August 25, 2025 | Stakeholder Update

Based on the stakeholder feedback from the FFR+ Rationale Document published on June 18, the Stakeholder Session held on July 23, and subsequent follow-up discussions with stakeholders, the AESO is exploring additional concepts and associated product and procurement designs. The Addendum to FFR+ Rationale Document, posted today, presents these concepts and alternative designs. We are seeking stakeholder feedback on these, including whether they appropriately balance the four principles set out in the Electric Utilities Act (s. 17.1(2)) and whether they are in the public interest.

Purpose

We are engaging on the procurement of highly available Fast Frequency Response (“FFR”) to meet the requirements outlined in the amended Transmission Regulation, Alberta Regulation 86/2007, and the ancillary services provisions in the Energy and Utilities Statutes Amendment Act (Bill 52). Through this engagement, the AESO is seeking input on different product and procurement designs for highly available FFR to support full import flows on the Alberta-British Columbia and Montana-Alberta interties.

Background

We developed an initial preliminary design of FFR+, a highly available ancillary service to provide a near-instantaneous response to arrest frequency decline following an intertie trip. The “plus” reflects that FFR+ is always available and may include other grid reliability services that are not procured through a market. The AESO has developed FFR+ in response to the amended Transmission Regulation, which requires the AESO to make arrangements to procure ancillary services sufficient to support import flows of up to 800 MW capability on the Alberta-British Columbia intertie (which is expected to increase over time) and up to 300 MW on the Montana-Alberta intertie.

We currently procure FFR through voluntary arrangements that do not guarantee high availability. To meet the new requirements, the AESO is proposing to competitively procure up to 750 MW of highly available FFR+ through commercial contracts.

    We are proposing the following three questions be discussed in breakouts at the session. Do you agree?  If not, please provide input or suggest alternate questions along with rationale.

    1. What role should a FFR market play (if any) in satisfying the requirements of the Direction to support full import flows?
    2. Should stacking other reliability services not procured through a market be permitted using the same capacity procured for FFR?
    3. Should new assets supported through long-term FFR+ contracts be permitted to participate in the market following the expiry of the contract?  If so, under what conditions?

    Is there another design for an ancillary service that the AESO should consider that balance the four objectives from Section 17.1(2) of the Act to satisfy the obligations of the Direction Letter?

    Is there anything else you’d like the AESO to consider regarding the FFR+ design and to cover at the stakeholder engagement session?
