TFTC: A Bitcoin Podcast - Bitcoin Mining in ERCOT | Brad Cuddy, Center of Hash E007

Episode Date: September 9, 2025

Brad Cuddy, Director–Energy Operations at Cholla, Inc., discusses the benefits that bitcoin mining is actively providing to the ERCOT grid, why deregulation and real-time pricing in ERCOT is creating a unique opportunity for bitcoin mining to innovate in Texas, how bitcoin miners compare to AI datacenters from a load perspective, and why bitcoin load and batteries are complementary tools to help balance the grid. https://x.com/_bradcuddy_ https://chollainc.com/ https://www.linkedin.com/in/bradleycuddy/

brad welcome back to austin parker good to be here man um last episode with pierre we went real deep on the difficulty target and the difficulty adjustment um today we're going to talk about mining and ercot ercot generally grid mining but also talking about the broader market and how bitcoin mining fits into that so we'll inevitably get deep but appreciate you being here and recording got brad cuddy from cholla inc what does the hat say never stop exploring never stopped exploring yep we've got to figure out uh if that was a gideon pal original or if it was passed down but of that i shot him a text no answer yet so not yet dbd all right we're going to dive right in um to an actual example of how bitcoin mining is interacting with the

ercot grid in terms of winter storm and around scarcity events and then we'll kind of come back up for air to talk about how different levers why things are happening but there's a chart that urquhart had put out during winter storm heather in january of 2024 that the the storm spanned two or three days and the the price of power effectively increased from you know fifteen dollars a megawatt hour to on a log scale looks like seven hundred fifty dollars to thousand dollars a megawatt hour and approximately 1.1 gigawatts of power specifically large flexible load came offline the power price came back down basically peaked came back down another scarcity event this time almost 1.6 gigawatts of large flexible load came offline

and then there was a third peak and similarly so talk about the actual incentives that are driving that and what might be happening to create a scarcity event in ercot during the winter and then how ercot helps manage that and how bitcoin miners play into it yeah i think this is the this is really hitting on the the beauty of bitcoin mining in ercot it's a completely economically rational responder to a price signal you can see there that they have a line drawn at what is it 120 megawatt hours it's like a assumed average of break-even price right 122 megawatt hours which is what ercot had calculated as what they viewed bitcoin mining's break-even being based on a s19j pro which is interesting that someone at ercot is doing this math presenting

this to ercot yeah when evan neal was at ercot he was he was in the weeds he's a bitcoiner so we had one of us in there he's since left but i digress um so what you can see is that the pink highlights on the graph those are ercot issued conservation appeals those are alerts that are coming out via your retailer or your queasy or even like to a residential uh user on your app and like hey looks tight we don't know if we have enough generation to serve the projected load so if you could you know you know not use as much load that would be appreciated so and this is when in the winter everyone's running their heaters yes freezing temperatures maxing it out right and temperatures are going down so it's likely at some point early in the like overnight early

in the morning right it it's it's likely yeah overnight early in the morning uh we have that in the in the winter time it'll peak in the morning time sometimes you'll get an evening peak too but the load curves look completely different on uh on uh winter versus summer but here what you will what you'll see is um the blue which is the total large flexible load start to step down as that price line, the black line starts to go up. So the miners are doing this purely off of like an economically rational decision. Like if you're making 120 bucks a megawatt hour and power costs $200 a megawatt hour, you're losing money. It's a quick way to go out of business. Like you do not want to be doing this. There's a potential to have some

layered on hedges or like be committed to an ancillary service. So you have to keep your load on. I don't want to get too nuanced here, but the Bitcoin miners are responding to the price. The price is a signal of generation scarcity. As generation becomes more and more scarce, it goes up and up the generation offer curve, and it settles at the lowest price generator that clears the market. And so in this situation, there is less and less generation. they're um likely hitting the ORDC operating reserve demand curve that's just that's a long string of ERDC sorry sorry uh ORDC yeah operating reserve demand curve and so that basically when ERCOT gets to I think it's two or three thousand megawatts worth of reserve capacity left meaning

late in gen that can turn on like when it's when load in gen is within two thousand dollars they start increasing the prices to send the right price signals to have every generator turn on whether it's like this old steam generator whether it's a marginally economic coal unit like they're sending the price sky high and then hoping that the market responds and you know acts rationally in an economic basis and bitcoin money does here and so on the other side on the other side exactly yeah because the price is going up and nobody wants to eat a thousand or two thousand dollars a megawatt hour it's a it's a very quick way to to lose money so if someone is looking at the chart when this winter storm starts there's about 2.2 gigawatts of large flexible load which

in your mind is that virtually all bitcoin mining yes yeah practically speaking yeah there is and We'll talk about why that's the case, but just wanted to touch on this now. As the market price started moving up before the first conservation notice, about 500 megawatts had already come offline. and then as the price ramped further another one gigawatt of power came offline and a bitcoin a bitcoiner would look at that and say that's that's bitcoin mining helping the grid but this interesting note from from ercot which is basically saying not all large flux but not all not 100 came offline but making making that point right Um, but then basically the market price comes down, the large flexible load comes back up to

like 1.9 gigawatts. And then the next time there's a conservation notice 1.6 comes offline. Um, but just talk about the, um, the relationship there. Like it's not a, it's a request a hundred percent of the market right even like grandma and grandpa at their house this is a this isn't a notice that's going out just to bitcoin miners correct yeah this is is uh this is an you know urquhart wide notice conservation appeal and you can even see on that third section there wasn't even an urquhart conservation appeal which is indicated by the pink but the bitcoin miners responded to the price anyways and it's interesting because the the price if you if you look at the price on that third peak goes higher goes higher but there's not the conservation no so what would

is that because they have more generation available you know i'm not sure on this specific um that specific peak it could been um they were forecasted a warmer temperature and it actually was colder so they didn't have the time to put out a conservation nobody's going to read it at three o'clock in the morning if this is like a morning hour peak um or it could be that there's there's more to system reliability than just price um so they might have felt that they had enough operating reserves uh to to satisfy enough ancillaries or whatever it might have been um but there is there is more to reliability than just price and then the last thing because i have a few of these charts we won't bring the other ones up but so to lead into the broader discussion

it is relevant that ercot is looking at this and tracking it and paying attention to not just what's supposed to happen in theory but what's happening in practice but that if we looked at a similar analysis that ercot had done in 2022 there was approximately 1.5 gigawatts of large flexible load around a scarcity event on the grid to start and then in 2023 1.9 gigawatts and then this example that we were talking about from september 2023 to january 2024 2.2 gigawatts so this amount of large flexible load continuing to increase approximately how much bitcoin mining is on grid in ercot today would you estimate i think the lfl large flexible load estimation is right around three and a half gigawatts uh lfl's

the classification is greater than 75 megawatts there's also a lot of miners sub 75 megawatts whether it's transmission level but just on a 50 megawatt interconnect or distribution level like that we are too so if you add all of that up i think we're probably in the high three gigawatts maybe low four gigawatts and to put it all into perspective total system-wide peak load i think is 85 or 86 gigawatts. So it's a significant portion. Is that fairly consistent between the summer peak

and the winter peak? Or is that 85, 86 gigawatts of power being demanded summer peak? Do you know? That's the summer peak, but we are shifting towards most likely to being a winter peaking system.

