Wind power output in Texas is trending down even as wind generation capacity increases

The inherent unreliability of wind power is highlighted by the recent experience in Texas.
I have written extensively about the intermittent nature of wind power (here, here, and here), highlighting that the only way wind power has survived and continues to increase is through federal tax subsidies. Wind proponents have long argued that the intermittent nature of wind is offset by over-building wind generation, based on the theory that the wind is always blowing somewhere.
The reality that the wind is not always blowing where it is needed, even over very large areas, is highlighted by the fact that wind power in Texas has been declining.
Total wind power generation in January 2024 was less than in January 2023. According to Reuters in an article published on February 16, 2024:
Cumulative wind power output in 2023 was 4,500,000 MW, compared to 4,400,000 MW in 2022, LSEG data shows. That 2.4% climb in annual wind output is less than the roughly 3% rise in wind generation capacity within the system in 2023, according to ERCOT. Unusually low wind speeds were the main cause of the stunted growth, with output in April, May and June all falling sharply from the prior year totals.
Adding insult to injury, this decline in wind power occurred even as total wind generation capacity increased by a staggering 28% from 356,000 megawatts (MW) to 455,000 MW in January 2023, according to data from the Electric Reliability Council of Texas (ERCOT).
So much for the fallacy that the wind is constantly blowing somewhere. Wind farms in Texas cover thousands of square miles of south Texas, West Texas, and the Texas Panhandle, and, yet total wind power generation declined year-over-year:

As is always the case on all U.S. power grids, natural gas came to the rescue to offset the decline in wind power:
