New Delhi, Dec 15: Around 4,300 MW of solar power capacity in Rajasthan is facing 100 per cent daytime curtailment due to inadequate transmission infrastructure, putting projects worth nearly ₹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 affected. These projects are currently supplying power under the Temporary General Network Access (T-GNA) mechanism as their Associated Transmission Systems (ATS) are yet to be commissioned.
According to industry data, Rajasthan has about 23 GW of commissioned renewable energy capacity, while the available transmission capacity is around 18.9 GW. The entire transmission capacity has been allocated to projects with long-term General Network Access (GNA), leaving no evacuation margin for projects operating under T-GNA.
Although the 765 kV Khetri–Narela transmission line has been commissioned, it has added only about 600 MW of effective transmission capacity. At the same time, around 4,375 MW of capacity was operationalised under long-term GNA, exhausting the available surplus margins.
On December 11, the Northern Regional Load Despatch Centre (NRLDC) withdrew the No Objection Certificates (NOCs) granted to the 26 affected projects, following the commissioning of the Khetri–Narela line and operationalisation of long-term GNA.
Developers warned that prolonged curtailment could severely impact project viability and debt servicing, terming the situation a systemic risk as renewable generation capacity continues to outpace transmission additions in the state.
Industry representatives have urged the government to consider short-term relief measures, including the implementation of a Special Protection Scheme (SPS) to improve evacuation under T-GNA, dynamic reallocation of unused GNA margins to T-GNA projects, and the use of Dynamic Line Rating (DLR) to maximise real-time transmission capacity.
The industry has also suggested that a T-GNA-only approach be adopted for future renewable energy additions in Rajasthan until adequate evacuation margins are demonstrably available.
Meanwhile, ACME Solar Holdings Ltd said its 300 MW solar project in Rajasthan is not facing any evacuation constraints. The project, developed by ACME Sikar Solar Pvt Ltd and connected to the Bikaner-II substation, has received effective long-term GNA approval and is evacuating its full capacity, the company said.
ACME Solar added that following the commissioning of the Narela–Khetri transmission line, long-term GNA has become effective for around 4,300 MW of solar projects across multiple developers. The company has an operational renewable capacity of 2,934 MW and 4,586 MW under construction, including 15 GWh of battery energy storage capacity.
