At a glance

CALAPOOYA is a 230 kV electric substation in Oregon on PACIFICORP's transmission network, recorded in the HIFLD transmission dataset. 3 transmission lines connect to it. 34 of Oregon's 554 named substations operate in a higher voltage band. The highest-scoring datacenter candidate site within about 25 miles is ALVEY in Lane County, with a DC Readiness score of 69/100.

CALAPOOYA is an electric transmission substation in Oregon, on PACIFICORP's transmission network. It is classified as high-voltage (230 kv) and connects 3 transmission lines. Substation proximity is one of the strongest speed-to-power signals for siting a datacenter — interconnection distance to an energized, high-voltage bus is often the binding constraint on time-to-energization.
