1. WECC Glossary Rachel Sherrard RPIC Meeting February 19, 2009

2. Current Glossary Contains WECC and NERC definitions even when the definitions are the same or very similar Issues Stakeholders must use the NERC definition when creating or complying with standards so having both definitions in one document causes confusion WECC is not notified when NERC definitions change, so NERC definitions in the WECC glossary can be outdated WECC glossary has never been through a formal review by a WECC committee or the WECC Board of Directors 2

3. Current Status Glossary is under review as part of WECC Web site redesign and WECC Style Guide development Definitions of NERC-defined terms have been removed (118 in total) and a link to the NERC glossary provided (see next slide for example) Definitions that remain are unique to WECC and are the subject of current internal review Entire glossary - review and approval by RPIC Subsequent to RPIC approval - present to WECC Board for approval and sign off 3

5. Process Going Forward Glossary reviewed annually New terms defined through the NERC standard development process will be added and the definition provided via a link to the NERC glossary New terms defined through the WECC standard and regional criteria development process will be added to the WECC glossary Any other new terms will be subject to internal review and approval by RPIC RPIC will present to WECC Board for approval and sign off 5
