The California ISO has posted new proposed revision requests (PRRs) reflecting edits to Business Practice Manuals (BPM). Revised BPMs that have completed the BPM change management process are posted in the BPM Library.
All PRRs and related activity are publicly available through the BPM change management site at http://bpmcm.caiso.com/Pages/default.aspx.
New Feature: BPM PRR updates will now be part of the ISO Daily Briefing in addition to being listed in the “Announcement” sections of the BPM change management tool. These updates will include PRRs that have become available for review, upcoming BPM meetings, and comment due dates. All registered BPM users should continue to reference the BPM Change Management tool to see current PRR status.

BPM Library updates
The reference document on the ISO website lists the updated BPMs in the library.
The ISO may unilaterally make and implement revisions to the BPMs in emergency circumstances, as set forth in Sections 22.4.3 and 22.11 of the ISO Tariff and in Section 2.6 of the Business Practice Manual for BPM Change Management. An emergency PRR will continue through the BPM change management stakeholder process to obtain stakeholder input on the revisions and make other recommendations, as necessary.
Please note that affected parties must register in order to submit a PRR or written comments.
More information on the BPM change management process is available on the ISO website at http://www.caiso.com/rules/Pages/BusinessPracticeManuals/Default.aspx.
