This sounds like a good reason to have a lot of batteries.

A lot would probably be an understatement. Aren't most batteries in data centers designed to just hold load for seconds or a few minutes at a time while generators start up?

zephen• 1 month ago

Yeah, different batteries, different purposes.

Keeping the data center up is completely different from keeping the grid up.

Not only are the batteries too small; they're also on the wrong side of the disconnect.

jeffbee8• 1 month ago

If the problem is an instant disconnect of a large load, switching that large load into charging batteries at that instant, for a minute or so, feels like a solution.

I'd rather see legislation banning crypto mining and AI data centers from the public grid entirely. No sense in forcing the broader public to subsidize them.

MBCook2• 1 month ago

The problem with that is one of the best things we have to control pollution at power plants is the rules that go into place when connecting to the US grid (I know TX is different).

I really don’t want to incentivize private power plants that aren’t on grid. Or just running tons of industrial sized generators instead.

If we’re going to allow enough of this stuff to be built that it can destabilize things why not require they behave and don’t stop off like that? Some sort of organized draw down?

And if they don’t? Mandatory cutoff for X amount of time. Weeks/months.

rickydroll2• 1 month ago

If they weren't on the public grid, they would just slap in a bunch of gas turbines and run one of the noisier, more polluting sources of electricity. I think it would be better if we required them to replace the power they used, but do so on the grid so that it benefits everyone.

I'd rather see legislation banning everyone from the grid. Why have a common resource if its no longer common. Just get rid of it. Ban everyone from using the roads, who knows, they might be transporting evil computer hardware to an evil data centre using a road. Farms obviously have to go, they supply food to people who write code that gets run in datacentres. In fact, just ban all trade and commerce to be on the safe side*

*The US should implement this policy for real for my personal amusement.

I’m curious how this works for other large consumers. Do they have some kind of artificial load that lets them gradually reduce consumption instead of doing it all at once?

threwrfaway8• 1 month ago

If you're large enough your connection to the grid is a negotiation with an engineering team.

The utility will force you to put equipment to correct for power factor (massive capacitor bank), resistive load, etc.

The utility also charges commercial users for apparent power (includes reactive power, or that sloshes around setting up a steady state), as opposed to just real power charged to residential users.

EDIT: in case your wondering, yes resistor loads is just glorified bunch of short circuits and a fan.

threwrfaway8• 1 month ago

How about an across the board $1/W hook up fee for new customers? Thats about the price of installed capacity per watt.

New house with 200 A panel an assumed 30% utilization rate? $3600.

New data center with 80% utilization rates at 100MW? $80 million dollars.

New 10 GW data center? That'll be $8 billion.

It's outrageous that I'm paying an extra fee to export energy to a neighboring state to power a datacenter.

mindslight2• 1 month ago

Your math on the house seems off by a factor of 4? But 30% utilization seems high, as that would be a $2k/mo electric bill at 20 cents/kWh.

Reframing what you're saying, that would be a connection fee that worked out to just under 12 cents per kWh used for the first year, which seems both somewhat reasonable but also probably not going to move the needle much on the large deployments?

threwrfaway8• 1 month ago

I guessed what the utilization factor for a house was, purposely going for a very high number to show that it wouldn't add too much to the house.

Note, In proposing a one time fee, on the capacity to generate power, not the energy.

HWR_14• 1 month ago

Texas has an independent energy grid, so are not exporting energy to them.

In fact, I don't live near Texas. My state is having me finance a power line that will increase demand for our electricity.

askvictor• 1 month ago

Yes, although, with enough datacentres, it starts to get linked to other grids via data i.e. it starts 'exporting' its energy via compute

phil212• 1 month ago

It's outrageous that I'm paying an extra fee to export energy to a neighboring state to power a datacenter.

I don’t find anything outrageous whatsoever about building out transmission to strengthen regional interconnections. Lord knows we are decades behind the curve on this. If AI datacenters are what finally lets us maybe start to get a tiny bit ahead of the game I’m all for it. When the bubble pops there will finally be a bit of pressure off, and perhaps we can get back to a tiny bit of overbuilt capacity to cover for exceptional events again. And more reasonable projects maybe won’t be sitting in a decade long interconnection queue.

