State -owned Bharat Heavy Electricals Limited (BHEL) has said that it has commissioned another 520 MW coal-based thermal generating unit in Andhra Pradesh.
The unit has been commissioned at the 2×520 MW Vizag Thermal Power Project of Hinduja National Power Company Limited (HNPCL), Visakhapatnam.
It may be noted here that 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.
The 2×520 MW Vizag Thermal Power Project has been executed by BHEL on EPC (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. 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 1×800 MW Dr. Narla Tata Rao Thermal Power Station (Dr NTTPS) Stage-V of Andhra Pradesh Power Generation Corporation Ltd (APGENCO) and 1×800 MW Sri Damodaram Sanjeevaiah Thermal Power Station (SDSTPS) Stage-II, popularly known as Krishnapatnam Supercritical Thermal Power Project, of Andhra Pradesh Power Development Company Ltd. (APPDCL).
On May 25, the company had announced the commissioning of the first 800 MW Supercritical Thermal Power Plant in Karnataka, which is also the highest rating unit in the state.
The unit was commissioned at the 2×800 MW Yeramarus Thermal Power Station (TPS) located in Raichur district of Karnataka. Yeramarus is being developed by Raichur Power Corporation Limited (RPCL) – a Joint Venture of Karnataka Power Corporation Limited (KPCL) and BHEL.
The second unit of this project is also in an advanced stage of construction and is expected to be commissioned shortly. BHEL’s scope of work for the project envisaged design, engineering, manufacture, supply, erection and commissioning of state-of-the-art supercritical Boiler and Turbine Generators along with associated civil works and agreed Balance of Plant (BoP) packages.
The key equipment for the project has been manufactured by BHEL at its Haridwar, Bhopal, Ranipet, Hyderabad, Jhansi, Thirumayam and Bengaluru plants, while the construction of the plant has been undertaken by the company’s Power Sector- Southern Region.
BHEL has been a major partner of KPCL in the development of Karnataka’s power sector. BHEL has supplied and executed 4,010 MW of coal-based sets for KPCL & its JV, accounting for 95% of their installed coal-based capacity. BHEL had earlier commissioned the 700 MW Bellary Stage-3 supercritical project in Karnataka.
The company is also presently executing KPCL’s first gas-based combined cycle power project of 370 MW capacity involving a fuel-efficient advanced-class gas turbine at Yelahanka. BHEL is the market leader in both the subcritical as well as the supercritical segments in the country.
BHEL has contracted 48 supercritical Steam Generators (Boilers) and 41 supercritical Steam Turbine Generators – the highest in the country by any power equipment manufacturer. Notably, in the fiscal 2015-16 itself, BHELhas been entrusted with orders for 12 supercritical Steam Generators and 10 supercritical Steam Turbine Generators by various utilities. Of the contracted sets, BHEL has already commissioned 11 supercritical Steam Generators and 9 supercritical Steam Turbine Generators in the country.
