Tableau Outage – Maintenance

Posted: April 30, 2026

The Tableau tool and all public reports on the AER website, will be unavailable on Tuesday, May 5, 2026, from 4:00 p.m. to 6:00 p.m. as we perform maintenance on the Tableau server.  

If you have questions about the Tableau maintenance outage, contact the Customer Contact Centre by phone at 403-297-8311 (1-855-297-8311 toll-free) or by email at inquiries@aer.ca. 

This page lists notices of the filing of applications, application amendments, and notices of AER hearings.

A notice may tell you

  • what a project is about,
  • how to get more information about a project,
  • how to file a statement of concern,
  • how to request to participate in a hearing, and
  • what our filing deadlines are.

Most notices are on the Public Notice of Application page, which has automatically generated notices for most applications related to energy development.
