The unit has been commissioned at the 2x520 MW Vizag thermal power project of Hinduja National Power Co Ltd (HNPCL), Visakhapatnam, Bharat Heavy Electricals Limited said in a statement.

Significantly, in Visakhapatnam district, four 500 MW thermal sets supplied and executed by BHEL are already in successful operation at Simhadri Super Thermal Power Station of NTPC, it said.

The Vizag project has been executed by BHEL on engineering, procurement and construction basis. This project is located on the coast of the Bay of Bengal. Notably, this project uses single flow condenser and sea water as main cooling water, it added.

Though the project was severely affected by the Hudhud cyclone in 2014 while it was under construction, all out efforts were made by BHEL and HNPCL resulting in curtailing delays and commissioning both units.

BHEL has also recently secured prestigious orders for setting up two supercritical thermal power projects involving one unit each of the country's highest rating 800 MW sets, in Andhra Pradesh.

The projects are 1x800 MW Narla Tata Rao thermal power station stage-V of Andhra Pradesh Power Generation Corporation Ltd (APGENCO) and 1x800 MW Sri Damodaram Sanjeevaiah Thermal Power Station Stage-II, popularly known as Krishnapatnam Supercritical thermal power project, of Andhra Pradesh Power Development Company Ltd.
