MISO Dashboard

A Market Participant expressed concern that MISO Operating Guides should have greater transparency.  The issue has been raised to the Advisory Committee by the Market Participant.  In reviewing the issue, MISO notes there is a delicate balance between different classifications of information and the protection of certain classes of information and there is merit in discussing the issue with stakeholders.  MISO Operating Guides contain a combination of Critical Electric Infrastructure Information (“CEII”) and market sensitive information that could be used to gain a market advantage, so the guides are only accessible to those with MISO Extranet access and are not accessible to Market Participants.  The MISO Transmission Owner Agreement (“TOA”) also provides that all “non-public transmission and reliability” information and “information supplied in connection with MISO’s coordination center(s) operations” is confidential and prohibits disclosure of “information regarding the Transmission System covered by the Tariff”, subject to a few limited exceptions.  Therefore, providing the information found in the Operating Guides would likely be precluded by the TOA. The Market Participant has raised this issue because it does have access to CEII in other RTOs/ISOs, in particular PJM and NYISO.  PJM and NYISO have developed a process for separating out CEII and market sensitive information to allow disclosure of CEII to Market Participants.  MISO wants to provide stakeholders with the opportunity to consider increased transparency of Operating Guides to Market Participants.
