About The Grid Letter
Texas electricity just became a different market.
Not because of a policy change or a weather event — because of something that doesn’t reverse. The same forces driving AI adoption are driving permanent, structural demand onto the ERCOT grid. Data centers, compute infrastructure, and the businesses that depend on them don’t shed load. They add it. Every quarter.
What happened to businesses that ignored the internet in 2001 is the same thing that will happen to businesses that ignore their energy costs in 2026 and so on. The underlying market has changed and the bills will reflect that whether you’re paying attention or not.
The Grid Letter exists for anyone trying to understand what that means.
That includes the business owner watching their electricity costs climb without explanation. The entrepreneur building inside the energy space. The investor tracking infrastructure plays in Texas. The student who wants to understand ERCOT before anyone else their age does. And the curious Texan who just wants to know why their bill looks the way it does.
Texas runs one of the most complex, consequential, and misunderstood power grids in the world.
We cover it. The pricing dynamics, the demand trends, the grid constraints, the procurement timing, the policy shifts, and the structural forces underneath all of it. Each issue translates what’s happening in the market into something you can actually use, regardless of where you’re standing.
No jargon. No filler. Just the market, made legible.
