1. RMS Directive: TTPT Chair and Vice Chair to modify existing Market Testing Escalation Procedures sufficient to be a “starting point” for RMS members and Market Participants to use to develop Retail Market Escalation Procedures.

2. Our Process… • Reviewed existing TTPT Escalation document used in Flight 1001 • Identified what we considered “foundation” concepts in the Market Testing Escalation process • Reviewed “foundation” concepts to determine if these were relevant to production. • Agreed on portions of the document that could be made clearer. • Agreed on concepts (work in progress) that should be included. • Began a revision of the document taking into consideration all items identified above. • Included a draft of a organizational slide of communication structure that document supports.

3. Foundation concepts of the Market Testing Escalation Process that we considered good foundation concepts for a Retail Market Escalation process. Encourages Market Participant and/or ERCOT to remedy prior to escalation process being put into effect. Provides for ability of Market Participant and/or ERCOT to remedy after escalation process has been put into effect. Provides for ability of Market Participant to continue to operate while resolution procedures are ongoing. Identifies the need for an independent centralized entity to manage and monitor and assist with communication when necessary. For the purposes of this process, in the document this entity is identified as the Central Resolution Market Authority (CRMA). ERCOT Management is the entity that governs those involved in this process including the CRMA. Once escalation procedures are put into effect, the Centralized entity must work in cooperation with Market Participants and ERCOT Management until issues/problems are resolved. Streamlined process that is easy to execute - easy to close. Plan is not in conflict with any other Market rule, Guideline or Protocol that requires Market Participants to resolve issues/problems/disputes.
