So why is there an end of life for your battery?
8:22
There really isn't.
8:22
If you operate them correctly, you can operate them almost indefinitely.
8:27
Everything that we build as far as the plumbing, the tanks is all HDPE or plastics.
8:32
The stacks have a life because the membranes degrade a little bit, but you can swap stacks just like you'd swap cells on a battery and keep going with it.
8:39
They last probably 25, 30 years.
8:43
If operated correctly, you can potentially get them to 40 years.

And we have a wave of inference demand coming around all the big cities.

SunCast is also brought to you by NextPower

The grids can't operate fast enough to be able to respond to the volatility they're experiencing.
0:12
They're creating a tremendous amount of harmonic distortion issues, and when you have that kind of power volatility, you can trip air breakers at substations.
0:18
It's reacting faster than even the generation assets can keep up with.
0:22
The fastest generation asset on the planet right now is natural gas, is gonna be a recip at about 25 to 30 seconds.
0:29
We're seeing power volatility where you're getting multiple 30, 40, 50, all the way up to 80% swings at the total size of the data center.
0:37
So you're talking gigawatt scale, you could have 300, 500, 800-megawatt swings multiple times per minute.

17:44
Yeah.
9:59
Okay.
9:59
The thing that everybody's talking about is how long it takes to interconnect.
10:02
Nobody's talking about what happens when you actually turn them on.
10:05
And I, I, I think that obviously the, the, as you see gener- you know, buying generators, there's a, a long lead time on getting gen sets, um, and you're seeing some deals come and some deals go.
10:18
What you're seeing, it, it was no different before data centers were here.
10:21
It was the battery craze, right? Like interconnection queue for people that went and had land, and they could get power on land to interconnect and put a battery in, you know, it was like half the projects would never see the light of day, but everybody was connecting because if they could get the power to it, they could then flip it to a developer that would build it.
10:38
I think you're seeing a very similar, at, at least we've seen this, where lots of people that have, you know, rural lands, and there's all of a sudden a big power line that comes through their land, go, "I can build a data center here." And, and, you know, it, it, they, they might have been able to get $5,000 or $10,000 an acre, but if they can get a large load interconnect, they can get $100,000, $200,000, $300,000 an acre for the same land.

12 MINS LATER

23:23
Yeah.
58:45
What does the domestic manufacturing landscape look like?
58:49
Our first state-of-the-art factory will be open in Q2 of this year.
58:54
We then plan to open two gigafactories shortly thereafter with the plan to break ground in 2026.
59:01
They're multi-gig factories to be able to deal with this demand.
59:06
They're right now in planning phase because we're working through the incentives with the state.
59:12
for a lot of these data center campuses where they're starting to phase in their projects.
59:16
A lot of that is just AI demand and we have other applications for it as well, but that's helping to drive the demand for what we're doing.

7 MINS LATER

Are the problems we've expressed over the last hour a short-term, medium-term, or long-term reality for the industry?
