This is the Hermiston campus inside the city limits, and that boundary is why its electricity supply needed a regulator's signature. Hermiston Energy Services, the municipal utility, would normally serve 908 East Penney Avenue; instead it agreed a customer allocation letting Umatilla Electric Cooperative take Amazon Data Services, announced jointly on 22 June 2020, ratified locally by city Resolution 2208 in January 2024 and approved by the Oregon Public Utility Commission as Order 24-140 on 20 May 2024. Both utilities buy wholesale power from the Bonneville Power Administration. Hermiston's own economic opportunities analysis counts eight data centre buildings across roughly 215 acres on this campus and the Lind Road site together. The city recorded a major partition for Amazon Data Services on tax lot 4N2823 TL 200, conditioned on improving the East Penney Avenue frontage, and annexed a further 810 acres of industrial park in late 2025.

Why did the supply arrangement need PUC approval?
The campus sits inside Hermiston city limits, which is Hermiston Energy Services territory. Moving Amazon Data Services onto the cooperative required a territory allocation agreement, filed jointly on 27 February 2024 and ratified locally by Resolution 2208.
Where does the power ultimately come from?
Both Hermiston Energy Services and Umatilla Electric Cooperative take wholesale supply from the Bonneville Power Administration.
How many buildings do Hermiston's Amazon campuses hold?
Eight across roughly 215 acres, counting the Penney Avenue and Lind Road sites together. The city's economic opportunities analysis publishes the figure combined rather than per campus.
Which parcel does the city record?
Tax lot 4N2823 TL 200 at 908 East Penney Avenue, subject of a major partition for Amazon Data Services Inc carrying a condition to improve the East Penney Avenue frontage.
