    Labelling Changes | Load Shedding Service for imports (LSSi) to Fast Frequency Response (FFR)

    In late September, the AESO will be changing the labeling on the Real Time Dashboard and Current Supply Demand (CSD) Report (Summary section) to reference FFR in place of LSSi. Specifically, the labels LSSi Armed Dispatch and LSSi Offered Volume will be changed to FFR Armed Dispatch and FFR Offered Volume, respectively.

    Additionally, the CSD Summary API will be changed to reference FFR in place of LSSi. Specifically, the lssi_armed_dispatch and lssi_offered_volume property names will be changed to ffr_armed_dispatch and ffr_offered_volume, respectively. For additional information visit AESO API Documentation.

    Additional information will be provided once specific release dates are confirmed.
