Western Renewable Energy Generation Information System
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)
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
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
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
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
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
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
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
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
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
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
