Provider notes
Energy. In Pacific Power (PacifiCorp) service territory (utility inferred from territory, not company-confirmed); regional supply is hydro-dominant.
Water. Amazon's Aug 2026 community materials state the cooling system will use outside air ~93% of the year, with water-based cooling supplementing during the hottest ~7%.
Community. Port of Walla Walla commissioners approved the amended land sale unanimously (Feb 12, 2026), calling the project transformative; documented concerns from the Confederated Tribes of the Umatilla Indian Reservation (sacred Snake/Columbia confluence), environmental and academic voices, and a commissioner over water and power. No litigation or moratorium; a SEPA environmental review with tribal and public comment is still pending.
These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.
- Announced investment: The source note says the roughly $4.8 billion campus figure is an estimate across about four phases, not a firm pledge, and was meant to be omitted as an investment value.
What the source record says
~$4.8B, ~300 MW campus near Wallula, Walla Walla County; operator reported (not officially confirmed) to be AWS → confidence reported. Coordinates are the Wallula area centroid. Operator confirmed as Amazon Data Services when the Port of Walla Walla amended the buyer from Advance Phase LLC to Amazon Data Services (Feb 12, 2026 commission vote; >550 acres for >$36M land) — confidence upgraded to confirmed. The reported ~$4.8B (DCD) / ~$5B (local) campus figure is an estimate across ~4 phases, not a firm pledge -> investmentUsd omitted. Port projects ~720 direct+indirect jobs at full build-out (projection) -> jobs honest-zero. Eligible for Washington's rural-county server-equipment sales/use-tax exemption (RCW 82.08.986) but no DOR certificate is confirmed -> subsidy honest-zero. Water source and cooling type are undisclosed pending SEPA (no water rights were conveyed in the land deal).
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
Status history supplied by the source
- 2026 · source-reported under construction
A ~$4.8B, ~300 MW data center in Walla Walla County (Wallula), widely reported to be AWS
- 2026-09-05 · source-reported proposed
Walla Walla County's own project page and local reporting show the campus is still in permitting, not construction. The county held a pre-application meeting on April 29, 2026, issued a Notice of Incomplete Application on June 23, 2026, and issued a Notice of Complete Application on August 24, 2026 (files SDP26-01 and SEPA26-05). As of September 1, 2026 no final land-use decision has been made and construction has not been initiated. The record's current 'under_construction' status is not supported by these sources.
