The Indian power infrastructure developer Sterlite Power has been awarded an Interstate Transmission System (ISTS) project for the evacuation of 20 GW of power from Renewable Energy Zones (REZ) in the state of Rajasthan (western India), which comprises the construction of a 765 kV transmission line that will span 350 km between the Fatehgarh III REZ and Beawar in the Ajmer district.
The ISTS project will enable the evacuation of renewable power from the Fatehgarh (9.1 GW), Bhadla (8 GW) and Ramgarh (2.9 GW) REZs of Rajasthan. The project was bid out through a tariff-based competitive bidding process under India’s Phase-III Part G scheme.
Earlier in March 2023, Sterlite Power commissioned the 5 GW Lakadia-Vadodara electricity transmission project, which is set to deliver power from the wind and solar energy zones of Bhuj and Kutch, in the Indian state of Gujarat, to the rest of the country.
In December 2022, India’s Power Ministry unveiled a INR2,440bn (US$30bn) plan to build over 50,000 km of electricity transmission lines, intended to evacuate India’s planned renewable power capacity of 500 GW by 2030. The transmission infrastructure required includes 8,120 km of high-voltage direct current (HVDC) transmission corridors, 25,960 km of 765 kV alternative current lines, 15,758 km of 400 kV lines and 1,052 km of 220 kV cable.
