> the Dutch power grid is at capacity and its managing company is now telling companies that planned to build a datacenter that they can't be connected to the grid until 2030, even though said companies already paid for and got guarantees about that connection. Are the Netherlands a large proportion of global datacenters?

Is that relevant? The grid in every country is getting ridiculously stressed by datacenters.
- AnthonyMouse 6mo ago
  What the grid looks like in different countries is very different. The Dutch power grid is already almost 50% renewables, which is an inconvenience for adding capacity because that's around where you have to start really dealing with storage in order to add more. In most other places the percentage is significantly less than that and then you can easily add more of the cheap-but-intermittent stuff because a cloudy day only requires you to make up a 10% shortfall instead of a 50% one, which existing hydro or natural gas plants can handle without new storage when there are more of them to begin with.

    I don’t think the source of the electricity is particularly relevant to whether or not you have the transport capacity to add tens of megawatts of demand to the grid. The problem is generally not the supply but whether your local transformers have capacity left.
    - AnthonyMouse 6mo ago
      When you're talking about something that draws megawatts existing transformers are pretty irrelevant because you're going to run high voltage lines directly to the site itself and install new dedicated transformers on site. What's more common is that they don't have the transmission capacity itself, but that one's pretty easy in this case too, because what that means is that you have an existing transmission line which is already near capacity with generation on one end and customers on the other. So then you just build the data center on the end of the transmission line where the generation is rather than the end where the existing customers are, at which point you can add new generation anywhere you want -- and if you put it near the existing customers you've just freed up transmission capacity because you now have new customers closer to the existing generation and new generation closer to the existing customers.

    > The Dutch power grid is already almost 50% renewables I was a bit stunned when I read this. Your estimate is very close for 2025 here: https://en.wikipedia.org/wiki/Electricity_sector_in_the_Netherlands https://en.wikipedia.org/wiki/Electricity_sector_in_the_Neth... I calculate about 43.5% was solar or wind. What is way crazier is the "bend in the curve" of production sources in the last 10 years. Look here at how fast solar and wind is growing! https://en.wikipedia.org/wiki/File:Netherlands_electricity_generation_by_source.png https://en.wikipedia.org/wiki/File:Netherlands_electricity_g...

  High-level, I would agree with you. One thing that blows me away: I think I read that Northern Virginia, USA has the highest data center density in the world. Mostly it is due to demand from US gov't, military, and spy agencies (like NSA). How did they do it? In mainstream media, I don't see any news about a stressed power grid in this area. I guess the US gov't carefully coordinated with local power providers to continuously upgrade their power grid? This is a real question. It makes no sense to me. No shilling/trolling here.

That's where AWS us-east-1 is, i.e. the oldest AWS region where they got started to begin with. Google and Microsoft also have a large presence there. It's not just the US government, it's everybody, and it's not new. > How did they do it?

Their current power mix is ~30% nuclear, ~12% renewables (solar) and almost all the rest natural gas.

      Well, they have done pretty well for 20 years of planning. Google tells me that AWS us-east-1 region (Northern Virginia) was started in 2006! EDIT The opening paragraph: > State regulators’ review of the controversial power line proposed to stretch across three rural Maryland counties will extend to at least February 2027, officials announced Thursday, a timeline that prevents developers from meeting the grid operator’s deadline to ensure reliable electricity. I bet this is pure NIMBYism. Just this phrase alone is a dead giveaway: "controversial power line". LOL: What is controversial about a power line? Hint: They aren't, but NIMBYism exists.

Yes. Amsterdam has one of the largest IXPs (AMS-IX) in Europe and is also one of the largest European markets for Internet Infrastructure services (i.e. hosting, DNS provision, domain name registration, etc.)

  And all of these are practically irrelevant for AI data centers.
  - crote 6mo ago
    Do AI data centers not need internet connectivity anymore? The value of an IX isn't just in the IX itself, but also in the presence of hundreds of parties for direct peering, and excellent connectivity to the rest of the world. It makes a lot of sense to build your DC near one - even if you have no intention of actually participating in the IX itself.

      > Do AI data centers not need internet connectivity anymore? They don't need entire IX worth of connectivity. You're sending mostly text back and forth and any media is in far lower volume than even normal far less dense DC would generate, all the major traffic is inside the AI DC. All it needs is fiber to nearest IX

Amsterdam hosts a major internet exchange. It's not a bad place to build a datacenter and there are many. Northern latitude brings free air cooling, but also additional distance to clients. Lots of peers in AMS-IX, but not a lot of oceananic cable landings (one with two paths to the US, but most of the submarine cables land nearby in Europe)

  Whether it's generally a reasonable place to build them isn't the percentage. The number seems to be ~3%.
  - AlecSchueler 6mo ago
    3% of the global total does seem surprisingly significant.

      London is about 3X bigger than Amsterdam in terms of capacity. If you look at the core western europe market (so called FLAP-D) which I am rather familiar with London holds 35% of that market and Amsterdam about 12%. I'm not at all sold that the old rule of thumb that this market is about 25% of global capacity has been true since about 2023 because of the AI buildout in NA/ME.
