Central Electricity Authority (CEA) has come up with a plan to build transmission capacity for 613 GW of renewable energy by 2032. In its recently released ‘National Electricity Plan', the CEA estimates that India will have 653 GW capacity for electricity generation from non-fossil fuel, comprising 385 GW from solar (including 60 GW rooftop solar), 165 GW wind, 62.8 GW hydro, 19.6 GW nuclear, 15.5 GW biomass, and 5.4 GW small hydro.

This is the “likely installed generation capacity' (MW) in 2031-32 for planning of transmission systems. Total installed electricity generation capacity is expected to be 997 GW by 2031-32. With India's solar and wind power capacities at 90 GW and 47 GW, respectively, the CEA assumes the country will add 295 GW of solar and 118 GW of wind capacity in the next eight years and four months.

Several STATCOMs have been planned along with BESS and pumped storage plants to improve stability. An estimated expenditure of Rs 4.9 lakh crore (Rs 3.9 lakh crore inter-state and Rs 99,296 crore intra-state) would be required during 2027-32 to build additional transmission systems of 220 kV and above voltage, as per the CEA.
