Bharat Heavy Electricals Limited (BHEL) has commissioned a 660MW supercritical unit for the second stage of the Barh Supercritical Thermal Power Project (TPP) in Bihar, a state in India.

The installation is the second for the facility, which is being developed by the state-owned NTPC.

The first supercritical thermal power unit installed at the facility by BHEL in November 2014 also had a generation capacity of 660MW.

BHEL has manufactured the key equipments for the project at its facilities in Haridwar, Trichy, Hyderabad, and Bengaluru.

"Thesupercritical units for thermal power plants can deliver increased efficiency at reduced coal consumption."

BHEL’s Power Sector for the Eastern Region was responsible for the construction of the facility.

The company is presently executing orders for 36 sets of supercritical boilers and 31 sets of supercritical turbine generators, all of which are in various stages of execution.

The orders have been sourced from central, state as well as private sectors, BHEL said.

As well as being eco-friendly options, the supercritical units for thermal power plants can deliver increased efficiency at reduced coal consumption, BHEL claims.

The firm is presently co-ordinating with NTPC and IGCAR for domestic development of the advanced ultra supercritical (AUSC) technology.

If successful, the advanced technology can promise a further 11% reduction in coal consumption and carbon dioxide emissions.