At some point we get to all collectively pay for our parents lack of investment in energy infrastructure. We have been living off our (great?) grandparents investments into the future and wide scale deindustrialization of the economy since I’ve been alive. At some point you run out of inertia.

Could always move to Texas if you hate the idea of your state ever possibly spending a dollar that benefits someone across the border. They islanded their grid pretty much precisely due to this attitude.

Watching the PJM and MISO interconnections over the past decade or so has been illuminating. It’s been a very slow moving disaster in the making that nearly no one is paying attention to.

As for your proposed solution I doubt anyone - including the datacenter operators - would argue since that is largely what tends to happen as it is. Just change utilization factor to capacity factor and sounds good to me!

bob10292• 1 month ago

MISO

As a retail electricity customer, I vastly prefer whatever is going on in their operational context.

I live 10 miles from the "border" between ERCOT and MISO and I've got a lot of experience with both, particularly in disaster scenarios. ERCOT is a total shitshow when it comes to the edges. The fuel mix in MISO is pretty terrible for the environment, but it is also unbelievably reliable. The Mississippi River is not to be underestimated in its logistical impacts. The price of natural gas drives the daily fuel mix proportions, but it doesn't affect the available base capacity and its financial status (fully amortized for over a generation). If natural gas gets expensive in ercot and the wind isn't blowing, there isn't anything else to give. MISO has 2-3x the coal and nuclear capacity that ERCOT does.

Aurornis• 1 month ago

All projects have an interconnection fee.

Large projects will have a large load interconnection tariff that’s supposed to shoulder the costs of upgrading the infrastructure to support these new projects.

Data center discussions are weird right now because people assume these things don’t exist and propose them as solutions. They already exist.

The problem in the article is something different: The sites they’re talking about are designed to disconnect from the grid and use backup power when the voltage drops, which can be a problem because now there’s too much energy being supplied to the grid and not enough load to absorb it.

AdamJacobMuller• 1 month ago

Isn't that fundamentally a coordination problem?

When voltage is dropping (or phase is falling out of alignment) don't you want to shed load to stabilize? The issue seems to be more that too much load could shed too quickly causing wild oscillations in grid conditions from an undervolt to an overvolt. Seems like the correct, and not terribly complicated, solution to this is to have a process whereby the grid operator can request large customers to shed load and move to backup power temporarily.

That seems like such a reasonable suggestion that I would be shocked if such a thing does not already exist and is simply just not reactive enough and too manual.

No, because that doesn't go far enough and still shifts some costs onto everyone else.

Right now, they're using privatized-deregulated communism to privatize the profits and socialize the costs. Everyone else shouldn't pay for these goddamn DCs.

ilaksh• 1 month ago

This almost seems like a straw man to me. Isn't the much larger problem the actual increased energy usage and making sure that all of this massive extra cost doesn't just get dumped on consumers?

I am a huge proponent of AI actually, but very suspicious that "financiers" are suddenly creating what amounts to an energy tax by finding legal ways to sneak extra fees or rates into our electricity bills to cover build out and commercial usage costs.

But as far as smoothing out demand, my (admittedly a layperson) theory is that we need to force them to adapt more solar and wind and at the same time more facilities for handling the variable production from that. Such as more large batteries and a shift to large scale long term storage of renewable fuel like hydrogen or other fuels produced directly from renewable sources.

If you have a large production and storage of renewable fuel, then maybe you can build that in such a way that it can handle significant input variations that could include excess grid power.

jeffbee8• 1 month ago

Texas is the standing proof that "making sure that all of this massive extra cost doesn't just get dumped on consumers" is not a problem. Texas has the most load, the most marginal load added every year, and the cheapest retail power. Load grew 15% in the 5 years to 2024, and retail prices fell by 1¢.

phil212• 1 month ago

Solar and wind would make it worse.

What matters is peak capacity. Using the grid as a free battery for when your intermittent sources of energy go away against your fairly constant loads only makes the grid weaker overall. The best part of these huge predictable load centers is utilization factor.

