"A strategy would be devised soon to clear the encroachment for making of lagoon. We will not let NTPC suffer its operation," the DM said. The NTPC GGM said after filling of lagoon A,B and C the plant got a new lagoon digged on June 15 this year for dumping its ash slurry. "But, the lagoon 2 has the potential to function for nine months and after that there is no other option but to create lagoon 3 at Majdaha village," Mishra said. Kahalgaon unit is the seventh in the series of Super Thermal Power project set up by NTPC in 1987. It has installed capacity of 4x210 MW (Stage I) and 3x500 MW (stage-2) totalling 2340 MW. It provides 41 per cent of the total electricity generated to Bihar. The NTPC Kahalgaon GGM said they took utmost care for waste management by creating check points. Giving details, he said the plant had six bagging machines from which ash slurry were filled in big bags and transported to North Eastern states of Assam and Tripura among others for its utilisation in cement manufacturing.
