Switchyard
A switchyard is an outdoor arrangement of circuit breakers, switches and buswork, operating at transmission voltage, that connects lines together or ties a facility into the grid without necessarily changing voltage. For data center campuses, the utility often owns a switchyard where the transmission line terminates, next to a customer substation that steps voltage down. Both need land, access and line routes.
