Investment takeaway · Our analysis

The SK–AWS partnership connects cloud demand with construction and energy participants in Korea. Investment value depends on phased delivery, reliable power, financing terms and actual service use. A 15-year partnership and larger corporate capacity aspirations do not reveal a guaranteed project margin.

What the evidence establishes

Groundbreaking and subsequent operator construction disclosures; 41 MW/103 MW remain future phase targets.

Companies and economic roles

AMZN: AWS AI Zone/cloud services partner. SKM: SK Telecom coordinating AI infrastructure; contractual economics unestablished.

Timeline and next milestones

2025-06-20: partnership launch event and ministry project announcement. 2025-08-29: Korean operator release reports groundbreaking ceremony. 2025-10-30: results release describes construction phase. 2026-07-05: operator strategy release still describes Ulsan under construction. 2027-11 and 2029-02: ministry-announced partial and full phase targets, not completion dates.

Resource and capacity boundaries

The ministry announced 41 MW partial operations targeted for November 2027 and 103 MW by February 2029. SK’s July 2026 strategy describes Ulsan as under construction; its wider multi-GW plans are not contracted capacity here. The June 2025 government announcement anticipated September construction, while the Korean August 29 release documents the ceremony. These are separate dated records, not interchangeable completion milestones.

Risks · Our analysis

Power availability, permitting conditions, funding, construction execution, hardware delivery and customer utilization can change economics. A headline capacity figure does not establish billable occupancy, realized prices or site cash flow.

What would change the assessment

Current power-supply authorization and phase capital; 41 MW phase commissioning/customer acceptance; 103 MW phase delivery; broader expansion only with separate evidence.

Unresolved evidence

Exact current financed phase and contract values; Project-specific permits, direct-power authorizations and tariffs; Accepted IT load and GPU inventory; Construction percentage, commissioning and site earnings.

Investor close · Our analysis

Watch the conversion of documented commitments into accepted infrastructure and productive computing. Assess financial implications only when the relevant contractual and operating evidence becomes available.

Sources and claim verification

6 reviewed documents; same-issuer releases and participant-derived reporting are not independent inspections. Government announcements and promotional pages establish only the stated scope. No original interviews or site visits were conducted.

   June 20, 2025 event; KRW 7 trillion project envelope including AWS $4 billion; planned 41 MW November 2027 and 103 MW February 2029. Announcement, not building/energy permit, closed financing or operating acceptance. Korea.net mirror dated June 27, 2025 was not directly fetched; do not count mirror independently.

3. SK Telecom · 2025-08-29

   Reports groundbreaking ceremony with SK ecoplant, AWS and Ulsan city; names proposed power participants. Faithful translation; ceremonial start is not completion. Power-cost advantages are issuer claims; no executed tariff reviewed.
