Recently Power Grid Corporation of India Limited (PGCIL) celebrated the anniversary of operation of ‘One Nation-One Grid-One Frequency’ i.e. National Grid.

National grid management on a regional basis started in the 60
The Indian power system is divided into five regional grids for planning and operational purposes.
In the early nineties, the concept of integration of the regional grid and thus the establishment of a national grid was conceived.
Initially the state grids were interconnected to form a regional grid and India was demarcated into 5 regions namely North, Eastern, Western, North Eastern and Southern.
In the year 1991, the North-Eastern and Eastern grids were connected. Apart from this, in the year 2003, the Western Region Grid was connected to it.
In August 2006 the North and East grids were interconnected, making 4 regional grids connected synchronously and operating on the same frequency as a central grid.
Southern Region was connected to the Central Grid on 31st December To achieve ‘One Nation, One Grid, One Frequency’.
All possible measures are taken to ensure that the grid frequency always remains within the 90-50.05 Hz band.

Maintaining a consistent power frequency is important because many frequencies cannot operate alongside each other without damaging the equipment.
This has serious implications while providing electricity at the national level.

The country currently has a total inter-regional transmission capacity of about 1, 12,250MW, which is expected to increase to about 1, 18,740MW by the year

Demand-supply matching: Coordination of all regional grids will help in optimum utilization of scarce natural resources by transfer of electricity from resource-intensive areas to load-intensive areas.
Development of electricity market: In addition, it will pave the way for the establishment of a vibrant electricity market, which will facilitate trade in electricity in all regions.
