"The commissioning of the steam turbine has enabled the gas turbine, which was commissioned earlier, to operate in combined cycle mode," BHEL said in a statement.
Rajasthan Rajya Vidyut Utpadan Nigam Limited (RRVUNL) had placed the order on the company, for setting up a Gas Turbine based 160 MW CCPP as an expansion project of Ramgarh power plant in Jaisalmer district of Rajasthan.
With the commissioning of this plant, the cumulative capacity of Ramgarh CCPP has now reached 273.8 MW, taking the gas based generating capacity of RRVUNL to 603.8 MW.
The main plant equipment of all these gas-based units has been supplied and commissioned by BHEL.
BHEL's scope of work in the contract envisaged design, engineering, manufacture, supply, erection and commissioning of the Main Plant and equipment for the Gas-based power project comprising one Gas Turbine with Generator, one Heat Recovery Steam Generator, one Steam Turbine Generator and Associated Auxiliaries with Controls and Instrumentation system.
The equipment for the project was supplied by BHEL’s Hyderabad, Trichy and Bangalore plants, while BHEL’s Power Sector – Northern Region - undertook erection and commissioning of the equipment.
BHEL has commissioned 4,344 MW of thermal and gas-based sets in Rajasthan which amounts to 88 per cent of the utility’s thermal and gas generating capacity, the statement said.
For RRVUNL, BHEL is also executing the 250 MW Unit 4 at Chhabra thermal power station, which is expected to be commissioned in May, 2014.
BHEL has so far commissioned more than 15,000 MW of combined cycle gas based sets for the utility sector and captive and industrial applications in the country, the statement added.
