    Pool price errors

    The AESO identified that the posted pool prices on October, 19, 2020 for hours ending 16, 17 and 18 were inaccurate due to a rare data scenario in the dispatch tool. This scenario caused an increase of transmission constraint rebalancing volume, resulting in the inaccurate pool price. The pool prices on October 19, 2020 for hours ending 16, 17 and 18, have now been revised and are reflected on the AESO website as follows:

    HE
    Originally Published Pool Price
    Corrected Pool Price
    Oct 19, 2020 HE 16  $35.79   $36.91
    Oct 19, 2020 HE 17  $42.38   $44.90
    Oct 19, 2020 HE 18 
    $37.98    
    $38.17

     

    The AESO will be implementing an update to the dispatch tool to mitigate any potential future issues caused by this rare scenario.