Interesting. And then, so to transition this into a more general conversation, talk or what in your mind allows bitcoin mining to be flexible when other sources of demand for power on a grid system are not and how that benefits the grid yes for the first part um you know every other industrial electrified process on the grid has electricity plus some process equals some widget or output steel aluminum whatever it is sold for dollars so

there's like because of the added complexity the added workload you know people staffing all like raw materials um if you don't finish a smelt maybe it doesn't go all the way through and you have to throw something away. Bitcoin mining, we have no customer. We have no output besides money. We're directly transferring electrons into money. And because of that, we have the purest, most rational price behavior and response that there is. And how that benefits is what you saw there, right? Price goes up. Bitcoin miners, as an economically rational consumer of electrons, will respond to the price as long as the incentives are aligned. And that's why I think ERCOT is so great because you can, in the deregulated energy-only market,

participate in this. And that's why you saw so many miners flock here. And what does it mean for ERCOT to be deregulated? And how does that compare to other grids in the United States? um so what's what's still or still regulated in irka is the transmission and distribution companies what is deregulated is the generation generators and then the retail side like that's why texans have retail choice like you can go shop around for your electricity that's part of the deregulated um movement that came in like i think the late 90s early 2000s um so because of that like you have the um the access to this real-time market and the day ahead market

that urquhart has created in their energy only market and so is it the fact that there's a real-time price that that real-time price doesn't necessarily exist in other grids because i think if i'm understanding correctly the fact that the real-time price exists and it's being communicated to all of the the market at any one time that allows a purely economic actor like a bitcoin miner who again doesn't have a widget that they're producing or a manufacturing plant that's running or a hospital that has patients or a grandmother grandfather in freezing weather to to respond because they have the pricing but is there something about ercot that has you know because i consistently hear the term real-time pricing does that not exist in the same way in other

grids that makes ercot somewhat unique and i'm not an expert on like kaiso pjm all these other grids i don't know for certain on their real-time pricing but i also don't know if like as a consumer as a bitcoin miner consumer of electrons if you could have access to that that real-time pricing so i think that's really what ercot has different is like the ability as a bitcoin miner to access that that real-time pricing and respond economically whether it's to the load zone pricing or whether it's to the node pricing and then as we've seen the large flexible load increase so from 2022 at 1.5 gigawatts september 2023 1.9 gigawatts january 2024 2.2 and now estimating between 3.5 before how does scale factor in to

not the bitcoin mining operation itself but the ability to have more power come offline at points where there is scarcity relative to generation coming online. Right. I mean, naturally, as the amount of Bitcoin mining load increases on the system, it gives you more flexibility.

You know, four gigawatts of load that is able to turn off on a price signal is a massive boon to the system operator. you know what what they don't want is it all turning off at once and yeah you know we have a responsibility as bitcoin miners as stakeholders in ercot to to be good stewards to like follow ramp rates to act responsibly and economically rationally um but it's it's only good you know because of how much intermittent generation is coming to ercot whether it's wind because the wind belt intersects North Dakota to West Texas, and then the solar belt goes from California to

West Texas. We have a ton of intermittent generation. For the most part, it was stranded. For a long time, it was stranded. I think over the last eight years, so pretty much since the inception of Hoddle Ranch when Gideon went out to West Texas, and this isn't just Bitcoin mining, it's some oil and gas load, but the load in West Texas has increased, I think it's at least threefold. Load is demand for power. Load is demand for power instead of generation. The generation was already going to West Texas because that's where the wind and that's where the solar is, where Bitcoin's a location agnostic consumer of that load. It doesn't need to be close to a city center, it goes where it can. It goes where it wants. Where power is Jesus.

Power, exactly. And so if you have all this generation siding out somewhere that doesn't really have that much load, it was a natural incentive created by the market to show that Bitcoin mining, if you can curtail, if you can respond to price, West Texas is the place to be. And we've seen that over the last eight years, three times, the total load in load zone West, which is a classification of, you know, all the way to like Pecos, Pio, Monahans, Midland, basically the entire Permian and Delaware Basin is in low zone west all the way down to Big Bend and then over to Abilene, I believe. And so to have the frame of reference, So you mentioned that at peak, like peak, peak demand might be 85 gigawatts of power and Bitcoin mining might be four gigawatts that if it were only a hundred megawatts, the ability for the market to feel an impact of that, to solve a problem is lower.

but what's functionally happening and again power has to get to specific points on the grid that it's just to use a rough example everything's more complicated than this that as demand is going from 81 gigawatts to 85 gigawatts four gigawatts coming offline versus the highest cost generators coming online is what helps mitigate maybe that price ceiling that the entire market would have to bear. And so as Bitcoin mining represents more, at least in peak times, it can help solve a larger problem for greater scarcity events. Correct. Because we're not on when the price is going high like 122 dollars a megawatt hour is 12 cents a kilowatt hour most people's delivered power in the entire greater united states is greater than that price where all pretty much

all bitcoin miners are off right and this is in this was in january of 2024 hash rates increased significantly so that that perceived break even or marginal break even for bitcoin miners might actually be lower six cents or seven cents a kilowatt hour today who knows what it is but um that it that it's not static two two concepts and we'll talk about one of them first you talked about ramp ramping down and ramping up somebody might generally understand bitcoin miners responding to price signals but urquhart's the electricity reliability council of texas that talk about the actual challenge of why having to balance supply and demand is not just a market function but

a reliability function of the grid itself and to go into a little bit of detail when you're talking about the importance of how say a large load might ram down or up to be a uh not a steward but a good market participant right ever since winter storm yuri which every texan remembers urquhart's been in the in the limelight as much as they don't want to be but for those people who are not familiar with winter storm yuri that was it was actually before my time here it was 2021 one i believe it was a cold snap that lasted something like nine days um and there was various reasons for uh for it but price price went to the cap at that time it was nine thousand dollars a megawatt hour um generation was unable to black star pipelines were freezing wasn't sunny

so the solar wasn't producing no wind it was like a black swan through and through but uh it ended up with you know a lot of rolling blackouts and when people lose power and it's super cold and you can't turn on the heat uh you know our young and our old are are susceptible to that and so there was there was death that was associated with it it was it was top of mind for everybody um and that just highlights how important it is for ercot especially because it is um an island and system and i'll just explain that real quick yeah if you could uh so the entire eastern part of the united states is under the eastern interconnect uh it's all electrically connected the entire western part of the united states you know every everywhere from

washington state down to like new mexico over to colorado and maybe like the bordering nebraska whatever uh is is electrically electrically connected so they have all that generation all that spinning mass they've got nuclear here you've got solar there like there's there's a lot of support from the entire grid you know like okay like how much could it actually support it's so far away well like electrons travel at the speed of light and like not to get too technical like they don't actually travel blah blah blah but it's it's very quick and so with all of that system-wide generation all that system-wide load uh the interconnect can support fluctuations bolted fluctuations generator trips load trips just because of its inherent size ercot is completely

electrically isolated it is essentially you could imagine in an island it it has like small dc ties like direct current that's what i my understanding was there were some ties but i don't know enough to know how or to what extent yeah so a couple gigawatts of dc but the thing is our grid doesn't run on dc it runs on alternating current you know it's three magnets spinning around generating current it's like that spinning mass is what generated our electricity pre wind and solar um and so that creates the alternating current that is is like the heartbeat the 60 hertz of our grid uh so the dc doesn't help support that so it gives us a little bit but it doesn't give us the uh the support um and so why why ercot was so unique is because of that islanded situation

