The commissioning of one 765 kV Raichur-Solapur transmission line took place in December,2013 and synchronous interconnection of Southern Regional (SR) grid with the rest of the grid was achieved, accomplishing the long cherished dream of 'One Nation-One Grid-One Frequency'.
With both the 765 kV transmission lines now in operation, the interconnection has helped achieving a pan-India synchronous grid of 249GW and one of the largest synchronous operating grids in the world.
Following are the benefits of the project
· Establishment of reliable and resourceful infrastructure for import of power from the regional grids of Northern, Eastern, Western and North-eastern regions (NEW) Grid to Southern region during peak demand as well as export of surplus power from Southern region during off- peak demand.
· Augmentation of inter-regional capacity of Southern region with rest of the grid, thereby overcoming the constraints being faced in meeting the Southern Region's maximum demand during summer season with the existing HVDC inter-regional links of Southern Region with Western & Eastern Regions.
· Provide access to bigger market for the existing and envisaged renewable generation capacity addition in resource rich Southern Region.
· Synchronous operation of the Southern Region with rest of the country for a robust and integrated power system, a boost for further economic growth.
