The Pacific Northwest has become one of the largest hyperscale data center build regions in North America. Microsoft Azure anchors a multi-campus footprint at Quincy WA (Grant County) plus Moses Lake. Amazon Web Services runs the largest cluster of US data centers outside Northern Virginia across Boardman, Umatilla, and Hermiston OR. Google Cloud has operated at The Dalles OR (Wasco County) since 2006 and continues to expand. Meta/Facebook and Apple both run flagship campuses at Prineville OR (Crook County), with Meta's facility ranking among the largest in their global portfolio. The Hillsboro OR data center alley, anchored near Intel headquarters in Washington County, rounds out the corridor.
Three structural advantages drive the concentration: cheap hydroelectric power from the Columbia River system (Grant County PUD delivers single-digit-cents-per-kWh rates to Microsoft Quincy); cool, dry climate that lets evaporative and free cooling work efficiently year-round (lowering PUE versus humid climates); and low natural disaster risk combined with extensive fiber to Seattle, Portland, and Bay Area peering points. The 2024-2026 hyperscaler AI infrastructure expansion has accelerated PNW build pace materially.
A hyperscale data center build cycle generates exactly the freight categories Evergreen Shippers brokers best: oversize and superload transformers, backup generators, switchgear, chillers and cooling towers, prefab modular data hall sections, structural steel, and construction equipment. Flatbed, step deck, Conestoga, multi-axle RGN with jeep + booster for the heaviest transformer moves. Permit coordination across WSDOT, ODOT, ITD, MDT for multi-state superloads. Pilot car and police escort dispatch in-house.
Evergreen Shippers (FMCSA MC#896325) is the Spokane-anchored freight brokerage that dispatches this work. Heavy haul and oversize permits are core competencies; flatbed and step deck / RGN / lowboy are the everyday equipment mix. Construction equipment freight overlaps directly.
Six major destinations anchor the PNW hyperscale freight corridor. Each campus runs continuous construction phases on overlapping 2-3 year cycles.
Grant County WA has been Microsoft's signature data center concentration since 2007. Multiple campuses, multiple build phases, growing. Cheap hydroelectric power from Grant County PUD plus Columbia Basin climate. Moses Lake hosts Microsoft secondary footprint plus other tenants. The freight cycle runs year-round with continuous MEP phase delivery.
Amazon Web Services operates the largest cluster of US data centers outside Northern Virginia across Umatilla County and Morrow County OR. Boardman is the anchor; Umatilla and Hermiston satellites continue expanding. Port of Morrow provides barge access to Columbia River for limited freight modes. Active construction continuous since 2011.
Google's longest-operating data center campus (Wasco County, operational since 2006). Repeated expansion phases over nearly two decades. Smaller-footprint than the eastern OR AWS cluster but continuous construction-phase freight tendering. The Dalles also serves as a Columbia River barge access point for limited freight.
Crook County OR hosts both Meta/Facebook and Apple flagship campuses. Meta Prineville is among the largest data centers in Meta's global portfolio. Apple Prineville opened in 2014 and continues to expand. The combined GC + sub-contractor + MEP equipment freight volume into Crook County is among the densest in central Oregon.
Washington County OR — near Intel headquarters — runs an urban data center alley with Digital Realty, Equinix, Vantage, and others operating co-location and hyperscale infrastructure. Smaller per-campus footprint than the eastern OR clusters but high density of operators and continuous incremental construction. Freight runs heavier on switchgear and IT equipment, lighter on superload transformers.
Smaller hyperscale and co-location markets in East Wenatchee WA, Coeur d'Alene ID, and Boise ID round out the PNW corridor. Less construction-phase volume but consistent operations-side freight (server replacements, infrastructure refresh, fiber). Spokane sits centrally between Quincy and Coeur d'Alene with daily routing access to all major PNW data center destinations.
Six phases. Each tenders different freight categories at different volumes. The MEP phase (6-12 months) is the heavy-freight phase where most superload activity concentrates.
Construction-phase timeline assembled from industry standard data center build sequencing as documented by Construction Dive, ENR, and Data Center Knowledge. The MEP phase is the heavy-freight phase where superload transformer and generator deliveries concentrate.
A 230 kV substation transformer for a hyperscale data center typically weighs 400,000 lbs, measures 14' tall, 13' wide, and 30' long. It is the single biggest piece of freight a data center build requires — and the freight item that makes or breaks construction-phase schedule. A delayed transformer delays everything downstream of the substation electrical commissioning.
The freight specification:
Top transformer OEMs that ship into the PNW hyperscale build: Hitachi Energy (formerly ABB Power Grids), Siemens Energy, GE Vernova, Eaton, Schneider Electric, WEG, Howard Industries, Pennsylvania Transformer, Niagara Transformer, Virginia Transformer. Manufacturing origins span Mexico, Texas, Pennsylvania, and overseas — long-haul superload routing is the norm.
