AI Data Centers Are Rewriting Location Value in Real Estate
AI is turning data centers into the anchor asset class that pulls capital, permits, and grid capacity into one place. The result: big tech becomes the long-lease tenant, private equity owns the boxes, and location value is now priced by electrical capacity and cooling efficiency, not commute times.
A recent report from Korea Housing Finance Corporation outlines the shift: hyperscale facilities demand huge land parcels, high-grade energy infrastructure, and specialized development. That combination is accelerating a new division of roles in the market-and opening real opportunities for regional cities that can reuse existing industrial infrastructure.
Follow the Money: Big Tech Leases, PE Owns
Building a single hyperscale site commonly costs 500 billion to 1 trillion won across land, construction, and equipment. If a large platform company funds and holds those assets, return on invested capital takes a hit. Their cash is better spent on models and accelerators than concrete and chillers.
That's where large private equity platforms step in. The model is simple: sale-leaseback or forward funding, 10+ year leases, and a specialized developer/operator that secures grid connections, land, and permits. With high-credit tenants, funds often target double-digit annual returns while tenants preserve capital flexibility.
The New Site-Selection Checklist
- Electrical proximity: Near 154 kV or 345 kV substations, with room for future load. Time-to-energize now drives the deal.
- Cooling advantage: Naturally cool climates and abundant water sources cut energy use and opex; design for water reuse and discharge compliance.
- Resilience: Low seismic and flood risk; strong soil conditions for heavy equipment and tanks.
- Social license: Low local opposition and a clear path through zoning, environmental review, and community benefits.
- Fiber routes: Diverse, low-latency paths to major network nodes and cloud on-ramps.
If any one of these is weak, expect either higher capex, longer schedules, or both.
Why Regional Cities Suddenly Make Sense
One of the biggest bottlenecks is building new transmission lines and towers. That takes years. Many aging industrial parks already have substations, feeders, and easements-meaning faster energization with fewer fights.
That's the opening for regional cities: reuse what heavy industry left behind. It's cheaper, faster, and far easier to justify to stakeholders than carving new corridors through populated areas.
Field-Ready Examples in Korea
- Yeongdo-gu, Busan: An idle shipyard site (Masstek Heavy Industries, Daepyeong-dong) kept its industrial-grade electrical backbone. A developer leveraged that to deliver an ~80 MW class facility-no multi-year wait for new lines, just plug into what was already there.
- Chuncheon, Gangwon: Deep water from Soyang Dam is used for water-based cooling, sharply lowering cooling energy use. Access to hydropower sources has already drawn Naver and Samsung SDS to the area.
- Haenam, South Jeolla: The country's largest solar complex enables immediate consumption of on-site generation. In early January, the province and county signed a business agreement to build an energy-specialized AI data center there.
What Developers, Municipalities, and Lenders Should Do Next
- Map electrical headroom: Identify 154/345 kV nodes, available MVA, and realistic energization timelines. Pre-arrange grid upgrades where necessary.
- Audit dormant industrial sites: Substations, duct banks, water intake/discharge, and road load ratings often exist already-document it and price the reuse.
- Engineer for thermal efficiency: Validate year-round water availability, temperature profiles, and permits. Set PUE/WUE targets early and align them with utility pricing.
- De-risk permitting: Lock in zoning, environmental approvals, and community benefits ahead of tenant RFPs. Pre-zoned, shovel-ready land wins.
- Structure durable leases: 10-20 year terms, expansion options, CPI-linked escalators, and clear handback conditions. Tenants want speed; owners want yield certainty.
- Plan energy strategy upfront: On-site renewables, demand response, and storage can reduce volatility and improve uptime. Tie these to measurable cost savings.
- Secure water rights and redundancy: Clarify abstraction limits, seasonal variability, and backup sources. Cooling reliability is as critical as electrical capacity.
Urban Regeneration, Done with Infrastructure
Data centers were once dismissed as "energy hogs." That view misses the point. When aligned with existing grid assets, water access, and industrial land, these facilities become anchor tenants that stabilize tax bases, spin up local construction, and attract a second wave of suppliers.
Regional cities that move first on permitting, grid agreements, and community engagement can turn stranded industrial capital into AI infrastructure-with real jobs and long-term leases to show for it.
Risk Notes You Should Underwrite
- Grid congestion: Greater Seoul faces tight capacity and long interconnection queues. Model schedule risk conservatively.
- Environmental limits: Water intake, thermal discharge, and noise can constrain design envelopes; permit risk is real.
- Technology refresh cycles: Rack density keeps rising. Plan for higher heat loads and retrofit pathways.
- Exit visibility: Ensure lease flexibility and expansion rights to protect value if tenant needs shift.
Why This Matters for Returns
With investment-grade tenants and long leases, PE-backed platforms can target 10%+ annual returns. The spread comes from solving the hard parts-securing grid capacity, water, land, and permits-before anyone else.
For lenders, covenant discipline on energization milestones, capex reserves, and tenant credit is key. For municipalities, pre-permitted sites and reliable timelines turn interest into signed leases.
