Purpose
The AESO is seeking to procure up to 140 MW of dedicated Islanded Fast Frequency Response (FFR) services for when the Alberta Interconnected Electric System (AIES) is weakly connected to or islanded from the rest of the Western Interconnection (Islanded FFR Services). The Expressions of Interest stage of the competition closed on May 21, 2024, with a strong response from market participants, indicating availability of over 700 MW.
Islanded FFR Services Overview
Islanded FFR Services support frequency in the event Alberta experiences a severe single contingency during planned or unplanned outages on transmission line 5L92 or transmission line 1201L. The duration of planned and unplanned line outage periods varies year to year, but the AESO anticipates that Islanded FFR Services will be required between 10–20 days per year (tentative outages impacting interties are posted on the AESO website).
The AESO is seeking to procure up to 140 MW of dedicated Islanded FFR Services with a service term commencing January 1, 2025. The Request for Proposals stage of the competition, which will be managed through a procurement site called Bonfire (Bonfire site), opened on June 14, 2024. To obtain access to the Bonfire Site, view the RFP documents and participate in the RFP process, participants will need to request access, execute an access agreement and register.
