Summary
- LG said it would add KRW1.3tn, about USD910m, to the Paju data-centre programme.
- The new commitment more than doubles the KRW615.6bn announced in May 2025.
- LG Uplus is developing a 73,710-square-metre campus with a confirmed planned power supply of 200MW.
- In a 5 June update, LG Uplus put construction progress at about 20%; completion remains targeted for 2027.
- The eventual design is described as capable of hosting more than 100,000 servers, while the first building was reported sold out before completion.
- None of those measures establishes commissioned IT load, live utilisation, customer identities or the final capital cost.
The money has moved further than the buildings
An additional commitment is a real corporate decision. It can release procurement packages, support contractors and cover equipment whose lead times extend well beyond a quarterly budget. The KRW1.3tn is therefore more informative than an aspiration to build “at scale”.
It is still a commitment, not a construction certificate. LG Uplus’s own June account placed the site at roughly one-fifth complete. Spending, contractual commitment and physical progress will not advance at the same rate: deposits may precede delivery, while completed structures may await electrical and cooling equipment.
The public record does not provide a draw schedule or say which packages the extra capital funds. Readers cannot calculate total project cost by simply adding every announced number; prior commitments may overlap with later budgets, and neither source provides a reconciled capital table.
Two hundred megawatts is a supply boundary, not a utilisation reading
LG Uplus says a 200MW power supply has been secured for Paju. That is an important de-risking step in a market where grid access can be harder to obtain than land. It indicates that the project has a power envelope around which buildings and cooling systems can be designed.
It does not say that 200MW is available at every stage, that all of it becomes IT load or that a customer is paying for it. Facility power must serve cooling, conversion losses and other supporting systems. Grid works, substations, testing and building-by-building energisation also sit between a supply agreement and metered operation.
The next useful disclosure would separate utility capacity, commissioned facility capacity, available IT load, contracted IT load and average measured demand. One number cannot perform all five jobs.
Server count is a flexible engineering estimate
More than 100,000 servers sounds concrete but depends on what a server is. A high-density AI rack has different power, cooling and floor requirements from conventional enterprise equipment. The future mix of GPUs, CPUs and other accelerators can materially change how many machines fit inside the same electrical envelope.
LG Uplus says the campus is being designed to support both air and liquid cooling. That flexibility matters because the equipment mix may evolve before the final halls are commissioned. It also means a server-count estimate should not be converted into a fixed compute-output claim.
No source discloses rack density, accelerator allocation or customer workload. The count describes an eventual hosting possibility, not installed inventory.
A sold-out first building narrows one risk and leaves several others
LG Uplus reported that the first Paju building sold out before completion. Pre-leasing can reduce commercial risk and justify procurement. It may also help align equipment delivery with known demand.
The phrase does not publish the tenant, contracted megawatts, term, price, cancellation rights or conditions tied to energisation. A building can be commercially allocated while still facing construction, commissioning and grid milestones. Revenue recognition may follow another schedule again.
The company’s KRW5tn cumulative AIDC order ambition for 2030 is similarly a target. It belongs in a commercial plan, not in a table of realised Paju revenue.
Paju adds concentration to LG Uplus’s operating model
LG Uplus already operates ten data centres in South Korea, according to the company information cited by Data Center Dynamics. Paju is different in planned scale and in its orientation toward high-density AI infrastructure.
That creates an operating challenge as well as an opportunity. Hybrid cooling, high-voltage equipment and concentrated customer loads make maintenance discipline and staged commissioning central. An incident in one large campus can carry more customer consequence than a similar component failure in a smaller site.
Existing operating experience helps, but it does not prove that a new design will meet its intended efficiency or availability. Those outcomes require commissioning records and operating data.
The 2027 milestone needs a conversion table
The target year should eventually be divided into building completion, power-on, acceptance testing, customer handover and first paid load. A campus can be “completed” under one definition while halls remain unoccupied or later phases continue.
Investors need a reconciled capital budget and evidence that procurement stays on schedule. Customers need dates for usable capacity and cooling specifications. Grid stakeholders need the ramp in actual demand rather than the nameplate envelope.
The additional KRW1.3tn makes Paju more credible as a funded programme. The harder proof will arrive when LG Uplus shows how much of the 200MW has passed through construction, commissioning, contracting and metered use.
