Electric Grid Resilience

Where this fits

How power systems prepare for, absorb, adapt to and recover from major disruptions.

Core system ideas

Resilience includes prevention and hardening, but also isolation, alternate supply, mutual assistance and restoration.

Extreme weather can affect generation, fuel, transmission, distribution and communications simultaneously.

Restoration priorities consider life safety, critical services, network dependencies and available crews/materials.

Interfaces and tradeoffs

Reliability involves both routine adequacy and the ability to remain within acceptable conditions after disturbances. Fast controls, reserves, protection, asset condition and trained operators contribute at different timescales.

What organizations measure

Customers interrupted, restoration time, asset damage, spare capacity and recovery milestones.
