State-owned Bharat Heavy Electricals Ltd has commissioned its first 660-MW super critical thermal unit at a NTPC power plant in Bihar.

The power equipment major on Sunday said its 660 MW Boiler Turbine Generator (BTG) unit, having super critical parameters, attained full load at the Barh thermal project.

This package for Stage II Unit 4 of the project being implemented by NTPC.

“The supercritical steam parameters for this project — efficiency and heat rate are better than those of comparable supercritical projects presently under installation by others,” BHEL said in a statement.

The maiden order for 660 MW sets were won from NTPC through international competitive bidding for this 1,320 MW project. The scope of work included design, engineering, manufacture, supply and erection along with auxiliaries.

At present, BHEL is executing orders for supply and installation of 27 steam generators and 24 turbines with supercritical parameters of 660 MW, 700 MW and 800 MW ratings.

Other supercritical sets under execution include 2x660 MW Mouda Stage-II & 2x800 MW Gadarwara of NTPC; 3x660 MW Nabinagar of NPGCL (Joint Venture of NTPC and Bihar State Electricity Board); 3x660 MW Bara TPP of the Jaypee Group; 2x800 MW Yeramarus of Raichur Power Corporation Ltd; 3x660 MW Lalitpur of the Bajaj Hindustan Group; 2x800 MW Krishnapatnam of APGenco and and 2x660 MW Raghunathpur of DVC.
