BHEL achieves major landmark; Commissions 765/400 kV Raichur-Sholapur Transmission Link Synchronously-operated National Grid formed for One Nation-One Grid-One Frequency

Six months ahead of the contractual schedule, Bharat Heavy Electricals Limited (BHEL) has achieved a major milestone in its transmission business by successfully constructing and commissioning the 765/400kV Substation at Raichur in Karnataka, the Southern end of the 765 kV Raichur-Sholapur transmision link of POWERGRID.

Significantly, with the commissioning of the 765kV Raichur-Sholapur transmission link, the Southern Grid has been synchronized with the N-E-W Grid thus forming the synchronously operated National Grid, thereby fulfilling the ambition of One Nation- One Grid-One Frequency.

BHEL’s scope of work in the project included design, engineering, manufacturing, supply, erection, testing and commissioning of the 765/400 kV Substation package at Raichur. The project demanded the highest degree of competence in manufacturing and execution from BHEL's own manufacturing units and numerous sub-vendors.

This project will allow import of electricity from other regions to the Southern region during peak demand as well as export of surplus power from the Southern region during off-peak demand. BHEL is proud to have been associated with the execution of this historic transmission link. BHEL has always been committed to the nation’s power transmission programme and this achievement reaffirms its commitment to the growth of the transmission sector.

BHEL has a rich experience of more than four decades of setting up substations/switchyards on turnkey basis and has executed numerous transmission projects all across the globe. BHEL has indigenously developed and executed schemes using FACTs devices like Fixed Series Compensation for 400 kV lines for enhancing the power transfer capability & reducing transmission losses and Controlled Shunt Reactor (CSR) for dynamic reactive power management of long 400 kV transmission lines.

For controlling power flow in 400 kV transmission systems, BHEL has indigenously developed & supplied Phase Shifting Transformer. BHEL has also supplied ‘Static VAr Compensation’ (SVC) for transmission utilities and industries for Rolling mills & Furnace application and have also supplied STATCOM for industrial applications. BHEL is currently associated in the execution of the world’s largest ±800 kV, 6000 MW Ultra High-Voltage Multi-terminal DC transmission link between North East and Agra.
