Electricity Department of Andaman and Nicobar (EDA&N) and the Lakshadweep Electricity Department (LED) are responsible for generation, transmission and distribution systems in these territories.

The inter regional total transmission capacity (TTC) is 105,050 MW as on 30 June 2021. However the available transmission capacity (ATC) on daily basis is not exceeding 35% of TTC and the actual usage is around 25%. Due to inter regional transmission constraints, the cost of power purchases by every

Due to the geography and topography of these islands, including separation by sea over great distances, there is no single power grid for all the electrified islands in the archipelago.

The first interconnection of regional grids was established in
October 1991 when the North Eastern and Eastern grids were interconnected. The Western Grid was interconnected with the aforementioned grids in March 2003. The Northern grid was also interconnected in August 2006, forming a Central Grid

with asynchronous transmission links between the
National Grid and the electricity grids of these countries. India is planning to build a minimum of 125 GW of wind capacity for Nepal 10 GW of hydro capacity for Nepal 20 GW of nuclear capacity and an undetermined amount of solar capacity by 2050

India began utilizing grid management on a regional basis in the 1960s. Individual State grids were interconnected to form 5 regional grids covering mainland India. The grids were the
Northern, Eastern, Western, North Eastern and Southern Grids. These regional links were established to enable

Southern Grid, was synchronously interconnected to the Central Grid on 31 December 2013 with the commissioning of the 765
