The California ISO's change management process facilitates the transparent exchange of ideas and information when the ISO considers modifications to its Business Practice Manuals (BPMs). Use this site to submit and view Proposed Revision Requests (PRRs) and their statuses and to access the BPM library.
- The purpose of BPMs is to set forth business practices that implement the ISO tariff. The ISO conducts a yearly policy initiative roadmap process to consider and rank initiatives.
- Policy changes submitted though the PRR process will be referred to the policy initiative road map process. Each subject area in a BPM is based on enabling language in the ISO tariff.
- The PRR process cannot be used to introduce changes that are not supported by existing tariff authority.