like it has to rely on itself and so because it has to rely on itself it needs to prioritize reliability right you said it's it's in the name um i got in the weeds and i forgot a little bit the question but so like talking about the function within ercot of why or how loads how they ramp up or down from an actual grid reliability standpoint is a concern beyond just price volatility and bitcoin miners responding to price to come off that um how they do that right is consequential but just talk about that concept and i and i think something to highlight too is that you know bitcoin mining as a load might get a lot of criticism or like oh it goes off too quick like it's not following a ramp right or it's um you know previously the conversation

was this is even real like is this just going to go away um i don't i don't think we get enough credit because we are able to like very very fine-tune our load most load that is on the grid is is like heating load it's totally blind to ercot they have no visibility into this uh bitcoin miners if they you know qualify as a controllable load resource they're able to submit their load curve into into ercot so they have complete visibility all generation submits a their their um generation stack into the curve on the flip side submitting the load side into into the curve allows orcot to match help a system reliability um ensuring that the frequency is in that and it has the range of 60 hertz it has to be within a very tight band at all times

correct yeah and like that would be that would be supported via um ancillary services like fast frequency response regulation up regulation down it basically will request say frequency goes too high meaning the generators are spinning too much you need to bring load up bring the frequency down say frequency goes too low means um not enough generation on the system you bring load match. And so that's something that Bitcoin miners are participating in. However, batteries are able to do it pretty well. So they have kind of eaten up most of that market. But Bitcoin miners are in other services like Nonspin or ERS. And these are like all, basically ERCOT has, because there's no capacity market. It's just energy only. They have some different ancillary demand response is

basically what this gets lumped under. But the technical term is like an ancillary market. The ancillary market has different products that can be bid into as a load or as a generator. And so Bitcoin miners can provide these ancillary services to ERCOT. And this is, For example, the controversial riot filing in September during an EEA event, they committed their load to be an ancillary service. They said, we will stay on and we will only be curtailed when you tell us. So they ignored the price. You have to have a hedge to do this. Otherwise, it's not economically rational.

but they use their bitcoin mining as a way to support grid frequency or voltage or whatever it was and by doing so they are paid the thing is like the the bucket of ancillary services is it's like it's it's on a bid basis they they clear as the lowest bid and so if riot was called as that ancillary service that means that they were one of the lower bids so as batteries and bitcoin mining reduce the like the cost to bid into the ancillary services all ercop stakeholders benefit from it right because if i'm interpreting that correctly because if they weren't there somebody with a higher bid correct it would have been a steel mill or a heavy industrial that wouldn't have that uh fine nuanced control of being able to like step down you know 20 of your

load every minute over the five minutes to get down to certain targets right like you can you can fine-tune bitcoin mining like each miner is three kilowatts right you can you can selectively curtail to bring you know if they tell you to go i want 1000 megawatts to go to 654 like bitcoin mining can do that could a steel mill do this no could a refinery do this no batteries yes they they could also do something like this and then generation on the other side can also ramp up to a specific capacity as long as they have that but um that's like something very very unique with bitcoin and maybe the highest level importance of this is that if those the demand for power and the generation of power is not lined up at all times and if that frequency is an imbalance

then that's where you get blackouts or brownouts and if there was a crazy event where the potential potentially the whole grid could go down is that fair yes like voltage out of sync frequency out of sync yes it can all that's that's the the main concern and historically before bitcoin mining the primary way that load and generation demand supply were balanced was by supply changing correct the like generators coming up down is that yes is that fair yes it was by generation And then bringing that to the way that Bitcoin miners come up and down is that because each rig could be controlled on an automated basis, it can be very precise. but even though it might be good from a market standpoint if right it's 500 megawatts came offline if it shut off unpredictably the ercot not knowing it or based on some ramp down schedule

it could actually have a negative effect yes unreliability but because it is so flexible because it can be controlled as long as they are as long as they are in sync with the grid operator then it can be a real asset it requires a partnership you can't just be flipping the breaker on a thousand megawatts on a 85 mega 85 000 megawatt system like it requires you to to be a good steward um it's it's it's every large industrial load has to do something like this like there's procedures to to be there like we're playing big boy games like we are four gigawatts in an 84 gigawatt system we are making a material impact uh we are a large large consumer of electricity in texas and like like it's time to put on your big boy pants and uh

and act like it from your perspective and clearly percott's paying attention to how large flexible loads aka bitcoin miners are performing in practice from your seat how how do you think that ercot views bitcoin mining and what what in your mind is their level of understanding not to say any express knowledge but just your general perception yeah i think overall the perception is continuing to trend more positively like it's it's on us as market participants and stakeholders to to be involved and be engaged and and be good stewards We need to be showing up to these large load working group meetings up at ERCOT. We need to be having the conversations with the system operators that are in the room

operating the system and talking about what Bitcoin mining can actually do. We're in the weeds, right? We're Bitcoiners. We've gone into the Bitcoin mining industry. We know what we can do. But it's still a matter of education. like you still you still say mining bitcoin and like you'll get uh mixed responses but i do think um really it's it's an ongoing conversation uh we can't we can't rest on our laurels like

bitcoin mining in texas has succeeded because the texas market was the most primed to receive the Bitcoin mining shift post China ban but it's not guaranteed the rules can change in ERCOT, new markets can a new rule in the market can be implemented

it is on us to make sure that we are still successfully selling ourselves and performing to the standard that we are talking about I do think that

you know, overall, the value is seen. Like there's, like you can see right there on the chart that, you know, Bitcoin miners, large flexible loads are responding to price. Like we are doing what we said we were doing. Is there room for growth and is there room for improvement? And can we get those like last hundred or 200 megawatts down? Like, yes, like that should be the goal of the industry to optimize as much as we can, but time and time again, Bitcoin mining has proven to be a mutually beneficial addition to the Texas grid because we're consuming the hours that are cheap, that we're consuming the hours where we are incentivizing more generation to come online.

We're on, depending on your break-even efficiency, 75 to 95% of the time, maybe even 99, depending. But you're off on those stress events. If you're off on those stress events, you are net positive through and through to the grid. And like, it's starting to feel like we are getting some respect and we are, they do understand like what's going on. And yeah, that's okay. That's a good place to move to next. before i do i just want to reinforce something that you said i think it was i don't know what year it was maybe it was 2023 there was a because ercot is i don't know what the right way to say

this is ercot is regulated by the puc public utility commission and then the puc answers to the state legislature so ultimately state legislature regulates both the puc and ercot and there was a a bill that senator lois colcourt's put out that would have capped bitcoin mining participating to a certain percentage of one of the ancillary service programs and again the summary of ancillary services is a tool in the toolbox for ercot to help balance supply and demand to keep the grid reliable and that's a perfect example of why education is important because even if ercot is understanding it and being able to see in the market and being able to interact with the actual stakeholders people at the state house

need to understand as well because in the example you gave if it wasn't the riot being there then the cost of the system would have been greater and there might be nuance in terms of having a diverse market to ensure that the market is competitive but having that education informs policy but for somebody because i think this happened or this i know this happened When Riot went to have their second site in, I don't know if it was their second site, but their second large site in Corsicana, there were a group of concerned citizens who, if they do not understand Bitcoin, look at four gigawatts of power coming online, consuming power for a reason that they think is waste or they think is waste. they do not understand go into greater detail about how four gigawatts of power could come online and somebody might be able to conceptualize why coming offline at those peaks might save at the peak but the general dynamic of why or why not without new generation coming online how it

doesn't increase the power the cost of power overall or maybe it does you just talk about that dynamic of of maybe how power is priced how it's absorbing power that might not be being utilized in off peaks and then coming offline just that general dynamic to help articulate for somebody who wouldn't otherwise reconcile a lot of demand 24-7 or mostly 24-7 coming on with a fixed capacity of generation yeah it's and you touched on it and you mentioned it it's just a better utilization like these nat gas turbines these solar farms these wind farms they're already in the ground they already exist but the 70 or something like that of all energy is is wasted um is that 70 energy but it's not electricity but yeah and what i was going to ask is that

