Dear Winston Heights–Mountview Residents,
The Winston Heights–Mountview Powerline Committee met with Enmax yesterday to receive an update on the Central Calgary Transmission Line Replacement Project. We want to share the key points from that meeting with our community.
New Application Coming
Enmax confirmed that they plan to submit a new application to the Alberta Utilities Commission (AUC) for the transmission line replacement. Because the AUC declined the first application, all route options are once again under consideration.
This means Enmax is reviewing several potential routes, including:
• 16 Avenue
• The alley south of 16 Avenue
• 17 Avenue (overhead or underground)
• 18, 19, and 20 Avenues
The start and end points of the line—Substation 3 and Nose Creek Valley—remain fixed, but the route between them is open for evaluation.
Community Consultation Timeline
Enmax emphasized that they are committed to improving their consultation process with all stakeholders, including our community. They outlined the following timeline:
December 2025: Public sessions to gather general input
Q1 2026: Consultations to present route concepts and gather feedback
Q2 2026: Consultations to present the preferred route options that will be part of the new application
Enmax aims to submit the second application to the AUC in June 2026. The AUC typically takes about ten months to make a decision, so a final decision is likely in 2027.
Why This Matters to Our Community
Because the potential route area now extends as far north as 20 Avenue, this project could affect many parts of Winston Heights–Mountview. It’s imperative that everyone in our community is aware of the possible impacts and participates in the consultation process.
Please share this email with your friends and neighbours in the community, and encourage them to join our mailing list to stay informed.

Next Steps for the Committee
Once we know what route options Enmax plans to include in their second application, the committee will decide whether to act as interveners again in the AUC process. If we proceed, we will once again engage McLennan Ross LLP to represent our community’s interests.
At this point, thanks to a generous community donor who provided a top-up, we currently have $15,000 held in trust with McLennan Ross for future use related to this project.
Our committee will continue to stay engaged in this process and share updates as new information becomes available. We strongly encourage residents to participate in the upcoming consultations to ensure our community’s voice is heard.
If you have questions or would like to share your thoughts ahead of the consultations, please contact Enmax at [email protected].
Thank you for your continued interest and involvement in this important project.
Warm regards,
Winston Heights–Mountview Powerline Committee
