India curtails 119 GW of renewables in September on grid bottlenecks

India curtailed 118.6 GW of solar and wind capacity in September due to grid, flexibility, and transmission constraints, with limited battery storage exacerbating the issue. The scale of curtailment signals a structural bottleneck in India's energy transition, potentially slowing renewable investment and raising power costs. Uncertainty remains over how quickly storage and grid upgrades can close the gap.