70 of electricity capacity yeah like ercot's capacity is much much hot like and forgive me for not knowing the number but it's over 100 gigawatts worth of capacity we're only hitting 85 gigawatts of of uh system wide peak right and for short periods of time for certain days of the year you know for you know 0.5 of the time is when that's actually happening and you know overnight maybe your your load is only down you're down to 50 or 60 gigawatts or even lower um and so basically what bitcoin does is it increases the floor it monetizes those hours that um you're you wouldn't be running that generation otherwise, making the generation more economic. But the price that the generator bids in on the curve, it stays the same.

And so as long as coming back to that price responsiveness, if price is going too high, Bitcoin goes off and the low disappears. And it's not increasing anybody's prices because actually like the studies that have been done around cost of increase of power for residential customers has been, it's largely around the distribution cost, transmission distribution cost, transmission, a smaller portion of the distribution. Distribution is getting power to residential buildings, apartment complexes. It's the wires that you see, not the massive overhead wires. It's the smaller stuff. That's the lion's share of why our electricity prices are going up in Texas specifically. Doug Lewin had a podcast talking about this. it's it's not the actual input of electricity costs there's times where there's pricing

on the grid in west texas where it's negative thirty dollars a megawatt hour but the residential consumer doesn't see that benefit because they're still getting hit with distribution charges and transmission charges and like a fixed price like the incentives need to be aligned and they're working on that for retailers um but having these large loads like the one gigawatt and course it's only increasing utilization and the economic output of a generator and if that generator is economically right like on like it's producing electrons it's paying its tax revenue somebody's creating jobs. It's creating better utilization of the assets we already have on the grid. And then also incentivizing new generation. Because ERCOT's not contracting any generators.

Generators are going at risk and responding to price signals on the grid in order to cite their generation and in order to build it. They're not guaranteed anything. There's no capacity market. high prices are the signal to generators to go out and build that load and so as system-wide load and you can see this massive uh interconnect queue in ercot that they're talking about 150 gigawatts or something like that generators are looking at this like okay this is ai this is bitcoin largely i ai but some bitcoin too we're gonna go build generation in anticipation of this and then the generation bids into the market and that's how you get your energy price.

But the beautiful thing, whether you like solar and wind or not, is that the input cost to wind generation and solar generation is $0 a megawatt hour. It doesn't cost anything for the wind to blow or the sun to shine. The marginal cost. The marginal cost, correct.

It ends up having, during the solar hours and during windy hours, very low pricing um so what does that do it shifts the peaks to when the sun's going down early in the morning during the winter uh and that's providing incentive maybe to batteries if the peaks are only two two hours three hours or if they're long sustained and we're starting to see high prices in the evening time in load zone west maybe a nat gas generation wants to go out to west texas take some very cheap uh waha gas put a peaker plant in there and they build out some more generation but the consumers are not paying for more generation to get built

generations are going at risk to build this generation based off the price and so a way to think about it was part of what you mentioned is if the total capacity of generation is 100 gigawatts in ERCOT at any point in time peak is generally 85 gigawatts that on a megawatt hour basis it's 100 gigawatts times 365 days a year and that if you i don't know what the precise number is but if you you looked at every hour versus 365 days a year 100 gigawatts capacity versus what is actually used it's probably something like 30 30 or 40 somewhere in there that if you can absorb more of that asset capacity and have greater utilization the transmission lines are there that it increases the profitability which allows the economics to improve and also flattens the

curve and that's a net benefit maybe shift to talk about because you brought up two things you brought up ai and batteries let's let's talk about both of those but first bitcoin demand for power and its characteristics relative to something like an ai the resources demand for the power how are those similar and how do those differ and what would be the considerations for a grid system or grid operator like ercot looking at both of those yeah and they're and they're definitely different loads even though they may see some seem similar but what i will say is that bitcoin mining paved the way for these ai data centers to come to texas 700 megawatts at you know rockdale in one gigawatt at Corsicana like that is an unheard of level of interconnect data centers

prior to this AI revolution were maybe high double digits low 100s of megawatts so like what so I'm going to pause pause that thought because there was something else that I wanted to talk about um that feeds into this which is we talked about ercot being a deregulated energy market and that what that means is that generation is deregulated and then the retail market people actually selling power to commercial loads homes that that piece is deregulated the transmission and distribution is regulated and there's a process to being able to interconnect correct to the grid and that that's a long process so talk maybe distinguish between the regulated pieces and the deregulated pieces and then how that factors into this discussion

of how long of a lead time it might take to get a 500 megawatt site online and connected to the or a gigawatt site? I mean, we'll tie it back to the reliability piece, right? Everything is under the guise of reliability. You see this massive load interconnection queue, hundreds plus gigawatts. Encore, AAP, the TDSPs, the transmission distribution service providers, the wires companies, they have to take these interconnect requests and be like, are they real? We've never seen something this big like we've seen a couple bitcoin mines like this this is unheard of demand uh and then they have to work with ercot to make sure that the system operator uh like nothing breaks in their model and so it's a it's an aggregation of you've got your

load you've got your tdsp and you have ercot all working together to try to fit 150 gigawatts plus into an 85 gigawatt peaking system and so it's there's a lot of um basically it's unprecedented like there's they haven't seen something like this before and this amount of growth is utilities grew at maybe single digit percentages post-covid orcott was growing maybe six seven eight percent which is a very very very high rate compared to everywhere else uh we're talking like estimations of 15 of able to actually get done but uh what they're requesting is is 150 of what the ercot total system-wide peak is right now uh and so that's wild it's it's absolutely insane and it in their right to take a step back and be

like is this real like do we actually have to serve this serve this load um and so these ai data centers there's different types of data centers like you've got the you know the models the training model uh training the models that can be um you don't need as good of latency you don't need to be in the the city centers those might be the ones competing for competing with bitcoin miners like going out to deep west texas going to stranded assets then you have inference inference compute what's actually running your chat gbt answer inquiry uh humans are okay they're all right with waiting a little bit we understand that like okay it's got to think for a second um that inference compute that's closer to the city centers uh and then you've got the the edge

whatever but right now what we're seeing in texas is dallas is a hot spot south dallas is a hot spot for ai compute then you've got north of austin you've got samsung you've got the gigafactory data centers are coming there but you do have them coming all the way out to west texas and And that maybe is where the intersection of Bitcoin mining and AI compute will be. Galaxy just contracted with CoreWeave for their entire capacity. And so what we're seeing now is... Galaxy Digital? Yeah.

