Though the state power minister, Mr Mrinal Banerjee today informed the House that by 2014, capacity of the generating stations will be enhanced by 3990 MW, his earlier promise of enhancing capacity is yet to be fulfilled. In 2006, the minister had stated in the house that the capacity of the generating stations under West Bengal Power Development Corporation (WBPDCL) would be enhanced by 1570 MW in 2007. But, the capacity will be enhanced by 900 MW.
