> In 2011, Texas was hit by the Groundhog Day blizzard between February 1 and 5, resulting in rolling blackouts across more than 75% of the state… Following this disaster, the North American Electric Reliability Corporation made several recommendations for upgrading Texas's electrical infrastructure to prevent a similar event occurring in the future, but these recommendations were ignored due to the cost of winterizing the systems.
> Unlike other power interconnections, Texas does not require a reserve margin of power capacity beyond what is expected. A 2019 North American Electric Reliability Corporation report found that ERCOT had a low anticipated reserve margin of generation capacity and was the only part of the country without sufficient resources available to meet projected peak summer electricity demand.

If I hadn't been reading headlines I wouldn't have even known about the 2011 blackout, and I was definitely here for that. Things were pretty much normal for everyone around me and friends around the state (Houston, Austin, DFW, Lubbock, San Antonio, etc). The Superbowl even went ahead in AT&T stadium. It really wasn't as big of a deal as a lot of internet commenters seem to act like.
I lived in Texas and we never got rolling blackouts for this. We didn't hear about it from family and friends in every major Texas city. Maybe this means 75% of the state by area rather than population? We just didn't drive because much of Texas isn't set up to clear roads and, more importantly, few of our drivers know how to deal with snow and so most get very unsafe to drive around.
The report your wikipedia article cites for 75% says this: "In the case of ERCOT, where rolling blackouts affected the largest number of customers (3.2 million), there were 3100 MW of responsive reserves available on the first day of the event, compared to a minimum requirement of 2300 MW." So an eighth or so of Texas' ~25 million population in 2011.
