Southern Grid integration by early 2014

Em News Bureau ,  Thursday, October 18, 2012, 17:37 Hrs  [IST]

The southern grid will be integrated to the National Grid in the first week of January 2014, Union power minister M. Veerappa Moily was quoted saying.

Once this integration takes place, the entire country will be seamlessly integrated by one grid, and at the same frequency. The natioanal grid currently has five components-northern, southern, eastern, western and northeastern. Since August 2006, all the subgrids, except southern, are interconnected. The southern grid is currently linked to the other grids asynchronously (at a different frequency) through a HVDC line.

The integration of southern grid will help states like Tamil Nadu, Andhra Pradesh, Kerala, Karnataka and Puducherry in getting their due share of power from the national grid.

The southern grid connectivity is based on a 800kV transmission line between Raichur in Karnataka and Sholapur in Maharashtra. This line is currently under construction with completion targeted for end-2013.

Currently, the total transmission capacity of the inter-regional links to the southern grid from other grids is 5,150 mw including 3,630 mw between the southern and eastern grids and 1,520 mw between the southern and western.

The total transmission capacity of inter-regional links connecting the regional grids has increased from 14,050 mw to 27,750 mw during the XI Plan period. A number of inter-regional links of 44,800 mw have been planned to be added during XII Plan or the early part of the XIII Plan period.
