Reference Architecture for the ISO, RC and RTO industry

Version 1

    ISOs (Independent System Operators), RCs (Reliability Coordinators), and RTOs (Regional
    Transmission Organizations) are responsible for coordinating the delivery of bulk
    electric power. Configuration and access to their systems are usually subject
    to NERC CIP regulations. These organizations require HA (High Availability) of
    their control and monitoring systems. This usually drives them to employ
    redundancy and geographic diversity.

    This ISRA (Industry Specific Reference Architecture) for ISOs, RCs, and RTOs shows
    the OSIsoft PI System™ software components distributed among separate hosts to isolate
    functions, enable routine configuration of rigorous security policies, and simplify
    updates. This ISRA also shows how to employ redundancy and geographic diversity
    to meet requirements on availability.
