CPS Energy, serving the San Antonio, TX metro is already above 20% renewable[1] and its rates are very low, to the point San Antonio is a preferred data center location.

- evgen 6y agoSo CPS energy and it’s grid are disconnected from the rest of the national grid and have no reliance upon external sources to ensure dispatchability? Cool. Would love to hear more about how they managed that trick.
- bretpiatt 6y ago> Cool. Would love to hear more about how they managed that trick. 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].
