1 Standards Update WECC Board of Directors Technical Session December 5, 2007 Albuquerque, New Mexico Steve Rueckert Director of Standards

2 Standards Update How did we get where we are today? Energy Policy Act Mandatory Standards Some RMS Requirements were mandatory enforcement of existing NERC standards through the contractual RMS obligation Remainder were additional and/or more stringent WECC requirements Regional Standards Task Force (RSTF) formed to review remainder of RMS requirements Essential for reliability Well Defined

3 Standards Update How did we get where we are today? RSTF identified 8 RMS standards for translation to Regional Reliability Standards Went through the expedited WECC process Translated existing RMS requirements to a format acceptable to NERC and FERC WECC Board approved 8 Regional Reliability Standards for submittal to NERC and FERC

4 Standards Update How did we get where we are today? Tier One Standards conditionally approved by NERC and FERC Identified necessary changes for permanent replacements Remove RMS sanction table for enforcement Develop adequate measures for each requirement Add Violation Risk Factors Add Violation Severity Levels FERC expects WECC to complete replacement standards in about a year

5 Standards Update What happens if were not done in about a year? If we dont have replacement standards by June 2008, WECC will need to provide a full explanation why Possibly no serious consequences if: Solid reason is provided Plan for timely completion is provided Standards will not just go away Existing Tier One standards will stay in effect No changes to existing requirements FERC may allow WECC to continue enforcement via RMS sanction table – UNLIKELY? More likely that WECC will be ordered to use the NERC sanction table for enforcement FERC may impose high VRF and/or high/severe VSL

6 Standards Update What happens if were not done? WECC desires to have approved replacement standards ready for Board approval in April of 2008

9 Standards Update FAC-501-WECC-1 Transmission Maintenance Suggestion that annual review was too often DT does not agree and left requirement for annual review oAnnual review does not require annual modification oRequires review for need to modify oRequires review for confirmation that plan is being followed Some comments indicate the need for more clarity DT implemented changes to the standard intended to add the required clarity Believe this standard will pass OC ballot

11 Standards Update IRO-006-WECC-1 Qualified Path Unscheduled Flow Relief DT proposed to add the reliability coordinator as a responsible entity TOP experiencing congestion on a qualified path requests relief WebSAS tool would identify schedules to be cut RC requirement is to approve or deny request for congestion relief If the RC approves the congestion relief webSAS automatically issues Tag adjustments

12 Standards Update IRO-006-WECC-1 Qualified Path Unscheduled Flow Relief Comments indicate general support for RC involvement RC has wide area view RC should be the entity to approve or deny curtailments Initially there was pushback from the RCs DT meet with RC managers and addressed the RC concerns I believe this standard will pass OC balloting

15 Standards Update PRC-004-WECC-1 Protection System and Remedial Action Scheme Misoperation Comments continued Several comments questioning RC applicability RC removed from applicability Comments indicating reporting/documentation requirements were over burdensome DT did not make any changes Retained existing RMS reporting/documentation requirements I believe this standard would pass OC balloting