Storage of some sort would probably help some, but overall the best type of load for a grid is predictable constant usage. Bonus points if it can reasonably be part of a load shedding/demand response program.

DoctorOetker• 1 month ago

Some kind of large aerostat / inflatabe chimney reaching up till the tropopause largely insulating for most of its length, but with heat engines on top and on bottom. I'm not proposing to use water / ice transition, but just consider a hypothetical strong suspension system, heaving a bucket of water weighing 1 mass unit can be powered by lowering a bucket of ice weighing 1 mass unit (ignore tiny density difference). So one can simultaneously bring 2 thermal baths close together, both at the bottom of the heat loop (where ambient temperature and tropopause temperature in the loop are close by each other) as well as at the top (where ambient cold tropopause temperature and surface temperature in the loop are close by each other). So both at the top and the bottom mechanical power can be generated with a heat engine.

The ground level vs tropopause temperature difference is not perfectly stable but largely maintained throughout day and night cycles, it is effectively base load, no nuclear required! We could generate energy while helping the planet cool.

Best to place these in seas, at least 1 structure length away from coastline, not in the middle of densely populated area. Salty sea water can be frozen (purifying it because ions get pushed into the brine) for desalination, brought to conventional thermal power plants, melted on their cold sides producing potable water while improving the thermodynamic efficiency of the thermal power plant (more electric energy per unit of fuel / rod spent).

AnthonyMouse2• 1 month ago

Data centers are pretty useful for adding more renewables to the grid. They generally have both a UPS (for short-term outages) and backup generators (for long-term outages). UPS means they're already paying for inverters and some amount of batteries, and then in combination with a more renewable grid, it makes sense to put the grid storage batteries there, and they have the incentive to do it to take advantage of time of day metering by actually running on them during peak demand hours. Likewise, if you have a huge capacity backup generator and the grid is stressed because renewable generation is low (and therefore prices get high), you can turn it on. Which allows the grid to get more power from renewables the other 95% of the time.

threwrfaway8• 1 month ago

For those who dont know why this is important:

The loads are slowing down the generators that are burning a well metered amount of fuel to stay at 60Hz. This is a delicate balance since the phase angle must also be spot on.

If a generator and the local line disagree on f, phase or V, you have a short circuit.

If you lose a large amount of load, your generator will spin up with the excess fuel until the control system re-establishes the right amount of fuel.

But now your generators are out of sync! No worry, for small disturbances the dissipative losses sync everything up like syncros on a manual transmission.

But the disturance cant be too big!

Rotating machines are big and heavy, so the first line of defense is their inertia. But this is a finite (and precious) resource.

Contrary to belief, renewables, or generally speaking DC, makes things this stability problem worse. They generate large amounts of power while providing no inertia.

You'd think it isn't a big deal since the DC-AC converter can just synthesize whatever is needed. Heck just keep it rigid at 60 Hz with no phase change.

Well the later doesn't work - the rest of the grid is no longer at that phase and frequency so you got yourself a short.

Furthermore, the DC-AC converter, despite their manufacturers' promise, has no good way to establish what f and phase it should be at during a disturbance (and these magic codes are closed source, believe it or not)

Anywho, a large enough loss of load causes the grid to enters into unstable oscillations, causing protective relays to trip causing a zipper effect where the grid goes down.

Now restart will take a few days depending on the energy mix (fastest for hydro heavy)

Long story short - this is not a trivial problem, and the data-centers can't be allowed to just dump load willy nilly.

EDIT: made it clear that the grid killing disturbance is not caused by renewables; not exclusively anyway. Everyone has to play nice or the grid goes down.

TOMDM2• 1 month ago

Would demanding that large spikey users of energy like data centers implement some sort of demand ramping/isolation from the grid in the form of a massive capacitor bank or flywheel generator between them and the grid help reduce the risk here?

manarth2• 1 month ago

The data centres aren't inherently spikey, in general use their consumption is reasonably predictable.

However, if a DC detects that the _grid_ is wobbly (voltage or frequency deviations) the DC will disconnect without warning, and switch to its batteries and generators.

