As AI booms, land near nuclear power plants becomes hot real estate

(2024/03/25)


The land surrounding a nuclear power plant might not sound like prime real estate, but as more bit barns seek to trim costs, it's poised to become a rather hot commodity.

All datacenters are energy-hungry but with more watt-greedy AI workloads on the horizon, nuclear power has fresh appeal, especially for hyperscalers. Such a shift in power also does wonders for greenwashing narratives around net-zero operations. While not technically renewable, nuclear power does have the benefit of being carbon-free, not to mention historically reliable — with a few notable [1]exceptions of course.

All of these are purported benefits cited by startup NE Edge, which has been fighting for more than a year to be able to build a pair of AI datacenters adjacent to a 2GW Millstone nuclear power plant in Waterford, Connecticut.

[2]

According to the [3]Hartford Courant , NE Energy has secured $1.6 billion to construct the switching station and bit barns, which will span 1.2 million square feet in total. NE Energy will reportedly spend an equivalent sum on between 25,000 and 35,000 servers. Considering the price of GPU systems from Nvidia, AMD, and Intel, we suspect that those figures probably refer to the number of GPUs. We've asked NE Edge for more information.

NE Energy has faced local challenges getting the project approved because residents are concerned the project would end up increasing the cost of electricity. The facilities will reportedly consume as much as 13 percent of the plant's output.

The project's president Thomas Quinn attempted to quell concerns, arguing that by connecting directly to the plants, NE Energy will be able to negotiate prices that make building such a power hungry facility viable in Connecticut. NE Energy has also committed to paying a 12.08 percent premium to the town on top of what it pays Dominion for power, along with other payments said to total more than $1 billion over the next 30 years.

But after initially denying the sale of land to NE Edge back in January over a lack of information regarding the datacenter project, it's reported that the town council has yet to tell the company what information it is after.

Taking AI nuclear

While NE Energy vies for approval, other datacenter operators have already furthered nuclear site ambitions or are laying the groundwork to do so. Earlier this month, Amazon Web Services (AWS) [11]agreed to purchase Cumulus Data's atomic datacenters from $650 million.

The datacenter complex AWS is eyeing is owned by Talen Energy is colocated alongside the 2.5 gigawatt Susquehanna nuclear power plant in northeast Pennsylvania. Of that, AWS will have the opportunity to purchase up to 960 megawatts of capacity to support a sprawling datacenter campus. But, if it doesn't need it, it's only required to purchase 480 megawatts of power.

AWS is far from the only cloud provider weighing the nuclear option. Microsoft is actively [12]exploring the use of small modular reactors (SMRs), with the idea being that rather than build datacenters adjacent to existing reactors, it can install tiny modular ones to power existing datacenters.

It should be noted that despite Microsoft hiring folks to explore the application of the tech, no functioning SMRs have been built yet.

[13]

Others exploring SMRs include [14]Standard Power , [15]Green Energy Partners , and [16]Bahnhof . But until SMR vendors, like NuScale, are ready for prime time, there are still more than 400 reactors around the globe to collocate with. ®

Anticipating grid failure is more like it..

cyberdemon

With a functioning grid, there is not much reason for electricity to be any cheaper near to a NPP, surely.

But if the companies are betting on grids failing in future, then nearby to an NPP might be a good spot for their datacentres.

I think in the US NPPs and other generators are allowed to sell direct to customers. In the UK, they can't and have to sell via a sleeve contract so it goes through the 'market', middlemen take their cut and taxes are correctly applied. Something that seems to get overlooked with 'ideas' like using wind to make H2 etc.

"Something that seems to get overlooked with 'ideas' like using wind to make H2 etc."

Not overlooked at all.

There are plenty of issues with hydrogen as long term storage, but "currently you can't sell electricity direct" isn't one of them.

Unless you're close enough (ie collocated) to do a Direct Wire PPA, you're going to be reliant on a sleeving contract. Collocating and arranging a Direct Wire PPA is obviously more challenging with off-shore stuff. Or just intermittent generators like wind & solar in general. But if there's say, a 2GW NPP in the next field, it might make more sense because then the NPP can run at peak efficiency and offload to a Direct Wire client, if required.

You know what's great about legislation - you can change it. The laws of physics, not so much, but contract limitations - absolutely.

Of course you can also do direct PPA, colocate the generation of electricity and hydrogen, or colocate them enough to have a dedicated cable.

"Collocating and arranging a Direct Wire PPA is obviously more challenging with off-shore stuff."

Nigh on impossible. Ofgem's OFTO regulations intentionally make it impossible to use existing offshore transmission technologies for private wire types of arrangement. You could avoid the complex and craply thought out OFTO regulations for offshore power transmission by running below 132 kV. However, for larger offshore wind farms you're typically looking at 220-400kV, so would need much heavier cables for lower voltages along what will often be very long runs. The economics would never work out.

Re: Anticipating grid failure is more like it..

In the UK it's entirely permissible to have "private wire" arrangements for example if you have a factory near a power plant, you can contract with the generator directly and take the power over dedicated power lines you own. That does avoid grid and distribution costs, and most "policy costs" that government require for grid electricity to support their net zero follies.

Curiously, the way the law is written, even under private wire agreements, it is a requirement that you provide wholesale access to your privately owned cables; In practice you'd build the capacity you plan to use between point A and point B, so there wouldn't be any spare capacity to sell.

Yep, which is where the politics and marketing get very bizarre, bordering on fraudulent. So claims of '100% renewable' based on buying REGOs. It also makes for strange economics, ie 'renewables' very much depend on subsidies, and those subsidies can't be claimed for energy sold via private wire PPAs. Also if constraint payments can or should be paid, if energy is still being sold via private PPAs. I also think it's why 'green' H2 can never really work given it would be pretty much dependent on private wire contracts, which then limit the scale and amount of 'green' H2. Plus the costs to transport that to market. I think the 'renewables' lobby is trying to game the virtual PPAs. But they cannae defy the laws of physics, so if there's surplus renewable energy being produced, it can't be shipped via a full grid.

The power generator and grid operator are two different entities in this part of Pennsylvania (Talen Energy and PPL, respectively, in this case). The power is cheaper in this case because the data center is connected with direct feeds to the plant, so no transmission/delivery charges from the grid operator.

Great choice of location
