Power company engineer here, it’s true that a lot of our supporting and analytics software went down during the AWS event.

However, most devices that actually control grid units (called bulk electric system cyber-assets) are air-gapped or utilize a data diode.

FERC Reliability Standards and NERC CIP

However-er, flipping through those standards just now, turns out it’s 100% permitted to connect your “bulk electric system cyber-asset” to a cloud integration if done compliantly.

The process to decide to turn power plants on and off isn't air-gaped.