The grid complains because it's suddenly lost hundreds of MW of load. For the DC to have isolation capability, it would need a load-sink which can consume roughly the same power as the DC in normal operation, and can take in that load at a moment's notice.

It's a hard problem to solve, and probably better managed at grid-level than DC-level.

wyldfire• 1 month ago

Some of us in Texas are all too familiar with the problem of balancing load with generation, the risk of a cascade failure causing a slow restart.

During winter storm Uri, they did a duty cycle where we only had power available for ~6-12 hours at a time on the days it was available. This was apparently to avoid that very problem.

So far as I know, the obvious mitigations like winterizing NG generation and/or peering with neighbor grids have not been performed.

namibj2• 1 month ago

10+ MW voltage-source converters that can't do up to around 80% of their nominal capacity as mostly-reactive apparent power with stabilizing synthetic inertia scaled as desired/specified are a mostly software issue, stemming from lack of regulatory pressure incentivizing the engineering complexity of that.

Though if you want to do a smoothing action on real power flux you'll have to colocate battery capacity with the converter. Which to be clear is fairly cheap to do as long as you get compensated for the substantial frequency stabilization capacity this represents. I'm talking like 15~120 minutes at converter nominal AC power of battery capacity.

The first 10~20% of reactive power are almost free from the converter electronics, btw....

nutjob23• 1 month ago

Grid scale battery systems are also used to maintain proper synchronization.

Retric• 1 month ago

That’s a simplified and somewhat outdated version, there’s a huge range of technology to mitigate each of these issues but infrastructure generally isn’t free. A turbine does provides inertia for free where you need to pay for a flywheel or battery system.

In the end a renewable heavy grid can be extremely resilient due to all the batteries, but smart battery systems need to be incentivize or mandated because ‘dumb’ batteries are cheaper.

peterus• 1 month ago

To add on to this overview, there are a new class of inverters in research called grid forming inverters which don't just follow the rest of the grid. One interesting technique is they can simulate the inertia of a traditional rotating machine/generator.

https://iten.ieee-ies.org/journal-featured-article/2025/grid...

jillesvangurp4• 1 month ago

Grid forming batteries and inverters are a thing. They can control the frequency on the grid. Just a matter of getting the right equipment.

The nice thing with data centers is that they are somewhat flexible. It's not a constant load. Data center operators can choose to reduce load. And if properly engineered, they could do so automatically based on signals from the grid.

The issue with outdated grids is that it relies on technology (spinning mass) that's at this point a century old. Which makes it brittle against outages like you describe. The solution is not more spinning mass but batteries and renewables to take the place of that spinning mass. A battery can respond to oscillations in milliseconds. If you then add flexible load that can spin up/down based on the amount of available power, you gain a lot of stability.

Why the spinning mass technology being "century old" (more like "millennia old" but anyways) is a problem somehow? The Newton's First Law didn't change much in the time that has passed.

Anyone who tried to "respond to oscillations in milliseconds" knows how hard that problem is because the force you apply is integrated twice before it takes effect. Try stabilizing a swing by pushing it's forward when it's behind the equilibrium point and pushing it backward when it's ahead of it. Now imagine a grid of swings connected by rubber bands and a distributed system of independent actors responding to oscillations. There are much more ways in which this system can diverge rather then converge.

Time may prove me wrong, but the arguments like "spinning mass is old therefore should be replaced" certainly won't.

When you say "short circuit" - is this when wires get hit and make and burn, or this is reference to some other stuff?

analog31• 1 month ago

Short circuit is when two sources try to drive the same node in a circuit at different voltages or frequencies. In an idealized circuit (such as where the wires are assumed to have zero resistance), current flow from one source to the other is infinite. In a real circuit, current flow rises to a level where "something has to give." This could include heating the wires between the sources or tripping some kind of protection mechanism.

