​​Substations keep reliable electricity available for customers

The purpose of a substation is to ‘step down’ high voltage electricity from the transmission system to lower voltage electricity so it can be easily supplied to homes and businesses through our distribution lines.

ENMAX Power Corporation operates 40 high voltage electrical substations and three lower voltage distribution substations, located in​ all parts of Calgary and our surrounding service area.
