It’s not terribly signal worthy imho. It’s obvious what are critical loads: finance, healthcare, telecom (local CO or your local datacenter, comms), government services such as first responders and dispatch, water/sewer. This is yet another excuse and data obfuscation to hide incompetence and less than good faith decisions.
ERCOT and utilities didn’t even to know which circuits not to shed to keep gas pipeline infra (compressor stations) running during the spring winter event.
Local permit data around electrical infra and ground truth from open data sources will take you far if you want to identify these loads. Folks answer a lot of questions they shouldn’t if you roll up with a hard hat, clipboard, and hi viz vest from your non descript pickup truck if you’re more bold.
Those are the ones that should be kept on line so it'd be interesting to see what areas if any retained power that don't have any of those critical facilities in them.
