The Union Ministry of Power has launched an ambitious plan for setting up an integrated transmission system of over 500 GW RE capacity by 2030. The plan is to connect all mega solar parks and wind power zones with the national grid at a total investment of Rs 2.44 trillion.
The planned additional transmission systems required for having 500 GW of non-fossil fuel include 8,120 ckm of High Voltage Direct Current Transmission corridors (+800 kV and +350 kV), 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 2.44 lakh crore. The transmission plan also includes transmission system required for evacuation of 10 GW off-shore wind located in Gujarat and Tamil Nadu at an estimated cost of Rs. 0.28 lakh crore.
With the planned transmission system, the inter-regional capacity will increase to about 1.50 lakh MW by 2030 from 1.12 lakh MW at present.
The plan has identified major upcoming non-fossil fuel based generation centres in the country, which include Fatehgarh, Bhadla, Bikaner in Rajasthan, Khavda in Gujarat, Anantapur, Kurnool RE Zones in Andhra Pradesh, offshore wind potentials in Tamil Nadu and Gujarat, RE park in Ladakh, etc. and based on these potential generation centres, transmission systems have been planned.
