The AI buildout has a grid problem. And the grid problem has a math problem.
On a recent episode of SemiAnalysis’s Something Else Weekly, Jordan Nanos and Robert Boswall surfaced an argument that deserves far more attention than it’s getting: America’s largest grid operator may be burning ratepayer money at scale — not from corruption, not from underinvestment, but from a modeling error.
That’s a specific and consequential claim. Here’s the structural read on why it matters.
The Argument
Nanos and Boswall’s position — as expressed in this episode — is that PJM’s modeling approach is generating a systematic error. The result, in their framing: $12 billion in unnecessary costs landing on US ratepayers who have no visibility into why their bills reflect that burden.
“Money that they don’t have to waste” — the phrasing is precise. This isn’t an argument about necessary costs of transition. It’s an argument about avoidable costs from an analytical failure.

In our Permission Layer framework, the grid operator functions as an invisible regulatory chokepoint — the entity whose models determine what gets built, what gets priced, and who pays. When that model is wrong, the error doesn’t surface as a line-item. It surfaces as higher bills, stranded investment, and misallocated capacity.
The datacenter and AI infrastructure boom makes this load-forecasting problem sharper, not softer. More demand volatility means modeling errors compound faster — and at larger scale.
Why This Surfaces Now — FourWeekMBA Analysis
The AI infrastructure conversation has focused almost entirely on chips, models, and data. Relatively little analytical attention has gone to the grid layer that powers all of it. If the argument Nanos and Boswall are making holds up to scrutiny, the story isn’t just about one operator’s methodology — it’s about whether the institutions governing electricity markets are calibrated for a world of massive, irregular datacenter load. That’s a structural question, not a cyclical one.
The Bottom Line
Grid modeling is not a boring back-office problem. If the SemiAnalysis argument is right, it’s a $12 billion tax on US households — imposed not by policy, but by analytical error. The AI buildout will stress these systems further. The question worth asking: who is actually auditing the models that set the price of electricity?
