Janus: Chip efficiency gains will not reduce AI data center power demand
“If let's say Meta, for instance, finds a piece of land or a point on the grid where they can pull three gigawatts, Of power on one location. And then the next day, NVIDIA comes out with a chip that's twice as efficient. Is Meta going to build a 1.5 gigawatt da…”

Janous: Taking data centers off-grid prevents broader electricity rates from decreasing
“It's fine micro, but I would even say, I mean, if you believe that a larger denominator is actually good for lowering electricity rates over time, it's actually negative in that you're taking that denominator off the grid.”

Transmission lines act as direct substitutes for local baseload power generation
“The transmission line itself is a substitution for baseload power, because if you can move more power over more space, you are Reducing the need to have to generate that power on the other end of that congestion. So in that sense, transmission and generation a…”

Janous: Securing electric power creates a defensible competitive moat in AI.
“And so not to mention the fact that the ability to acquire and collect those electrons then in some ways creates a moat against other folks that would want to try to do the same thing. So the more electrons That you can get a hold of, especially in the AI worl…”

Janous: AI companies pay huge speed premiums because base infrastructure is cheap.
“The cost of the base infrastructure for my end product is actually really low. And when I say base infrastructure, I talk about land, you know, power a data center shell, you know, those things are relatively inexpensive. In the grand scheme of operating, you …”

Janous: Continuous data center loads benefit grids by improving infrastructure cost recovery.
“Having more data centers on the grid is good because they use power 8007 60 hours a year. So there's more cost recovery for more infrastructure in more hours if you have more data centers.”

Janus: AI technology is advancing faster than electric utilities can build power
“The problem we were going to have was going to be whether we would have enough power to support this technology that was moving at a pace that, as you know, moves way faster than the electric utility industry.”

Janus: AI training latency constraints require single-site gigawatt data centers
“Because those training models are in and of themselves a big machine, and so you can't, and this is not my forte and my area of expertise around the actual architecture inside of a training model, but my understanding of sort of the constraints there is that y…”

Janous: Data center industry fails by fighting emotional backlash with facts
“I think the industry has tried to attack this with facts. And really miss the emotional resonance of, like, people just aren't happy about this stuff right now.”

Utilities evaluate data center interconnections on peak capacity, not annual energy
“The problem we're trying to solve here is not that I need a 24 seven generation to match a 24 seven load. It's that I need to solve for The summer peaks and the winter system peaks in order to connect alone. That's what a utility does, and I think it's a, I th…”

Janous: Power capacity in 2027 is worth significantly more than in 2032.
“The value of a megawatt in twenty-twenty-seven is worth more than a value of a megawatt in twenty-thirty-two, because there's an assumption that by twenty-thirty-two, power will probably be more abundant, that will have sort of run through this cycle.”

Janus: Cloud Apps Cannot Seamlessly Move Regions During Data Center Outages
“I think people have this sense of the cloud as really being this sort of ethereal thing, and applications can just move around, and if one data center goes down, then, well, you can just move everything to another data center. That's not really how it works. W…”
