Impure coal hits NTPC-Kaniha output
The 3,000 MW Kaniha station of National Thermal Power Corporation Ltd (NTPC), the second largest power plant in the country, has suffered generation loss of 133 million units (MU) in April-July period on receipt of inferior coal.
The power station has incurred generation loss of 85 MU in July alone. The generation loss in the April-July period of this coal-fired plant surpasses the 98 MU loss which the power station incurred in the whole of 2011-12, also because of poor quality coal from Mahanadi Coalfields Ltd’s (MCL) Lingaraj coal mines.
The daily average coal supply to the power plant has also dwindled from to 39,500 tonnes against the requirement of 55,000 tonnes. Low despatch together with poor and adulterated coal has hit power supplies to 17 states drawing power from this plant.
“The station has been receiving coal of inferior quality which is adversely affecting its generation level. The raw coal supplied to NTPC Kaniha contains rocks, soil and in some instances pieces of iron which leads to breakdown and impairs the plant's performance," said an official of NTPC-Kaniha.
“Poor quality coal pushes up the maintenance cost and curtails the longevity of plant equipment," he added.
Worried over falling generation, R C Patnaik, additional general manager of NTPC-Kaniha had shot off letters last month to general manager of Lingaraj area. Despite this, coal quality has not improved.
Officials of Lingaraj coal mines could not be reached for comments.