Okay. Their mining. Their mining business is... Their Helios, their flagship site, has completely decommissioned the mining infrastructure. is working towards converting to strictly ai hpc or core weave and but say just for a single site say if a setting aside this crazy amount of forecasted growth based on all of the requests that have been put in you want to get a 500 megawatt site online in ercot what does that process look like and how long does it take good luck is uh is what i would

say right now everything has more or less uh ground to a halt uh we came in at the right time and we were early and were able to secure these interconnect requests they will they still have like an obligation to serve and the tdsps have obligation to serve what is tdsp transmission and distribution service provider however the time to interconnect now for a large load we're talking years and years and years down the road like there is no easy access to power anymore that has been more or less taken up within the last year or two with with all this increased load interconnections and so the reason why the ai data a bitcoin mining data center might be so valuable to an ai operator is the ability to access large amounts of power

without having to get a new interconnect approved through ERCOT? Yeah, I think we're going to see this. And I mean, we're already seeing this. Building out generation and power infrastructure is a matter of national security at this point, right? Like we're betting on AI. It's an arms race. And it comes down to who has the most energy and power and electrons.

and so we it's it's imperative that we do we do so uh right now they're trying to get all capacity that's left on the market when that capacity dries up and we're looking at three four year interconnect times and they have nothing in their pipeline this is where i would see like the mag seven you know picking off the large interconnects so you know like iron's doing this right now like they've become a preferred partner of nvidia they were they started bitcoin mining in childress west texas close to the panhandle lots of wind decent amount of solar uh straight near lubbock uh yeah it's on the way okay it's on the way or on the way to amarillo okay 287 or 187 anyways yeah it's it's on the way up to like denver so it's on that fiber corridor

actually of dallas to denver and so they're like a great prime example they're monetizing the electrons with bitcoin mining to start and then marketing this to the ai and hbc compute companies like hey we have this power if you want it come and get it like we'll sell you the rack space um maybe there there's going to be like total acquisitions right like riots i know riots right now marketing the rest of their Corsicana site. They got 400 megawatts worth of Bitcoin mining currently energized, 600 megawatts of latent capacity. South Dallas is completely locked up. Corsicana is not that much farther south than Dallas. It's only an hour drive away. Very easily can see the sale of 600 megawatts, whether it's a total acquisition of Riot or it's

it's them selling that 600 megawatts or them hosting with that rack space. So maybe talk about what is the difference in profile in terms of what an AI data center is willing to pay for power versus what a Bitcoin miner might be willing to pay. We're talking orders of magnitude different capex spent. one gpu's something like eighty thousand dollars it's it's producing flops or something like that well one gpu is how much i've heard numbers of eighty thousand dollars i'm not in the weeds of

this thing but like they're they're very expensive so they are incentivized to be running their compute as much as possible um i think their generalized break-even number is a thousand plus a megawatt hour go ahead you're gonna say something yeah so a bitcoin miner an asic is between four and five thousand pricing wise yeah yeah you can even get some cheap used ones but your price for the asic probably 500 bucks to 5 000 and then your price is 70 dollars per megawatt hour to 150 dollars a megawatt hour currently okay i'm trying to just think about some of the unit economics so that's don't use my 80k i'm not gonna use your 80k but like let's say 50k yeah and maybe be conservative how much power does a on a relative basis does a bitcoin asic

draw versus a ai gpu asics you know air cooled asics we're looking at low 3ks hydrodes all up to 10k w okay and then immersion somewhere in between like five or six thousand i know that right now the gpus so they're making it up as it goes by the way like what bitcoin mining went through and like s9s to s17s to s19s like this really quick iteration and burn and churn is happening right now with nvidia like the racks for cloud compute like your your compute that ran your netflix that runs your google query like your traditional internet infrastructure was like 10 or 20 kilowatts per rack and a rack is like a 48 unit um it's a it's a little taller than a person it's like seven feet tall maybe uh 10 to 20 kw they are now talking about trying to

work towards one megawatt a rack like the density is getting absolutely insane they used to use like rear door heat exchangers now they're going strictly direct chip hydro and but contextualize that relative to bitcoin yeah to bitcoin the same the same rack and we were we were breaking barriers like 200 kw a rack is what you can put in um with bitcoin mining asics with like the what's minor hydro or the aridine hydro or the canon or bit deer those two u hydro units that you see um they consume 10 kw uh and you can put about 200 kw inside of a rack and so i don't actually i don't think h100s are and that's like a common gpu that nvidia makes i don't think h100s are to that 200 kw yet i don't know if they've commercialized 200 kw but they've they're talking

about in the future of having 400 600 kw racks and like they're going for as dense as possible as my understand my and maybe this is a shift that's happening because of ai was that the shift from gpus to bitcoin a6 the power density of bitcoin a6 was far greater than the power density of a legacy gpu but maybe the gap is shrinking because of the nvidia chips and ai is that we were 100 more dense uh before like it like i was like i was saying like 20 kw is what your your normal racks uh heat capacity was or power capacity 200 kw is what bitcoin was this was you know like rewind three years 20 kw data center 200 kw bitcoin mining they're catching up i don't think they're at 200 kw rack yet but they do plan on passing us in like rack density and

my understanding is that the build-out of an ai data center is far more expensive something like on the order of magnitude of 10x the cost that's less consequential than they're willing to pay way more for power and that is because whatever their end market is their their revenue source is greater than bitcoins on a hour per unit economics is that fair yes i mean their capex is is higher but that's their cost yeah but they're but but they're their willingness to pay and you said potentially up to what per megawatt hour figures i'm hearing somewhere in like the mid one thousand dollars a megawatt hour versus bitcoin mining effectively being breakeven

somewhere between 70 a megawatt hour and 150 yeah what we were talking at the beginning of this episode about real world examples where in total in terms of all the bitcoin mining that is in urquhart going from 1.5 gigawatts to 1.9 to 2.2 to somewhere around four gigawatts today and that flexibility of the load being a value to the system is ai flexible why or why not and talk about that in relation to the nature of the differences in the load it's a good question and i think it's still yet to be determined like google has put out some white papers talking about load flexibility they all know that flexibility is important they know you can't just be running you know 99.99 like they

call it the five nines so like 99.59 uptime is what the industry standard for a data center uptime was um and if they want to if they want to maintain that they know that they can't rely on the grid to do so where we're at because there's an insatiable demand for power uh there's the opportunity you know for ercot to engage with these conversation engage these hyperscalers in this conversation like we need some flexibility like how can you build systems to do so and because the gpus are so expensive and because the capex spend of these data centers is so expensive they're able to add in ups systems like what's a ups system um uninterruptible power supply they can even put in grid scale batteries you can put in e-stat comms which helps with like

voltage issues uh because because their capex spend is so high they can add reliability uh you're effectively saying backup generation well and then i was getting there and then they also have diesel backup generation too so like they have all of these different tools um that could be used to help reliability you know you could switch over to onto your battery in like a grid scarcity event right they're consuming just like us for you know most of the time price goes high ea event something like that bitcoin miners are just turning off fine whatever we don't we just need to sell our compute into the bitcoin market data centers could switch over to their ups slowly ramp down what the grid sees they could then kick on their backup generation

