Bhel commissions Jhajjar thermal power project’s 3rd 500-mw unit

Bharat Heavy Electricals Ltd (Bhel) has achieved a major milestone in the execution of mega power projects with the successful commissioning of the third 500 mw unit at the Indira Gandhi Super Thermal Power Project (IGSTPP), Jhajjar-Stage-I of Aravali Power Company Private Ltd (APCPL), a joint venture of NTPC, IPGCL and HPGCL.

With this, 12 million units of electricity will be added every day to the grid, which will be shared by the power deficit states of Haryana and Delhi.

Bhel has earlier commissioned two 500 MW units at the power project. With the commissioning of the third unit, project has now been completed and the cumulative generating capacity of IGSTPP, Jhajjar, has gone up to 1,500 mw (3x500 mw).

The full load operation of the unit has been achieved within a record time of 2:10 hours of the unit getting synchronised with the grid.

This is the fourth unit of 500 mw that Bhel has commissioned for NTPC during the current financial year. With the commissioning, BHEL has added a total of 3000 mw to the grid during financial year 2012-13.

The main plant package contract for the 3x500 mw IGSTPP, Jhajjar, was placed on Bhel by APCPL under international competitive bidding (ICB) and is a testimony to the customer’s confidence in Bhel’s capabilities and technological excellence.

Bhel’s scope of work in the contract envisaged design, engineering, manufacture, supply, erection, testing and commissioning of three boiler, turbine, generator sets of 500 mw each, with associated auxiliaries and state-of-the-art controls & instrumentation (C&I), while the balance of plant is being executed by APCPL.

The boiler and turbine generators were manufactured at the company’s Trichy and Haridwar plants respectively while the C&I system was supplied by Bhel’s Electronics Division, Bangalore.

The company’s Hyderabad plant manufactured the boiler feed pumps and heat exchangers and the electricals were supplied by Bhel’s Bhopal and Jhansi plants.

For NTPC, Bhel is currently executing contracts at Barh (2X660 mw) and Mauda (2X660 mw) supercritical sets, Vallur (2X500 mw), Rihand (1X500 mw), Mauda (1X500 mw), Vindhyanchal (2x500 mw), Bongaigaon (3X250 mw), Muzaffarpur (2X195 mw) and Nabinagar (4X250 mw).

Bhel has fully established state-of-the-art technology for manufacture of thermal sets up to 600 mw rating in the sub-critical range and has the capability to manufacture sets up to 1,000 mw rating.

The company has also equipped itself to produce 660 mw/ 700 mw/ 800 mw thermal sets with super-critical parameters, and is shoring up its capability for higher rating hydro sets and advanced class gas turbines to cater to upcoming market requirements.

Bhel has established the capability to deliver power plant equipment of 20,000 mw per annum.
