Following the mid-August 2020 extreme heat wave and resulting outages, the California ISO, California Public Utilities Commission and California Energy Commission produced a preliminary root cause analysis report on Oct. 6, 2020, and have since completed their final analysis to confirm and supplement their preliminary findings. The final report is available on the 2021 Summer Readiness webpage at http://www.caiso.com/about/Pages/News/SummerReadiness.aspx.
The Final Root Cause Analysis report incorporates additional data analysis that was not available when the preliminary report was published and confirms the preliminary report's findings that the three major factors leading to the August outages were related to extreme weather conditions, resource adequacy and planning processes, and market practices.
The California ISO has scheduled a public call on Jan. 19, 2021, to provide stakeholders with an update on readiness efforts to improve grid reliability in anticipation of hot weather conditions expected in summer 2021. The ISO will also provide a high level summary of the Final Root Cause Analysis report. Stakeholders will have an opportunity to ask questions during this call.
The Jan. 19 update call will be recorded and the video file posted on the 2021 Summer Readiness webpage linked above for a limited time. The recording is for informational and convenience purposes only, and any related transcriptions should not be reprinted without the ISO’s permission.
