The Ministry of Power (MoP) constituted a high-level committee for planning the transmission system required for having 500 GW of non-fossil fuel based installed capacity by 2030. The committee prepared a detailed plan titled “Transmission System for Integration of over 500 GW RE Capacity by 2030″ in consultation with states and other stakeholders. The plan serves as a major step towards achieving the goal of integrating 500 GW of non-fossil fuel-based capacity by 2030 by providing a broad plan of required transmission system for having 537 GW of renewable energy capacity by the year 2030.
The plan comprises 8,120 ckm of high voltage direct current transmission corridors, 25,960 ckm of 765 kV AC lines, 15,758 ckm of 400 kV lines and 1,052 ckm of 220 kV cable at an estimated cost of Rs 2.44 trillion. The transmission plan also includes transmission system required for evacuation of 10 GW offshore wind projects located in Gujarat and Tamil Nadu at an estimated cost of Rs 0.28 trillion. With the planned transmission system, the inter-regional capacity will increase to about 150,000 per MW by 2030 from 112,000 per MW at present.
Considering the availability of renewable energy-based generation for a limited period during the day, the plan also envisages installation of battery energy storage capacity of the order of 51.5 GW by 2030 to provide round-the-clock (RTC) power to consumers.
This plan has identified major upcoming non-fossil fuel-based generation centres in the country which includes Fatehgarh, Bhadla, Bikaner in Rajasthan, Khavda in Gujarat, Anantapur, Kurnool renewable energy zones in Andhra Pradesh, offshore wind potentials in Tamil Nadu and Gujarat, renewable energy park in Ladakh. Based on these potential generation centres, transmission systems have been planned.
The planned transmission system project will provide visibility to the developers about the potential generation sites and scale of investment opportunity. Further, it will also provide the transmission service providers the vision of growth opportunity available in the transmission sector along with investment opportunities of about Rs 2.44 trillion.
