Grid management in the country, on a regional basis started in the sixties. At the beginning, 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.
- With time each grid was connected to the other, to allow greater availability and transfer of power.
- It all came together when the Southern Region was connected to the Central Grid, with commissioning of 765 kV Raichur-Solapur Transmission Line, thereby achieving ‘ONE NATION-ONE GRID-ONE FREQUENCY’.
- The Srinagar Leh Transmission System was connected to the National Grid, and was dedicated to the nation in 2019.
