Extreme Weather and Power Systems

Where this fits

How heat, cold, storms, wildfire and flooding can affect electricity supply and demand at the same time.

Core system ideas

Weather can raise demand while also reducing generation, transmission or distribution capability.

Regional events can limit mutual aid and create correlated equipment failures.

Planning scenarios should consider multi-day conditions and shared dependencies.

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

Weather-normalized demand, outages, deratings, restoration time and reserve conditions.
