CEA issues transmission system plan for integration of over 500 GW RE capacity by 2030

The Central Electricity Authority (CEA) has issued a detailed transmission system plan for the integration of over 500 GW of non-fossil energy capacity by 2030. The planned systems include 8,120 ckt km of high voltage direct current transmission corridors (±800 kV and ±350 kV), 25,960 ckt km of 765 kV alternating current lines, 15,758 ckt km of 400 kV lines and 1,052 ckt km of 220 kV lines, at an estimated cost of Rs 2.44 trillion. The inter-regional capacity is expected to increase to 150,000 MW by 2030. The plan also envisages the installation of 51.5 GW of battery energy storage capacity by 2030 for the provision of round-the-clock power.
