  1. MORCWG REPORT CMOPS Meeting January 5, 2005 Nancy Bellows for Martin Huang

  2. Overview • Three Items for Approval 7/7/2004 Posting Changes • Modification/Addition to MORC Sections 1.A.1, 1.A.6, 1.A.9, 1.A.10 • Modification to MORC Section 2.A.1 • Modification to MORC Section 3.A.6 • Three Recommendations • Timeline for Restoration of Reserves • Spinning Reserve from Load • Future of MORC

  3. Modification/Addition to MORC Sections 1.A.1, 1.A.6, 1.A.9, 1.A.10 and DefinitionsBackground (1 of 4) • Clearly Identify Type and Amount of Reserves Required • 2003/2004 MORC/MIC/ISAS White Paper • July 2004 Posting • 6 company comments and MORCWG responses

  4. Modification/Addition to MORC Sections 1.A.1, 1.A.6, 1.A.9, 1.A.10 and DefinitionsBackground(2 of 4) • Resultant Changes to Definitions for: • Load Responsibility • Interruptible • Contingency Reserve • Operating Reserve • Non-spinning Reserve • Regulating Reserve • Spinning Reserve

  5. [1] At least 50% of the Contingency Reserve must be spinning [2] Sum of generation delivered to or within a utility [3] Total import into a utility excluding Non-Interruptible energy import using Non-Interruptible transmission, the Contingency Reserve of which is the responsibility of the source control area [4] Total export from a utility excluding Non-Interruptible export, the Contingency Reserve of which is the responsibility of the source control area [5] Non-Interruptible energy imports using Interruptible transmission are not Interruptible energy imports

  6. Modification/Addition to MORC Sections 1.A.1, 1.A.6, 1.A.9, 1.A.10 And Definitions Recommendation • CMOPS approval of July 7, 2004 posting with minor editorial changes incorporating comments received.

  7. Modification to MORC Section 2.A.1Background • Continuity of service to load is the primary objective of the Minimum Operating Reliability Criteria. Preservation of interconnections during disturbances is a secondary objective except when preservation of interconnections will minimize the magnitude of load interruption or will expedite restoration of service to load. During disturbances, the primary objective is to minimize the magnitude and duration of load interruptions for the Western Interconnection. This may require load interruptions in local areas or controlled separation to avoid greater impacts to the Interconnection or to expedite restoration.

  8. Modification to MORC Section 2.A.1 Recommendation • CMOPS Approval of July 7, 2004 Posting

  9. Modification to MORC Section 3.A.6Background • Type of transaction. Parties providing and receiving the scheduled energy shall involved in the transaction shall clearly identify andagree upon the type of transaction being implemented (firm or interruptible), the control area(s) and other parties providing the operating reserve for the transaction, and shall make this information available to all control areas involved in the transaction.

  10. Modification to MORC Section 3.A.6 Recommendation • CMOPS Approval of July 7, 2004 Posting

  11. Timeline for Restoration of ReservesBackground • MORC Section 1.A.4 -- restoration of operating reserve shall not exceed 60 minutes • NERC Policy 1.B.3 – restoration of contingency reserve restored within 90 minutes following DCS • RMRG requested explanation and reconciliation of differences • MORCWG recognizes merit in further examination of request

  12. Timeline for Restoration of ReservesRecommendation • CMOPS assign risk and cost/benefit analysis to appropriate Work Group. • NOTE: Other solutions such as scheduling practices may achieve same result as changing restoration period.

  13. Spinning Reserve From LoadBackground • John Kueck (Oak Ridge National Laboratory) presentation on using load as Spinning Reserve with Cabin Creek as a one-year test case

  14. Spinning Reserve From Load Recommendation • CMOPS form small group with Compliance Monitoring Work Group, Performance Work Group, and MORC Work Group to work with Xcel Energy to develop a proposal for this one-year test. • Note: Group can grant the approval for exemption to determine if further approval such as RMS exemption is required.

  15. Future of MORCBackground • MORCWG asked to compare alternative approaches for WECC MORC. • Identified 4 alternatives: • Eliminate MORC/rely on NERC Operating Standards waivers. • Continue with MORC/change functional references per NERC Functional Model. • Align MORC with NERC Standards/retain more restrictive criteria • Align MORC with NERC Standards/retain all contents.

  16. Future of MORCRecommendation • MORCWG will review approved NERC standard template • If adequate recommend “align MORC with NERC standards, retaining all contents”. • If not adequate recommend “continue with MORC, changing functional references as per the NERC functional model”. • Prime consideration given to continuation of real-time power system operator understanding and ease of use.
