block. Earlier, the minimum financial requirement for the first block was ₹670 million (~$8.81 million), and for the second block, it was ₹1.34 billion (~$17.61 million).
