  1. CRR Issues Restructured/Reformatted Requirements - VOTE McFRIs Allocated to Wind Generators Effective Date for Settlement Points TPTF September 10, 2007

  2. Timeline of CRR Document Reviews & Approvals 1 2 Done NPRR047 and NPRR059 require TPTF approval and updates to the following: • Requirements • Conceptual System Design (CSD) EDS Handbook requires TPTF review and approval Renumber Requirements for traceability purposes and obtain TPTF approval. Business Process Clarification NPRR TPTF / CRR Issues

  3. Why did we Restructure Requirements? The initial efforts are focused on Protocol coverage by functional requirements… • CRR Requirements as approved do not provide the level of granularity to ensure traceability through test cases and scripts. • A finer level of granularity (lower number of tests scripts per requirement) will provide greater visibility to stakeholders, including TPTF and program leadership, into CRR System quality and test execution. • CRR Project Team chose to keep as much of original approved language as possible. In Quality Center In Requisite Pro Approved Test Cases Approved Requirement Documents Approved Use Cases Approved Test Scripts Test Results Protocols TPTF / CRR Issues

  4. Disposition of Comments Comments received during consideration of Baseline 1&2 revision to CRR Requirements No additional comments were received to the Reformatted Requirements TPTF / CRR Issues

  5. Proposed Motion • TPTF approves v2.5 of the CRR Requirements, as distributed to TPTF on August 29. TPTF / CRR Issues

  6. MCFRIs: allocated to WGRs, or QSEs representing WGRs? The procedures for determining McCamey Flowgate Rights (MCFRIs) and allocating them to QSEs representing wind-powered Generation Resources (WGRs) MCFRIs are a type of FGR that must be allocated only to WGRs in the McCamey Area, ERCOT shall identify WGRs eligible for MCFRI allocation in the McCamey Area ERCOT may allocate MCFRIs only to WGRs in the McCamey Area. • All CRRs, including MCFRIs, will be awarded to CRR Account Holders • QSEs and WGRs may each have an associated CRR Account Holder TPTF / CRR Issues

  7. MCFRIs: allocated to WGRs, or QSEs representing WGRs? CRR AH registration deadline Standard Form Agreement deadline Allocation Eligibility Form deadline Bus Process Clarification NPRR review Start of EDS testing TPTF vote on NPRR Market notice 12/1/07 1/15/08 2/4/08 10/24/07 End Sept 10/8/07 10/15/07 ~ 1 month ~ 2 months • Deadline to submit Allocation Eligibility Form (to participate in EDS PCRR and MCFRI allocations) is Dec 1st 2007 • Plan is to make Allocation Eligibility Forms available by end Sept, along with a market notice • However, Business Process Clarification NPRR (which determines whether MCFRIs are allocated to WGRs or QSEs) will only be approved on Oct 24th, at earliest • Options – either: • Wait for NPRR approval => Allocation Eligibility Form submission window = ~1mth, OR • Assume WGRs => Allocation Eligibility Form submission window = ~2mths TPTF / CRR Issues

  8. Effective Date for Resource Node Settlement Points • ERCOT proposes that Settlement Points associated with Resource Nodes not be established until generation is actually produced • This means that CRRs will not be available from or to that Settlement Point for at least a full month after the generator first produces electricity to the grid. • Timeline shown is for November CRRs • Generator would have to be online early September TPTF / CRR Issues

  9. Rationale for ERCOT’s position • Supporting two sets of Settlement Points – one for CRR, another for daily market operations – introduces a level of complexity requiring multiple sets of start and stop times associated with each Resource Node Settlement Point. • There’s a risk of adding a CRR Source/Sink based on projected information, selling CRRs which include that Source/Sink, and then not having the Settlement Point in-service. TPTF / CRR Issues

  10. Section 7.5.1 (2) / with proposed modifications • For a monthly CRR market, transmission system upgrades and changes shall be included in the CRR Network Model only if the upgrade or change is in-service when the CRR Network Model is being developed. • For an annual market, transmission system upgrades and changes shall be included in the CRR Network Model used for the first month after the upgrade or change is scheduled to be in-service for a full month.
