Nearly 4,300 MW of solar power capacity in Rajasthan faces complete daytime curtailment due to inadequate transmission infrastructure, putting projects worth about ₹20,000 crore at risk, industry sources said.
A total of 26 solar projects, developed by companies including Adani, ReNew, Serentica, Juniper, Zelestra, ACME and Amp Energy, are currently supplying power under the Temporary General Network Access (T-GNA) framework, as their associated transmission systems are yet to be commissioned.
With available transmission margins exhausted, power generation from these plants has been fully curtailed during daytime hours, sources said.
According to data from the Northern Regional Load Despatch Centre (NRLDC), Rajasthan has around 23 GW of commissioned renewable energy capacity, while transmission capacity stands at about 18.9 GW.
This entire transmission capacity has been allocated to projects with long-term General Network Access (GNA), leaving over 4 GW of capacity operating under T-GNA without evacuation capability.
Industry officials said that despite the commissioning of the 765 kV Khetri-Narela transmission line, only about 600 MW of additional transmission capacity became available. At the same time, over 4,300 MW was simultaneously operationalised under long-term GNA, effectively exhausting surplus margins.
In an email dated December 11, NRLDC withdrew the No Objection Certificates (NOC) for the 26 projects following the commissioning of the line and operationalisation of long-term GNA.
