Washington data centers, in short
Washington has 112 data centers identified from primary sources, spread across 26 cities and counties and run by 47 operators. The largest concentration is Quincy, with 25 data centers, followed by Seattle with 25 and Tukwila with 13.
The operators with the most data centers in Washington are Sabey (7), Microsoft (6), Digital Fortress (6), IsoFusion / Colocation Northwest (5), Ziply Fiber (4). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings.
Not every operator discloses size. In Washington, 24 publish a floor area and 23 publish a power figure, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced.
NON-RTO There is no RTO or ISO market in Washington, so each utility and the state commission set interconnection terms. 2 statewide measures governing data centers are on record, alongside 5 local pauses. 4 named projects in Washington are delayed, blocked or under challenge, and the capital atlas records 7 sites here.
