Evolution of National Grid

  • Grid management on regional basis started in sixties.
  • Initially, State grids were inter-connected to form regional grid and India was demarcated into 5 regions namely Northern, Eastern, Western, North Eastern and Southern region.
  • In October 1991 North Eastern and Eastern grids were connected.
  • In March 2003 WR and ER-NER were interconnected .
  • August 2006 North and East grids were interconnected thereby 4 regional grids Northern, Eastern, Western and North Eastern grids are synchronously connected forming central grid operating at one frequency.
  • On 31st December 2013, Southern Region was connected to Central Grid in Synchronous mode with the commissioning of 765kV Raichur-Solapur Transmission line thereby achieving 'ONE NATION'-'ONE GRID'-'ONE FREQUENCY'.

 

Presently, the country has a total inter-regional transmission capacity of about 1,12,250 MW which is expected to be enhanced to about 1,18,740 MW by 2022.

Synchronisation of all regional grids will help in optimal utilization of scarce natural resources by transfer of Power from Resource centric regions to Load centric regions. Further, this shall pave way for establishment of vibrant Electricity market facilitating trading of power across regions. One Nation One Grid shall synchronously connect all the regional grids and there will be one national frequency.
