The following outlines the configurable parameters and their values effective as of May 1, 2026.​​

Notes:
Initial Comments
The Six Cities note that similar language, with slightly expanded language for the final paragraph of the section, appears in the revised version of the BPM proposed for adoption in PRR 1668. The Six Cities recommend that the CAISO utilize the expanded version of the final paragraph proposed in PRR 1668, because it is more precise.
