5 GW Solar Output Curtailed in Rajasthan
Grid congestion hits Adani, NTPC Green, JSW; developers flag revenue losses
- Up to 5 GW of peak solar power curtailed in Rajasthan
- Grid congestion and limited transmission capacity cited as key reasons
- Adani Group, NTPC Green and JSW among affected developers
- Industry warns of revenue losses and green energy wastage

Jaipur, 15th Dec: Leading solar power producers, including the Adani Group, NTPC Green Energy and the JSW Group, are facing major revenue losses following the forced curtailment of up to 5 gigawatts (GW) of peak solar power generation in Rajasthan due to grid congestion and inadequate transmission infrastructure.
Industry sources said solar power evacuation was curtailed by as much as 50–55 per cent during peak generation hours in certain pockets of the state, as grid operators prioritised system stability amid capacity constraints. The situation has led to large-scale wastage of renewable energy despite strong solar generation conditions.
Developers said the curtailment is being driven primarily by insufficient transmission capacity and grid security concerns, particularly during midday hours when solar generation peaks. Several large projects were asked to back down production despite being technically capable of supplying power.
The financial impact on developers has been severe. According to industry estimates, some solar producers are reporting monthly revenue losses exceeding ₹20 crore due to repeated and prolonged curtailment. The losses are particularly acute for projects operating under must-run status, where generation is expected to be evacuated unless grid security is at risk.
Renewable energy companies have warned that persistent curtailment without timely augmentation of transmission infrastructure could undermine investor confidence and slow down future investments in India’s clean energy sector. They stressed that unless grid bottlenecks are urgently addressed, valuable green power will continue to be wasted at a time when India is pushing aggressively towards its renewable energy and net-zero targets.
Rajasthan is one of India’s largest solar power hubs, hosting several gigawatts of installed capacity. Developers and industry bodies have called for faster execution of transmission projects and better coordination between generation and grid expansion to ensure that renewable energy growth is not constrained by infrastructure gaps.
