    Fast Frequency Response

    Recent Materials 

    New technologies present an opportunity to provide FFR service.

    The AESO launched a Fast Frequency Response (FFR) from new technology pilot procurement competition (FFR Pilot Competition) targeted at procuring service from any new technology capable of meeting the FFR eligibility and technical requirements. The AESO announced the FFR Pilot through its Energy Storage Roadmap progress updates and the learnings from the FFR Pilot will support the long-term implementation of a FFR service.

    The FFR requirements for pilot participants are based on Load Shed Service for imports (LSSi) but have been adapted for new technology, such as energy storage. Service providers need to respond within 12 cycles (0.2 seconds) when a system frequency of 59.5 Hz is detected. A fast increase in real power output is expected in response to an underfrequency event. Underfrequency detection and event recording is also required to provide the service, and a SCADA system will be used to participate in the service.

    The AESO has coordinated with the Market Surveillance Administrator (MSA) regarding enabling provision of the service from new technology (other than load) within the current ISO Rules for the duration of the pilot and has posted a letter that provides further detail.  Upon the conclusion of the FFR Pilot, the AESO will provide an update to the Alberta electric industry and the public on the outcome of the FFR Pilot.

    FFR Pilot Competition

    The FFR Pilot Competition launched on March 24, 2021 with the Request for Proposals stage, and the proposal submission deadline was May 3, 2021. The AESO successfully completed the competitive procurement and contracts were awarded to two (2) successful bidders who submitted qualified proposals. The two successful proponents, their respective facilities and contract volumes are listed below. 

    Successful Proponents

    Proponent Name, FFR Facility Name

    Contract Volume (MW)

    Canadian Hydro Developers Inc.

    Summerview WindCharger (SUM1)

    10

    WCSB Power Holdings LP

    eReserve1 (ERV1) Rycroft

    The service term with each successful bidder is one year, which is targeted to commence as early as August 16, 2021, but no later than March 15, 2022. 

    The FFR Pilot Competition was overseen by a Fairness Advisor at every stage to ensure the competition, including the evaluation process, was administered in a fair and open manner and adhered to good industry procurement practices, strict confidentiality requirements and applicable policies and guidelines. To read the Fast Frequency Response Pilot Procurement Competition Fairness Advisor Summary Report, please click here.
