Rajasthan has an estimated spare transmission capacity of up to 13 GW in the financial year (FY) 2026 for future renewable energy projects, according to the state’s load dispatch center, Rajasthan Rajya Vidyut Prasaran Nigam (RVPNL).

Rajasthan will have up to 1.4 GW of spare transmission capacity in FY 2027 and up to 3.9 GW of capacity in FY 2028. The available transmission capacity will drop to 1.9 GW by FY 2029.

The state has approved transmission capacity for renewable energy projects of more than 1 GW, comprising 997.21 MW for solar/biomass projects, and 105.7 MW for wind projects.

According to RVPNL, at the existing and newly approved 400 kV grid substations, the state will have spare grid capacity of only 1,900 MW in FY 2029. Currently, it has no approved capacity.

At the existing and newly approved 220 kV grid substations, the state will have capacity available until FY 2028. As per RVPNL estimates, the state will have spare transmission capacity of 4,375 MW in FY 2026, 200 MW in FY 2027, and 3,330 MW in FY 2028.

At the 220 kV level, the state has approved transmission capacity for renewables of up to 706 MW, comprising 653 MW for solar/biomass projects and 53 MW for wind projects.

At the existing and newly approved 132 kV grid substations, transmission capacity will be available until FY 2028. At the 132 kV level, Rajasthan will have 8,965 MW of spare transmission capacity in FY 2026, 1,155 MW in FY 2027, and 600 MW in FY 2028.

The state has approved a total transmission capacity of up to 396.9 MW for renewable projects, comprising 344.2 MW for solar projects and 52.7 MW for wind projects at the 132 kV level.

Between March and August 2025, Rajasthan experienced significant curtailments of up to 4 GW of solar and wind generation due to inadequate transmission infrastructure.

According to Grid-India’s ‘Operational Feedback on Transmission Constraints (April-June 2025)’ report, a delay of over 18 months in commissioning a transmission system strengthening program has created bottlenecks for evacuating 8.1 GW of power from a renewable energy zone in solar-rich Rajasthan.