See our oversize / overweight permits page for the full state-by-state permit framework and pilot car coordination capability. The transformer freight playbook is the same playbook we run for wind turbine components, industrial heat exchangers, and process equipment.
Pad-mount, substation, generator step-up. From flatbed (30K lbs) up to permitted superload (400K+ lbs) on multi-axle RGN with jeep + booster. Hitachi Energy, Siemens Energy, GE Vernova, Eaton, Schneider Electric, WEG.
Diesel and natural gas standby generators — 2-3 MW class typical, can reach 5+ MW for hyperscale. Caterpillar, Cummins, MTU/Rolls-Royce, Kohler, Mitsubishi. Smaller flatbed; larger multi-axle. Peterson Cat (Sumner WA, Portland), NC Machinery (Tukwila WA), Cummins Sales & Service.
Medium-voltage switchgear cabinets, distribution panels, motor control centers. Flatbed or step deck. Hitachi Energy, Siemens Energy, GE Vernova, Eaton, Schneider Electric. Lead times 12–36 months post-COVID and still elevated.
1,000-2,000 ton chillers (oversize flatbed for larger units), air-cooled chiller arrays, cooling tower modules, CRAH/CRAC units, evaporative cooling for water-side economizers. Vertiv, Stulz, Schneider Electric, Carrier, Trane, York, Liebert, Munters.
Uninterruptible power supply battery rooms, flywheel UPS systems, battery cabinets. Vertiv, Schneider Electric, Eaton, ABB. Flatbed delivery typically; multi-piece consolidated loads for battery cabinet arrays.
I-beams, columns, joists, decking. Cascade Steel Rolling Mills (McMinnville OR), Pacific Coast Steel (Renton WA), Nucor and other regional service centers. Standard 48' / 53' flatbed, step deck for longer columns, sometimes oversize for column lengths exceeding 80'.
Ready-mix concrete from regional plants (Cemex, CalPortland, Knife River, Lehigh Hanson). Rebar from Pacific Steel Group, Nucor, and out-of-region producers. Post-tensioning cable for slab construction. Flatbed and dump.
Data hall sections built off-site and trucked in. 53' flatbed for standard-length modules; oversize permits required for larger sections. Prefab yards in Sumner WA, Boise ID, Salt Lake UT, and California consolidate modular shipments into PNW data center sites.
Pre-cast concrete tilt-up panels for building envelope. Often manufactured on-site at large data center campuses, but external supply runs via oversize flatbed for the longest panels. 250-ton-plus mobile cranes set the panels in place.
National and regional GCs active in PNW hyperscale construction. Most run continuous build programs across multiple hyperscaler campuses simultaneously.
Equipment OEMs and steel mills nationwide ship to six anchor PNW destinations. Spokane sits centrally with daily routing access.
Lane structure based on hyperscaler campus footprints (Microsoft Quincy / Moses Lake, AWS Boardman / Umatilla / Hermiston, Google The Dalles, Meta + Apple Prineville, Hillsboro alley) and major OEM / steel service center / modular yard supply chains feeding the PNW build corridor.
Manufacturing lead times extended to 12-36 months post-COVID and have not fully normalized. Freight scheduling has to align with manufacturing release dates — not the other way around.
We commit carrier capacity to the OEM's expected ship date, not load-by-load. Multi-axle RGN with jeep+booster carriers booked 4-12 weeks ahead for the heavy MEP phase.
Only a fraction of US carriers run multi-axle RGN with jeep+booster configurations capable of 400K+ lb loads. During construction surge periods, the available pool books out weeks in advance.
Heavy haul carriers vetted and contracted ahead of project tenders. Superload, route survey, pilot car, and police escort coordination handled in-house.
WSDOT, ODOT, ITD, MDT each have different superload permit workflows, lead times, and pilot car requirements. Multi-state moves require parallel permit submissions and route synchronization.
Permits pulled across WSDOT, ODOT, ITD, MDT as part of the brokered move. Bridge ratings, route surveys, utility coordination handled before dispatch. See our oversize / overweight permits page.
Temporary site roads, weight restrictions on access bridges, gravel-pad staging areas. A 400K+ lb transformer cannot deliver to a site with a 60-ton bridge rating without temporary structural reinforcement.
Site access route validated with GC and site superintendent before dispatch. Temporary bridge reinforcement, staging area access, and crane positioning coordinated upstream.
500-ton-plus mobile cranes are in tight supply during peak construction season — especially when multiple hyperscale campuses run MEP phase simultaneously across the PNW corridor.
Transformer ETA coordinated with GC's crane schedule. Daylight-only permit travel adjusted to match crane availability window. No "delivered and waiting" days on $1M+ equipment.
Hyperscale campuses run multiple build phases simultaneously. The freight cycle is effectively continuous across a 5-10 year campus expansion arc — not a one-time delivery.
We build multi-year relationships with returning GCs and hyperscaler project managers. Carrier capacity reserved for repeat-customer campuses across full build cycles.