I'm not great with analogies, but imagine a train with two locomotives, and each one is set to run at a different speed. There will probably be a lot of screeching of wheels etc. To make multiple locomotives work on a single train requires engineering them to be synchronized with one another.

somewhereoutth• 1 month ago

So apparently grid forming or synthetic inertia can be provided electronically nowadays, but presumably it would not be too terrible to put a rotating mass in between the (e.g.) solar power source and the rest of the grid? So the electricity from the solar panels runs a motor that turns a generator. I suppose power is lost through friction and other inefficiencies, and you'd need to co-locate the solar panels into a big enough farm.

chaz6• 1 month ago

Is it feasible to tie the grid frequency to an external clock reference, such as TAI?

tenthirtyam• 1 month ago

I've often thought that the target* grid phase should be encoded into a high frequency signal, say at 50kHz. Generators without inertia can immediately switch to the required phase and inertial systems can work towards it or disconnect their outputs if they stray too far.

The problem in my mind is that, as it stands, the signal that everyone has to latch on to is itself affected by load and by different generators latching on with different time constants in a complicated feedback loop. Would having a single authoritative source be an improvement? Would that be a way to eliminate the need for inertia?

*I suppose the "target" phase would probably be based primarily on the output from the biggest inertial systems and take into account their ability to adjust phase and frequency.

bryanlarsen2• 1 month ago

That's not true. Modern batteries and inverters can be really good at providing synthetic inertia.

Proof by example: https://spectrum.ieee.org/grid-scale-battery-scotland

As the article says, this is difficult and adds significantly to the cost. But it is very possible.

(It also adds significantly to the cost of spinning mass generators too. Delivering 250% of nominal current in a short circuit situation requires beefing up a lot of components).

There are many others.

namibj2• 1 month ago

Actually large data centers at least if done in a vaguely alirack style architecture, can do this with a decent fraction of their nominal power for very little hardware cost, as reactive power and real power add up via Pythagoras (`apparent=sqrt(real^2 + reactive^2)`) to the apparent power (rms voltage times rms current, which is what the 60Hz electronics and 60Hz transformers care about). The first 10-ish % are nearly free.

And alirack style datacenters have large 3-phase converters between the grid and some 240 (nowadays often 350) V DC bus, with the battery banks directly (with just fuses and sometimes a little bit of balancing/nudging power (think 10% of battery power rating)) on the bus, and then the servers also directly consuming from that bus.

The large converters on the battery bus thus allow synthetically smoothing load transients to the grid using the batteries to smooth that power draw. This has just minor additional wear on the batteries and a small power efficiency impact from hitting through the batteries, both of which are easily paid by anything market-rate of providing that grid service. Because they already need the power electronics and batteries anyways, unlike a utility battery farm that at best can argue day/night load shifting of solar production as the reason for the electronics and batteries to exist.

In that same spirit it's also effective to put batteries on the DC bus (between MPPT and inverters) of large solar farms, because they need the electronics anyways and it's actually reducing the required inverter&transformer capacity of the solar farm by peak-shaving.

Texan here. Actually, it depends on how hot our summer weather gets and, thus, how much A/C use is in play. When we get into a not-unusual run of multiple 100-degree (F.) days in a row, the available capacity often drops to the point where ERCOT begins issuing alerts about things like suggested times of day when running certain appliances might not be wise. Having lived through the nightmare of the February '21 winter storm outages, I keep the ERCOT dashboard[0] as a bookmark and check it at least once, every day of the year.

Charge them the cost of installing mitigations that can pick up the load if they drop it suddenly.

bob10292• 1 month ago

I'm a bit confused about why this is a serious engineering problem.

If a gigawatt class DC suddenly needs to take its sensitive IT loads off grid, it could be designed with load banks on site to stand in for the IT load. These would be exceptional use only, so the specific cooling technology (obviously we want to boil water) is not much of an ecological concern. A gigawatt will vaporize ~100 gallons of water per second. How long until the grid can adapt? Five minutes? That's not exactly a heroic amount of water for these projects.

burnt-resistor4• 1 month ago

could be designed with load banks on site to stand in for the IT load

Yes, but that's not what's happening. These giant loads are suddenly going offline and are making it the transmission and generation networks' problem. The DCs aren't going to pay for it when they can socialize the costs and problems onto others.

