The California ISO Department of Market Monitoring (DMM) posted the monthly Western Energy Imbalance Market (EIM) Resource Sufficiency Evaluation Issues and Performance Report. This report provides additional transparency surrounding test accuracy and performance for September 2021. DMM agreed to provide additional transparency surrounding test accuracy and performance in regular reports specific to this topic as part
of the EIM resource sufficiency evaluation stakeholder initiative.
This report, as well as the special report issued by DMM in May, summarizes some of the existing metrics that can be included in future EIM resource sufficiency evaluation reports. DMM is seeking feedback from stakeholders on existing or additional metrics and analysis that would be most valuable. Please provide feedback directly to DMM at dmm@caiso.com, or through the ISO’s EIM Resource Sufficiency Evaluation stakeholder process.
The May report, Resource Sufficiency Tests in the Energy Imbalance Market, is available on the ISO website.
