The California ISO has posted new proposed revision requests (PRRs) reflecting edits to Business Practice Manuals (BPM).

All PRRs and related activity are publicly available through the BPM change management site at http://bpmcm.caiso.com/Pages/default.aspx.

The PRRs listed below have an open 10-business day comment or appeal period from Feb. 19, 2019 through March 5. Due to the timing of submission, these PRRs will be discussed during the March and April BPM change management monthly meetings.

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.
