How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Brian Janous on measured tape to publish a rate. This says nothing about how they speak.

Insight
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 …”
Brian Janous Dec 5, 2024 ▶ 28:38 Explaining the 'Watt-Bit Spread'
Insight
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.”
Brian Janous Dec 5, 2024 ▶ 36:20 Explaining the 'Watt-Bit Spread'
Assertion Supported
Janous: Full-stack data center CapEx, including GPUs, costs $25M per megawatt.
“The cost of a data center today in terms of the full stack CapEx deployment all the way through GPUs is about 25 twenty-five million a megawatt or twenty-five billion a gigawatt”
Brian Janous Dec 5, 2024 ▶ 39:29 Explaining the 'Watt-Bit Spread'
Opinion
Janous: Utilities should require proof of capital for gigawatt grid requests.
“If you're saying you're going to build a gigawatt data center, Or you're holding on to a gigawatt of power in a queue position. At some point, you need to be able to point to billions of dollars of capital that you have access to build out that infrastructure.…”
Brian Janous Dec 5, 2024 ▶ 40:45 Explaining the 'Watt-Bit Spread'
Insight
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.”
Brian Janous Jun 13, 2024 ▶ 6:32 Under the hood of data center power demand
Insight
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…”
Brian Janous Jun 13, 2024 ▶ 11:19 Under the hood of data center power demand
Assertion Supported
Janous: AEP's data center demand forecast surged 275% in five months
“If you go even back to January of this year, PJM had Roughly four gigawatts of anticipated data center demand for AEP by 2030, and by May, AEP revised that up to closer to 15, in just five months, right?”
Brian Janous Jun 13, 2024 ▶ 15:27 Under the hood of data center power demand
Opinion
Janus: Standard 48-Hour Diesel Backup Is Probably a Data Center Relic
“I will say that backup is probably a bit of a relic because when we first started building these data centers, 15 years ago, most of them were relatively small. They were five or 10 megawatts. They were connected at distribution voltage. So the standard was pu…”
Brian Janous Jun 13, 2024 ▶ 19:09 Under the hood of data center power demand
Assertion Partly supported
Janus: Every New Dublin Data Center Must Install On-Site Gas Generation
“So now every new data center in Dublin is getting a natural gas generator behind the meter so it can be flexible and, you know, avoid that contribution to system peak.”
Brian Janous Jun 13, 2024 ▶ 31:19 Under the hood of data center power demand
Assertion Partly supported
Janous: Data centers spurred massive civic investment and job gains in Quincy
“There was a fantastic story just in the last week about Quincy Washington building a fifteen million dollar aquatic center and they have a hundred and fifty million dollar state of the art school and their unemployment rate has gone from like 29% to six percen…”
Brian Janous Sep 3, 2026 ▶ 5:45 What comes after the data center backlash?
Disclosure
Janous: Cloverleaf refuses to sign NDAs with government officials
“I mean, for us and for Cloverleaf, we don't sign NDAs with government officials. Like, we don't think that's good practice.”
Brian Janous Sep 3, 2026 ▶ 9:21 What comes after the data center backlash?
Insight
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.”
Brian Janous Sep 3, 2026 ▶ 11:23 What comes after the data center backlash?
Assertion Supported
Janous: Electricity prices did not rise for 100 years during grid expansion
“Electricity prices did not go up for a hundred years as we massively expanded the grid.”
Brian Janous Sep 3, 2026 ▶ 21:01 What comes after the data center backlash?
Prediction Open · timeframe Dec 2030
Janous: Terrestrial data centers will remain the vast majority through 2030
“I just look at the pie of total data centers by 20 30 and pick your date in the future. I'm a big believer of terrestrial data centers are still going to be, like, the vast majority of the way we build data centers. Like, I just don't, I'm not sure how much it…”
Brian Janous Sep 3, 2026 ▶ 37:16 What comes after the data center backlash?
Assertion Open · timeframe Sep 2028
AI training data centers are beginning to abandon backup generators
“I think with some of the AI training sites, we've seen it's more of a move away from backup generators.”
Brian Janous Sep 12, 2025 ▶ 7:17 When to colocate data centers with generation
Opinion
Permitting gigawatt-scale diesel backup generators is nearly impossible in most markets
“I think for those kind of sites, it would be very difficult to Permit that scale of diesel generators in most markets.”
Brian Janous Sep 12, 2025 ▶ 8:29 When to colocate data centers with generation
Insight
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…”
Brian Janous Sep 12, 2025 ▶ 18:56 When to colocate data centers with generation
Assertion Supported
Janous: Data center developers can enter utility queues for just $10,000.
“And some of them are big tech companies, and some of them are just two guys with a truck that decided they were going to be data center developers, and they go get a queue position, and they have to pay 10,000 dollars, that's it, to get in the queue.”
Brian Janous Dec 5, 2024 ▶ 12:47 Explaining the 'Watt-Bit Spread'
Insight
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.”
Brian Janous Dec 5, 2024 ▶ 26:18 Explaining the 'Watt-Bit Spread'
Assertion Supported
Janus: Microsoft's energy demand grew from hundreds of megawatts to gigawatts
“Over that decade, we had gone from a baseline of, you know, a couple hundred megawatts, and we were growing at a relatively rapid pace, but that's also kind of a small denominator. So the incremental tranches every year that we had to go procure were measured …”

Insight
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…”

Assertion Supported
Janus: Data Centers Account for Nearly 20% of Ireland's Electricity
“It's almost 20% of the entire country of Ireland's electricity are data centers, and they're almost all in Dublin.”
Brian Janous Jun 13, 2024 ▶ 31:00 Under the hood of data center power demand
Assertion Supported
Janous: Land represents just 1% of a data center's 15-year total cost.
“I mean, on a total cost basis, you know, over a fifteen-year period, and, you know, TCO is the way we think about it in the world, land is about one percent. Of the cost to operate a data center. You know, the full stack with servers and everything.”

Belady: Microsoft Data Center Team Had No Dedicated Power Specialist in 2010
“When I was running the data center team back in 2010, 2011, we didn't even have a power guy. Right? It was a non-issue, and it took me a year to justify hiring a power guy, and that guy was, and I think you interviewed him, was Brian Janis.”
