At a glance

SHUTTLE is a 66 kV electric substation in California on SOUTHERN CALIFORNIA EDISON's transmission network, recorded in the HIFLD transmission dataset. 3 transmission lines connect to it. 1,504 of California's 3,003 named substations operate in a higher voltage band. The highest-scoring datacenter candidate site within about 25 miles is STATION M(VALLEY) in Los Angeles County, with a DC Readiness score of 62/100.

SHUTTLE is an electric transmission substation in California, on SOUTHERN CALIFORNIA EDISON's transmission network. It is classified as distribution (<69 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.
