The California ISO has posted a new document that supports the Day-Ahead Summer Report by providing an explanation of information included in the report. The Day-Ahead Summer Report is published during the months of June through September and is available on the Reports and Bulletins webpage, under the Market performance reports heading, Day-ahead daily market watch and summer reports subheading. The new document, Explanation of data included in the Day-Ahead Summer Reports, is located at the top of the reports.

The Day-Ahead Summer Report provides market participants with selected metrics on market performance to facilitate dissemination of market information in a timely manner. This report will be decommissioned once the transparency enhancements to provide this data through OASIS is implemented, which is targeted for mid-June 2022.
