Normal Operating Procedures
Used during normal grid operations or, in some instances, to prevent an emergency, Normal Operating Procedures (NOPs) guide our operation of the bulk electric system (BES).
In general, we anticipate and plan ahead "normal" system events, and we make the documented procedures publicly available—with unrestricted access.
Abnormal Operating Procedures
We utilize Abnormal Operating Procedures (AOPs) during events triggered by malfunctioning software systems or another type of infrastructure problem affecting MISO or its members. These procedures may include, but are not limited to, the back-up process used when a particular system fails. The procedures assume the BES is not at risk and helps prevent potential risk factors. In general, we pre-determine these types of procedures and make them publicly available.
Emergency Operating Procedures
We use Emergency Operating Procedure (EOP) when an event occurs on the BES that is considered an emergency or results in emergency conditions on the BES. We make some of these available for public access.
We collect data from Market Participants to facilitate the development of models that support real-time operations. We also receive information used to ensure our IT systems maintain the ability to communicate with our Market Participants' systems. Specification Procedures describe what data is required and in what format it should be provided. We make these procedures public.
Protected Procedures (Semi-Public)
To access semi-public or protected procedures, log on to the MISO Extranet.
Temporary or Interim Operating Procedures
Temporary or Interim Operating Procedures must be implemented immediately or quickly enough to make the normal, controlled review and release process unfeasible. Therefore, we initiate review of these procedures in parallel with their posting. These procedures may be publicly available, protected or confidential, depending upon their nature.
