BREAKER BRIEF
WEEK OF SEPTEMBER 7 TO SEPTEMBER 13, 2026 | BREAKERBRIEF.COM
Alberta (AESO)
A quiet week on paper: nothing closes in the next seven days, two comment windows closed on September 4, and the next dated step does not arrive until October 1.
What moved
Two comment windows closed on September 4. The ISO Tariff Redesign Regulatory Consultation and the Interconnected Electric System Protection Requirements consultation are now past their comment deadlines; if you meant to file on either, that window has closed.
The optimal transmission planning consultation, open last week, is no longer on the open list.
Coming up
October 1 The service term commences for Market-Based Fast Frequency Response.
The wide view
Alberta still has 47 items open and tracked, among them Locational Marginal Pricing, the ISO Tariff Redesign Regulatory Consultation, the 2027 Budget Development Process, the proposed amended definition of "inflexible block" in the ISO Rules, and the amendments to ID #2012-006R on adequacy, supply shortfall, and energy emergency alerts. A week with no deadlines is a good week to read one of them properly.
