  • Post five-day process price corrections
    Since the start of the new California ISO market design on April 1, 2009, there have been isolated instances in which market prices were corrected outside of the five-day Price Correction Time Horizon. The ISO has not previously published the criteria used to evaluate whether a price correction is warranted after the expiration of the Price Correction Time Horizon. Through this initiative, the ISO will work with stakeholders to determine the circumstances under which post five-day price corrections may be made.
