The Winston Heights–Mountview Powerline Committee is continuing to monitor Enmax’s planning process for the transmission line replacement. Here’s a summary of the latest developments.
Enmax Consultation Sessions
Committee members attended both Enmax consultation sessions and spoke with residents about the project. Almost 90 people turned up for both sessions – we added several new contacts to our mailing list.
Highlights
• Some attendees reported hearing that undergrounding the line would cost “eight to ten times more” than an overhead route. Enmax’s earlier figures suggested an increase of about 25%, not 800 to 1,000%. We will continue watching for inconsistent or inaccurate information as consultation continues.
• Strong opposition to a route option for 20 Ave.
• Strong support for a route along 16 Ave or underground through the community.
AUC Application Process
Because the Alberta Utilities Commission declined Enmax’s first application, all route options are back on the table. ENMAX is reviewing possible routes along:
• 16 Avenue
• The alley south of 16 Avenue
• 17 Avenue (overhead or underground)
• 18, 19, and 20 Avenues
The endpoints—Substation 3 and Nose Creek Valley—stay the same; only the route between them may change.
Consultation Timeline
ENMAX shared the following schedule:
• December 2025: Public input sessions
• Q1 2026: Route concepts presented for feedback
• Q2 2026: Preferred routes shared
• June 2026: New application submitted to the AUC
A final AUC decision is expected in 2027.
Why This Matters
The expanded study area reaches up to 20 Avenue, meaning many parts of Winston Heights–Mountview could be affected. Please stay informed and take part in consultations so our community’s concerns are clearly represented.
Enmax Online Survey
If you haven’t yet completed the Enmax survey, please take a few minutes to do so—your input matters.
Next Steps
Once Enmax confirms which route options will be included in their new application, the committee will decide whether to act as interveners again. If we do, McLennan Ross LLP will represent our community.
