-2.90 (-0.83%) National Thermal Power Corporation (NTPC) is planning to shut down two more units of 500 MW each in Orissa. The power utility major has already shut down two of its 500 MW units at Kanhia, near Talcher, in the state. The shutdown comes in the wake of a closure notice on June 28, by Orissa State Pollution Control Board (OSPCB) to the central public sector unit due to its faulty fly ash management plan. The NTPC has six power generation units (500 MW) at its Talcher Super Thermal Power Station (TSTPS) near Kaniha.crackcrack
