Developments in power sector emphasize the need for accelerated implementation of National Power Grid on priority to enable scheduled/ unscheduled exchange of power as well as for providing open access to encourage competition in power market.

In view of above, nationwide synchronous power grid, interconnecting all the five regional grids, has been established with the commissioning of 765kV S/c Raichur – Sholapur line on December 31, 2013.  POWERGRID is strengthening its transmission network to establish inter-State and inter-regional links for enhancing the capacity of National Grid in a time bound manner to ensure optimal utilization of uneven distribution of energy resources. As on 31st January 2024, Inter- regional (IR) Transmission Capacity has reached to cumulative figure of 1,16,540 MW.
