  1. FERC Orders and NOPRS2010 Kenneth Wilson WECC Staff Reliability Subcommittee Meeting January 13-14, 2011

  2. Overview FERC Orders BAL-002-WECC-1 (Contingency Reserves) Docket No. RM09-15-000; Order No. 740 FERC NOPRS IRO-006-WECC-1 (Qualified Transfer Path Unscheduled Flow Relief Regional Reliability Standard) Docket No. RM09-19-000 TOP-007-WECC-1 (System Operating Limits) FERC Docket No. RM09-14-000 FAC-501-WECC-1 (Transmission Maintenance) FERC Docket No. RM09-9-000 PRC-004-WECC-1 (Protection System and Remedial Action Scheme Misoperation FERC) Docket No. RM09-9-000 VAR-002-WECC-1 (Automatic Voltage Regulators) FERC Docket No. RM09-9-000 VAR-501-WECC-1 (Power System Stabilizer) FERC Docket No. RM09-9-000

  3. FERC Orders October 21, 2010

  4. BAL-002-WECC-1 • FERC Remanded the Standard • Main Reason: Removal of the 60 Minute Reserve Restoration Period to adopt NERC 90 Minute Reserve Restoration Period

  5. BAL-002-WECC-1 • Justification Why? • Extension of reserve restoration period not justified • Potential increase risk to Western Interconnection Reliability • There have been six instances when a second major contingency occurred during the extended time period during the last 15 years • Significant number of transmission paths in the Western Interconnection are voltage or frequency stability-limited • Reliance on paths that are stability-limited to deliver reserves (Stability-limited paths have no emergency ratings like thermally-limited paths.)

  6. BAL-002-WECC-1 • FERC agreed with the contingency reserve concept of the greater of • The most severe single contingency, or • Sum of 3% of BA load and 3% of BA net generation • Clarity added to the contingency reserve standard by removing the term “load responsibility” and including renewable energy • Allowed Firm Load as Contingency Reserves but only under EOP-002-2.1

  7. BAL-002-WECC-1 • FERC Directed • Submit modification to allow demand-side management that is technically capable of providing service as a resource for contingency reserves • Use Operating Reserve – Spinning and Operating Reserve – Supplemental rather than Spinning Reserve and non-spinning reserve • NERC is ordered to solve confusion between definitions for Spinning Reserve and Operating Reserve Spinning and Non-Spinning Reserves and Operating Reserves-Supplemental

  8. Where are we Headed with BAL-002-WECC-1? • Formed Project WECC-0083 to incorporate FERC directives in the Order • WECC Board directed submission of a revised BAL-002-WECC standard by June Board meeting

  9. FERC NOPRS

  10. FERC Issued NOPRs Approving • IRO-006-WECC-1 (Qualified Transfer Path Unscheduled Flow Relief Regional Reliability Standard) Docket No. RM09-19-000 issued October 21, 2010 • TOP-007-WECC-1 (System Operating Limits) FERC Docket No. RM09-14-000 issued December 16, 2010 • FAC-501-WECC-1 (Transmission Maintenance) FERC Docket No. RM09-9-000 issued December 17, 2010 • PRC-004-WECC-1 (Protection System and Remedial Action Scheme Misoperation) FERC Docket No. RM09-9-000 • VAR-002-WECC-1 (Automatic Voltage Regulators) FERC Docket No. RM09-9-000 • VAR-501-WECC-1 (Power System Stabilizer) FERC Docket No. RM09-9-000

  11. IRO-006-WECC-1– Qualified Transfer Path Unscheduled Flow Relief • Commission seeks comments if it should direct WECC to: • Require steps 1 through 3 of the Unscheduled Flow Mitigation Plan (UFMP) in IRO-006-WECC-1 or TOP-007-WECC-1 (i.e. use of phase-angle regulators, series capacitors, and back-to-back DC lines to mitigate unscheduled flow) • Include references to the UFMP in the standard • Provide more information on the webSAS tool to prevent conflicts with NERC’s IRO-006-4 • Questions possible automatic approval of curtailments without reliability coordinator (RC) review • Revise UFMP to incorporate all the WECC rules and procedures or incorporate UFMP into IRO-006-WECC-1 • Questions role of Reliability Coordinator – Can RC issue a curtailment Request?

  12. TOP-007-WECC-1– System Operating Limits • Commission is requesting industry comment to address the following concerns: • Whether the standard would allow transmission operators to operate the system a single contingency away from cascading for up to 30 minutes • The change in time allowed to respond to a stability limited system operating limit from 20 to 30 minutes • The substitution of system operating limit for operating transfer capability. (Is confusion caused with Path Rating Catalog using OTC and standard using SOL?) • Replacement of the WECC Transfer Path Table with an internet link, which may permit changes to the table without Commission approval. • Change Violation Risk Factors to align with NERC Procedures • Should the SOL requirement apply to only elements on the paths or to all elements outside the path.

  13. FAC-501-WECC-1 – Transmission Maintenance • Commission is requesting industry comment to address the following concerns: • The WECC Transfer Path Table could be changed without review and approval of the ERO and the Commission • The substitution of system operating limit for operating transfer capability. • Is using OTC more appropriate than using SOL? • Will using SOL require more Transmission Owners to have transmission maintenance and inspection plans? • Would the owner of a major path be responsible for maintaining and inspecting transmission facilities owned by others? • Replacement of the WECC Transfer Path Table with an internet link, which may permit changes to the table without Commission approval.

  14. PRC-004-WECC-1 Protection System and Remedial Action Scheme Misoperation • Commission is requesting industry comment to address the following concerns: • The WECC Transfer Path and RAS Tables could be changed without review and approval of the ERO and the Commission • Questions whether the proposed terms Functionally Equivalent Protection System and Functionally Equivalent RAS are more inclusive than corresponding terms in NERC Glossary • Questions whether the proposed terms Security-Based Misoperations and Dependability-Based Misoperations are necessary

  15. VAR-002-WECC-1 – Automatic Voltage Regulators • Commission is requesting industry comment to address the following concerns: • Replace the blanket 2% exemption with a list of specific exemptions • More narrowly tailor the exemption for synchronous generators and condensers that operate less than 5% of the hours in a quarter • Questions the need to extend the AVR replacement period from 15 to 24 months for all generators if extension is only needed for nuclear units • Impact of removing the requirement that all generators with automatic voltage control equipment be operated in automatic voltage control mode set to respond to voltage deviations

  16. VAR-501-WECC-1 – Power System Stabilizer • Commission is requesting industry comment to address the following concerns: • Replace the blanket 2% exemption with a list of specific exemptions • More narrowly tailor the exemption for synchronous generators and condensers that operate less than 5% of the hours in a quarter • Questions the need to extend the PSS replacement period from 15 to 24 months for all generators if extension is only needed for nuclear units • Direct ERO to develop a continent-wide reliability standard that if a PSS is installed, the PSS must be properly tuned
