To meet the growing power demand in India, transmission & distribution system between resource
generation and bulk consumption centres are being enhanced continuously. High capacity transmission
corridors comprising 765 Kv AC and ±800 Kv 6000 MW HVDC system along with 400 Kv AC and ±500 Kv/600
Kv 2500 MW/6000 MW have been planned to facilitate transfer of power from remotely located generation
facilities to bulk load centres.
The focus is on development of future power system with upgrading of existing
transmission system, adopting technology suitable for bulk power transfer over long distances like high
capacity EHV/UHV AC system, HVDC system, compact tower/substation, mitigating devices to address high
short circuit level, intelligent grid etc. The capacity of transmission system of 220 Kv and above voltage levels
in the country as on 31 August 2016 was 3,50,792 ckm of transmission lines and 6,86,384 MVA of
transformation capacity of substations.
SPML is among the largest contributor of power transmission & distribution in India. Millions of households
across the country have benefited through SPML‘s power transmission and distribution initiatives.
