Mechanism
Standby Redundancy
TL;DR
EDF's reserve generation capacity illustrates standby redundancy: reserve generators maintain partial operation or standby readiness, ramping up when needed.
Backup systems are maintained ready but not actively operating. When primary systems fail, backup systems activate.

EDF's reserve generation capacity illustrates standby redundancy: reserve generators maintain partial operation or standby readiness, ramping up when needed. Reduces operating costs but introduces switchover delays. AWS Availability Zones use this approach - backup data centers ready to activate within minutes.
