AC transmission absolutely does work over large distances. It’s just not a point-to-point system.

Imagine four cities in a row, all connected with AC. City A generates extra power, which gets sucked up by city B, whose power goes to the next city down the line, to city Z.

Sure, it’s not actually that simple, but when was the last time NY literally had no power? They benefit from being highly connected.

TX is paying for being isolated.

Their handful of DC interconnects do not have the capacity to power their mini grid. They’re short 35GW of generation, and I assume the DC ties are at capacity.

Do you not remember the blackouts of 2003? Multiple entire states went dark for hours, and the “highly connectedness” was a huge part of the problem. The only reason it wasn’t even worse is specifically because grid isolation stopped it from propagating further, just like what’s happening here.

Just look at the first image on the Wikipedia page, showing the extent of the blackout. This is far smaller than the footprint of the eastern interconnect. The control software at the time made some simplifying approximations which left the grid vulnerable to problems cascading between operators. I do not think they have quite the same problem anymore.

There is another problem here. Texas generates as much power as the second and third states on the generation list. The outage Texas had would have sagged most of the US.

Separate grids are great for other kinds of emergencies, if we get a big solar flare then the splits save each grid.

We need a east to west DC long distance interconnect to haul power across the country.
