"These new state-of-the-art machines have a better heat rate, leading to a direct reduction of coal consumption to the tune of 12,000 tonnes per annum per unit. The units also comprise advanced control, instrumentation and monitoring system," BHEL officials said here.

This is the second 490-MW unit at the Dadri Thermal Power Plant having higher steam parameters ensuring reduced coal consumption and better performance with regard to the environment, they added.

Significantly, these are first-of-their-kind indigenous units, which have been designed for operating at a higher reheat steam temperature of 565 degrees Celsius.

Ninety per cent of the power generated from the second unit would be supplied to Delhi to meet its requirement during the forthcoming Commonwealth Games.

BHEL has fully established state-of-the-art technology for the manufacture of thermal generators up to a 1,000-MW rating. To meet customer demand, the company has introduced new rating thermal sets of 270-MW, 525-MW and 600-MW capacity, in addition to 250 MW and 500 MW thermal sets.

BHEL has so far secured 93 orders for 490/500/525/600 MW thermal sets. BHEL has also introduced supercritical thermal sets of 660 MW capacity and above in its manufacturing range.

At present, BHEL is executing supercritical projects involving nine boilers and seven turbine gensets (TG) for NTPC, APGENCO, JaiPrakash Associates and Raichur Power Corporation Ltd, among others, BHEL said.

The company has established the capability to deliver 15,000 MW of generation capacity per annum and further augmentation to 20,000 MW per annum is underway.
