At a glance

NTCQ is a 66 kV electric substation in California, recorded in the HIFLD transmission dataset. 0 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 MIGUEL in San Diego County, with a DC Readiness score of 61/100.

NTCQ is an electric transmission substation in California. It is classified as distribution (<69 kv) and connects 0 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.
