Not to spread concern or anything, but the electrical grid is managed and controlled by software. And that software may or may not be very reliant on AWS. I’m probably not allowed to say more than that.
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.

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.
