Expanding the U.S. electrical grid is one of the great problems of today. Reindustrialization necessitates at least 50% growth, and that’s before factoring in the new data centers.
Transferring power between the three U.S. grids requires expensive high-voltage DC infrastructure, but there’s geography, transmission capacity, and regulatory authority in the way. A more fruitful pursuit would likely be creating greater cooperation between local facilities and expanding regional generation.

Hey, everybody. Peter Zeihan here, coming to you from Colorado. And today we’re going to talk about electricity and why the United States is facing real problems in building out its system in anticipation of deglobalization.
First, state the problem. We need to expand the grid by at least half in order to build out the industrial infrastructure that we need for a post globalized world that assumes no data centers. If you want data centers to, now you’re talking about a 75 to 100% build out. So you know a lot.
Now let’s talk about the nature of the obstacles. Electricity. Think of it as a wave. Highs and lows. 60Hz is the frequency that most of the US power grid is on. And the problem is, is maintaining that wobble basically requires a lot of work. And doing it over larger and larger chunks of territory makes it even more work. So the United States system is split into three grids. You’ve got the Western Interconnection, the Eastern Interconnection, and then the Texas grid, and they split roughly along the eastern flank of the Rocky Mountains. And then in the areas around Texas. So, you know, Louisiana, Oklahoma, New Mexico borders roughly; it’s not quite that clean, but that’s roughly what it is. The more territory you can have in the same grid, you know, the more efficient it can be, the more you can back up. And when you get countries like Germany or France like, oh, you should unify your grid like we did. You can’t really do that in the United States because you can’t fit the entire United States in your back pocket. So three grids, other large states do something similar. So I think the Russians have like 7 or 11 grids. If you want to link these together you need an HVDC station, high voltage DC, where you take the alternating current that is in one grid, convert it to direct current, and then reconvert it into another alternating current that matches the wobble of the receiving grid. And of course, you want these to go both ways. So the infrastructure is immense. But even if everyone agreed we wanted to link things together, there’s a couple other problems.
Number one, we don’t have a lot of long range, high voltage transmission systems in the individual grids, much less connecting them. And the further you transmit the power, the more you’re going to lose, no matter how efficient your carrier is. So unless somebody magics up a really low cost room temperature superconductor system, you’re talking about having to ship power halfway around the country to take advantage of any of these interconnections. In addition, where these interconnections are, like I said, the east side of the Rockies or in the areas around Texas, you’re dealing with areas with low population density. So you’re having to go through these zones to get to any population centers. I mean, Chicago is really the largest city that’s close to one of these connections or Houston. It’s a long way from everywhere else. There’s another problem. While we have those three grids, it’s not like those are three coalesced unified electricity systems. Most of the electricity that people use is produced less than 50 miles from where they live. So you’ve got this raft. Hundreds of local power producers, whether it’s co-ops in rural areas or independent power companies like, say, Austin Energy in Austin, Texas. There aren’t a lot of bigger ones. And those that there are say, say, Southern Company in the Deep South have worked very hard to consolidate their zone. And the idea that they’re just going to suddenly allow power to transmit through their system is kind of a bit of a reach. And so if you’re talking about building these HVDC systems on the connectors between the grids, you have to go through huge amounts of empty territory where there’s no good transmission yet in order to go to a population center. And that means you’re crossing multiple jurisdictions on your way, everyone’s going to have their own regulatory structure. So, I mean, yes, politics is part of that, but it’s politics as formed by geography.
So the bottom line is don’t expect to see this anytime soon. Step one is you’d have to break down some of the barriers among all of these various authorities. Step two you then would have to build in long range transmission into the sub grid or the main grids. Only then three, can you talk about building enough high voltage DC converter systems on the edges of those grids in order to meaningfully move power among them. So this is a problem that will last until there’s been a significant change in how Americans view local authority versus federal authority or, and or, until there’s a significant change in how you can move electricity writ large. It’s not that it can’t be done, but this is not the low hanging fruit in the American power system. That comes from new technologies like combined cycle natural gas. Maybe, maybe, maybe if it works, small modular nuclear reactors. But really a decision for jurisdictions that are adjacent to one another to share resources, do that first. Then we can start talking about the hard stuff.
