It is one of the largest operational synchronous grids in the world with 417.68 GW of installed power generation capacity as of 31 May 2023.
A proposed interconnection between Myanmar and Thailand would facilitate the creation of a power pool and enable trading among all BIMSTEC nations.
Regional grids were initially interconnected by asynchronous HVDC back-to-back links facilitating limited exchange of regulated power.
[7][6] The union territories of Andaman and Nicobar Islands and Lakshadweep are not connected to the National Grid.
[11] The inter regional total transmission capacity (TTC) is 105,050 MW as on 30 June 2021.
[12] However the available transmission capacity (ATC) on daily basis is not exceeding 35% of TTC and the actual usage is around 25%.
[17] Presently, India is importing electricity from Bhutan with synchronous transmission links while exporting power to Nepal, Bangladesh and Myanmar with asynchronous transmission links between the National Grid and the electricity grids of these countries.
