Major Causes of Grid Collapse
| Cause | Percentage | Description |
|---|
| Gas supply constraints | 28% | Thermal plants depend on gas availability; supply disruptions cause generation drops |
| Generation shortfall | 24% | Generation capacity insufficient to meet demand |
| Transmission faults | 20% | Aging transmission infrastructure and limited capacity |
| Frequency instability | 18% | Grid frequency drifts outside safe 49.5-50.5 Hz operating limits |
| Other | 10% | Weather, equipment failure, human error |
