Reply to comment by MintyLacroix in DC could face electricity blackouts overnight; residents urged to conserve electricity by Questioning-Pen

There was no blackout. PJM’s systems worked. Regardless, this was an operation to help the entire country grid system (notably by exporting to MISO). So it’s actually an exact example of something ERCOT couldn’t do to help itself last year. https://twitter.com/dr_a_stein/status/1606755212886147072?s=46&t=g4KpMovi-KJNnltFrF-dlw

Anyway, this is also an event that has caused trouble for all the power systems - rather than last year where exclusively ERCOT had issues during that cold snap.
