We may never learn the truth about the Texas blackout

The reasons for the grid collapse are now a matter of intense debate. In the absence of detailed data the debate is mostly over general statistics, which do not establish causality.
Frozen wind turbines caused it.
A gas shortage caused it.
The gas shortage was caused by electrification of the pipelines.
Poor planning caused it.
Unpredictable need for electricity caused it.
ERCOT isolation caused it.
Climate change caused it.
It was an Act of God.
(Okay I have not heard that one yet. Wait for the liability issues.)
My personal conjecture, just to join the speculation crowd, is that a big frequency drop caused a mini-outage-cascade around 1:55 am Monday morning, automatically tripping off at least four big gas fired plants. Re cascades, big blackouts can be triggered by a frequency or voltage drop that causes one big generator to automatically trip off. This shock causes others to then auto trip in a cascade. Similar to stock market crashes causes by cascading automatic sell orders.