The most obvious answer is these big loads need FFR and M-FFR BESS (battery) capacity near them or on-site to decouple and absorb these huge transient load swings into something the grid can handle. ERCOT should set additional rules that large load customers must use load smoothing rather than simply dumping load at auto-reclosers/auto-cutouts. Not doing so forces the entire grid to be at risk of low inertia transient over-generation.

ProllyInfamous• 1 month ago

why is[/]this a serious engineering problem[?]

Because the Texian grid-operator (ERCOT) is predominantly isolated from the Eastern & Western US grids [†], serving mostly-just Texans – this is to avoid US Federal regulations, by being an only-intrastate entity (technically, which is: the worst kind of "correct" [∑]). This is a socially-engineered "problem".

This means their needs for maintaining grid inertia (which frequency is a measure-er of) are more difficult, as Texas cannot just purchase any substantial/meaningful electricity – everything must be generated in-house.

Worse, the lack of Federal regulations means ERCOT/Texas can create their own rules/regulations/markets for the management of electrical infrastructure. Texas chose to make (IMHO) the most-purely crony-capitalistic market [for buy/sell of MWhours] in worldwide existance – which leads to decannual winterstorm Disasters (totaling hundreds of BBillion$ in damages / hundreds dead). The losses from wasted silicon-ingot depositions (alone) are staggering $,,,.00 – just another cost of doing business within Texas's jurisdiction [ß].

After 2021's storm, some "free market" customers were left with a week of billing costing more than the year's remainder!.

Abbott will just blame the windmills and not a cost-incentive fee-structure which does not incentivize cold-weather preventative maintainance. In fact, it does the opposite (since electricity can 25X price-increase). "Tell me the incentive and I'll tell you the outcome."

[∑] having grown up and been schooled primarily in Texas, I think the best review I ever agreed with was: "The [L]one Star State" – Texceptionalism will kill us all

[†] small DC-DC grid-ties (altogether a low, single-digit percentage of ERCOT's overall capacity) exist with both grids, as well as another smaller with Mexico

[ß] which is why most hospitals/datacenters have their own diesel/LNG generators, on-site – in Texas these have even less regulations because: "temporary" see (e.g.): Tesla's multiple Texas facilities' backupsystems – enormous point-source pollutors

----

If you want a good breakdown of the 2021 Texas storm's decimation of ERCOT/Texas/electricity, look for the great logs reddit /u/redditmudder did (in realtime) as this disaster was unfolding. I cannot remember exactly how low the frequency got... but I think we were closer to EU [50hz] than US [60hz] – as grid operators REAPED profits* from their failing infrastructure driving electricity orders-of-magnitude higher. This is all public information; it wasn't "windmills."

They aren’t being allowed to connect until they get it worked out. At least that’s how I read it.

ERCOT operates under a “connect and manage” interconnection philosophy. This means things can actually get built quickly (unlike other ISOs), but some management is required.

Of course, there are some downsides to this approach, but overall I think it’s a superior. Just look at renewable and battery penetration compared to other ISOs.

This isn't the US - it's just the state of Texas. The rest of the contiguous United States is on two large grids. Texas has its own.

It's up to ERCOT to figure their own mess out. They will. Nobody else really has to care about it.

Taking note of the risk is important for everyone but shouldn't the follow up action be to improve the grid voltage stabilization mechanisms?

I have no idea of what entails but this seems more a quality of service issue (provided by the grid) and less about the consumers using the grid.

I have read in other contexts that Texas has the least stable power grid in America. It has more downtime than even California, with it's annual wildfires. Despite the regulatory appeal, it does argue against data center expansion in Texas generally.

The problem: multi-GW DCs going suddenly offline leading to rapid transient overproduction.

What's missing is sufficient FFR and M-FFR BESS (battery) capacity to smooth out these sudden disconnects. There's only about 20 GW of BESS generation capacity total in the system now, and ERCOT needs at least 3x more. Placing large FFR and M-FFR near these giga DCs is what it will take to absorb transient overproduction transients from hurting generators or tripping the grid. This is something DCs should pay for rather than upending how the grid works for problems they cause.
