State-run power giant NTPC is expected to end the current financial year with captive coal production of 7.25 million tonne, up a massive 170 per cent, from 2.68 million tonne in the year-ago period, a company official said. The official said that while output at NTPC's Pakri Barwadih coal mine at Jharkhand has seen a sizeable jump to 6.75 million tonne in FY19, from 2.68 million tonne in FY18, Dulanga coal mine in Odisha has started production as well. The Dulanga mine will end the current financial year with an output of 0.5 million tonne. "Mining of coal is integral to our overall fuel security strategy. A Greater degree of self-reliance in coal will go a long way in ensuring sustained growth of our power generation operations,\u201d the official said. \u201cWe made a debut in captive coal production just two years ago so the jump in output for the current financial year is encouraging.\u201d However, at 7.25 million tonne, the NTPC's captive coal production is still a fraction of its annual coal requirement of around 190 million tonne. The bulk of NTPC's coal requirement is currently met by Coal India, while small quantity is also imported. The first rake of coal from NTPC's Pakri Barwadih coal mine was flagged off in February 2017. Pakri Barwadih has block area of 46.26 sq km with a mine capacity 15 million tonne per annum and mineable reserve 641 million tonne. The NTPC has been allotted coal blocks including Pakri-Barwadih, Chatti-Bariatu, Kerandari, Dulanga, Talaipalli and Chatti-Bariatu (South), Banai, Bhalumunda and Mandakini B \u2013 for captive production so that it can meet the demand for fuel for its coal run power plants. These mines have total geological reserves of around 7.15 billion tonne with annual production potential of 107 million tonne. The total capacity for NTPC's coal fired power plants is currently at 45,500 MW. "We will ramp up coal production at Dulanga and Pakri Barwadih and bring more mines into production to boost the overall output in the coming years," the official said. The official refused to comment on the targeted output for the new financial year that starts on April 1, 2019, but said that the growth in captive coal production for financial year 2019-20 was likely to be robust and will take NTPC's output to double digits. In its annual report in 2017, NTPC had said that it plans to secure around 33 per cent of its total coal requirement through captive coal blocks by 2030.