and then get them to like a checkpoint or to where they need to be on say their training model or Or reduce load to a certain extent. There are tools and ways to make all of this AI growth in Texas not an issue on a reliability standard. And that's what we're trying to do at Shoya. Yeah, where I'm getting to is that a ai data center is right and everyone throws around the term ai and you know it'd be chat gbt someone you know mid-journey you know the end market is people typing in requests to

grok at gbt mid-journey and operations are happening at a data center and then push back out that that might not be as complex or sensitive as an operation as a um as a foundry working on asics or a smelter or a hospital but it is still a source of demand that is more complex and if they were just to go down then the then the thing that's actually paying a thousand gigawatt or sorry thousand dollars a megawatt hour for power that it would be interrupting and so it's not so much a complex energy problem as it is a service delivery problem whereas in bitcoin miners they're when when they shut down the bitcoin network works perfectly well right because everyone is providing power to one

aggregated source of demand versus on the ai side it is customers paying for a service and if you typed into the grok and you were paying for the service and you didn't get response back because the service was down because texas was having a scarcity event then you're not going to be willing to pay thousand dollars a megawatt hour plus as the end customer so it might be possible in the future but it doesn't seem like the ai data centers are getting near the the concern trolling that bitcoin miners do or were and it might actually cause a problem if all of this because i can understand economically why if there's four gigawatts power in texas that's being consumed by large flexible loads and maybe not all four gigawatts large flexible loads that

are above 75 megawatts but say 3.5 gigawatts are if bitcoin mine or sorry if ai data centers are willing to pay 10x for the power then the economically rational response to that is to sell your site or sell lease your site however you do it transfer it to an ai data center But then the benefit of having 3.5 gigawatts to 4 gigawatts of large flexible load that can be hyper responsive to scarcity events in a very direct way goes away. So is that part of the discussion that people are having out there in the market? Or is it largely not because the power brokers that be are Amazon, Microsoft, Google, and twitter grok what's the perception of that you know i think we don't know we don't know because

abilene like the stargate campus the 1.2 gigawatts like it's it's still being built like there's there is data center load in texas but that's traditional data center load this new um ai compute it's it's it's not here in any sizable way uh but you're you're completely right like bitcoin mining completely pure economic signal like we will respond to the price signal ai's price signal is a lot higher right and they have a different more convoluted equation to like their their payback and like service to their customers and like downtime and all this type of stuff i think the i think the key is is that low growth is good for texas because low growth means more investment dollars like it's trillions and trillions of dollars are going to flow into texas

if texas gets this right the key is flexibility like erica has a position of power at this point like they they can they have the best most competitive market and grid system permissionless Jen can just connect and then manage. We want the load to be here. We want Bitcoin mining to be here because it's a different load profile and it's going to be at a different place. Bitcoin mining, it can be two megawatts. It can be three megawatts. You don't need scale to be a profitable Bitcoin mining. These AI data centers, they're looking for 500, 600, 700 megawatts plus. They have become a whole nother beast in themselves. Bitcoin mining actually doesn't need to be that big and honestly well maybe say explain that why why does the ai data center need

to be that big it has something to do with like just having shorter networking runs between the whole entire cluster of gpus i'm not an expert here like yeah yeah just like close proximity of all the gpus in one location helps them on their training and so trainings so what we were what you were talking about are like querying grok that's inference um so that's one type of compute gpus can give the other compute is like training the model that brock is querying and so when you're doing these training runs you want a lot of gpu and um a lot of gpu compute and you and you really want it in one location and that's why people are looking at the you know the irons the galaxies the riot because there's a lot of latent megawatts in one location there

was no other load on the grid that ever requested 600 800 megawatts a thousand megawatts like bitcoin mining came the way yeah how large was a traditional data set like a large traditional data center are 20 megawatts right so there are at least 10 that i know of 300 megawatt sites in texas correct and so the the bitcoin miners effectively built sites that could offload from the grid large amounts of power and very dense ways we paved the way we gave ercot a stress test and going through the procedure of interconnecting one gigawatt worth of electrical load it's compute like we're we're doing a different type of compute it's a shot 256 hash instead of a flop or whatever ai compute is but it's it's an

electrical load on the system and what we did was pivotal to the future success of our comp with ai compute yeah and i mean that that makes sense to me in terms of figuring out how large loads of that size and scale which hadn't existed before would interact with a grid under a certain set of conditions with a lot of flexibility and flexibility that was seen in practice now re-entering a world where they're that it might be in theory but not proven out yet and that the concerns over the nature of the large loads that bitcoin received were largely misplaced because of their flexibility but it might be the case that with the lack of flexibility or at least not having a a model proven out that allows for that flexibility so i couldn't imagine a diesel

you know if there's a 500 megawatt site having a diesel backup generator that can materially replace a large amount of what might be going on at an ai data center site at any point in time and it's not to say that hey there should be an incentive to service all large loads and to incentivize more generation to come online but you might be looking at a very different load profile because of the economic incentive model for ai companies that differ significantly from bitcoin companies how now pivoting now to so we talked about ai you mentioned also batteries if bitcoin mining is a form of demand of power load ai form of load batteries can be both demand and it's not generation it's not actually generating power but it can

stores power and can supply power back to the grid talk about bitcoin mining and how it can be a service to the grid relative to how batteries have a place where they complement each other what one can do that the other cannot vice versa and where they potentially compete yeah so you see now that pretty much any solar farm that is being built is being co-located with batteries uh batteries help improve the economics of solar farms uh bitcoin mining would do so too where the where i see the main difference of bitcoin mining before you go into that yeah we had one of your choya interns yes in here a month or two ago i believe a texas a&m student yeah robert yeah he was explaining something about why there's a benefit to having a battery

co-located with solar not just to have over capacity to be able to serve a consistent mount but like actually from a technical perspective that there's something about frequency that was a little bit over my head that allows for frequency management by first putting solar to a battery and then connecting the battery to a grid is that my wrong there i could have totally misinterpreted you are 100 right like the batteries have such fine nuance to the amount of power that they they can inject that's why they're taking the lion's share of the ancillary market because they respond so well so yes it is true like like it will smooth out any fluctuations and that's why fluctuations in frequency like output okay generation output okay and so that

that's why data centers are also implementing innovative battery solutions because sorry to go back to ai real quick but like the inference and the compute it could go up and down it's bitcoin mining when we're on we're kind of just flat and going for it uh these training models they can go up they can go down like it could be a mess like it would absolutely not be a good thing to to sub subject the grid to like instant on instant off at large loads of 1.2 gigawatts plus plus plus um and so they're using batteries to do that like basically spoof the grid and say like hey we're actually just flat and so i'm assuming the same thing can be done for solar i don't know the technicalities behind it but yes i believe that's what it was yeah yeah so like the grid

wants you know nice and nice and stable bitcoin mining nice and stable battery output nice and stable uh ai inference and compute not so stable but back to back to batteries the thing about batteries is that they only have a a they're constrained by like how many hours of charge that they can actually charge and so a battery might only be able to consume power for two hours worth of the day, or I think they might be getting to four, you can only discharge for four. So it's got eight hours of total in and out capacity. Bitcoin mining is 24-7, right? We can consume the entire day. If prices, say it's on a shoulder month and it's super windy, super sunny, and prices are $0 the entire day, the battery will have been charged and stay at the

