ENMAX No. 31 Substation Upgrades

Project Overview

ENMAX Power Corporation (ENMAX) is proposing to retrofit existing distribution feeder breakers at ENMAX No. 31 Substation located at 3515 – 80 Avenue SE. This will require expansion of the current building approximately 10 metres west to accommodate installation of additional 13.8 kV feeders and underground ducts for feeder cables. All work will be conducted within the substation fence line. These feeders are driven by customer growth and the need to maintain reliability of power supply in southeast Calgary.
