TILLAMOOK

Substation

Oregon

Max voltage
230
kV

TILLAMOOK is an electric transmission substation in Oregon. It is classified as high-voltage (230 kv) and connects 6 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.

Dataset updated . Screening estimates derived from public data sources.

Substation attributes are derived from public HIFLD / EIA infrastructure data and may lag real-world upgrades or retirements. Voltage and connected-line counts are screening figures — confirm available capacity and interconnection terms directly with the operating utility and ISO.
