Operating procedures guide rules and policy implementation

Operating procedures implement the policies and authorities contained in the California ISO Tariff and business practice manuals. We provide public access to current versions of the operating procedures, which do not contain information that is system security sensitive, market sensitive or third party proprietary. Operating procedures are intended to guide ISO stakeholders regarding the implementation of rules and policies specified in the California ISO Tariff.

TERMS OF ACCESS

The Shift Manager will determine the need for such deviation. The ISO reserves the sole right to revise or edit these procedures in accordance with Operating Procedure 5510.
