Work Flow ShAG Subcommittees Develop White Papers Straw Voting ShAG Voting of White Papers TAC Approvals/ Appeals PRS Protocol/ Development TAC Approval Board Approval Board Appeals PUCT Appeals

White Paper Framework Key concepts written clearly with sufficient detail for later formation of:  Protocols  Operating Guides  ISO Procedures  RFP scope for necessary modification to ERCOT central systems Crafted with the design of other papers in mind

Myths to be Dispelled “We are taking our current system and throwing it away” Fact:  Many of the current settlement and customer registration systems will be largely untouched. This is primarily a “Package 1” modification “If we don’t find a way to streamline the process we won’t make it in time” Fact:  The original process required only 2 years and 4 months from the first ISONP meeting through the market being placed on line and included many changes not required in this process (single control area, customer registration, etc.)  Using the rule timeline gives us 2 years and 7 months

Also Important to Note Protocol changes for market redesign may not require large wording changes Small changes to Protocol language can have profound affects on required system changes Process used to implement the Protocol changes could be as important or more important than the Protocol revision process itself

Areas of the Protocols that should require no or minimal change Section 1: Overview Section 3: Open Access to the ERCOT Transmission Grid Section 8: Outage Coordination Section 10: Metering Section 13: Transmission and Distribution Losses Section 14: State of Texas Renewable Energy Credit Trading Program Section 15: Registration Section 18: Load Profiling Section 19: Texas Standard Electronic Transaction Section 20: Alternative Dispute Resolution Section 21: Process for Protocol Revision Section 22: Attachments

Role of Seams Representative Attend as many meetings as possible Inform groups of work going on in other groups that may affect them Inform internal groups in ERCOT who may be affected by changes being recommended

Timeline A timeline should be developed in the initial meetings of the ShAG to establish milestones and aid in determining progress It should include:  Protocol development  RFP development and bid process  Implementation  Testing  Production

Other Considerations Training for the market should be provided on various nodal market designs and differences operating in the US and elsewhere The first ShAG assembly should be a two day meeting  First day to ratify the ground rules and committee structures  Second day to fill chair positions and establish marching orders
