Four states have sought an extension until December 2025 to implement the Intrastate Transmission System Green Energy Corridor Phase-I (InSTS GEC-I).

While Andhra Pradesh, Maharashtra, Gujarat, and Himachal Pradesh have requested a further extension beyond June 2025, Rajasthan, Karnataka, Madhya Pradesh, and Tamil Nadu have completed the implementation of the green energy corridor, Shripad Naik, Minister of State in the Ministry of New and Renewable Energy (MNRE), told the Lok Sabha.

The Minister also shared the details of the state-wise funds approved and released under the program.

In seven states — Gujarat, Himachal Pradesh, Karnataka, Kerala, Rajasthan, Tamil Nadu, and Uttar Pradesh — implementation of the second phase of the intrastate green energy corridor program is on.

The government had approved the second phase in 2022. This phase is scheduled for completion by the end of the financial year 2026. Phase-II involves setting up about 10,750 circuit kilometers (ckm) of transmission lines and 27,500 MVA of substation capacity to integrate 20 GW of renewable energy generation capacity.

The Minister said the government has taken the following technology initiatives to facilitate India’s renewable energy evacuation:

• Establishing renewable energy management centers for real-time forecasting, scheduling, and monitoring of renewable energy generation across the 12 renewable energy-rich regions
• Introducing guidelines for procurement and utilization of battery energy storage systems
• Establishing high-voltage direct current corridors for long-distance renewable energy transfer
• Introducing guidelines for developing pumped storage projects
• Introducing ancillary services from energy storage systems under the CERC (Ancillary Services) Regulations, 2022

The green energy corridor program aims to synchronize electricity produced from renewable sources, such as solar and wind, with conventional power stations in the grid.

The third phase of the green energy corridor will involve the construction of 8,862 ckm of new transmission lines and 9,500 MVA of capacity.
