Notes:
Initial Comments
   Proposed Revision Request 1671 should be incorporated in Business Practice Manual for Reliability Requirements Version 83 published on May 1, 2026 and not Version 82 published on December 15, 2025.  Version 83 includes updates for Day-Ahead Market Enhancements and Extended Day-Ahead Market initiatives.

SCE sees minor corrections in the BPM PRR language.  Please see below:

On page 25 the added language “as described Default Resource Adequacy Rules, see section 13,” needs to have “in” inserted after “described” and before “Default”.

On page 28,  in the second bullet on page 28 immediately after the redlined insertion and before “ISO Tariff 40.8”  the word “of” should be removed.

On page 189 in Section 13, the BPM should include a definition of what default means under the  “Default Study” section.  This section should clearly identify the intended purpose is to be used by LRAs that don’t provide their own values for QC and PRM.   Without any definition of what default means, readers may potentially think the results by default apply to everyone.

On page 190 in section 13.1.1 in the third paragraph, CAISO should change the term “100% available rate” to “100% availability rate”.

Thank you for your comments.

We will apply these redlined changes to the most recent version on the BPM after this PRR completes the PRR process.

We will update the language as requested.

Thank you for your recommendation, we will add the following clarification to section 13:
"All resources participating in the CAISO RA program will undergo this study to determine default QC value.  However, these default rules only apply if LRAs do not provide QC criteria or a reserve margin for their jurisdictional LSEs, see section 3.2 for additional information."
