New Delhi: A total of 48 GW of inter-state transmission (ISTS) capacity has been completed to evacuate renewable energy in India, Minister of State for Power Shripad Yesso Naik informed the Rajya Sabha on Monday. The transmission network is part of a larger national plan to establish 340 GW of inter-state transmission infrastructure for integrating 230 GW of solar and wind power into the grid.
The information was shared by the minister in a written response during the Monsoon Session of Parliament. “Out of the total planned capacity of 340 GW, 48 GW has been completed, 159 GW is under construction, 21 GW is under bidding, and 112 GW is under planning,” Naik stated.
The planned infrastructure is being developed in line with scheduled commissioning dates of renewable energy projects. Transmission schemes are approved by the Ministry of Power or other competent authorities accordingly, the minister said.
This large-scale transmission expansion is critical to India’s ambitious renewable energy goals, which aim to increase the share of clean power in the national mix while ensuring reliable, dispatchable electricity through grid connectivity.
In addition to inter-state efforts, the government is implementing the Green Energy Corridor (GEC) schemes at the intra-state level. GEC-I is underway in eight states — Karnataka, Madhya Pradesh, Rajasthan, Tamil Nadu, Andhra Pradesh, Gujarat, Himachal Pradesh, and Maharashtra — with a total outlay of Rs 10,141.68 crore.
GEC-II, which covers Gujarat, Himachal Pradesh, Karnataka, Kerala, Rajasthan, Tamil Nadu, and Uttar Pradesh, has a budgeted cost of Rs 12,031.33 crore. States have also been advised to prepare long-term intra-state transmission plans spanning a 10-year horizon to align with future renewable capacity additions.
