Texas is connected to the Eastern (Florida to Canada) grid, the Western (Cali to Canada) grid, and a Mexican grid not part of the US/CA system via tie-ins. It is the only state in the continental US with it’s own grid, which was not a smart decision (cough cough feb 2021). The most outrageous part was that they could have bought power from Mexico, east, or west and import it via those tie-ins during Feb 2021 but chose not to. Power was out for millions for over a week. Fuck Texas. Fuck CenterPoint Energy.

Additional Information: Besides Texas, Quebec and Alaska have their own grids as well. Alaska is the only grid without any tie-ins.
