Alberta (AESO)

No comment window closes in Alberta this week. The business that matters is a pair of windows that close together on Friday, September 4, with a run of scheduled steps to watch between now and then.

The through line: September 4, twice

Alberta's next comment deadlines arrive as a pair. Comments on the ISO Tariff Redesign Regulatory Consultation and on Interconnected Electric System Protection Requirements are both due by Friday, September 4. Two consultations sharing one deadline at least keeps the calendar entry simple; anyone planning to file on both now has under three weeks to draft twice for the same day.

What moved

The comment window on the Development of Proposed Amended Definition of “inflexible block” in the ISO Rules closed on August 13.

Coming up

Today, Monday, August 17: the Drafting Team meets on WECC-0160: WECC IBR Modeling and EMT Screening Criteria.

Friday, August 21: AESO Funding for Participation in the REM Rules Engagement reaches its Confirmation of Eligibility step.

Wednesday, August 26: the next scheduled step on Amendments to ID #2012-006R, Adequacy, Supply Shortfall and Energy Emergency Alerts.

Friday, August 28: a formal feedback summary is scheduled on the 2026 Long-Term Outlook Plan (LTO).

The wide view

The tracked list for Alberta stands at 43 open items. It ranges from the 2027 Budget Development Process and the Engagement Plan to REM IT Systems Implementation and the Grid Readiness, Integration & Performance (GRIP) Requirements, with the “inflexible block” definition work still on the list now that its comment window has closed.
