Transmission line vs. distribution line

A transmission line is a high-voltage power line, commonly 69 kV and above in the U.S., that moves bulk electricity from power plants to substations. A distribution line runs at lower voltage, typically below about 35 kV, and delivers power from substations to local customers. Large data centers usually need transmission service through a dedicated substation, while distribution service suits edge sites and small loads.
