2. What Is WREGIS? ● An independent, renewable energy registry and certificate tracking system for the Western Interconnect region ● WREGIS has two components:  Information system (software)  Administrative operations housed at the Western Electricity Coordinating Council (WECC)

3. How We Got Here ● Three policy drivers (2002-2003)  Western Governors’ Association  Resolution supporting creating an independent regional renewable energy tracking system  California Renewables Portfolio Standard  CEC charged with developing a regional certificate-based renewable energy tracking system to verify compliance  Western Regional Air Partnership  Endorsed establishing a regional institution to spur development of renewable energy to mitigate regional air pollution and haze

4. How We Got Here (Cont.) ● 2003-04  Regional stakeholder support emerged  Year-long process assessed needs for WREGIS and designed system functionality ● 2005-2006  Stakeholder and regulator vision execution ● Mid-2007  User-driven process in place  WREGIS Committee & Stakeholder Advisory Committee  “Go-Live” June 25th

5. WREGIS Territory and Scope ● Western Interconnect  14 states, 2 Canadian provinces, and a portion of Baja California  Alberta, Arizona, British Columbia, California, Colorado, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, South Dakota, Texas, Utah, Washington, Wyoming ● WREGIS is similar to other REC tracking systems across the United States

6. WREGIS Basics ● Generators, load serving entities, retail sellers, marketers, and others may open WREGIS accounts  Generators sign an agreement with WREGIS to report 100% of their generation  Certificates may be transferred within an account or to accounts of others  Certificates may be permanently retired

7. Regulatory Uses ● Helps regulators implement RPS  Utilities retire certificates to show compliance with renewable obligation or voluntary program  WREGIS allows user to specify reason for retirement  Use of WREGIS is free for Regulators ● Regulators use WREGIS data to verify certificates meet program eligibility  WREGIS does not determine program eligibility, but will record eligibility if State provides the determination

8. Regulatory Uses (Cont.) ● Provides reports to users and regulators ● Provides mechanism to incorporate RECs from small DG systems into programs ● Provides multi-year banking functionality  e.g., if program has “roll-over” provisions

9. Why is WREGIS Important? ● Policy neutral ● Uses independent and reliable data ● Helps states and provinces in compliance markets and with voluntary policies and programs ● Protects against double-counting  Increased credibility and consumer confidence

10. Who will use WREGIS for RPS? ● Currently several states and a voluntary program have either mandated use for RPS compliance or are recommending use for compliance on some level  California  Montana  New Mexico  Oregon  Washington  Green-e

11. Possible Future Uses of WREGIS ● Discussions regarding other uses are ongoing ● There is a possibility of adding emission tracking, not in WREGIS current scope ● White tag tracking is possible with alterations to the software ● With additional functionality, it could serve as a platform for tracking other environmental attributes in the west ● Policy must come first

12. Region vs. Nation ● Currently 6 regional tracking systems in place in U.S. and Canada ● Tracking systems currently account for state by state differences ● Software could be easily made compatible to enlarge renewable markets to nationwide
