System Market Power Analysis Posted, Call 5/6/19; Comments Due 5/20/19


The California ISO has completed its analysis to assess the structural competitiveness of the ISO’s energy market and will hold a stakeholder call on May 6, 2019 to discuss the results. Comments are due by May 20, 2019.


In the 2019 Final Policy Initiatives Roadmap, the ISO committed to analyze the structural competitiveness of its energy market in response to concerns raised by the ISO Department of Market Monitoring (DMM). In the 2017 annual report, the DMM found indications of system-wide market power in the ISO energy market and projected system-wide market power conditions would grow in 2018. The ISO will hold a stakeholder call on May 6, 2019 to present its findings to stakeholders and determine if further actions are appropriate.


The report is available for stakeholder review on the Miscellaneous Stakeholder Meetings webpage at


Please submit comments to by end of day May 20.


A web conference will be available for stakeholder convenience. In addition, the call will be recorded and the video file posted on the initiative webpage 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.
