Commitment Cost Bidding Flexibility workshop on 6/18/26

The California ISO has scheduled a June 18, 2026, Commitment Cost Bidding Flexibility (CCBF) workshop. The workshop will focus on enhancements to commitment cost offer mitigation, and follow-up items from the previous meeting. Please submit written comments by end of day July 2, 2026. 

The CCBF workshop series will revisit enhancements to commitment cost offer mitigation. During the recently concluded gas resource management stakeholder initiative, the ISO committed to pursuing implementation of existing policy that was approved by the ISO Board of Governors with advisory approval from the WEM Governing Body. This policy supports more bidding flexibility with a dynamic market power test for commitment cost offers. 

The stakeholder meeting on June 18, 2026, the second in a series of workshops, will primarily review the technical market design elements of the existing policy for commitment cost market power mitigation. 

Meeting materials will be available prior to the meeting on the Commitment Cost Bidding Flexibility initiative webpage. The working group will be recorded and the video file posted to the initiative webpage. The recording is for informational and convenience purposes only, and any related transcriptions should not be reprinted without the ISO’s permission.

Please submit written comments on the workshop by end of day July 2, 2026, through the ISO’s commenting tool using the link on the initiative webpage linked above.

A voluntary survey is also available for stakeholders to submit questions regarding policy documents. Completion of the survey is optional and is not required to participate in the stakeholder process.