same state of charge the entire time they'll probably in this case bid into the ancillary market um and like provide those like frequency support services whereas bitcoin if it's zero dollars the entire day we're going to be blasting like full-on monetizing those electrons and so i think the they're both flexible i would say batteries are better at like very very nuanced it's a it's electronics right like you can you can set the voltage or set the output to like a very nuanced degree bitcoin mining also flexible maybe not as nuanced but the benefit that bitcoin brings is that you can much you can oversize it considerably and you can run it for a larger amount of time and explain i didn't fully grok what you were saying about the um the charging

the amount of time like what what is a large battery how large is a large battery first oh um battery installations nowadays are i think a couple hundred megawatts okay there's 15 gigawatts so 15 000 megawatts worth of batteries in ercot right now wait repeat that amount 15 000 megawatts or 15 gigawatts of batteries in ercot would that how much would that have been five years ago order of magnitude zero okay pretty much effectively zero uh they've they've come on super strong in the last couple years and so take a hundred megawatt battery yeah is that actually like one just massive battery or is it a site that has it's it's a series of batteries and so like a hundred megawatt battery has a hundred megawatt

hours so it's megawatts like being able to deliver to the grid and then there's like total capacity so like maybe it can only inject 100 megawatts at a time but it can hold 200 megawatts so it's 100 megawatt two-hour battery okay i think i follow that so if it's got 200 megawatts of capacity it can take a hundred megawatt charge at any point in time but then there's a certain number of hours that a 200 megawatt battery could supply say 20 megawatts of power yeah i think it's based off of and forgive me for not knowing this but i think it's based off of the inverter size like i don't expect you to be an expert on everything i'm looking for you know general knowledge here yeah i i believe the way it works is that it's it's based off of like the inverter

like how much you can convert from dc to ac and and send through it so say you have a 400 megawatt pack and you can send 200 megawatt hours through it at a time that's a 200 megawatt two-hour battery got it and then once it was depleted it need to be recharged correct and it can only maximally charge 200 megawatts at a time they could probably go less than that if they wanted to spread it out and provide more even uh charge but it can only take 400 megawatts total 200 megawatts an hour whereas if you have a you know a 200 megawatt bitcoin mine you're consuming 200 megawatts or 24 hours significantly more it's your the utilization of the entire grid is much better on a bitcoin mine than just exclusively a battery and then if you have batteries distributed

it's basically got stored power that can that can provide incremental supply to the grid at a point in time so talk about that so you talked about one circumstance where battery could in a much more fine-tuned balance not necessarily the grid but some other demand for power talk about the scenarios where bitcoin mining could help balance the market for power more effectively in a broad like at scale versus batteries like what i think like conceptual scenarios you know i think the unique thing about both of them is that they're location agnostic like you you have well as a as a battery you are injecting as a generator and like injecting to a they consider batteries generators yes i think they're considered both they get the treatment

of both and so and like we're getting back into the weeds of our cut here but like as a battery you're injecting at the nodal price as a load bitcoin miner you're in you're drawing based off of a zonal price and so actually the thing that um works to the battery's favor here is that um the node's a better signal right if you if you aggregate all the load the nodes together you get the zone the zone could have how many zones are there in ercot there's west north south and houston okay four and those are the deregulated zones like within those zones like you have the co-ops and the municipalities that aren't deregulated um i said co-ops but anyways you have those you have those four zones and so i'll talk about loads on west is where we're located

and i know i know best and and maybe there's there's many nodes in a zone yes just for some context even though different zones probably a different number of nodes how many nodes per zone i believe each generator will create a node uh so load zone west for example i'm pretty sure there's got to be 50 to 100 nodes and the the nodes themselves will have a will have a price point and then the aggregation of those nodes will create your zonal price that your load responds to okay because yeah before you had made some comparison between nodal pricing and zone pricing now reconnect that to the idea of batteries how they might benefit from one or the other sure like the for example deep in deep deep west texas talking like pecos for stockton area

um a generator could trip or it could it just couldn't it might not be windy and so that deep west node will get blown out it'll go to five thousand five hundred bucks a megawatt hour and then based off of that high price the zonal price for the load increases but it might not actually reflect the electric like the electric grid conditions on the eastern part of the zone in Abilene, right? You're 400 miles away, multiple, multiple buses away. They're not very electrically connected. And so where batteries are nice in this situation is that they operate on the node. And so by operating on the node, you get a clearer price signal. But to be fair, or to circle around, Bitcoin mining, loads can't operate on nodes to get

better price signals it just requires uh qualification to become a controllable load resource this controllable load resource allows you to operate based off of nodal conditions once you qualify uh with ercot's conditions um and then at that point like bitcoin mining truly is like an apex predator for responding to grid conditions because you have your node that you're your most electrically close node if you're responding to the prices and conditions at that node that is the the clearest signal for scarcity or abundance that there is and so if prices are cheap there's abundance of electricity and you're consuming like and you're consuming price gets blown out just at your node and you can turn off that helps like spread spread it

back out and like reduce that nodes um blowout and then that improves the prices for every single person in that zone because not everybody can be a clr and so if i'm thinking about this correctly if a generator trips then either a bitcoin mine could come down if it caused prices to spike or a battery could replace that power or both or both or combination it's not mutually exclusive like they can both respond to the the proper price signals or as demand is increasing a battery could provide more power where a bit you know often oftentimes there are people that will say bitcoin is a battery my view it's a bad analogy because it can't provide incremental power to the market correct it can turn down and allow a generator that was providing it

it power to have that power go somewhere else but can't replace the power right does that if you need more power or need more generation a a battery could provide that more efficiently where a bitcoin miner could not yeah just for two hours right but the bitcoin miner could stay off as long as the economic signal signals that the generation asset has like state trip like some type of issue and so it might be the case where and i'm not saying in a specific circumstance but a a battery might provide the first relief to price signals but then if it's needed for longer the bitcoin miner would be more responsive i think it would be you know depending on the price of of power right i think they would both respond to the price um but

bitcoin like the battery is capped to its level of response although it is you know it is injecting it is providing that power support bitcoin mining can stay off for longer like another another really good example um of this was this was this summer i can't remember the month but prices the batteries discharged for the solar ramp in the evening in the afternoon was the batteries discharged injected into the grid like they sent power into the grid as the sun was setting and solar was coming off of its its ramp and so for those two hours three hours batteries were injecting prices were maybe 120 150 bucks a megawatt hour 300 whatever it was um overnight it wasn't windy and so prices stayed in that maybe 80 to 100 a megawatt hour range

which is significantly elevated versus where which is elevated comparatively yeah and then in the morning there was another peak like there was a there was a morning peak of demand the batteries had not charged because of the that 80 to 100 price range and as it peaked to maybe 200 a megawatt hour the batteries were sitting there like twiddling their thumbs like oh we're out of capacity there's no discharge whereas bitcoin mining right you're off at that solar shoulder and then as long as your break even is like you've got some newer efficiency machines at 120 you're soaking up all that electricity at night and then when that peak goes to 200 bucks big one responded and so we have a we have that ability to always respond

