Data Center Investment in Seattle

Seattle's data center market sits at the epicenter of West Coast tech demand. Amazon, Microsoft, and Meta's massive presence drives hyperscale requirements while enterprise colocation needs keep growing. Power's getting tight. Fiber connectivity is world-class. Cap rates hover in the low 4s for hyperscale, mid-4s to low 5s for enterprise colocation. AI workloads are pushing power density through the roof – some facilities now spec'ing 30-50kW per rack. If you're packaging a data center deal here, power availability documentation makes or breaks your story.

What Your OM Needs to Address

Power Infrastructure Detail

Document total MW capacity, available MW, redundancy level (N+1 vs 2N), UPS runtime, and generator fuel capacity

Data to Include

Utility provider letters, electrical single-line diagrams, load bank test results, PUE measurements by season

Cooling System Specifications

AI workloads generate massive heat - buyers need cooling capacity per rack and expansion capability

Data to Include

Cooling tonnage, rack density limits, hot/cold aisle containment, chilled water plant capacity, future expansion space

Fiber Connectivity Map

Show all carriers on-net, diverse fiber entry points, and latency measurements to key destinations

Data to Include

Carrier list with bandwidth options, fiber route diversity, latency to AWS/Azure/GCP regions, international connectivity

Tenant Credit and Lease Terms

Data center leases often 10-20 years with complex escalations and power pass-throughs

Data to Include

Tenant credit ratings, lease expiration schedule, escalation formulas, power markup terms, expansion rights

Utility Rate Analysis

Power costs are 40-60% of operating expense - rate trends affect NOI projections significantly

Data to Include

Current utility rates, demand charges, power factor penalties, rate case history, renewable energy credits

Regulatory and Zoning Compliance

Seattle has increasingly strict environmental requirements for data centers

Data to Include

Special use permits, environmental impact assessments, water usage reporting, carbon offset requirements, expansion limitations

Investment Outlook

Short Term

AI demand surge continues driving rental growth of 20%+ annually for high-density space. Cap rates stable in low 4s for hyperscale, may compress further if institutional capital allocation to data centers accelerates. Supply constraints in primary markets pushing development to secondary locations.

Medium Term

Power grid limitations become binding constraint by 2027-2028. Facilities with secured utility capacity command significant premiums. Edge computing deployment accelerates, creating demand for smaller metro-area facilities. Cooling technology advances allow higher rack densities.

Long Term

Seattle remains West Coast hyperscale hub but growth rate moderates as power constraints force expansion to other markets. Existing facilities with expansion capability and secured power allocations see strongest appreciation. Regulatory pressure on energy consumption may impact operating costs.

Buyer Profile

Hyperscale tenants (Amazon, Microsoft, Meta) direct ownership increasing. Digital infrastructure REITs (DLR, EQIX, CCI) active acquirers. Private equity infrastructure funds targeting stabilized assets. Foreign institutional capital drawn to mission-critical tech infrastructure.
