Business practice manuals detail California ISO operations

Business practice manuals (BPMs) contain the rules, procedures, and examples for the administration, operation, planning, and accounting requirements of the California ISO, in line with the ISO tariff. Following these manuals is important for the orderly operation of the ISO grid and market. The ISO’s change management process ensures the BPMs are the most up-to-date and comprehensive, and provides transparency into our decision-making process for participants, stakeholders, and the general public.

BPM change management process

The ISO systematic and publicly transparent BPM Change Management process ensures the consideration of all relevant information when modifying BPMs. The change management process uses a system available through the ISO public website that provides a way to propose BPM changes, comment on open change requests, and track proposed change requests. The change management process begins when the ISO or a stakeholder submits a web-based Proposed Revision Request (PRR). After an ISO review for completeness, PRRs are posted to the website, triggering a stakeholder review and comment period.
