POWERGRID celebrates anniversary of One Nation-One Grid-One Frequency

What is the News?

As part of the Azadi Ka Amrit Mahotsav, POWERGRID is commemorating the landmark achievement of the completion of One Nation-One Grid-One Frequency.

Evolution of One Nation-One Grid-One Frequency

Grid management on a regional basis started in the 1960’s. State grids were interconnected to form a regional grid and India was demarcated into 5 regions namely Northern, Eastern, Western, North Eastern and Southern regions.

Then the integration of these regional grids and thereby establishment of a National Grid was conceptualised in the early 1990’s.

Initially, in 1991 North Eastern and Eastern grids were connected. In 2003, the Western region grid was connected with it.

In 2006, North and East grids were interconnected and then in 2013, the Southern Region was connected to the Central Grid. This helped in achieving ‘One Nation, One Grid, One Frequency’.

What are the benefits of One Nation-One Grid-One Frequency?

Firstly, synchronisation of all regional grids will help in optimal utilisation of scarce natural resources by transfer of Power from Resource centric regions to load centric regions. 

Secondly, this shall also help in the establishment of a vibrant Electricity market, facilitating trading of power across regions.
