- **2026-05**: Peak curtailment during record demand — Scorching heat sent electricity use to an all-time high, and grid curtailment hit its highest level of the quarter.
- **2026-04**: Q2 curtailment period begins — During April-June, India's transmission system failed to absorb more than 8 billion kilowatt-hours of power after 63 billion kWh actually reached the system.
