    Urgent: No
    Sections: 6.1 (new)
    Description: This Planning Guide Revision Request (PGRR) creates a new section in the Planning Guide to establish a process for creating and maintaining planning models referred to as steady-state base cases.
    Reason: There is currently no specific language in either the Protocols or Operating Guides related to the process associated with creating and maintaining steady-state base cases. Since these computer models are used for transmission planning it is deemed appropriate for inclusion in the Planning Guide in order to provide basic information to Market Participants related to the process of development of steady-state base cases for steady-state system simulations.
