Articles that try to compare Texas with California almost always miss that California is not it's own grid.

Power in California is from the Western Interconnect, which is regulated by WECC.

Power on the Western Interconnect is only 8.7% solar and 10.4% wind.[0]

Texas in the same year was 7% solar and 24% wind.[1]
