Standards Update
WECC Board of Directors Technical SessionDecember 5, 2007
Albuquerque, New Mexico
Steve Rueckert
Director of Standards
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
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
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”
Standards Update What happens if we’re not done “in about a year?”
● If we don’t 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
Standards Update What happens if we’re not done?
●WECC desires to have approved replacement standards ready for Board approval in April of 2008

automatically issues Tag adjustments
