Tndian power system is expanding at high rate with present installedcapacity is about 1,64,000 MW Power demand is expected 1 to further increase to about 220 GW by 2017 and 370 GW by 2022 in next 10–12 years for which total installed capacity of about 480 GW is envisaged. However optimal utilization of unevenly distributed energy resources in the country along with severe right of way issue and phase-wise development of transmission infrastructure necessitates establishment of high power transmission corridors. Towards this, a number of transmission corridors comprising 765 kVAC, 1200 kVAC, ± 800 kV,6000 MW HVDC system have been planned/under implementation. This paper presents major considerations for development of 1200 kV AC system along with a case study. Proposed 1200 kV system parameters are also highlighted.
