NTT Hillsboro Campus

Hillsboro, Oregon, United StatesPartially operational

Planned critical IT: 126 MW
Updated: Oct 29, 2026

NTT markets Hillsboro’s 47-acre campus with 126 MW of planned IT capacity across five centers and HI1 at 36 MW. Lewis describes 138 MW across three facilities—HI1 36 MW, HI2 66 MW and HI3 36 MW—with OEG corroborating HI2. These unreconciled operator/contractor scopes are not commissioned load. HI1 offers closed-loop cooling and Subsea Connect connectivity. County account R685967 lists HI LLC and 47.85 acres in different tax-year sections; linked R2214135 is machinery/equipment, not a second land parcel. The campus is partly operational; full-campus commissioning remains unverified.

Additional project facts

Reviewed h assessor context

Reported rounded

Washington County account R685967, captured on 31 October 2026, lists NTT Global Data Centers HI LLC in its 2027 owner section. It links 4050 NE Evergreen Road and 4510 NE Dawson Creek Drive, map 1N2280002900. Its legal description and 2026 land segments state 47.85 acres. This is tax account evidence, not inspected title or proof all planned buildings share a parcel. The county links it to R2214135, classified Industrial M&E with legal description associated machinery/equipment, using the same map number and HI LLC owner name. That associated account is not evidence of a second land parcel.

Reviewed h exemptions context

Reported rounded

Washington County account R685967 lists an enterprise zone construction in progress exemption entry expiring in 2027 and enterprise zone exemption entries with expiration years from 2027 through 2031. These are account level entries, not a single campus wide term, cash award or established amount of tax savings.

Reviewed h capacity scopes context

Reported rounded

Lewis describes a 138 MW delivery scope across three facilities: HI1 36 MW, HI2 66 MW and HI3 36 MW. OEG corroborates HI2's 66 MW and names Lewis as general contractor. These are contractor attributed scopes, not verified commissioned load or a reconciled replacement for the existing operator attributed campus headline and building count. The scope conflict remains unresolved; no plan revision chronology is established.
