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.​
