If route A is down, route B is used.

This is redundancy.

Texas only has route A.

That is the issue. Power cannot come from anywhere else than route A because there is no connection to the national grid, route B.

This doesn’t prevent last leg localized power outages, but it does prevent the widespread grid wide failures Texas regularly experiences.

But you don’t want to hear this, so go buy a diesel generator instead and enjoy being independent.
