State-owned NTPC Ltd’s capacity addition target of 66,000 mega watt for the Twelfth Plan period could take a knocking as legal hurdles hold up the placement of equipment orders for key projects slated to come up over the next five years. The company has been unable to go ahead with the placement of equipment orders for four super-critical projects in Maharashtra, Uttar Pradesh and Bihar as its bulk tender floated in 2009 for the supply of 11 boilers and 11 turbines of 660 MW each has been stuck in court.
