The report in particular said that 67% of the lost capacity was directly attributable to cold weather, specifically frozen sensing lines, frozen water pipes, windmill blade icing, etc. A remaining 12% of the shortfall was secondarily caused by the weather, specifically plants running low on fuel. This leaves a remaining 21% for “other”, which presumably includes downed lines. I wouldn’t call that the “major” problem, not compared to the 67% caused by the plants freezing.

As far as 1989 being 30 years ago: it’s still within living memory. It’s not like we’re talking about the 1899 freeze or whatever, lots of people in Texas remember it! So far Texas has had power issues due to the cold in 1989, 2011, and 2021. I think by the point you’re having this every 10-20 years, it’s time to start planning for it, no?
"A total of 210 individual generating units within the footprint of the Electric Reliability Council of Texas (ERCOT), which covers most of Texas, experienced either an outage, a derate, or a failure to start. The loss of generation was severe enough on Feb. 2 to trigger a controlled load shed of 4 GW. Spot prices in ERCOT hit the $3,000 per MWh cap on Feb. 2, the worst day of the event. The following day, local transmission constraints coupled with the loss of local generation triggered load shedding for another 180,000 customers in the Rio Grande Valley in south Texas."
that is not close to the severity of what happened over the course of this week.
"According to the Electric Reliability Council of Texas, which manages 75% of the state's deregulated electricity market, the single-day record for demand, set in 2018, was smashed on Valentine's Day. And as the weather has gotten worse, the capacity to generate electricity has diminished: By Tuesday, per ERCOT's CEO, 45,000 megawatts of generating capacity was offline — up from 34,000 megawatts offline the day before, representing more than half of what the state typically uses in a day.

Right, but I wasn't claiming that 2011 was as bad as 2021, which would be an obviously silly claim. I'm claiming that in 2011 the grid failed in a similar way to what's happening today, due to the cold, and that it was a failure of leadership to not learn from that and prepare (El Paso excepted). This is why I talked about why power failed in 2011, rather than talking about how long the outage in 2011 was or how cold it got.
Meanwhile I am saying that this claim you made is in contradiction with the official report:
> The major problems in 2011 were trees falling on power lines it wasn't core generation facilities failing.
The FERC claims that 79% of the lost energy production in 2011 was caused by either power plants failing directly due to the cold (67%), or indirectly as fuel production and transport failed due to the cold (12%). Between your unsupported assertion about falling trees, and the report produced by experts who spent six months studying the failure, I'm going to trust the latter.
Unless if you'd like to provide some evidence beyond happening to live in Texas in 2011.
