So they rely upon the external grid and pass the externalities involved in being being able to dispatch power when you flick the switch to some non-renewable plant elsewhere. Gotcha.
The grid isn't one big national national. Our national grid is a bunch of separate grids. Since San Antonio is on the middle of Texas it is on the Texas Interconnection manged by ERCOT [1].
Here's information on the overall grid generation where if you look at the fuel mix report for 2020 YTD you'll see 26% is Wind so overall it is also above 20% [2].
