PGCIL, to put it briefly, is into the planning, executing, owning, operating and maintaining of high voltage inter-state electricity transmission systems in the country. It has been notified as the Central Transmission Utility (CTU) of the country.

It is the company’s responsibility to connect and operate India’s five major power regions of north-eastern, eastern, western, northern, and southern, so as to enable the transfer of electricity throughout the country from the point of generation to the points in various states where the power is needed.

The company currently carries about 45% of the total power generated in the country on its transmission network. PGCIL has a pan India presence with around 70,000 circuit km (ckm) of transmission network and 120 EHVAC (extra high voltage direct current) and HVDC sub-stations with a total transformation capacity of 79,500 MVA. Of late, PGCIL has also diversified into the telecom business to utilise the spare capacity on its country-wide transmission infrastructure and established a telecom network of over 20,000 km across the country, thus helping it also generate revenues from major telecom players in mobile and national long distance segment.
