ENMAX No. 1 Substation Replacement Project

Project Overview

ENMAX Power Corporation (ENMAX) is proposing to replace the ENMAX No. 1 Substation (the Project). The ENMAX No. 1 Substation, currently located at 738 9 Ave SW, was built in 1912 to power streetlights and the streetcar rail system in the downtown Calgary area.  Over the last 100+ years ENMAX has expanded and upgraded the ENMAX No. 1 Substation to meet load growth requirements, such that it now provides power to approximately 45 per cent of the downtown Calgary area.

The proposed Project is needed to ensure the reliability and integrity of ENMAX’s transmission system, and to ensure the reliable supply of electricity to the City of Calgary. The Project is also required to mitigate maintenance and operational safety concerns for workers related to the aging equipment in the existing substation.
