TITTABAWASSEE
SubstationMichigan · CONSUMERS ENERGY CO
TITTABAWASSEE is an electric transmission substation in Michigan, operated by CONSUMERS ENERGY CO. It is classified as high-voltage (345 kv) and connects 13 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.
