What is a location in between an electrical generating plant and consumers that changes the voltage of the electricity from high to low using transformers?

From the generating "base" to the user the change in the high to low frequency depends on range from in between the two and is changed by a electric power transmission, which is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation.

Between the generating station and consumer, electric power may flow through several substations at different voltage levels. that it
