Although the power major, NTPC has achieved substantial progress, in terms of obtaining the major clearances for the stage-II expansion of its coal-based thermal power project, located in the Ambedkar Nagar district of Uttar Pradesh, the water clearance from Central Water Commission (CWC) seems to be a bottleneck in the development of the 1,320 MW power station. The grant of clearance from CWC is pending since June 2008, albeit, the State's agreement on drawl of water, from the Saryu river, though the Tanda canal system, to meet the water requirement for this project, which is estimated to be of the order of 10,4400 cum per day.
The coal requirement for the project has been estimated to be 6.5 million tones per annum (MTPA), which will be sourced from the Chatti-Bariatu and Kerandari captive coal blocks of NTPC, located in the North Karanpura coalfields, about 600 km off the project site. Even though the expansion project has been proposed to be developed within the existing premises of the 4x110 MW thermal tower station, an additional land of 325 acre, would be required for the construction of the ash pond for the new units. The total area of the existing plant at Tanda is around 1,141.55 acres, out of which the ash pond area covers nearly 520 acres. The Expert Appraisal Committee (EAC) of the Ministry of Environment and Forests (MoEF) had deferred grant of clearance for this project seeking additional inputs from NTPC on the design of the ash disposal system, proposed to be developed to utilize the ash produced of these new units.
