Calgarians rely on us every day to provide them with safe and reliable power. As our city grows, so do our needs for electricity. At ENMAX Power Corporation, we are committed to providing long-term, innovative solutions to meet the growing demands of our city.
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.
The Downtown Calgary Network System is one of the largest in North America, covering eight square kilometers.
There are more than 982 transformers that are part of the network. These are located in vaults either beneath city streets and sidewalks, covered by grates, or inside of buildings. There are 421 vaults in Calgary.
