LAMAR
SubstationColorado · TRI-STATE G & T ASSN, INC
LAMAR is an electric transmission substation in Colorado, operated by TRI-STATE G & T ASSN, INC. 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.
