During several days of the heat wave this summer ... ERCOT was obliged to request that Texans cut back on their use of electricity during the late afternoon and early evening hours [to avoid blackouts]
The problem is that Texas has invested heavily in wind and solar power... [and] during several days in August, the wind was not blowing enough for Texas’s wind farms to operate at optimal capacity. At the same time, as the sun went down, Texas’s solar arrays gradually stopped providing power as well.
TX is in a unique place since their grid is not interconnected.
The fix for Texas is to stop acting like Texas, which is challenge level: IMPOSSIBLE.
Regulation to ensure the quality of life for its residents would help a great many things, however greed and hubris often get in the way.