batteries have to worry about their state of charge and it's it's more of a guessing game it's less guaranteed so they they they can both be compliments and they can both be responding at the same time and be you know or you could think about that as being competitive to how they're providing or how they're responding to price signals you know ercot needs everything we need gas we need solar we need batteries we need wind like the the more it grows the more load grows the better texas does um you know batteries provide things like like voltage uh ride through support that electrical loads can't do like it's all going to work together and because we're in an island system a variety is key like it's and you mentioned

batteries increasingly being co-located with solar are are most batteries co-located with some form of generation or do they do they typically i mean you want to put it next to intermittent generation right because if your gen stack is built for if you have a one gigawatt interconnect and you size your nat gas generation to one gigawatt like you couldn't inject any more than that one gigawatt so it wouldn't really make sense to charge your battery if you're just using a gas peaker plant where it does make sense is that you're generating your one gigawatt solar plant you put one gigawatts of batteries you charge during your um you know your did i say solar or wind uh solar solar you charge during your your sunny sunny time and then you have

one gigawatt worth of capacity to sell on those times where you literally can't be injecting into the grid when it's in the evening time um and then when you if you talk about right here but just if we look at the landscape from yeah somewhere between 2017 and 2019 gideon and went out and from my knowledge built the first greenfield substation that was 50 to 100 megawatts ultimately to be 100 megawatts in terms of the phase but that was the first greenfield substation for bitcoin mining virtually there was there was bitcoin mining on the ericot grid in 2020 but in terms of getting to four gigawatts today five six years ago it was very de minimis similar with batteries you said it was something like

15 gigawatts now today of battery power so a lot has changed over the last five years if we look five years into the future specifically on the bitcoin mining side where do you see the scale going and where's choya most focused today in terms of participating in how you guys see the market changing i'll hit on bitcoin mining like i bitcoin mining is a unique load profile to ai compute that that we are competing for power against. I do think that you're going to have less of these mega miners, hundreds of megawatts, and you're going to have more distributed 50, maybe even

sub 75 to avoid the ERCOT large load classification. And then you're just opportunistically citing these around areas that have an excess of power generation. You're going to have Bitcoin mining behind the meter at wind farms that are just putting a floor PPA on that wind farm, helping to monetize the excess energy there, and then just dealing with a 60% or 70% uptime. I think the days of the one gigawatt Bitcoin mining ventures, or at least in Texas, are probably over. We just can't command that premium.

like you could take a one gigawatt interconnect and sell it to a hyperscaler of course this is all like given the data that i'm i'm seeing now with ai like is a bubble like we're not going to get into that like like will things change who knows but if it's on the current trajectory i think that bitcoin is going to just continue to be like the pioneering species like we're going to go collate locate next to the intermittent generation we're going to go co-locate um you know wherever these large data centers don't want to go um and then how joy wants to position itself you know like like you were saying gideon gideon saw this flexible load like monetization back in 2017 2018 and built that that spec built huddle one substation in uh in piyo and then just

everything that happened the last eight years was a confirmation of like what what he was talking about. You have the mecca of energy in West Texas. You've got oil and gas, the most prolific field in the world. You've got wind and you've got solar. You probably have geothermal too, but it hasn't really been commercialized, but you have so much energy right there. And if you can respond to the prices, which was the thesis with Bitcoin mining, you can capitalize on it. Load Zone West, where Gideon first um built that substation and sold that project was the start of the west load zone tripling in size over the last eight years like I'll say right here like he started that yeah um of course there's some oil and gas load in there too but we're also an oil and gas company so we'll

uh we'll we'll put our hat into that too um where Choya sees opportunity like what I do at Choya's is um is run our innovation lab where we take low serial number units and uh and test it out we'll take on the we'll take on the technology risk and so with all these ai data centers coming onto the grid like are we going to go like is off-grid the solution like and you know is it the traditional off-grid is it it's like flare gas mining is it putting nat gas you know turbines on a pipeline and creating your own energy? Or is it some combination of solar, batteries, and gas? Because solar and batteries, the cost curves are just continuing to go down. They're being built as consumer electronics. We all know technology stacks and electronics, price trends down over

time. And they're just going to become more and more competitive. So we can imagine a world where you can have massive off-grid solar battery farms powering Bitcoin mining. Will it be Bitcoin mining at first? No, of course not. It's going to be AI compute first because they're generating a higher dollar per megawatt hour basis so the unit economics work better for them.

Where Choi is participating right now is like we've we've got expertise in the oil and gas side the land side and the um electrical side and are trying to speed things up in our guy like it's i talked about it earlier like we see it as a matter of national security in order to have as much ai compute in the united states as possible And the more that comes to Texas, the more benefits Texas stakeholders. So our focus is accelerate that in any way possible. Gideon was super involved at the legislative last year, lobbying for flexible load and using Bitcoin as an example to basically troll these AI companies like, hey, we can do this.

Y'all should figure it out too, because we've got four gigawatts and we're turning off. and like sending that power back to families and homes y'all can't tell us that you're too important to not do so and so long way to say like we're we're involved in all all things energy power uh and just excited for the the future of texas and and how much it's going to grow and how much it's going to benefit all of us well when you mentioned that you guys view more ai demand as a matter of national security i was going to say are you talking about texas or are you talking about the united states and then um is more bitcoin mining on that same par why and and this is the last question to wrap up and

then also want you to share where people can find you if they're interested in what you're doing in the innovation lab or outside that um where they can find brad cuddy you know of course it's good to have ai compute in the republic of texas uh but overarchingly in the united states having this compute and owning this compute is important as like we are obviously competing against china state-owned utilities state-owned generation they can just build transmission they can just build generation as much as they want they can put old chips on and run these models like it is their model versus us like will america's will to innovate the capitalism structure that incentivizes growth and innovation and you know thinking outside the box and allowing entrepreneurship

will it win i don't know i hope so i believe so but how do we ensure that they're like we do what we can to make it win access to electrons which is the input to all this compute but that is like our north star at cholla and then for bitcoin mining of course i want as much bitcoin produced in the united states as possible uh because i want americans to prosper from energy back freedom money i can i can see a see a world it's like as ai continues to um gobble up jobs maybe their ai agents start transacting on it with each other like bitcoin bitcoin will be a part of this and like we we all know it um how do we make sure it's a part of it so one on the bitcoin mining side is like what what i'm trying to do uh we are a complement to the grid we're important for

like we're here to stay um we're not competing against ai it's it's it's a different class at this point um but of course decentralization like not all not all bitcoin money needs to go to texas like it it's a pioneering species it should go where it's needed bhutan great example my favorite one. The government of Bhutan having 12,000 Bitcoin on their balance sheet because they said yes to Bitdeer mining on their stranded hydro is the coolest thing ever. Long live Burkhart, long live Texas. And then you can find me at, I think it's underscore Brad Cuddy underscore on Twitter, LinkedIn too. I got a pirate flag and laser eyes, so pretty easy to find. But really appreciate it, Parker. Yeah. Appreciate you coming on, running the

innovation lab at choi inc in many ways urquhart at a great scale is an innovation lab for the rest of the nation or the world to pay attention to so appreciate all that you're doing individually choi is doing and thank you for coming on the show glad to have you in austin great to be here all right thanks parker yep
